“…For example, in our study blocks we detected Psorophora (especially cingulata ), Mansonia and Coquillettidia species, which have been shown to be competent vectors in the laboratory [48],[49]. Additionally, Aedes aegypti has been shown to be a competent vector of both enzootic [50] and epizootic VEEV in the laboratory [51],[52],[53],[54] and is present throughout the city of Iquitos. While feeding preference, as well as temporal and spatial distribution, argues against a role for Aedes aegypti in VEEV transmission cycles in Iquitos, the possibility warrants further examination.…”

Venezuelan Equine Encephalitis Virus in Iquitos, Peru: Urban Transmission of a Sylvatic Strain

Enzootic strains of Venezuelan equine encephalitis virus (VEEV) have been isolated from febrile patients in the Peruvian Amazon Basin at low but consistent levels since the early 1990s. Through a clinic-based febrile surveillance program, we detected an outbreak of VEEV infections in Iquitos, Peru, in the first half of 2006. The majority of these patients resided within urban areas of Iquitos, with no report of recent travel outside the city. To characterize the risk factors for VEEV infection within the city, an antibody prevalence study was carried out in a geographically stratified sample of urban areas of Iquitos. Additionally, entomological surveys were conducted to determine if previously incriminated vectors of enzootic VEEV were present within the city. We found that greater than 23% of Iquitos residents carried neutralizing antibodies against VEEV, with significant associations between increased antibody prevalence and age, occupation, mosquito net use, and overnight travel. Furthermore, potential vector mosquitoes were widely distributed across the city. Our results suggest that while VEEV infection is more common in rural areas, transmission also occurs within urban areas of Iquitos, and that further studies are warranted to identify the precise vectors and reservoirs involved in urban VEEV transmission.

“…Similar results were reported by Wikel (1982) with the tick Dermacentor andersoni and the tick borne bacterial pathogen Francisella tularensis. This suggests a possible method of reducing transmission to immunized hosts although experiments involving the natural transmission of the Venezuelan equine encephalomyelitis virus to immune hosts produced equivocal results (Mellink, 1982). aegypti mosquitoes neutralized Sindbis virus in vitro, most probably due to the reaction of the antibodies with mosquito antigens incorporated into the viral envelope (Feihsod et al, 1975).…”

Cellular and humoral immune responses against arthropod vector antigens in invertebrate hosts affect vector physiology and significantly modulate the transmission of pathogens. This phenomenon may be the basis for novel methods of disease control based on immunization against arthropod antigens. Current research in this field is briefly reviewed.Resume-Des reactions cellulaires et humorales contre des antigens de vecteurs arthropodes dans des notes verte bres affectent la physiologie et modulent de fac.on significative la transmission de pathogenes. Le phenomene peut etre a la base de nouvelles methodes de controle des maladies basees sur Fimmunization contre des antigenes d'arthropodes. La recherche actuelle dans ce domaine est brievement resumee.
