One of the constraints to controlling foot-and-mouth disease (FMD) in East Africa is the incomplete knowledge of the specific FMD virus (FMDV) strains circulating, and the way in which these viruses move across countries in the region. This retrospective study focuses on…

The positive stranded RNA genomes of picornaviruses comprise a single large open reading frame flanked by 5' and 3' untranslated regions (UTRs). Foot-and-mouth disease virus (FMDV) has an unusually large 5' UTR (1.3 kb) containing five structural domains. These include the…

Developing a vaccine to protect against the lethal effects of the many strains of coronavirus is critical given the current global pandemic. For Middle East respiratory syndrome coronavirus (MERS-CoV), we show that rhesus macaques seroconverted rapidly after a single…

Modern phylogeography aims at reconstructing the geographic diffusion of organisms based on their genomic sequences and spatial information. Phylogeographic approaches usually ignore the possibility of recombination, which decouples the evolutionary and geographic histories…

Mycobacterium tuberculosis ( M.tb) infection results in approximately 1.3 million human deaths each year. M.tb resides primarily inside macrophages, and maintains persistent infection. In response to infection and inflammation, platelet activating factor C-16 (PAF C-16), a…

African horse sickness was confirmed in horses in Thailand during March 2020. The virus was determined to belong to serotype 1 and is phylogenetically closely related to isolates from South Africa. This is the first incidence of African horse sickness occurring in Southeast…

Gammacoronavirus infectious bronchitis virus (IBV) causes an economically important respiratory disease of poultry. Protective immunity is associated with the major structural protein, spike (S) glycoprotein, which induces neutralising antibodies and defines the serotype…

Avian influenza viruses of the subtype H6Nx are being detected globally with increasing frequency. Some H6Nx lineages are becoming enzootic in Asian poultry and sporadic incursions into European poultry are occurring more frequently. H6Nx viruses that contain mammalian…

Background: Reverse genetics is used in many laboratories around the world and enables the creation of tailormade influenza viruses with a desired genotype or phenotype. However, the process is not flawless, and difficulties remain during cloning of influenza gene segments…
