                    Background and Objectives: Reference to the role of cockroaches in transporting and 
distributing of various disease agents in remedial and hospital environment, dwellings 
and  dormitories,  the  present  study  aimed  to  study  the  fauna  of  bacteria  and  fungi 
associated  with  the  digestive  system  of  Blattela  germanica L.  collected  from  various 
locations at the end of fall in Mashhad. 
Materials and Methods: After dissection of digestive system under sterile condition,
the  extractions  were  incubated  in  EMB  and  Blood  Agar  medium.  Bacteria  and  fungi 
were identified by clinic of microbiology of Imam Reza hospital of Mashhad. 
Results:  The  most  prevalent  bacteria  in  hospital  were  Enterococcus spp.  (78%)  and 
Entrobacter aerogenes (50%). The most prevalent bacteria in dwellings wereKlebsiella
oxytoca(80%) and Enterococcusspp. (66%). The most prevalent bacteria in dormitories 
were Entrobacter aerogenes (96%) and Enterococcusspp.  (50%). The fauna of bacteria 
in  hospital  consisted  of  Enterococcus spp.,  Coagulase  Negative  Staphylococci, 
Staphylococcus aureus, Streptococcus  spp. andEscherichia coli. The fauna of bacteria 
associated  with  dwellings  consisted  of  Enterococcus spp.,  Staphylococcus  spp., 
Klebsiella spp.,  Entrobacter  aerogenes and Micrococcus spp.,  whereas  all  species 
except Micrococcusspp. were found in dormitories. Moreover two species including P. 
vulgaris  and P.  mirabilis were  found  in  dormitories  just.  The  results  indicated  that  3 
fungi  were  observed  in  the  digestive  system  of  cockroaches  collected  in  all  three 
locations. 
Conclusions: The results suggested that for reducing the risk of transmission of various 
disease agents, suitable control measures should be applied to manage the population of 
cockroaches in various locations.
