Ninety two Salmonella enterica subspecies enterica serovar gallinarum biovar Gallinarum strains of avian origin isilated from Gujarat State were characterized by biotyping, antimicrobial drug resistance, bacteriocin production and serum resistance. Variability in the phenotypic potentials associated with production of H2S in TSI, orinithine decarboxylse activity and ferentation of rhamnose were observed. Antimicrobial sensitivity test revealed multiple drug resistance and choramphenicol was found to be the most effective while sulfamethoxazole was the elast effective drug. Fifteen (16.3%) strains were bacteriocin producers while 10 strains were resistant to bacteriocidal activity of guinea pig and chicken sera. The possible implications of bacteriocin production and serum resistance in th pathognesis of avian salmonellosis have been discussed.
