Assessment of Foot and Mouth Virus Subtype O2016 Genetic Alterations During Successive Passages in BHK Monolayer

Rapid selection in modified BHK-21 cells of a foot-and-mouth disease virus variant showing alterations in cell tropism.

With persistent foot-and-mouth disease virus (FMDV) in BHK-21 cells, there is coevolution of the cells and the resident virus; the virulence of the virus for the parental BHK-21 cells is gradually increased, and the cells become partially resistant to FMDV. Here we report that variants of FMDV C3Arg/85 were selected in a single infection of partially resistant BHK-21 cells (termed BHK-Rb cells)...

Lyophilizing Foot-and Mouth Disease Virus at Low Drying Temperature

The situation of foot and mouth disease virus types and subtypes in Iran in 1980-1983

Genetic stability of foot-and-mouth disease virus during long-term infections in natural hosts

Foot-and-mouth disease (FMD) is a severe infection caused by a picornavirus that affects livestock and wildlife. Persistence in ruminants is a well-documented feature of Foot-and-mouth disease virus (FMDV) pathogenesis and a major concern for disease control. Persistently infected animals harbor virus for extended periods, providing a unique opportunity to study within-host virus evolution. Thi...

Organic Circulation and persistence of Foot – and – Mouth disease virus type O in guinea pig

Since, the most susceptible laboratory animal to Foot–and–Mouth disease virus (FMDV) is guinea pig, and then one milliliter of FMDV type (O) concentrations of 106-106.5 TCID50was inoculated intradermally (ID) to 10 plantar surface of guinea pig (right side). Guinea pig adapted virus has been prepared after generalization phase, and then one milliliter of virus was inoculated intradermally to 30...

Nucleotide mismatches of foot-and-mouth disease virus during replication.

As there is a lack of error correction mechanisms during RNA replication, foot-and-mouth disease virus (FMDV) has a very high mismatch rate, which leads to a high mutation rate, in the range of 10(-3) to 10(-5) per nucleotide site per genome replication. We examined the nucleotide mismatch of FMDV during replication, based on the whole genomes of the 7 serotypes retrieved from NCBI. With the Me...
