چکیده

Antigenic variation of type A foot and mouth disease (FMD) virus in Thailand was examined using a total of 82 field viruses isolated between 1986 and 1989. A two-dimensional serum microneutralisation test was used to compare these isolates to a reference strain, A15 Bangkok 1960 (A BKK/60). Viruses regarded as unrelated to A BKK/60 were compared to another reference strain, A22 Nakhon Pathom 1986 (A NPT/86). This approach divided the viruses into two groups. Most of the viruses shared a close antigenic relationship with A BKK/60. Only twelve viruses were regarded as unrelated to A BKK/60, and these were related to A NPT/86. All but one of these twelve isolates were from two provinces in one administrative region of the country. Future type A vaccines in Thailand will need to confer protection against both groups of viruses.

Serological comparison of type Asia 1 foot and mouth disease virus isolates from Thailand.

Antigenic variation of type Asia 1 foot and mouth disease (FMD) virus in Thailand was examined using a total of 50 field viruses isolated between 1986 and 1992. A two-dimensional serum neutralisation test was used to calculate r values for comparison of these isolates with a reference vaccine strain, Asia 1 Bangkok 1960 (BKK/60). Viruses were also compared to two field isolates, Asia 1 36-2/88 ...

A comparison of type O foot and mouth disease virus field isolates from northern Thailand.

A survey of type O foot and mouth disease (FMD) virus isolates from northern Thailand was undertaken to determine the relationship between field viruses and the vaccine in use, and to gauge the range of antigenic variation among field viruses. Isolates were collected from the two most recent epizootics, 1986-1987 and 1989-1990, and assessed using a two-dimensional neutralisation test to determi...

A serological study of Indian type O foot and mouth disease virus isolates

Serological relationships between six type O FMD virus iso­ lates from different parts of India were studied using two-dimensional microneutralisation tests. All the strains in the study were shown to be related to the O5 subtype. The vaccine strain, O India 53/79, exhibited the broadest serological spectrum, although small differences were observed with isolates from Northern and Western India...

Rapid and accurate diagnosis of Foot-and-mouth disease virus by Real-time PCR in field samples

During 2010-2011, Real-time PCR procedure was used to detecting FMDV RNA on 147 epithelium samples from the field. In this survey, for Real-time PCR from 3D gene segment as conserve region selected for tracking all of seven serotypes FMDV. The assay detected the viral RNA in all serotypes of FMDV. The rRT-PCR specifically detected FMD virus in sample with greater sensitivity than our convention...
