چکیده
conclusions vancomycin, but not teicoplanin, can be considered an effective antibiotic of choice for controlling infections caused by mdr cons in gorgan, depending on the bacterial species. background coagulase-negative staphylococci (cons) are clinically important, especially in nosocomial and neonatal infections. the increasing emergence of glycopeptide-resistant cons has made these agents therapeutically challenging. objectives we aimed to investigate the susceptibility patterns of cons to teicoplanin and vancomycin in gorgan, northern iran. materials and methods a total of 100 clinical samples were obtained from different wards of a hospital and screened for cons with standard microbiological and biochemical tests. antibiogram testing was carried out for the detection of vancomycin-, teicoplanin-, and multidrug-resistant (mdr) species. the minimum inhibitory concentration (mic) of vancomycin was determined using e-test strips. the presence of the vana gene was investigated with pcr. results only 1% of cons (staphylococcus haominis) showed resistance to vancomycin and 15% of these were intermediate-resistant to teicoplanin on the disc diffusion agar test. in addition, all isolates (100%) were negative for vana on pcr and sensitive with e-test methods. the mean mic value of vancomycin was 1.35 ± 0.29 µg/ml. s. haemolyticus and s. epidermidis showed the highest rates of mdr (50% and 24%, respectively). additionally, cons isolated from blood (42%) and urine samples (30%) had the highest rates of mdr.
