Resumo em Inglês
Phlebotomine sand flies are vectors of Leishmania that are acquired by the female sand fly during blood feeding on an
infected mammal. Leishmania parasites develop exclusively in the gut lumen during their residence in the insect before
transmission to a suitable host during the next blood feed. Female phlebotomine sand flies are blood feeding insects but
their life style of visiting plants as well as animals, and the propensity for larvae to feed on detritus including animal faeces
means that the insect host and parasite are exposed to a range of microorganisms. Thus, the sand fly microbiota may
interact with the developing Leishmania population in the gut. The aim of the study was to investigate and identify the
bacterial diversity associated with wild adult female Lutzomyia sand flies from different geographical locations in the New
World. The bacterial phylotypes recovered from 16S rRNA gene clone libraries obtained from wild caught adult female
Lutzomyia sand flies were estimated from direct band sequencing after denaturing gradient gel electrophoresis of bacterial
16 rRNA gene fragments. These results confirm that the Lutzomyia sand flies contain a limited array of bacterial phylotypes
across several divisions. Several potential plant-related bacterial sequences were detected including Erwinia sp. and putative
Ralstonia sp. from two sand fly species sampled from 3 geographically separated regions in Brazil. Identification of putative
human pathogens also demonstrated the potential for sand flies to act as vectors of bacterial pathogens of medical
importance in addition to their role in Leishmania transmission.
