Field strains of Salmonella enterica sub species enterica biovar Gallinarum (Salmonella Gallinarum-SG) were tested for R-factor mediated conjugative tansfer of drug resistance, bacteriocinogeny and serum resistance to a recipient E. coli (K12 F-Lac+Nal) strain. Out of 15 strains of SG, 6 (40%) transferred enbloc resistance against tetracycline, gentamicin as well as sulfamethoxazole (TGS) and 5 (33.3%) transferred enbloc resistance against GS while 4 (26.6%) failed to transfer drug resistance. Ten strains were investigated for transfer of bacteriocinogeny, 7 (70%) could transfer bacteriocinogeny to the recipient strain, while none out of 8 strains could transfer resistance against bacteriolytic activity of guinea pig and chicken serum. The possible implications of these fators in the treatment and pathogenesis of Salmonella Gallinarum infections has been discussed.
