ThesisItem Open Access Studies On Eimeria Tenella Infection In Poultry With Special Reference To Incidence And Immunoprophylaxis(Birsa Agricultural University, Ranchi, 1989) Deb, Asit Ranjan; B. N. sahaiOut of 1,200 poultry intestines examined, 228 intestines were found positive for tenella infection. The age-wise incidence revealed the highest (35.78 %) occurrence of infection in 0-3 months followed by 16,46 and 4.09 par cent in 3-6 and above 6 months age groups, respectively. The seasonal incidence indicated that 29.75, 16.25 and 11.00 per cent birds were infected with E. tanelle during monsoon, winter and summer seasons, respectively. It was also observed that the birds reared under intensive and free-range systems of management harboured 23.45 and 7.05 per cent infection. Thus, it was concluded that terella infection is common in age group 0-3 months in monsoon season under intensive manage mental condition. LETENSITY OF EINERIA ZENELLA INFECTION The moderate to intense infection of tonella vas observed in the birds of both 0-3 and 3-6 months age groups. There was non-significant (P>0.05) difference in the intensity of infection during monsoon, winter and summer seasons. Where as under intensive system of management moderate (+) intensities of infection was more (52.68 %) than that of other grades. But there was non-significant (P>0.05) difference of intensities under free-range system of management.ThesisItem Open Access Studies On Epidemiology, Host-Parasite Relationship And Immunity To Coccidial Infection In Goats(Birsa Agricultural University, Ranchi, 1989) Sinha, Rai Nandan Prasad; B.N. SahaiThe present study was undertaken to ascertain the incidence and intensity of coccidial infections in goats, their transmission in sheep and vice-versa, host-parasite relationship, chemoprophylactic control of experimental coccidiosis in kids alongwith attempt to immunize passively against the mixed coccidial infections in kids by immune serum transfer experiment. Incidence: The incidence of coccidia in goats in and around Ranchi was found to be 46.06 per cent after examining 1380 faecal samples and 157 intestinal scrapings of goats. The seasonal incidence of coccidia in goats indicated 64.62 and 50.29 per cent infections in rainy season under farm and village conditions, respectively. The incidence was highest in rainy season as compared to summer and winter seasons, which was statistically significant (P < 0.01). The coccidial infections in male and female goats were found to be 46.95 and 44.65 per cent respectively, which was statistically non-significant (P>0.05). The four breeds viz., Jamunapari, Beetal, Black Bengal and cross breds, under farm conditions did not show any impact on the incidence of coccidia. It was also statistically non-significant (P>0.05). The present investigation revealed highest incidence of 69.54 and 62.03 per cent in goats under six months of age in farm and village management conditions respectively.ThesisItem Open Access Studies On Pathology, Transmissibility And Chemotherapy Of Manage Infestation In Rabbits(Birsa Agricultural University, Ranchi, 1988) Bhattacharyya Debasis; A. BasuIn the present study, clinical manifestation and gross pathology of body coat were observed in both natural and experimentally infected rabbits at weekly interval upto 56 days post-infection. The incubation period was also observed in both groups of animals. In natural infection, the incubation period was 13 days, whereas, in artificial infection this period was seen to be 25 days. The site of onset of lesion, in natural infection group, was over the nose, whereas in experimentally infected cases the lesion started from the base of the ears, after which the spread of lesion was more or less similar in both groups. During first two weeks pei. the lesion was restricted on the facial region of the body. From third week onward, the lesions were seen on other parts of the body e.g. paws of hind and fore legs and external genitalia of both male and female. There were scab formation, alopecia and wrinkling of skin with dull, depressed and emaciated condition of the animals. On examination of the skin scraping, intensity of infection was found to be maximum at seventh and eighth week P.i. in artificially infected group (++++) and eighth week p.i. in naturally infected group (****).ThesisItem Open Access Studies On Some Aspects Of Experimental Infection Of Toxocara canis LARVAE In ALBINO MICE(Birsa Agricultural University, Ranchi, 1988) Samanta Subhamoy; M. Z. AnsariStudies on the prevalence of Toxocara canis in dogs in and around Ranchi, on the basis of faecal examination revealed that of 197 faecal samples 42 (21.32 were positive for infection. The infection rate was higher 38.03 % (27 of 71) in 'stray dogs than 11.91 % (15 of 126) in 'owved dogs. In both stray' and 'omned' groups of dogs the infection rate was higher in young dogs of less than 1 year (1) age (47.17 % and 24.49 %) and lower in those above 1 year (1) age (11.11 % and 3.89 %) , respectively. On sacrifice of T. canis positive pups, the mean vorm burden vas 10.4 worms/pup and the ratio between male and female worms was almost equal (1.08 : 1). Temperature had profound effect on the embryo nation of T. canes eggs. Eggs kept in cultures reached the infective stage in 32-39 days at 17°C and 12 - 14 days at 27°c. Egg cultures maintained at 37°c disintegrated before reaching the infective stage. The average measurement of unembryonated eggs vas 86.2 by 75.6 , embryonated eggs 86.7 by 77.7 and second stage larvae, recovered from visceral organs, 352.8 by 20.3. Larval recoveries were maximum of 76.8 % in liver on day 2, 22.4 % in lungs and 11.1 % in kidney on day 5, 3.7 % in spleen and 2.7 % in eye on day 10, 57.3 % in skeletal muscles on day 15 and 40.1 % in brain on day 30 post-infection.ThesisItem Open Access Incidence OF Infection in Domestic Animals And Its Control In Mice And Buffaloes(Birsa Agricultural University, Ranchi, 1988) Laha, Ramgopal; K.D PrasadThe present investigation was conducted on "Incidence of Trypanosoma evansi infection in domestic animals and its control in mice and buffaloes to know the status of the protozoa in cattle, buffaloes and goats in and around Ranchi by blood and spleen smears examination alongwith biological test. For developing an effective chemotherapeutic and prophylactic control against the infection in aice and buffaloes, TRIBEXIN Prosalt (IDPL, Hyderabad) was tried in a single S/C dose a 6,66 mg/kg but. The effectiveness of the drug was evaluated on the basis of criteria taken into account. The overall incidence of evansi in cattle and buffaloes revealed 22 (3.17 %) cattle and 12 (2.69 %) buffaloes out of 693 and 446 animals tested, respectively were harboring the organism during the year of examination. But the seasonal incidence of the infection indicated that 4.32, 4.29 and 0.76 per cent cattle were positive for the protozoa during summer, rainy and winter seasons, respectively. The infection rate in buffaloes during summer, rainy and winter seasons were 3.30, 4.29 and 0.61 per cent, respectively. None of the goats tested were found carrier of the protozoa. When the infected mice were therapeutically treated with the drug it cured the mice from the acute infection within 24 hours PF whereas the pretreated mice did not allow the parasites to establish in thes. Further observations showed that the infected mice regained the normal values of DLC, Hb and PCV shortly after treatment. But the treated and subsequentlyThesisItem Open Access Studies On the Immunity Against In Rabbit(Birsa Agricultural University, Ranchi, 1988) Das Abhijit; A. BasuFrom the results of the various experiments of the present study, it can be concluded that the rabbits can be used as a suitable laboratory host for performing various experiments with the tick microplus. By repeated infestation the laboratory host, rabbits gains sufficient amount of resistance against further infestation with B. microplus. For this purpose four repeated infestation is sufficient. As a result of repeated infestation the rabbits attains cell mediated immunity against the ticks evidenced by increase in basophil count. Rabbits can also be immunized by inoculating tick tissus antigon, and this is more effective than immunization by repeated infestation. Inoculation of tick tissues antigen hyper sensitizes the rabbits against the ticks.ThesisItem Open Access STUDIES ON THE INCIDENCE AND HOST-PARASITE RELATIONSHIP OF HYDATID DISEASE IN RUMINANTS(Birsa Agricultural University, 1988) Ghorui, Samar kumar; Sahai, B.N.A total of 1626 animals comprising of cattle (462), buffaloes (312), sheep (79) and goats (773), were examined based on slaughter house and post-mortem room materials for hydatid infection for a period of 13 months (November 87 to November ¹88). The overall infection was 14.32 per cent, whereas host-wise it was 19.70 per cent in cattle, 14.42 per cent in buffaloes, 17.72 per cent in sheep and 10.74 per cent in goats. The statistical analysis for incidence of hydatid infection revealed highly significant P 0.05) . Organ-vise distribution of hydatid infection in various hosts revealed that liver of cattle had highest incidence (45.05 %) followed by lungs (40.66 %), in both lungs and liver (10.99 %) and spleen (3.30 %). In buffaloes, on the other hand, lungs had highest incidence (46.67%) , followed by liver (31.11%), both lung and liver (20.00 %) and spleen (2.22 %). Again, inThesisItem Open Access STUDIES ON INCIDENCE, BIOLOGY AND CONTROL OF TICKS OF BOVINE OF CHOTANAGPUR AND SANTHAL PARGANA(Birsa Agricultural University, 1987) KUMAR, ASHOK; Ansari, M.Z.The thesis embodies the results of investigations on the incidence and intensity of tick infestation in cattle and buffaloes in seven districts of Chotenagpur and senthalPargana of Bihar, biology with particular reference to the effect of temperature and humidity on different developmental stages associated with life cycle of most commonly available species of ticks, oophiluspicroplus and Hyaloage (H) A. anetolicua and control of .nioroplus with two synthetic pyrethroido, cypermethrin and fenvalerate; also the level of serum acetylcholinesterase (che) in the tick-infested and pyrethroid-trosted groups of cow calves and buffolo calves, Studies on incidence revealed that out of 18,613 bead of cattle and buffaloes examined, 2,726 (14.645) were found tick infested. Statistically, the incidence was found to be highly significant (P < 0.01) between cattle and buffaloes, the values being 15.277% and 10.998%, respectively. The date between different age groups; young and adult, revealed highly significant variation in cow calves and adult cattle, but non-significant between cattle calves and buffalo calvos. Breed-wise incidence was found to be significantly higher (17.035%) in cross-breds, as compared to indigenous cattle (13.641 %).ThesisItem Open Access Studies on Sarcoptic mange in Goats and Sheep and its control(Birsa Agricultural University, 1985) Ahmad, Mohammad Aijiaz; Basu, A.Three recent synthetic pyrethroid compounds viz., Butox, sumitik and Taktie were tried at 0.1, 0.2 and 0.5 percent concentrations against the disease in both species of animals. It was observed, that all the three drug when applied at 0.1 and 0.2 per cent concentrations, applied five times at three days interval were not successful to eliminate the mites either in goats or sheep. However, all above drugs were effective against these mites, both in goats and sheep at 0.5 per cent concentration, when applied five times at three days interval. It was concluded that Taktia, 0.5 per cunt was highly effective in goats followed by Butox 0.5 per cent and sumitik 0.5 per cent, in respect of their performance. In sheep, all the three drugs were equally effective at 0.5 per cent concentration when applied 4 or 5 times at three days interval.
