Abstract

In this study, we aim to find the presence of virulence-related plasmid in Salmonella isolates from poultry, and the difference between S pullorum and S gallinarum on the plasmid profile and antibiotics resistance. We used seventeen isolates of Salmonella spp that were isolated from poultry. Thirteen isolates, S typhimurium(ST), S pullorum(SP) and S gallinarum(SG), contained virulence-related plasmids. These are 95Kd plasmid in ST and 85Kd plasmid in SP and SG. Three(1/4 of ST, 1/1 of SE, and 1/9 of SP) isolates have no detectable plasmids. The isolates of ST have relatively variable plasmid profile but the isolates of S pullorum except No 12(additional 3.0Kb plasmid) have common 85K6, 8.1Kb, 4.0Kb and 2.3Kb plasmid and two of three isolates of S gallinarum have common 85Kb, 4.0Kb and 2.3Kb plasmid but the rest has only 85Kb plasmid. Interestingly, all of the isolates of SP have 8.1Kb plasmid, and same size of plasmid is also found in one of ST isolates. All of the isolates have the resistance to penicillin, chloramphenicol, rifampicin, streptomycin, sulfamethazine and some isolates show the resistance to ampicillin and tetracycline. There is no relatedness between plasmid profile and antibiotics resistance and no differences between SP and SG in antibiotics resistance. Therefore further differentiation of each isolates by restriction enzyme assay and, if possible, charaterization of each plasmid, especially, 8.1Kb plasmid in SP and ST, may be necessary.
