    Survey on the incidence of Salmonellae in meat animals
    (Department of Microbiology, College of Veterinary and Animal Sciences, Mannuthy, 1977) James, P C; Abdulla, P K
    Prior to this “Survey on the Incidence of Salmonellae in Meat Animals” the information on the serotypes of Salmonella prevalent and the magnitude of their occurrence in livestock in Kerala had been meagre except for the reports by Sulochana et al. (1973) and Balakrishna Pillai (1975). The work carried out during the present investigation has gathered more information on the prevalence of Salmonella in livestock in Kerala. In this study the prevalence of Salmonella serotypes in the different species of animals was probed. A total of 823 biomaterials, besides 50 drain samples were subjected to cultural screening. This venture resulted in the recovery of 56 strains of Salmonella. Serological identification of many of these strains proved the prevalence of S. typhimurium, S. weltevreden and S. urbana. The preponderatingly prevalent serotypes were found to be the former two. Pathogenicity studies employing S. typhimurium culture in mice, guinea pigs, rabbits, calves and piglets were conducted. All these animals were found to be susceptible to infection by S. typhimurium evincing varying degrees of clinical manifestations. The advantages of employing modified McConkey’s medium (Sharma, 1961) containing Mannitol instead of lactose and composite medium 1 and 11 developed by Chitin is et al. (1972) to differentiate Salmonella at primary screening level have been discussed
