S.aureusis the most common gram positive bacterium causing nosocomial infection.E.coliand K.pneomoniaeis the most common gram negative bacterium, causing mainly urinary tract infections.P.aeruginosais also very common,chiefly causing lower respiratory tract infections.The aim of this search is comparative bacterial spread pattern in blood, urine and skin wounds isolated from nosocomial infections in Iran. Materials and MethodsThe research was laboratory based and performed during 2007-2008 years in Azzahrahospital in Isfahan, According to statistical formulaselected 100 blood, urine and skin wounds, in nosocomial infection.Bacterial identification was performed with microbiological methods.ResultsFrom 100 isolate pathogen Bacteria from nosocomial infection,frequency ofStaphylococcus spp.,Enterobacteriaceae and Pseudomonas sp.in blood infection respectively was 70%, 25% and 5%,in urine infection respectively was 45%, 50%, 5% and in skin wounds infectionwas 35%, 15% and 50% respectively. The result showed high frequency of gram positive coccus and gram negative bacilliinnosocomial infections.Commonreasons of nosocomial infections include:hospitals house large numbers of people who are sick and whose immune systems are often in a weakened state;Increased use of outpatient treatment means that people who are in the hospital are sicker on average;Medical staff move from patient to patient,providing a way for pathogens to spread;Manymedical procedures
