Assessing the prevalence of Gram Negative Bacilli Isolated from Hospitals\' Equipment and Surfaces in Western Region of Golestan province

Background:Nosocomial infections due to mortality and economic costs are one of the main challenges in current century. Gram-negative bacilli infections acquired in hospitals and hospital environment is one of the most important places of residence and publication of these types of bacteria.
