“…In the same way, the bacteria interfere with the development of promastigotes in the digestive tract of sand fl ies competing for nutrients and reducing the pH (Dillon et al 1996). In nature, despite the probable well-balanced associations between some bacteria and sand fl ies, there should be natural selective pressure involving some species of bacteria, leishmania and their vectors, acting directly over the prevalence of infection by Leishmania spp.…”

Reports on gut microbiota of wild sand fl ies belonging to Phlebotomus showed the presence of S. marcescens, A. baumannii and P. aeruginosa (Dillon et al 1996, Warburg 1991, which were also associated with L. longipalpis.…”

“…Dillon et al (1996) suggested that the fl uctuation of the bacterial species in the gut of P. papatasi increased after blood feeding. Ingestion of the Gram negative bacteria E. coli H243 and S. marcescens by blood feeding blocked the development of the Plasmodium falciparum oocysts (Pumpuni et al 1993 in Anopheles stephensi (Liston).…”

“…Studies demonstrated that E. cloacae is the most common bacteria found in the gut of insects of medical importance or not, including sand fl ies (Rossiter et al 1983, Tanada & Kaya 1993, Dillon et al 1996. In the midgut of mosquitoes collected from the fi eld or maintained in insectary, Enterobacter has no infl uence in the insect's survival.…”

“…DeMaio et al (1996) and Pumpuni et al (1996) reported a frequent presence of Gram-negative rods belonging to Enterobacteriaceae in adults of Culex as well as Anopheles species. In laboratory-reared and wild-caught sandflies all predominant species identified by Dillon et al (1996) belonged to Enterobacteriaceae. The genus Serratia has a wide host range and has been isolated from various insect groups (Krieg 1987).…”

We show for the first time that the ventral diverticulum of the mosquito gut (impermeable sugar storage organ) harbors microorganisms. The gut diverticulum from newly emerged and non-fedAedes aegypti (Diptera: Culicidae, Aedini) is the main urban vector for the human diseases yellow fever and dengue fever (Nasci & Miller 1996). The vector control, mainly by insecticide application and elimination of oviposition sites, has been used as the best solution to decrease the diseases incidence. Explore new strategies for blocking the insect transmitted diseases such as dengue fever is urgent in Tropical countries (Sperança & Capurro 2007). Microorganisms associated with the insect may have an important role for human infectious diseases epidemiology. Once a key role bacterium is discovered, it may be modified in order to affect the pathogen development and, consequently, the disease transmission (Azambuja et al. 2005, Riehle & Jacobs-Lorena 2005.The alimentary canal of the mosquito is composed by the foregut, midgut and hindgut. The foregut is involved primarily with ingestion, conduction and storage of food (Romoser 1996). In the alimentary canal of the mosquito three diverticula arise near the posterior end of the esophagus: two from the dorso-lateral and one from the ventral wall of the gut, all surrounded by a thin impermeable cuticle. The ventral diverticulum (VD), or crop, is large and may extend into the abdomen (Dapples & Lea 1974). Usually all three diverticula are filled with air bubbles and are used as food reservoirs (Thompson 1905, Consoli & Lourenço-de-Oliveira 1994. The sugar meal, such as floral nectar, is stored in the diverticula and passes slowly to the midgut, where it is digested (Thompson 1905).Microorganisms play important and often essential roles in the growth and development of many insect species. Despite the importance of these microbial associations with insects there are relatively few studies that elucidate their components and their roles in the interactions. Insects that rely on nutritionally poor diets tend to possess bacterial endosymbionts. Aphids, for example, which subsist solely on plant sap, harbor Buchnera spp., believed to provide amino acids and vitamins to their hosts (Douglas 1989). Blood is known to be severely deficient in essential B vitamins and some amino acids. Bloodsucking arthropods such as ticks, lice, bedbugs, reduviid bugs, and tsetse flies usually harbor symbiotic microorganisms (Buchner 1965). Symbiotic relationships have already been reported for blood feeding insects and some are very well established, as in the case of Rhodnius prolixus that maintains an association with the actinomycete bacteria Rhodococcus rhodnii (Dasch et al. 1984); and tsetse flies genus Glossina, which harbor three distinct symbiotic microorganisms: Wigglesworthia glossinidia, Sodalis glossinidius (commensal), and the parasitic microbe Wolbachia pipientis (Aksoy et al. 1997, Chen et al. 1999.Many key questions about bacteria within the mosquito's midgut remain largely unanswered, and ob...
