and Argentina are free of human rabies transmitted by dogs, although there are certain areas to which this disease is still endemic (1). Coordinated actions for regional elimination of human rabies transmitted by dogs began in 1983 in Latin America and the Caribbean with the assistance of the Pan American Health Organization (PAHO). This effort has led to(More)
A multiplex, real-time reverse transcription-polymerase chain reaction (RT-PCR) assay was developed that allowed simultaneous detection and rapid differentiation of vesicular stomatitis virus strains--New Jersey (VSV-NJ) and Indiana 1, 2, and 3 (VSV-IN1-3). This assay involves use of a set of VSV universal primers located in the L gene that amplify(More)
Two foot-and-mouth disease virus (FMDV) monoclonal antibodies (mAbs) were produced from mice immunized with either FMDV serotype A, subunit (12S) or FMDV serotype O, whole virus (140S). Both mAbs (F1412SA and F21140SO) recognized all seven serotypes of FMDV in a double antibody sandwich (DAS) ELISA, suggesting that the binding epitopes of the two mAbs are(More)
A serologic survey of influenza A antibodies was undertaken on 1,611 blood samples from five species of marine mammals collected from Arctic Canada from 1984-98. Sampling was done in 24 locations throughout the Canadian Arctic encompassing Sachs Harbor (72 degrees N, 125 degrees W), Northwest Territories in the west to Loks Land (63 degrees N, 64 degrees(More)
The objective of this study was to investigate the inactivation and degradation of foot-and-mouth disease (FMD) virus during composting of infected pig carcasses as measured by virus isolation in tissue culture and by real-time reverse transcriptase polymerase chain reaction (RRT-PCR). Three FMD-infected pig carcasses were composted in a mixture of chicken(More)
In September 1999, unusually high mortality rates in white-tailed deer and California bighorn sheep occurred in the southern Okanagan Valley. Necropsy and histopathologic findings were compatible with epizootic hemorrhagic disease (EHD); the presence of virus was not demonstrated. Subsequent serologic and polymerase chain reaction assays on sentinel cattle(More)
Foot-and-mouth disease (FMD) is a highly contagious and economically significant disease of cattle, pigs, sheep, goats and wild ruminant species. The FMD virus genome encodes a unique polyprotein from which the different viral polypeptides are cleaved by viral proteases, including eight different non-structural proteins (NSPs). Both structural and(More)
The ability to discriminate between different classical Swine fever virus (CSFV) isolates is a prerequisite for identifying the possible origin of an outbreak. To determine the relatedness between Colombian isolates from different geographical regions, genetic sequences of the glycoprotein E2 and the 5'UTR of CSFV were amplified by PCR, sequenced and(More)
The foot-and-mouth disease virus (FMDV) is a member of the picornavirus family, possessing an 8-kb single-stranded RNA genome of positive polarity. It is highly contagious among several livestock species and can lead to severe economic consequences, as evidenced by the UK outbreak in 2001. The usage of real-time polymerase chain reaction has facilitated(More)
A biotinylated 3ABC recombinant protein was developed and used in a competitive ELISA (cELISA) to detect foot-and-mouth disease virus (FMDV) antibodies in cattle, sheep and pigs. In this report, we describe the cloning and expression of 3ABC protein in Escherichia coli cells as fusion protein with 6xHis and biotin. This cELISA uses streptavidin to capture(More)
