Resistance to β- lactams and detection of plasmid-Encoded CMY-2 Like Cephalosporinase from human and veterinary Salmonella isolates

الملخص EN

Thirty two Salmonella serovar were isolated from human, animal (dairy cows and calves) and environment in Suez Canal area and tested for their antibiotic resistance.

The prevalence of multiple antibiotics resistance was high especially to β-lactams antibiotics.

Plasmid profile showed 19 (59.4 %) of the total 32 isolates had one or more plasmid ranging from 1.2 to 5.2 Kbp.

Detection of bla TEM and blaCMY-2 like β-lactamase mediated plasmid, by PCR all 19 serovar were positive generated a single 1.1 Kb amplified DNA fragment, on 1 % agarose gel.
