Studies were carried out on morphologic changes in 27 pigs experimentally infected with a virulent virus of the African swine fever and in 61 pigs that has spontaneously developed the acute form of the disease. A description and 11 colour plates are given of the characteristic gross and microscopic
African swine fever (ASF) is a devastating haemorrhagic fever of pigs that causes up to 100% mortality, for which there is no vaccine. It is caused by a unique DNA virus that is maintained in an ancient cycle between warthogs and argasid ticks, making it the only known DNA arbovirus. ASF has a high
BACKGROUND
The West-African (WA) Zaire Ebolavirus disease (EVD) outbreak was characterized by an exceptionally high number of cases and deaths as compared with the Eastern-Central African (ECA) outbreaks. Despite the Zaire Ebolavirus being the most lethal for humans, case-fatality rate, close to 80
Three hemorrhagic fevers occur in southern Africa: Rift Valley fever, Marburg virus disease, and Crimean-Congo hemorrhagic fever. The patient's history of travel in Africa, visits to rural areas, contact with sick animals or their carcasses, or contact with a tick-infested environment or tick bites
African swine fever virus (ASFV) is a large, intracytoplasmically-replicating DNA arbovirus and the sole member of the family Asfarviridae. It is the etiologic agent of a highly lethal hemorrhagic disease of domestic swine and therefore extensively studied to elucidate the structures, genes, and
Physicians may encounter unfamiliar diseases as a result of international travel. Fever with rash is an important sign that usually represents initial manifestation of infectious disorders. A 62-year-old Taiwanese woman presented with multiple eschars, a papulovesicular rash, and fever 5 days after
Through its role in lipid metabolism, Apolipoprotein epsilon4 (ApoE4) may affect "brain repair" in stroke, brain hemorrhage, Alzheimer's disease, and other brain injury syndromes for which African Americans may have greater morbidity and mortality. Cross-cultural evaluations of these and other
The aetiological factors in 84 patients with acute upper gastrointestinal tract(UGIT) haemorrhage were studied. Sixty of the patients (71.4%) were between their 3rd and 5th decades of life. Acute alcohol consumption and drugs are the commonest single or combined factors in 76 patients (90.5%).
African swine fever (ASF) is one of the most complex livestock diseases. The significant losses that it causes, coupled with the lack of a vaccine against ASF virus and the possible resemblance with other swine hemorrhagic diseases, make early detection and laboratory diagnosis essential for
