ALVES, Willy Cristiano Luz; GORAYEB, Inocêncio de Sousa  e  LOUREIRO, Edvaldo Carlos Brito. Isolated bacteria from hematophagous Culicidae (Diptera: Nematocera) in Belém, Pará State, Brazil. Rev Pan-Amaz Saude [online]. 2010, vol.1, n.1, pp.131-142. ISSN 2176-6223.  http://dx.doi.org/10.5123/S2176-62232010000100019.

Bacteria are largely distributed in nature, especially when carried by a vector. They comprise large portions of the human and animal microbiota, and some cause diseases. The diptera of the family Culicidae are directly involved in the vectoring of epidemics of great interest for public health. However, the association between bacteria and Culicidae has been scarcely studied. In order to deepen the knowledge on this subject, we isolated and identified bacteria which have been transported in hematophagous Culicidae in the City of Belém, Pará State. The collection of 296 mosquitoes was carried out using a CDC light trap in eight collection localities, which presented different environmental characteristics within the metropolitan area of Belém. Some were identified to the species level (9) and others to the subgenus (4). It was possible to identify 17 species of bacteria; seven bacteria could only be identified up to their genus. Culex quinquefasciatus and Anopheles aquasalis were the most frequent Culicidae. The most frequent species of bacteria found in the samples were Gemella haemolysans and Enterobacter cloacae. The collection localities in the Terra-firme and Curió-utinga districts presented the largest diversity of species of Culicidae.
