title: INVESTIGATION OF BACTERIOLOGICAL INFECTIONS OF THE AMERICAN COCKROACHES IN PAVEH CITY, KERMANSHAH PROVINCE.
abstract: BACKGROUND
  American cockroaches, Periplaneta americana, are the most important pests in hospitals and dwelling environments. They are mechanical vectors of some bacterial pathogens.
  
  
  OBJECTIVE
  The present investigation was carried out in Ghods hospital and 5 dwelling localities of Paveh city to evaluate bacterial infestations of American cockroaches in this region of Iran.
  
  
  METHODS
  The samples were randomly collected from hospital environments and toilets and kitchens of the dwelling localities from December-March 2012 and July-September 2013. The samples were captured using sterile test tubes and sterile hand gloves.
  
  
  RESULTS
  Totally, 98 cockroaches were collected from hospital (45.9%) and dwelling (54.1%) environments. Eight groups of bacteria including: Pseudomonas spp., Proteus spp., Klebsiella spp., Staphylococcus spp., Bacillus spp., Serratia spp., Entrobacter spp. and Escherichia coli were extracted.
  
  
  CONCLUSIONS
  The findings of the present study revealed that the American cockroaches are very important in transmission of some bacterial pathogens, so health education and using the effective control methods to elimination and reduction of cockroaches are necessary.
