Kerala Agricultural University, Thrissur
The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively.
Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively.
On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs.
In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc.
During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU).
Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

ThesisItem Open Access Immunoglobulins in ducks and role of bursa of fabricius in their production(Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 1990) Krishnan, Nair G; KAU; Sulochana, SA study was undertaken to determine the immunoglobulin profile of ducks and to delineate the role of bursa in their production. Among the four different methods of bursectonomy employed in the study, Cy was found to produce the maximum reduction in body weight compared to other treatments. Marked reduction in bursal weight was also produced by Cy compared to T and ABS groups, while in SBx group the bursa was absent in toto. Surgical bursactomy resulted in significant reduction in spleen size of both surgically bursactomised uninoculated and inoculated ducklings. Histopathological studies revealed that the bursal development was highly suppressed on treatment with Cy. The ABS and testosterone treatments also elicited suppressive effect on bursa, but to a comparatively milder extent. It was evident that bursa had a role in lymphoproliferative reactions of spleen, as indicated by the maximum suppressive effect on spleen by SBx group. Ammonium sulphate at 33% level was found to be ideal for fractionation of duck serum globulins. Two main elution peaks were obtained on subjecting ammonium sulphate precipitated globulins to sephadex G – 200 chromatography. Concentrated and rerun ascending fractions of first major peak yielded purified IgM while those of the second major peak yielded purified IgG. Comparing the three age groups of antigen inoculation in ducklings bursectomised by different methods, total protein levels lower than the control were observed only in SBxSt (groups 1 and 11) and SBxSt (groups 1 and 111). Bacterial agglutination test revealed that in all four groups of bursectomised ducklings, antibody titres far below those of controls were produced. In SRBC agglutination test, lowered antibody titres than the control were observed in groups 1 to 111 of SBx, Cy and T – treated and groups 11 and 111 of ABS treated birds. Group 1 ABS administered ducklings had identical titres as that of control at days 7 – 21 post – inoculation. Bursectomized uninoculated ducklings revealed higher IgM levels than age – matched controls at many of the weeks under study. In bursectomised ducklings administered SRBC, IgM values higher than control level were obtained in the following cases : in groups 1 and 11 of SBxSR and TSR; groups 11 and 111 of CySR; and groups 1 to 111 of ABSR. S. typhimurium inoculated bursectomised ducklings revealed in the following treatments, higher IgM levels than control; in SBxSt groups 1 and 11; CySt groups 1 to 111; TSt group 1; and in ABSt groups 11 and 111. Quantitation of IgG levels in bursectomised ducklings revealed lower than control levels in SBx, Cy and T groups at 1 – 4 weeks of age, while the levels were higher or lower or identical with that of control from week 5. In ABS group the level was lower at 1 – 2 weeks. In bursectomised ducklings administered SRBC, higher IgG levels than control were obtained in groups 11 and 111 of SBxSR, CySR, TSR and ABSR. In group 1, treated ducklings revealed either lower or identical IgG levels compared to age matched controls. S. typhimurium inoculated bursectomised ducklings had higher IgG levels compared to CSt in all three groups of inoculation. Bile of ducks was found to contain only IgM, as evidenced by immunoelecrophoretic and quantitation studies. The IgM level in bile of bursectomised ducklings was found to be lower than that of the control. Yolk of duck eggs contained both IgM and IgG. Significantly higher lymphocyte count between the control and treated groups under study was detected at 4th (in SBx and T) and 8th weeks (in Cy). At 7th week, SBx group had significantly lower lymphocyte count, compared to control. At the fourth week of age, SBx and T groups had significantly lowered heterophil counts, compared to control. SBx group showed significantly higher count than the control at the 7th week, while at the 8th week, Cy – treated birds had markedly lower count, compared to the control. Eosinophil counts in bursectomised ducklings were higher than in control, while the basophil and monocyte counts in control and treated groups were more or less the same. The results obtained from the present study revealed that, 1. Among the different methods of Bx employed Cy produced maximum reduction in body weight, while SBx resulted in total elimination of bursa and significant reduction of spleen size. 2. Bursa had a role in lymphoproliferative reaction of spleen. Cy – produced maximum suppressive effect in bursa while in spleen SBx caused maximum suppression. 3. Ammonium sulphate (33%) was ideal for separation of duck serum globulins. 4. Sephadex G – 200 gel filtration was suitable for purification of IgM and IgG of ducks. 5. Bursa was concerned only with specific antibody production. 6. Elevated IgM and IgG levels were produced in bursectomised birds by extra – bursal B cells. 7. Bile of ducks contained IgM, the concentration of which was lower than the control in bursectomised birds. 8. Egg yolk of ducks contained both IgM and IgG.ThesisItem Open Access Seroprevalence and Restriction enzyme analysis of Egg Drop Syndrome virus(Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 2000) Priya, P M; KAU; Krishnan Nair, GIn the present study, seroprevalence of EDS-76 was conducted in five districts of Kerala in duck and' chicken flocks using HI and ELISA. Out of 322 chicken and 281 duck sera samples screened, an overall incidence of 14.91 per cent and 26.69 per cent respectively were recorded. The high proportion of birds showing antibodies to EDS-76 reveals that the infection is widespread in Kerala and may be the major etiological factor associated with drop in egg production in poultry. Among the two serological tests namely, HI and ELISA employed for the detection of EDS-76 viral antibody, HI was found to be simple, sensitive and reliable. It is concluded that HI test could be used for the detection of EDS-76 infection in poultry flocks. Restriction DNA fingerprinting of the three indigenous strains were carried out in conjunction with the reference strain to check for any genetic variation between the strains. Comparison of the DNA fingerprint of all the four strains digested with restriction endonucleases BamHI, EcoRI and HindIII revealed identical banding pattern thereby conforming the genetic similarity of the strains.ThesisItem Open Access Seroprevalence of HydroPericardium Syndrome in Broiler chickens(Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 2000) Binu, T V; KAU; Koshy JohnIn the present study, seroprevalence of hydropericardium syndrome (HPS) in broiler chickens in Kerala was evaluated. The results of agar gel precipitation test (AGPT), counter imrnunoelectrophoresis (eIE) and indirect enzyme linked imrnunosorbent assay (ELISA) were compared in detecting HPS antibodies. A total of 350 sera samples were collected from different parts of Kerala. In the first phase, 50 sera samples were screened by AGPT, eIE and indirect ELISA. Three samples were found positive by AGPT and eIE. Seven samples were found to be posi ti ve by indirect ELISA. Based on the comparison, another 300 samples were screened using indirect ELISA and 17 samples were found to be positive. A total of 24 samples were found positive for HPS antibodies out of 350 samples screened by indirect ELISA. The seroprevalence of 6.86 percentage was evaluated in broiler chickens in Kerala using indirect ELISA. The syndrome was experimentally reproduced in three-week-old broiler subcutaneous inoculation viz. , chicks. intramuscular, Various routes of and intraperitoneal routes were tried. The lesions were more pronounced when the birds were inoculated by subcutaneous route. Chick mortality was high on the fourth day. Electron microscopy of the infected liver homogenate revealed hexagonal virus particles of about 75 nm in size. These are suggestive of adenovirus. Histopathology of necropsied birds showed degeneration and necrosis of myocardial fibres, necrosis of hepatocytes and focal areas of coagulation in liver. Basophilic intranuclear inclusion bodies were demonstrated in hepatocytes. Vacuolar degeneration of kidney tubules, lymphoid depletion of bursa, vascular sclerosis of spleen and congestion and oedema of lungs were also seen.ThesisItem Open Access Characterisation of virus isolates from lesser whistling teals and channa species of fish(Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 2000) Pradeep, V; KAU; Krishnan Nair, GCharacterisation of virus isolates (T18 and T22) from lesser whistling teals (Dendrocygna javanica) and Channa species of fish (Fe and F12) was carried out to determine the similarities if any between the isolates and to identify the role of waterfowls in dissemination of these viruses. The virus isolates. preserved in the Department of Microbiology were revived by passaging through embryonated chicken! duck eggs through allantoic route. After the third passage, all the isolates were found to produce death of the embryos and the allantoic fluid collected agglutinated one percent chicken RBC. The isolates T18, Fs and F12 produced congestion of the embryo and CAM and the embryos showed sub-occipital and interdigital haemorrhages. Isolate T 22 also produced congestion of the embryo and CAM and the embryos were stunted. Liver of the embryos had yellowish brown patches. The EID50 of isolates were 3.2x10s, 5.6 x 105 , 1.65x 107 and 3.16 x 105 respectively for the isolates T18, T22. Fs and F12. The infectivity and haemagglutinating activity of all the isolates were retained at pH 7.2, but were completely lost at pH 3.2 and 9.0 and also by treatment at 56°C for 30 min. All the isolates were sensitive to chloroform indicating their enveloped nature. Pretreatment of chicken embryo fibroblast cultures with 1 OO~g! ml of luDR did not inhibit the multiplication of any of the isolates indicating they all had RNA genomes. All the isolates were resistant to treatment with brine indicating that they were capable of survlvinp at high salt concentration. The isolates T18 and Fa produced marked CPE in chicken embryo fibroblast culture with rounding and clumping of cells and syncytia formation. Marked cytoplasmic vacuolation was also observed. Inclusion bodies could not be detected either in nucleus or cytoplasm. For isolates T22 and F12, CPE developed later only and was not as prominent as for T18 and Fa. Rounding of cells and their fusion forming syncytia was noticed by 72 h. Cytoplasmic vacuolation though present was much less marked. Inclusion bodies were absent. Large polykaryocytes were produced by the isolates T18, T 22 and F12 in BHK-21 cell line within 24h after inoculation. Between 48-72h large syncytia were formed. Intracytoplasmic inclusions could be observed by 24h after infection, which were quite prominent by 96h. The isolate Fa failed to produce any CPE in BHK-21 cell line. Pathogenecity tests in day old and six-week-old chicken and ducklings showed that all the four isolates were non-pathogenic when given by the oral Isubcutaneous route or by both. Neither clinical signs or mortality could be observed in the birds. Virus isolation was possible from the cloacal swabs of six-week-old chicken for the isolates T18 and T22 up to the 14th and th day respectively. Antigenic relationship between the isolates was tested by gel diffusion and haemagglutination inhibition tests, which showed that the isolate T18 did not have any similarity with any of the other three isolates. The isolate T 22 showed antigenic similarity by both the tests. Fa showed similarity to T18 by HI test but not by immunodiffusion test. Isolate F12 was found to be distinct from the other three by HI test, but showed some similarity with them by immunodiffusion test. By sodium dodecyl sulphate polyacrylamide gel electrophoresis on 10 percent gels, 7-11 bands could be resolved for the different isolates. Three of the bands were common for all the four isolates and were having molecular weights similar to the three major proteins HN, NP and MP of avian paramyxoviruses, suggesting that the isolates belonged to the paramyxovirus group. Monoclonal antibody typing of the isolates T18 and T 22 at the Central Veterinary Laboratory, Surrey, England confirmed that both belonged to the paramyxovirus group with T18 belonging to group C (velogenic) and T 22 to group E (B1 and LaSota) viruses. The isolates Fe and F12 need to be further typed. It was concluded from the study that all the isolates were enveloped RNA viruses with T18 and T 22 being paramyxoviruses belonging to Group I. The properties of the isolates Fs and F12 resembled the paramyxoviruses and from the similarly in protein profile with the other two viruses can also be concluded to be paramyxoviruses.ThesisItem Open Access Enzyme immuno assay based seromonitoring and detection of canine rabies antigen(Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 1999) Biju, K G; KAU; Krishnan Nair, GIn the present study an attempt was made to measure the serum neutralizing antibodies against rabies virus in the sera of both vaccinated and unvaccinated dogs, employing ELISA. A long with this special emphasis was given to compare the results of diagnostic techniques used for yaJ.i.es namely Seller's staining and IP test. Four hundred and thirty-four sera samples from dogs of different age groups were screened. Enzyme immuno assay of sera of 83 unvaccinated pups revealed that under the age group of 0-3 months 59.1 percent antibody titre of 1: 50 or above indicating the presence of maternal antibodies. Out of 116 sera samples from primarly vaccinated group only eight had antibody titre below 1:50. Among the booster vaccinated 94 sera samples tested only four samples showed antibody titre below 1:50 .. The assay revealed that during diseases the immune systems of the dogs will be suppressed. It was found that the age of first vaccination could be decided as third month. The present study revealed that primary vaccination might not produces higher antibody titres in dogs. The study showed advantages of booster vaccination over primary vaccination. All the rabies suspected cases were subjected as two diagnostic tests namely Seller's staining and IPT. Out of 20 rabies suspected cases, there were detected by demonstration of Negri bodies and four were by IPT. The present study showed plate ELISA is a sensitive method for titration of rabies virus neutralizing antibodies and IPT can be successfully used for the detection of rabies antigen in impression smears taken from hippocampus.ThesisItem Open Access Molecular characterisation of salmonellae isolated from poultry(Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 2000) Tressa Mary, G; KAU; Punnose, K TFive serotypes of salmonellae from avian sources were examined for biochemical properties, serology, drug resistance, plasmids, restriction enzyme pattern of plasmid as well as genomic DNA and pathogenicity. The biochemical characters are in confirmity with the characters described for the serotypes by the earlier workers. The study of antibiogram with 20 antibiotics/chemotherapeutic agents revealed the presence of multiple drug resistance in all the five serotypes. In the plasmid analysis, S enteritidis and S. branderup were found to be plasmid free. The number of plasmids in other serotypes ranged from two to three and the size ranged from 1.75 kb to 48.32 kb. Identical low molecular weight plasmids were present in both S. gallinarum. The presence of large plasmid in one of the S. gallinarum did not confer any additional detectable resistance character. S. typhimurium contained two plasmids of sizes 13.62 kb and 4.2 kb. Restriction enzyme analysis of plasmid DNA from three salmonellae with EcoRl and Hindlll yielded three different restriction pattern with each enzyme. Ethidium bromide and exposure to elevated temperature cured the plasmids present in the salmonellae within two days and 14 days respectively. Acridine orange and sodium dodecyl sulphate were found to be ineffective in curing the plasmid DNA. The elimination of plasmids resulted in the loss of resistance to antibiotics was demonstrated in S. typhimurium. In tests to assess the differences in pathogenicity between wild and cured isolates of S. typhimurium in day old chicks, only intraperitoneal route was found to be effective when compared to oral route. A relation of plasmids to virulence was noted only in S. typhimurium. Day old chicks were refractory to infection to S. gallinarum by both the routes. Plasmids encoding both resistance and virulence were observed in S typhimurium. Plasmid negative serotypes of S. enteritidis and S. branderup were found to be equally virulent as wild strains of S. typhimurium. So a definite correlation between virulence and plasmids could not be made. Restriction enzyme analysis of chromosomal DNA yielded bands which were indistinct and so uncomparable. Hence of the tests based on the analysis of genetic content plasmid profile was found ,to be efficient in typing the isolate rather than restriction enzyme analysis of genomic DNA.ThesisItem Open Access Homology between corynebacterium psedotuberculosis isolates from goats and standard reference strain(Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 2000) Mohan, P; KAU; Jayaprakasan, VCorynebacterium pseudotuberculosis was isolated in pure culture on blood agar from pus collected from lymph nodes of goats, which suffered from caseous lymphadenitis. Three field isolates of C pseudotuberculosis were characterized and compared with standard reference" strain based on cultural, biochemical, toxigenicity, protein profile and restriction endonuclease digest analysis of chromosomal DNA. The morphological and cultural characters of all the field isolates and reference strain were similar and characteristics to the species. Biochemical reactions employed were also similar for all the strains except isolate F3, which fermented lactose. The biochemical characters were in confirmity with the characters described by the earlier workers. Three different types of toxin viz., culture filtrate (CF), whole cell lysate (WCL) and sodium chloride extract (SCE) were tested for dermonecro toxicity in rabbit skin. Among the preparations, the whole cell lysate produced a definite necrosis at the point of intradermal injection followed by culture filtrate and sodium chloride extract. The toxin preparations of the isolates invariably produced inflammatory and necrotic changes, the degree and severity of the reactions varied between samples. When the three toxin preparations of the isolates and reference strain were tested for synergistic haemolytic activity with Rhodococcus equi, the whole cell lysate produced maximum zone of haemolysis followed by culture filtrate and sodium chloride extract. The proteins presented in the different preparations were analyzed by SDS-P AGE. The protein profiles discerned by whole cell lysate, culture filtrate and sodium chloride extract were 25,9 and 9 protein bands with ranged on masses approximately 8-200KDa, 20-200KDa and 19-191KDa respectively. The 31.6KDa and 68 KDa proteins were found to be consistent in three toxin preparations. The DNA extracted from the isolates and reference strain were subjected to restriction endonuclease digestion employing Eco RI, Barn HI, BgI II, Eco RV and Pst I. The enzyme digest of DNA varied between the enzymes employed. There are no observable differences between the field isolates and reference strain, when the DNA digested with these five restriction enzymes. The enzymes Eco RI, Barn HI and BgI I presented similar restriction pattern whereas the DNA fragments generated by Eco RV and Pst I were different from the other three enzymes.ThesisItem Open Access Prevalence of yeast and yeast like fungi in bovine mastitis and their in vitro drug sensitivity(Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 1996) Sukumar, K; KAU; James, P CA total of 200 milk samples from clinical cases of bovine mastitis were culturally screened during a period of six months. Pathogenic fungal organisms could be isolated only from 26 samples. Out of this 26 positive samples, yeast and yeast like fungal organisms were isolated from 20 samples and mould from six cases. The major pathogen isolated were candida spp namely C. tropicalis, C. parapsilosis and C. guillermondi. The other organisms were Geotrichum candidum, Trichosporon cutaneum, Sacharomyces cerevisiae, Torulopsis spp and Rhodotorula rubra. The filamentous fungi isolated were Sepedonium spp, Aspergillus ochraceous group, Cladosporium carrionii, Penicillium spp and Trichophyton verrucosum. In majority of the cases yeast and yeast like fungi produced chronic mastitis in which hardness of udder and reduction in milk yield with watery milk containing flakes were noticed. In cases of mastitis where in mould was involved, chronic mastitis characterized by hardness of udder and reduction in milk yield with straw yellow coloured milk, viscid in consistency. Sensitivity pattern of the fungal isolates to the commonly employed antifungal chemotherapeutic agents like Amphotericin B, Clotrimazole, Fluconazole, Griseofuivin, Itraconazole, Ketocanazole, Nystin and Pimaricin (Natamycin) was elucidated. Among the above agents Clotrimazole and Itraconazole exhibited maximum inhibitory activity. All the isolates were found to be resistant to Griseofulvin. In vitro drug sensitivity pattern of fungal isolates employing the discs impregnated with essential oils of cinnamon, clove and lemon grass and alksloids of Cassia alata was studied. Cinnamon leaf oil possessed maximum antifungal activity and the extracts of Cassia alata failed to evince the ability to inhibit the growth of fungal isolates. The antifungal activity of plant extracts were compared with the commonly antifungal chemotherapeutic agents.ThesisItem Open Access Characterization of Campylobacter jejuni isolated from pigs and man(Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 1994) Raju, P V; KAU; Madhusoodanan Pillai, RTwenty six rectal swabs collected from piglets below two months of age with diarrhoea/enteritis when culturally screened yielded 11 isolates of Camplobacter jejuni. Thirty two rectal swabs from children below five years of age with diarrhoea/enteritis when processed for the isolation of etiological agent, resulted in the recovery of one strain of C. jejuni. Sonicated C. jejuni antigen prepared from the selected strains of C. jejuni from porcine and human origin were found suitable for sensitization of gluteraldehyde stabilized sheep RBC for serum antibody monitoring. The sonicated antigen retained its affinity to sheep RBC even after six months of storage at – 600 C. Gluteraldehyde stabilization was found to be a suitable method for the preservation of SRBC. Gluteraldehyde stabilized SRBC stored at 40 C upto a period of three months did not show any reduction in the sensitization property, as evidenced from the PHA titre. One hundred and fifty microliters of C. jejuni antigen whose protein concentration adjusted to 2 mg/ml was found to be the optimum level for sensitisation of a suspension made from three millilitres of packed SRBC. The optimum level of SAPA cells required in the seromonitoring of C. jejuni specific antibodies by SAPA – AMHA test was found to be 0.1 per cent. Cross titration assay employing homologous and heterologous antigens of C. jejuni and the hyperimmune sera indicated that there was antigenic relationship between porcine and human strains. The results also point to the probable prevalence of different antigenic components in varying proportions in different strains from various sources. In the present investigation, 50 serum samples from pigs were monitored for the presence of C. jejuni specific antibodies by PHA and SAPA – AMHA. PHA detected 48 per cent cases as positives compared to 54 per cent by SAPA – AMHA. Statistical analysis clearly indicated that SAPA – AMHA is superior to PHA in screening C. jejuni specific antibodies. The result of the present study indicated that SAPA – AMHA test could advantageously replace the conventional PHA for serological diagnosis of animal and human Campylobacteriosis. Efforts were also made in this study to find out the change in PHA titre with homologus and heterologous antigens employing sera before and after adsorption with unsensitised SRBC to remove the non specific antibodies. Statistical analysis of the results showed that for performing PHA, homologous antigen should be preferred over heterologous antigen and when homologous antigen were used, adsorption of sera with stabilized unsensitised SRBC had no significant effect of PHA titre. Attempts were also made to study the in vitro antimicrobial sensitivity patterns of the 12 C. jejuni isolates by standard disc diffusion technique. The results indicated all the C. jejuni isolates were sensitive to chloramphenicol, gentamicin and nalidixic acid, irrespective of their source/origin. Eventhough none of the C. jejuni isolated in this study was resistant to erythromycin, only 83.3 per cent of the isolates showed a sensitive zone of inhibition, while, 16.7 per cent showed an intermediary zone of inhibition. C. jejuni isolates recorded 83.3 per cent sensitivity to furazolidone, 75 per cent to streptomycin and 58.3 per cent to ampicillin. Fifty per cent of the isolates showed resistance to oxytetracycline. Of the ten antibiotics tested, 16.6 per cent of the organism were sensitive to penicillin. C. jejuni recorded highest resistance to sulphadiazine as only 8.3 per cent of the organisms were sensitive to sulphadiazine.
