Results from in-house assays to detect cattle or sheep IgG against 3ABC were compared with those from a commercially available test kit in naïve or infected animals, and those first vaccinated then challenged with foot-and-mouth disease virus (FMDV) type O. Bovine IgG1 could be detected 7 days post infection or challenge (dpi or dpc) using the in-house method (3 days after neutralising antibodi...
Mx proteins belonging to the dynamin superfamily of large GTPases inhibit replication of a wide range of RNA viruses. In this study, we examined whether bovine Mx1 protein could interfere with the replication of foot-and-mouth disease virus (FMDV). For this purpose we established cloned BHK-21 cells expressing bovine Mx1 protein (BM1 cells) and infected them with FMDV serotype O. Cloned BHK-21 ...
Hand, foot and mouth disease, that was once considered a disease of cattle, has been emerging as a common human childhood disease in the last few years. It is a viral disease characterized by a brief febrile illness and typical vesicular rashes. In rare cases, patients may also develop neurological complications. This report describes a case of hand, foot and mouth disease, presented with typic...
Auto-processing of the non-structural polypeptide 3ABC of foot and mouth disease virus (FMDV) expressed in Escherichia coli-BL21-DE3 was prevented by mutating either four glutamic acid residues at the 3A/3B1, 3B1/2, 3B2/3 and 3B3/3C junctions (3ABCtet) or a single cysteine residue at position 383 within the 3C domain (3ABCm). Independent expression of 3ABC and 3ABCtet genes induced expression o...
This study provides a comprehensive overview of the molecular epidemiology of human enterovirus 71 (HEV71) in the Asia-Pacific region from 1997 through 2002. Phylogenetic analysis of the VP4 and VP1 genes of recent HEV71 strains indicates that several genogroups of the virus have been circulating in the Asia-Pacific region since 1997. The first of these recent outbreaks, described in Sarawak (M...
All known field isolates of enterovirus 71 (EV71) can be divided into three distinct genogroups (A, B, C) and 10 subgenogroups (A, B1-5, C1-4) based on VP1 gene sequences. We examined VP1 gene sequences of 10, 12 and 11 EV71 strains isolated in peninsular Malaysia during the outbreaks of hand, foot and mouth disease in 1997, 2000 and 2005 respectively. Four EV71 strains isolated in the hand, fo...
After a 16-year interval, foot-and-mouth disease virus serotype SAT 3 was isolated in 2013 from an apparently healthy long-horned Ankole calf that grazed close to buffalo in Uganda. The emergent virus strain is ≈20% different in nucleotide sequence (encoding VP1 [viral protein 1]) from its closest relatives isolated previously from buffalo in Uganda.
Foot-and-mouth disease virus (FMDV) causes a highly infectious and economically devastating disease of livestock. The FMDV genome is translated as a single polypeptide precursor that is cleaved into functional proteins predominantly by the highly conserved viral 3C protease, making this enzyme an attractive target for antiviral drugs. A peptide corresponding to an optimal substrate has been mod...
Evidence for a mechanism of initiation of viral persistence in which the cell, and not the virus, plays a critical role has been obtained using the important animal pathogen foot-and-mouth disease virus (FMDV). We have developed a virulence assay consisting of quantification of the ability of virus to kill cells and of cells to divide in the presence of virus and to initiate a carrier state. Ce...
