Infected ticks are thought to serve as vectors of transmission. Transmission among pigs can also occur directly or through contaminated food. The illness produced is known as African swine fever; it is highly…

AFP is a plasma protein that is normally produced by the fetus. It serves as the basis for some valuable tests. AFP is manufactured principally in the fetus’s liver and, also, in the fetal gastrointestinal (GI) tract and the yolk sac, a structure temporarily present during embryonic development. The level of AFP is typically high in the…
