Reemergence of African Swine Fever in Zimbabwe, 2015

Small-scale pig farmers’ behavior, silent release of African swine fever virus and consequences for disease spread

The expanding distribution of African swine fever (ASF) is threatening the pig industry worldwide. Most outbreaks occur in backyard and small-scale herds, where poor farmers often attempt to limit the disease's economic consequences by the emergency sale of their pigs. The risk of African swine fever virus (ASFV) release via this emergency sale was investigated. Simulation modeling was used to ...

Comparative Analysis of African Swine Fever Virus Genotypes and Serogroups

African swine fever virus (ASFV) causes highly lethal hemorrhagic disease among pigs, and ASFV's extreme antigenic diversity hinders vaccine development. We show that p72 ASFV phylogenetic analysis does not accurately define ASFV hemadsorption inhibition assay serogroups. Thus, conventional ASFV genotyping cannot discriminate between viruses of different virulence or predict efficacy of a speci...

Guidelines for the cost-effective prevention and control of African swine fever

Genetic diversity of East African Pigs: Implications for African Swine Fever (ASF)

African swine fever (ASF) is a viral hemorrhagic disease of pigs that results in complete mortality of infected animals, especially when improved genetics from the developed world are used. The virus is reportedly maintained in a sylvatic cycle that includes warthogs (Phacochoerus spp.) and bush pigs (Potamchoerus porcus) in Africa (Oura et al., 1998). There have been indications that ticks of ...

Development of the Multiplex PCR for Detection of the DNA-Contained Emergent Diseases Agents in Pigs (African Swine Fever, Aujeszky Disease, Circoviral Disease)

Introduction African swine fever virus (ASFV), pseudorabies virus (Aujrszky’s disease virus, ADV) and porcine circovirus type 2 (PCV-2) are some of the most dangerous DNA viruses causing high amounts of morbidity and mortality in commercial and backyard pig farms. Traditional diagnosis of porcine viral infections requires complex and lengthy combinations of virological and serological tests. Th...
