The study was conducted to determine the virulence associated genes and antimicrobial resistance of S. suis associated with various disease conditions of pigs. The VAGs mrp and arcA were present in 79.41% (each) of the isolates whereas sly gene was carried by 64.70% isolates. mrp⁺ + sly⁺ + arcA⁺ , mrp⁺ + sly⁺ , mrp⁺ + arcA⁺ and sly⁺ + arcA⁺ genes were carried by 23.52%, 20.58%, 35.29% and 20.58% isolates respectively. All isolates were negative for epf gene. Interestingly all the invasive strains carried sly genes whereas only 25% strains from cases of pneumonia carried this gene. The most effective antimicrobial against S. suis was ampicillin (85.29%) and the isolates showed high frequency of resistance to tetracycline (82.35%). The occurrence of relatively high levels of resistance of S. suis to some antimicrobials (e.g. macrolides, tetracyclines, and sulphonamides) as observed in the present study may represent a human health concern.
