[Digestive tract microbiota in female Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera: Psychodidae) from colonies feeding on blood meal and sucrose plus blood meal].
There are very few reports on the microbiota of the digestive tract of sand flies, an important omission considering that blood is not the only meal ingested. Male and female sand flies obtain sugar meals from several sources, thereby increasing their chance of infection with microorganisms. Chances of contamination are higher when insects are bred in the laboratory, and this may affect the development of Leishmania spp. From the digestive tract of 300 sand fly females separated in two groups we isolated 10 species of bacteria in group 1 and 8 species in group 2. In group 1, Enterobacteriaceae of the following genera were identified: Serratia, Enterobacter, and Yokenella and the non-fermenters: Pseudomonas, Acinetobacter, and Stenotrophomonas. In group 2, the Enterobacteriaceae Enterobacter and Serratia were identified as well as the non-fermenters Acinetobacter, Stenotrophomonas, Burkolderia, and Pseudomonas.
