The study was aimed to detect virulence associated genes of Salmonella serovars, which were isolated from raw pork samples of unorganised butcher shops of Aizawl and Imphal. A total of 5 Salmonella isolates (Aizawl=2, Imphal=3), belonging to Salmonella vircho (n=4), and Salmonella typhimurium (n=1), were obtained from 200 samples (100= Aizawl and 100= Imphal) and screened for five virulence associated genes, namely invA, stn, pefA, sefC, spvC by Polymerase Chain Reaction (PCR) technique. All Salmonella serovars detected positive for invA and stn genes, spvC and pefA gene was found positive in Salmonella typhimurium and one Salmonella Vircho of Aizawl origin (overall 40%). sefA was absent in all isolates. All the Salmonella serovars possessed invasive gene (invA) and enterotoxin gene (stn), which make them capable for producing gastroenteritis in human. Presence of Salmonella typhimurium positive with 4 virulence associated genes in Aizawl is a matter of worry from hygienic point of view.
