    Bacteriological Quality of Pork and pork product with special reference to Enterotoxigenic
    (Birsa Agricultural University, Ranchi, 1992) Mohammad Kalimuddin; S.P.Choudhary
    It was also concluded that while studying enteropathogenicity/enterotoxigenicity of the isolates of Salmonella, consideration of the results of histopathological changes in the Intestinal loops of animal model is also essential atleast for those loops showing dilstation index less than 0.40.

    Biotyping and Serotyping of Bacillus Cereus Isolated from fried Rice and Chawmin
    (Birsa Agricultural University, Ranchi, 1993) Rajendra Yadav; K.G.Narayan
    Bacillus cercus has recently emerged as one of the most important food borne pathogen in India. It is most commonly associated with cereal foods causing diarrhea and vomition in human being. As compared to other food borne pathogens relatively little work has been done on . cercus particularly with fast foods. Therefore, the present investigation was undertaken to see the incidence of this organism in chawmin and fried rice. Skimmed milk powder was also included in this study. Altogether 226 samples consisting of chowmin (100), fried rice (100) and skimmed milk powder (26) were examined. The result has been presented in log10 scale. Altogether 23.0, 24.0 and 69.23 per cent of the samples of chaumin, fried rice and skimmed milk powder were positive for cereus and the counts ranged between zero to 3.9193/0, zero to 3.6182/g and zero to 3.6812/g with an average of 0.6453 0.1225, 0.7394 0.1400 and 1.9386 0.2736/s, respectively. Mannitol egg yolk polymixin agar appears to be a satisfactory selective and differential medium for cereus which is inhibitory to many bacteria and only a limited group of organisms grew on it. Viz. S. aureus, Serratia marcescens and P. vulgaris. The number of such bacteria was also estimated and designated as bacteria other than cercus. Altogether 74.0, 64.0 and zero per cent of the samples of choumin, fried rice and skimmed milk powder were positive for bacteria other than cercus and the count ranged from zero to 5.4771, zero

    Rabies Infection and protection in Pubs less than 10- 12 weeks
    (Birsa Agricultural University, Ranchi, 1991) Anjan Bhattacharya; K.G.Narayan
    Ninety nine apparently healthy street pups of 10-12 weeks of age were found to be free from rabies virus. This is based on simultaneous examination of brain, salivary gland and tonsil of each of 99 pups. The results of examining the above 297 samples simultaneously by 5 different tests vis., MIT, FAT, IPT, DOT-ELISA and Seller's stain add strength in declaring that the 99 pups examined were negative for rabies. Serologic tests like FAT and IPT were comparable to MIT as was earlier reported by Department of Veterinary Public Health & Epidemiology. In addition ELISA and DOT-ELISA tests were carried out. The former, reported from Pasteur Institute, Paris was found to be equally comparable. DOT-ELISA was developed in order to make rabies diagnosis easy. Results of ELISA and DOT-ELISA compared with MIT suggested that it was possible to titrate rabies virus antigen. Serum neutralization test in mice carried out in this study was comparable to those being routinely done at Central Research Institute, Kasauli. The three testa, viz., SN, ELISA and DOT-ELISA were used to monitor the response of vaccination of pups 4 weeks old with Raksharab and Rabisin. The of the three tests were comparable thus indicating that one could determine anti rabic serum titre by ELISA and DOT-ELISA instead of SN.
