Cell surface antigen induced by venezuelan equine encephalomyelitis virus.
By immunofluorescence staining, a specific surface antigen induced by Venezuelan equine encephalomyelitis virus was detected on L-929 cells. Formation of the antigen was independent of viral ribonucleic acid synthesis.
متن کاملSusceptibility of white Carneau pigeons to respiratory infection by Venezuelan equine encephalitis virus.
It has been found that certain arbovirvises may be transmitted among avian hosts by modes other than mosquito bite. Holden (1) demonstrated contact transmission of Eastern equine encephalitis (EEE) virus among penned pheasants. He postulated that infections resulted from ingestion of infected materials or by inhalation of infective droplets. Chamberlain and others (2) observed contact infection...
متن کاملVenezuelan equine encephalitis emergence: enhanced vector infection from a single amino acid substitution in the envelope glycoprotein.
In 1993 and 1996, subtype IE Venezuelan equine encephalitis (VEE) virus caused epizootics in the Mexican states of Chiapas and Oaxaca. Previously, only subtype IAB and IC VEE virus strains had been associated with major outbreaks of equine and human disease. The IAB and IC epizootics are believed to emerge via adaptation of enzootic (sylvatic, equine-avirulent) strains for high titer equine vir...
متن کاملPurification, concentration, and inactivation of Venezuelan equine encephalitis virus.
Venezuelan equine encephalitis (VEE) virus was purified and concentrated by chromatography of tissue culture supernatant fluids on diethylaminoethyl-cellulose columns. Stepwise gradient elution studies indicated a broad elution pattern for the virus, with recovery occurring from 0.05 to 0.7 m NaCl. Optical density, infectivity, hemagglutination (HA), and complement fixation (CF) assays indicate...
متن کاملNonviable Venezuelan equine encephalomyelitis hemagglutinin prepared from tissue cultures by gamma radiation.
Hemagglutinins of Venezuelan equine encephalomyelitis virus were produced in tissue cultures, and the infective virus was rendered nonviable by exposure to gamma radiation.
