Potential antigen in combating the pervasive threat of the Malaysian foot and mouth disease virus (FMDV) in ruminant
Foot-and-mouth disease (FMD) is a major infectious disease caused by the foot-and-mouth disease virus (FMDV) that affects the domestic and foreign trade in livestock and animal products, resulting in high economic losses and social consequences.

| description | Foot-and-mouth disease (FMD) is a major infectious disease caused by the foot-and-mouth disease
virus (FMDV) that affects the domestic and foreign trade in livestock and animal products,
resulting in high economic losses and social consequences. Current control of FMD includes
prevention by vaccination with inactivated vaccines. However, various challenges arise, including
difficulty handling multiple serotypes, due to the vaccines specific for a single serotype and
providing short-term immunity. Previous studies have utilised capsid protein, P1 which encodes
four structural proteins (VP4, VP2, VP3, and VP1) of the FMDV to develop potential vaccines
due to antigenic variation. Despite this, the antigenicity of the Malaysian FMDV capsid protein is
not well studied. This study aims to characterise the Malaysian FMDV serotypes O and A capsid
protein via in silico and in vitro analysis. The FMDV serotypes O and A capsid protein sequences
were identified based on the FMD outbreaks in Malaysia and the antigenicity was predicted by
bioinformatics approaches and computational techniques. Then, the antigenic genes were cloned
into an expression vector, pET-28a and further manipulated for protein expression analysis. The
capsid proteins were predicted to be antigenic by Kolaskar and Tongaonkar's semi-empirical
method. The antigenic genes were successfully characterised and expressed in E. coli BL21(DE3).
The results provide information on the stability of the capsid protein and the future ability to elicit
immune responses. Therefore, this research can be utilized to design a novel vaccine to combat
FMD in ruminants. |
