1,5-Iodonaphthyl azide-inactivated V3526 protects against aerosol challenge with virulent venezuelan equine encephalitis virus.
Venezuelan equine encephalitis virus (VEEV) is a New World alphavirus. VEEV is highly infectious in aerosolized form and has been identified as a bio-terrorism agent. There is no licensed vaccine for prophylaxis against VEEV. The current IND vaccine is poorly immunogenic and does not protect against an aerosol challenge with virulent VEEV. We have previously shown that VEEV inactivated by 1,5-i...
متن کاملProtection of hamsters by Venezuelan equine encephalitis virus candidate vaccine V3526 against lethal challenge by mosquito bite and intraperitoneal injection.
In an attempt to improve the current live, attenuated vaccine (TC-83) for Venezuelan equine encephalitis virus (VEEV), specific mutations associated with attenuation of VEEV in rodent models were inserted into a full-length cDNA clone of the Trinidad donkey strain of VEEV by site-directed mutagenesis. Because some viruses have been reported to be more pathogenic when introduced by mosquito bite...
متن کاملSafety and protective efficacy of INA-inactivated Venezuelan equine encephalitis virus: implication in vaccine development.
We have previously shown that a hydrophobic alkylating compound, 1,5-iodonaphthyl-azide (INA) can efficiently inactivate the virulent strain of Venezuelan equine encephalitis virus (VEEV), V3000 in vitro. In this study, we have evaluated the safety of INA-inactivated V3000 and V3526 and the protective efficacy of INA-inactivated V3000. INA-inactivated V3000 and V3526 did not cause disease in su...
متن کاملAstrocytes as targets for Venezuelan equine encephalitis virus infection.
Venezuelan equine encephalitis virus (VEE) produces an acute infection in humans and induces a well-characterized cytopathic effect in neurons of the central nervous system (CNS). However, little is known about the role of glial cells in response to VEE infection of the CNS. Our results demonstrate that VEE is capable of a productive infection in primary astrocyte cultures and that this infecti...
متن کاملVenezuelan Equine Encephalitis Virus, Southern Mexico
Equine epizootics of Venezuelan equine encephalitis (VEE) occurred in the southern Mexican states of Chiapas in 1993 and Oaxaca in 1996. To assess the impact of continuing circulation of VEE virus (VEEV) on human and animal populations, serologic and viral isolation studies were conducted in 2000 to 2001 in Chiapas State. Human serosurveys and risk analyses indicated that long-term endemic tran...
