Revisión bibliográfica sobre la fisiopatología de la Peste Porcina Africana (PPA)

Abstract

Introduction. African Swine Fever that affects wild and domestic swine. It is a very contagious disease, and lethal that causes great economic loss. It reaches 100% mortality and death, because they are obligated to sacrifice infected animals and animals suspected of having the disease. It is obligatory to inform the World Organization for Animal Health (WOAH). Objective. This revision wishes to contribute with relevant facts about scientific advances that describe the Physiopathology of African Swine Fever (ASF). Methodology. A documental investigation was realized, both critical and descriptive, which permitted obtaining information about the physiopathology of the African Swine Fever. (ASF). Utilizing as its basis scientific facts. 39 written articles were used in Spanish and English from the year 2018 to 2023. Discussion. The virus originated in Africa and was found on that continent and others such as Europe, Asia, Ocean, and America affecting 50 counties around the world. Morphologic and biochemically the virus is complex and can resist distinct environmental conditions that inactivate with heat but resist low temperatures. The clinical conditions that are displayed in (ASF) are Hyper-severe, severe, sub-severe chronic and asymptomatic. The Hyper-severe types produce sudden death, and when moderate or asymptomatic, the animal survives the infection, and the virus continues converting them into healthy carriers. Conclusion. African Swine Fever (ASF) is a worldwide threat to the swine industry. Its complex interaction with the immune system, the quickness with which it expands, the lack of an effective treatment, and the inexistence of a commercial vaccine makes this disease a huge challenge for the worldwide swine sector.
