Transstadial and horizontal transfer of bacteria within a colony of Anopheles gambiae (Diptera: Culicidae) and oviposition response to bacteria-containing water

The tsetse fly Glossina fuscipes fuscipes (Diptera: Glossina) harbours a surprising diversity of bacteria other than symbionts

“…Given that adult mosquitoes feed on various sugar sources in the field in addition to blood this seems improbable. Furthermore, larval mosquitoes live in water bodies with high loads of bacteria and the adults are capable of ingesting bacteria from that water after they emerge (Lindh et al 2008). However, mosquitoes and tsetse flies have a different mode of blood-feeding and this may account for the differences seen.…”

Mosquito/microbiota interactions: from complex relationships to biotechnological perspectives

“…Two recently described species associated with the midgut of An. gambiae, are Pantoea stewartii and Elizabethkingia meningoseptica [46]. A new isolate from An.…”

Bacterial Biodiversity in Midguts of Anopheles Mosquitoes, Malaria Vectors in Southeast Asia

“…The first of the three species represents a new genus and species found predominant in the midgut of Anopheles arabiensis [29], the same Anopheles species in which J. anophelis was isolated. The third newly described species is closely related to Elizabethkingia meningoseptica as they share 98.6% similarity, and both species have been found in the midgut of Anopheles gambiae [11,28]. The latter species, E. meningoseptica, was also isolated from diseased birds, frogs, turtles, cats, being most likely an agent of zoonotic infections, as well as a human meningitis especially in newborn infants [30].…”

“…Recent studies showed that one of these factors concerns the primordial role played by the bacteria naturally present in mosquito midgut. Then, there is a growing interest on bacterial biodiversity in Anopheles mosquitoes and particularly those based on the identification of bacteria to be used for malaria transmission blocking based on bacterial genetic changes to deliver antiparasite molecules or paratransgenic approach [5][6][7][8][9][10][11][12][13]. Recent studies reported the presence of symbiotic bacteria, such as Pantoea agglomerans or Asaia in midgut lumen with anti-Plasmodium effector proteins that render host mosquitoes refractory to malaria infection [6,10,13].…”
