Aim: Ring worm are fungal infection relevant to animal and human health. The study was aimed to assess the frequency of dermatophytes infection of the skin of dogs in and around the Jaipur city. Materials and methods: One twenty canine samples were obtained during three years (2008)(2009)(2010)(2011) from dogs suffering from different dermatological disorders and were invitro processed for dermatophytes detection at the Department of Microbiology, Apollo College of veterinary medicine Agra Road, Jaipur. Result: Out of these, eighty nine samples were positive respectively for Microsporum gypseum 55.83%, Trichophyton mentagrophytes 18.3% and other fungal isolate Alternaria spp. sporadic in 15 samples (0.12%). Retrospective studies of dermatophytosis due to Microsporum and Trichophyton were performed with the sole consideration of public health consequence of the canine ringworm. Conclusion: In the present study samples were found positive for Microsporum gypseum 55.83%, Trichophyton mentagrophytes 18.3% and other fungal isolate Alternaria spp. Considering the veterinary and public health importance of canine ringworm it would be necessary to assess the prevalence of the dermatophytosis in Rajasthan.

Twelve antibiotic-sensitive strains of Arizona and ten of Salmonella were tested for ability to receive drug resistance in vitro from two multiple resistant, R factor-carrying strains of E. coli isolated from soiled eggs. Eleven of the 12 Arizona strains and 8 of the 10 Salmonella strains received the R factor from at least one of the donor E. coli strains. One of the donor strains transferred only part of its drug resistance pattern to some of the sensitive strains. ABSTRACTChicks were hatched from S.C.W.L. hens fed either a control ration or one supplemented with 1333 p.p.m. ascorbic acid. Chicks from each maternal ration were allotted to either a control ration or one supplemented with S00 p.p.m. ascorbic acid. Plasma total and free cholesterol were determined on blood obtained from 1, 7, 14 and 21 day-old chicks on each treatment. Day-old chicks from hens fed ascorbic acid had significantly higher (P < 0.01) plasma total and free cholesterol than did the controls. Plasma cholesterol levels decreased rapidly after hatching and plateaued at about 14 days of age in chicks from all treatments. Ascorbic acid supplementation did not significantly alter hatching or subsequent chick weight.
