BEJAR C, Vilma et al. Musca domestica como vector mecánico de bacterias enteropatógenas en mercados y basurales de Lima y Callao. Rev. perú. med. exp. salud publica [online]. 2006, vol.23, n.1, pp. 39-43. ISSN 1726-4634.
Objectives: To prove that domestic fly (Musca domestica) is a mechanic vector for enteropathogenic bacteria in Lima and Callao districts. Materials and methods: Cross sectional descriptive study. Between May 2004 and July 2005 a sampling was performed in different districts in Lima and Callao, considering the infestation index in each selected area. Flies from markets, peripheral areas and surrounding junkyards were collected. The insects were later processed in the laboratory for isolation and identification of enterobacteria. Results: Out of 780 flies, enteropathogenic Escherichia coli, Salmonella typhi, Shigella flexneri, and Yersinia enterocolitica were isolated. A direct relationship between finding enteropathogenic bacteria and the areas with greatest infestation indexes (20 flies/hour in observation). Conclusion: The isolation of enteropathogenic bacteria in Musca domestica allowed us to prove its role as a vector.
