    Survey on Prevalence of Brucella Infection in Sheep and Goats
    (Karnataka Veterinary, Animal and Fisheries Sciences University , Bidar, 2011-06-17) Nethra, R.; Ramesh, P.T.; Uppendra, H. A.; Ansar Kamaran, C.; Narayanswamy, H.D.; Rathnamma, D.; --, --
    The present study was carried out in six different farms of sheep and goats i.e., at Bengaluru, Haniyuru, Allipura, Huduguru, Veerapsandra and Peddaenhalli to survey on seroprevalence of brucella infection by RBPT and STAT. Preliminary screening of a total of 148 sheep and 104 goat sera samples in six farms by RBPT revealed 10 (6.7%) sheep and 7 (7%) goats as reactors. All the RBPT reactors were further subjected to standard tube agglutination test. All the animals selected in farms at Bengaluru and Haniyuru were seronegative which could be hypothesized that animals were not exposed to the infectious agent. So, the seroprevalence recorded were 7%, 14.3%, 3.3% and 2.85% at Allipura, Huduguru, Veerapsandra and Peddaenhalli respectively which might be due to endemicity. Identification of endemic areas would be helpful in culling the seropositive animals and undertaking vaccination program. In the hematological and biochemical analysis conducted, there was significantly higher (P<0.05) TLC values and neutrophil count, significantly lower hemoglobin levels, lymphocyte and monocyte count and no significant variation in PCV of blood samples in brucella seropositive animals. This might be due to cellular immune response to bacterial infection and anemia due to brucella’s tropism to reticuloendothelial system. There was no significant variation (P<0.05) in AST & GGT and albumin: globulin ratio values in brucella seropositive animals and hence no damage to liver was observed in the present study conducted. The present study revealed 15 Km distance between each farm, communal pasturing and watering, comingling of the animals, open system of rearing and non utilization of immunization are the risk factors in seropositive farms which declared the minimal epidemiological unit of intervention.

    Studies on Cryptococcosis in Ruminants, Equines and Birds
    (Karnataka Veterinary, Animal and Fisheries Sciences University , Bidar, 2011-09-22) Bawane, Pradip Vishwanath; Ramesh, P.T.; Ansar Kamaran, C.; Narayana Bhat, M; Narayana Swamy, M.; Ranganath, L.; --, --
    In the study of Cryptococcosis in ruminants, equine and birds, a total of 290 fecal samples in which cattle (25), sheep (25), goats (30), and horses (30) fecal samples were collected from the without clinical signs of Cryptococcosis. From birds a total of 180 fecal samples were collected and they were: Fifty from Cockteil (dry and 25 fresh), 30 from Munia (15 dry and 15 wet) 30 from Pigeon (15 dry and 15 wet), 30 from Hornbill (15 dry and 15 fresh) and pheasant (40) in which (20 dry and 20 wet). After processing all the samples, 0.1 ml and 0.2 ml aliquot of the processed samples were streaked on the three media viz., sunflower seed agar media, malt agar media and Sabouraud dextrose agar media. All the inoculated plates were observed for the development of dark brown pigmentation of Cryptococcus for the next 9 to 10 days. Out of 180 fecal samples of birds processed, 23 (8%) samples were positive for the growth of Cryptococcus and showed positive urease test, growth at 37 ºC, phenoloxidase activity but failed for KNO3 utilization. The overall prevalence of Cryptococcus reported was 8% in ruminants, equines and birds while overall prevalence of Cryptococcosis in birds reported was 12.77%. in which, in cockteil 12 samples were positive including the eight dry fecal sample and four wet, from eight positive pigeon samples two were from dry samples and six from wet, three isolates from the pheasant birds showed the positive growth for Cryptococcus in which two samples were from dry fecal samples and one was wet while none of cultured plates inoculated with fecal samples of cattle, sheep and goat and equine were positive. It was concluded that sunflower seed agar is excellent media for growth of yeast Cryptococcus and dry fecal sample is good source of Cryptococcus.
