abstract
The study aimed to detect Salmonella by cultural and molecular methods, its serotyping and antimicrobial sensitivity pattern in different samples of chicken sources from Mizoram. A total of 400 samples comprised of raw meat (50), internal organs (50), egg (50) and cloacal swab (50), each from Aizawl and Kolasib district were subjected to isolation and identification of Salmonella by conventional bacteriological methods which involved pre enrichment, enrichment, selective plating on agar media and biochemical tests. The presumptive Salmonella isolates were subjected to16S-rRNA gene detection and subsequently to serotyping and antimicrobial sensitivity test. A total of 27 (6.75%) Salmonella typhimurium serovars were confirmed by PCR and serotyping. Highest numbers of Salmonella were recovered in XLD agar with PCR conformity. Salmonella typhimurium was detected highest in internal organs followed by cloacal swab, egg and meat. The serovars showed 100 per cent sensitivity towards Imipenem and highest resistance to Tetracycline (92.59%).
