Abstract
The aims of this study were to characterize
S. aureus isolates from different meat
sources in Jordan and study their genetic relationship using PCR-RFLP in
addition to their antibiotic resistance profiles. Thirty S. aureus
isolates were identified and confirmed by PCR techniques. The isolates from goat
and camel meats were sensitive to the majority of the tested antibiotics.
Plasmid profiling revealed that 26 isolates contained at least one plasmid with
no correlation between the number of plasmids and the resistance profiles.
PCR-RFLP of the coagulase gene (coa) classified the isolates to several clusters
upon digestion with Alu I or
Cfo I restriction enzymes. This study
concluded that the 30 S. aureus
isolates were genetically diverse and comprised heterogeneous population with 7
genotypes at both 33.1 and 51.2 similarity levels.
