Abstract

Nosocomial infections are caused for great number of mortality and morbidity. Contamination may result from healthcare workers’ hands or by direct patient's shedding of bacteria which are able to survive up to several months on dry surfaces. The diagram of stethoscope may play significant role in bacteria colonization and transmission form the patient to patient Objective: To isolated and identified bacterial contamination of stethoscope used by health care workers.Materials and Methods: Carried the study between (September - October) 2022, at Zawia Medical Center, 50 swabs were obtained from surface of diagram of stethoscope; the positive isolates were identified according to the standard microbiological techniques.Result: The 28 (56%) sample were contaminated by potential pathogens, 14 (28%) were Non-hemolytic staphylococci, 9 (18%) were Staphylococcus hemolytic, 2 (4%) were Klebsiella spp, 3 (6%) were non-lactose fermenters, which are serious enteric pathogens. Conclusion: The samples taken from the stethoscope were contamination with highly pathogenic bacteria may lead to prevalence the nosocomial infections. Therefore, we recommend to usingdisinfected agent after each examination with stethoscope.
