Rapid and precise diagnosis in natural field cases of bovine abortion warrants use of most sensitive and reliable diagnostic methods. In the present study, histopathological, immuno-histochemical and PCR technique(s) have been applied for diagnosis of abortion cases due to Salmonellosis. Histopathologically, multifocal lymphoid granulomas were observed in liver of aborted fetuse(s) which showed positive immuno-reactivity to the anti-Salmonella polyclonal antibody. PCR for diagnosis of salmonellosis in the aborted bovine fetuses found two positive samples out of the total 113 samples tested. Primers S18/ S19 pair amplified a 159 bp region of the sequence encoding an ompC gene of Salmonella species.
