ABSTRACT

Antibiotic resistance represent a very big problem especially those microorganisms exhibit multidrug resistance (MDR) . The aim of this study was to investigate the prevalence of MDR Staphylococcus haemolyticus isolates among infants which is a striking phenomenon on these days . Among 1560 blood cultures , 67 isolates (4.3%) during 2013 were obtained . Only one isolate was sensitive to all antibiotics (19-21) in use in hospital specialized for infants , the rest (95.7%) were MDR . The highest resistance recorded to Erythromycin as 56 isolates out of 67 (83.6 %) , which appeared to be due to mechanisms other than methylation . Resistance to other antibiotics recorded for Gentamicin and Tetracycline . However , all the isolates were sensitive to Tigecycline , Nitrofurantion , Vancomycin , large number of isolates were sensitive to many of antibiotics in use , which reduces the effect of the problem and gave a chance for antibiotics use on these days .
