Aedes albopictus
The mosquito species "Anopheles gambiae", which is notorious mainly as a malaria vector, has been demonstrated to be a competent vector for "Rickettsia felis". More unexpectedly, cells of some important disease vector species of mosquitoes in the genus "Aedes", which is most commonly seen as a vector for arboviruses, support growth of "Rickettsia felis". In addition, in tropical regions where "Aedes albopictus" and "Aedes aegypti" are established disease vectors and ectoparasites of humans, patients have tested positive for "Rickettsia felis". To some authorities this suggests that "Aedes" species might be able to infect their hosts with "Rickettsia felis", and that patients in, or returning from, the tropics with fevers of unknown origin, should be tested for "Rickettsia felis" infection. They see as very real, the possibility that "Rickettsia felis" might be the next mosquito-borne pathogen to emerge as a multi-continental disease outbreak.
