We investigated the molecular epidemiology of foot-and-mouth disease virus (FMDV) serotype Asia 1, which caused outbreaks of disease in Asia during 2003-2007. Since 2004, the region affected by outbreaks of this serotype has increased from disease-endemic countries in southern Asia (Afghanistan, India, Iran, Nepal, Pakistan) northward to encompass(More)
A selection of type O foot-and-mouth disease (FMD) viruses isolated in Thailand between 1986 and 1989 were compared to the reference viruses O1 Thailand 1960 (O BKK/60) and O Nakorn Pathom 1965 (O NPT/65) using a liquid-phase blocking ELISA (LP ELISA) to derive serum titres and associated r values. Interpolation techniques were used to increase the(More)
Forty peptides were synthesized corresponding to hydrophilic clusters of amino acids within the sequences of foot-and-mouth disease virus (FMDV) nonstructural proteins (NSP). Six peptides were studied in more detail and the most promising, a 2B peptide, was evaluated in enzyme-linked immunosorbent assay (ELISA) using sera from naive, vaccinated, and(More)
Foot and mouth disease, a highly contagious disease of cloven-hoofed animals, is still endemic in Asia, Africa, and a few countries in South America. Subclinical and persistent infections usually occur in vaccinated cattle exposed to FMDV. Successful control and eradication measures need a diagnostic assay that can distinguish between immune responses to(More)
Antisera were produced at a central laboratory in Thailand against the endemic serotypes (O, A and Asia 1) of foot and mouth disease (FMD) virus. At a regional veterinary laboratory, these antisera were used in an indirect sandwich enzyme-linked immunosorbent assay (ELISA) for the detection and serotyping of FMD virus (FMDV) antigen. ELISA readings of <(More)
Introduction: Recently there has been an apparent increase of outbreaks due to foot-and-mouth disease (FMD) Asia 1. Spread has occurred into regions where this serotype has never or rarely been recorded People’s Republic of China (including Hong Kong), Russian Federation and Mongolia. To determine the relationships between FMD virus isolates from the(More)
OBJECTIVE To measure the diagnostic performance of an Australian-developed ELISA for the detection of antibodies against the non-structural proteins (NSP) 3ABC of the foot and mouth disease (FMD) virus. DESIGN Test development and validation study. METHODS The diagnostic specificity was determined using 2535 sera from naïve animals and 1112 sera from(More)
