The etiology of malaria is a study of paramount importance to the practitioner of tropical medicine. In different regions, the intensity of the poison may, to some degree, vary ; but in India, from Karachi to Sudia and Sirhind to Cape Comoriu, malaria is the cause of a greater total of sickness than perhaps all other diseases combined. Few of its inhabitants get through twelve months without au...

Mesenteronal infection and transmission thresholds for several Middle American epizootic and enzootic Venezuelan equine encephalomyelitis (VEE) viruses were evaluated in field-collected (Guatemala) and colonized individuals of the enzootic vector mosquito Culex (Melanoconion) taeniopus. Approximate thresholds for 3 epizootic, hemagglutination-inhibition (HI) subtype I-AB strains were 10 chick e...

online | memorias.ioc.fiocruz.br The urban presence of Lutzomyia longipalpis (Lutz & Neiva, 1912) (Salomón & Orellano 2005) was first recorded in Argentina in Formosa province in 2004; it was associated with an outbreak of visceral leishmaniasis (VL) in the neighbouring city of Asunción, Paraguay Republic.

During a 4-year period (1972-1975), mosquitoes were collected, identified, and processed for virus isolation. Laboratory examinations of clinical specimens from suspected encephalitis cases were made to provide etiologic diagnosis. Arbovirus was isolated from 102 pools of mosquitoes (2 LaCrosse, 2 Cache Valley, 10 Flanders, 3 St. Louis Considerable interest in arbovirus surveillance activity wa...

The efficiency of miniature CDC light-traps in catching West African malaria vectors was evaluated during two rainy seasons in a village near Ouagadougou, Burkina Faso. Traps were employed both indoors and outdoors using human baits protected by an insecticide-free mosquito-net and different sources of light. Indoors, light from incandescent bulbs increased the catch of Anopheles gambiae s.l. (...

First-generation progeny of field-collected Psorophora ferox, Aedes scapularis, and Aedes serratus from the Rocio encephalitis epidemic zone in S.Paulo State, Brazil, were tested for vector competency in the laboratory. Psorophora ferox and Ae. scapularis are susceptible to per os infection with Rocio virus and can transmit the virus by bite following a suitable incubation period. Oral ID50S fo...
