Foot-and-mouth disease (FMD) is a contagious viral disease of livestock with significant economic effect. It is prevalent in various regions of Asia, Africa, and South America. The causative agent of this disease is called foot-and-mouth disease virus (FMDV), which is a member of Aphthovirus genus. Vaccination is an effective technique to prevent the complications of FMD and to eradicate the di...

BACKGROUND Ethiopian livestock production and productivity is still very low due to widespread of diseases. Among the diseases, foot-and-mouth disease (FMD) is an extremely contagious and acute viral disease that causes significant economic problems in the country. A cross sectional study design was conducted from September 2015 to May 2016 to isolate and characterize FMD virus from outbreak ca...

Foot-and-mouth disease virus (FMDV) 3C protease (3C(pro)) plays a vital role in virus replication by performing most of the cleavages required to divide the viral polyprotein precursor into its functional component proteins. To date, no structural information has been available for FMDV 3C(pro), which is an attractive target for antiviral drugs. Targeted mutagenesis of surface amino acids ident...

A biotinylated 3ABC recombinant protein was developed and used in a competitive ELISA (cELISA) to detect foot-and-mouth disease virus (FMDV) antibodies in cattle, sheep and pigs. In this report, we describe the cloning and expression of 3ABC protein in Escherichia coli cells as fusion protein with 6xHis and biotin. This cELISA uses streptavidin to capture bacterially expressed and in vivo bioti...

Five groups of ten animals were vaccinated with a combined vaccine containing foot and mouth disease (FMD), rabies, Pasteurella multocida and Clostridium chauvoei antigens and individual component vaccines containing FMD, rabies, Pasteurella multocida and Clostridium chauvoei antigens, respectively. Serological response of the calves was assayed on days 21 and 90 post vaccination. There was no ...

We have previously documented the inhibitory activity of RNA aptamers to the RNA-dependent RNA polymerase of foot-and-mouth disease virus (3D(pol)). Here we report their modification and use with a subgenomic replicon incorporating GFP (pGFP-PAC replicon), allowing replication to be monitored and quantified in real-time. GFP expression in transfected BHK-21 cells reached a maximum at approximat...

The internal ribosome entry site (IRES) elements of cardioviruses (e.g., encephalomyocarditis virus [EMCV] and foot-and-mouth disease virus) are predicted to have very similar secondary structures. Among these complex RNA structures there is only rather limited complete sequence conservation. Within the J domain of the EMCV IRES there are four highly conserved nucleotides (A704, C705, G723, and...

The effect of deletion of each of the two authentic polyprotein translation initiation sites of foot-and-mouth disease virus on viral protein synthesis and replication was analyzed. Deletion of either the first or the second initiation site led to the expression of only one form of the leader protein, L or L', respectively, but in vitro processing of the viral polyprotein and cleavage of eIF-4 ...

A region of about 435 bases from the 5' noncoding region of foot-and-mouth disease virus RNA directs internal initiation of protein synthesis. This region, termed the internal ribosome entry site (IRES), is predicted to contain extensive secondary structure. Precise deletion of five predicted secondary structure features has been performed. The mutant IRES elements have been constructed into ve...

Foot-and-mouth disease virus (FMDV) causes a highly contagious viral disease of even-toed ungulates and is one of the most important economic diseases of livestock. Most studies of FMDV are done in countries where control measures are being implemented. In contrast, in areas such as sub-Saharan Africa, where FMDV is endemic and new strains are likely to emerge, there are only sporadic submissio...
