Abstract
The common fly (Musca domestica L.) is a mechanical vector and can be a biological vector through ingestion and regurgitation. In rural communities is common to observe numerous populations of this, consequence of multiple unsanitary sites. The present study was carried out in order to identify the species of bacteria and parasites with medical importance present in the common fly, captured in homes and microhabitats (chicken coops, pigsty and backyards) in homes of the community of Cholul, Cantamayec. 20 species of bacteria were identified: E. coli (41.78%) was the most frequent species in all processed flies. In turn, households (45.20%) were the place where the greatest amount of bacterial species was isolated, being E. coli (42.42%), the frequent species, in the same way in pigsty (45.65%), chicken coops (38.09%) and backyards (30.76%). Regarding the enteroparasites identified from the digestive cavity of flies, Endolimax nana (38.46%) was the frequent cyst and Ascaris lumbricoides (15.38%), the only nematode found. In turn, the pigsty (n = 5) was the site with the highest number of isolated enteroparasites. The results obtained show that flies carry pathogens that could be involved in human infections ofcommunity origin.
