| Abstract | ||
| Two hundred faeces sample were collected from cattle with different age and sex in Al- Diwaniyah Province. The study was conducted in the period between November 2016 and November 2017. Salmonella typhimurium bacteria identified by routine methods such as culturing on selective media, biochemical test and agglutination test using monovalent and multivalent antisera. PCR was can detection type-1 fimbriae gene coding for fimC of Salmonella typhimurium. Results showed that Salmonella isolates were 14.5% in the bovine fecal samples. Also, the serotyping of isolates by using monovalent and polyvalent antisera revealed that all Salmonella isolates in cows were S. typhimurium. The PCR technique was used for detection of type-1 fimbriae coding gene by specific primer for fimC gene. All S. typhimurium isolates in cows appeared to be contained this gene show one distinct band MW.289 bp when electrophoresed on agarose gel. The results of this score indicated that the PCR technique potentate a loud specify in the disclosing of S. typhimurium especially the serotype that encoded to fimC gene type-1 fimbriae isolated from cows in comparison to other routine diagnostic tests. | ||
