Manadas de caballos como centinelas para detectar la actividad del virus de la encefalitis equina venezolana en Nicaragua, 1977 / Equine herds as sentinels for Venezuelan equine encephalitis virus activity in Nicaragua, 1977

Los sueros tomados de 93 caballos en ranchos nicaragüenses y las pruebas serológicas que se practicaron para detectar en ellos la presencia de anticuerpos del virus de la encefalitis equina venezolana (EEV), muestran que tales caballos pueden servir de centinelas baratos y eficaces para detectar la actividad de ese virus (AU)

Search for subtype I strains of Venezuelan encephalitis virus among isolates from Trinidad, W.I., during 1960-1972

Twenty-one strains of Venezuelan encephalitis (VE) virus isolated from three habitats in Trinidad, W. I. during 1960 to 1972, were subtype III (Mucambo) VE cirus by plaque-reduction neutralization tests. Like prototype Mucambo virus, each strain killed 8- to 15-week-old mice inoculated intraperitoneally. If the subtype I strain of VE virus that caused a major outbreak in Trinidad during 1943 to 1944 persisted on the island into the 1960s and early 1970s, it did not become the dominant VE virus in these three enzootic foci (AU)

Los primeros aislamientos de arbovirus de encefalitis del este y de grupos C y Guama en la región amazónica del Perú / The first isolation of Eastern Encephalitis, group C, and Guama group arboviruses from the Peruvian Amazon region of Western South America

Se describen los primeros aislamientos de arbovirus de encefalitis del este y grupos C y Guama obtenidos en la región amazónica del Perú, en Sudamérica occidental. A medida que se desarrolle esta región y aumenten las poblaciones humanas y equinas, las enfermedades causadas por estos virus pueden convertirse en una grave amenaza para la salud pública (AU)

The first isolations of eastern encephalitis, group C, and Guama group arboviruses from the Peruvian Amazon region of western South America

Two strains of eastern encephalitis (EE) virus were isolated in the Amazon region of Peru near Pucallpa, Loreto Department, using sentinel hamsters. EE virus antibodies were found in healthy horses at both Pucallpa and Iquitos in the same Department. Fourteen group C and four Guama group arboviruses were recovered from sentenel hamsters and mosquitoes near Iquitos. The group C agents were Caraparu-Ossa, Marituba, and Oriboca-Itaqui viruses, and the Guama group agents were Bimiti virus. Besides providing a detailed account of these investigations, this article includes a current list of known arboviruses of the American tropics that can be detected with sentinel hamsters (Au)

Studies of Patois group arboviruses in Mexico, Guatemala, Honduras, and British Honduras

Patois, Zegla, and Shark River-like arboviruses in the Patois group were isolaed in Mexico, Guatemala, Honduras, and British Honduras during 1963 to 1968. Twenty-three Patois viruses came from mosquitoes, sentinel hamsters, and suckling mice, 21 Zegla viruses from sentinel hamsters and mice and from a wild cotton rat, and two Shark River-like viruses from sentinel hamsters. Hemagglutination-inhibition(HI) and neutralizing antibody tests with Patois virus were positive with human sera from each country, and HI antibody tests were positive with sera from pigs in Mexico, Guatemala, and British Honduras and from small wild mammals, wild birds, and cattle in Mexico.(AU)
