چکیده
Cockroaches are considered as a serious health problem in some medical centers. They can move freely in hospital wards and transmit pathogenic organisms. This study was done for detection and identification of bacterial infection in outer surface and digestive organ of Blatella germanica as a dominant cockroach species in hospitals. In this cross-sectional study 222 B.germanica collected from 14 different wards of 5 hospitals of Hamedan county, west of Iran. Most of them were collected from Kitchenself- service (34.2%), followed by urology ward (13.5%). After anesthesia and washing in 2cc physiology serum, the culture was prepared from this suspension for identification of bacterial infection on outer surface. After sterilization of outer surface of each cockroach, their guts have been isolated from mouth to anus and bacteria extraction and culture was done as the same. Totally,12 bacteria species identified from outer surface and digestive system of cockroaches. In outer surface, Escherichia coli was the most dominant species (40%) followed by Staphylococcus epidermidis (20%). In digestive system E.coli had also the most percent (45%) followed by Entrobacter aeroginosa (20%). This study can show the importance of cockroaches as potential vectors of medically important microorganisms such as pathogenic bacteria in hospitals. The control programs for remove cockroaches especially in the hospitals is suggested.
