Salmonella, Beta-lalctamaz, Ampicillin


Resistance to chloramphenicol and ampicillin, first choice drugs in the treatment of salmonellosis, has been increasing day to day. This resistance generally depends on plasmid mediated beta-lactamase activity.

The ease of plasmid tranfering plays an important role in the spread of antibiotic resistance from one bacterial strain to another.

In this study, beta-lactamase activity and the resistance of ampicillin in totally 97 salmonella strains isolated from stool and blood specimens were investigated. Beta-Jactamase activity was detected in 38 of these bacteria. Except for a beta-lactamase positive strain of S.schottmuelleri, the resistance of ampicillin was detected in all salmonella strains having beta-lactamase enzyme.
