Sequencing and subsequent analysis of a vaccine strain of foot-and-mouth disease virus serotype O is reported here. Genomic heterogeneity in the protective epitopes (VP1 protein) of the reported strain, compared to characterized strains and available sequences from Pakistan, warrants further studies to determine vaccine-induced immunity and disease protection.
A microneutralization test for foot-and-mouth disease virus antibodies is described and compared to the standard mouse test.
Synthetic 2-stranded RNA-a helical complex formed by duplexing homopolymers of polyriboinosinic and polyribocytidylic acids (poly I:C)-induced host resistance to foot-and-mouth disease virus when microgram quantities were injected into mice. There was a graded response as shown by titrations of polynucleotide complex or virus. Protection was effective for >48 hours after a single injection of p...
Relationship of the antigenic structure of foot-and-mouth disease virus to the process of infection.
The profiles of virus production and excretion have been established for sheep experimentally infected with the UK 2001 strain of foot-and-mouth disease (FMD) virus by inoculation and by direct and intensive contact. Virus replicated rapidly in the inoculated sheep, from which a peak infectivity of airborne virus of 10(4.3) TCID(50) per sheep per 24 h was recovered. Around 24 h later, contact-i...
The effectiveness of a vaccine preserved for emergency use in Japan was analyzed under experimental conditions using cows and pigs in order to retrospectively evaluate the effectiveness of the emergency vaccination performed in the 2010 epidemic in Japan. Cows and pigs were administered a vaccine preserved for emergency use in Japan at 3 or 30 days before virus infection (dbv) and were subseque...
The replication of many viruses involves the formation of higher-order structures or replication "factories." We show that the key replication enzyme of foot-and-mouth disease virus (FMDV), the RNA-dependent RNA polymerase, forms fibrils in vitro. Although there are similarities with previously characterized poliovirus polymerase fibrils, FMDV fibrils are narrower, are composed of both protein ...
Despite significant advances made in the understanding of its epidemiology, foot and mouth disease virus (FMDV) is among the most unexpected agricultural devastating plagues. While the disease manifests itself as seven immunologically distinct strains their origin, population dynamics, migration patterns and divergence times remain unknown. Herein we have assembled a comprehensive data set of g...
