study of Teicoplanin resistant among clinical Staphylococcus and Enterococcus isolated

Abstract

The Gram positive cocci, Staphylococcus aureus and Enterococcus are the bacteria most often asolate from patients with hospital acquired infection . s.aureus is one of the most important pathogens and variety of varulance mechanisms which help it to infect the patient and cause tissue damage , while Enterococcus lest virulent .forty five asolates Enterococcus spp and fifty isolate Staphylococcus were collected from clinical samples included blood,urine from different Baghdad hospitals. Result of revealed that the sensitivity of isolates to Teicoplanin was tested, and results showed that all the isolates to Staphylococcus spp was sensitive to Teicoplanin ,while (45) of isolate Enterococcus spp were (26.7%) resistant to Teicoplanin .results of DNA extraction from Teicoplanin resistant isolates, showed that (5) isolates have one plasmid band.
