The role of wild hosts (wild pigs and ticks) in the epidemiology of African swine fever in West Africa and Madagascar.

摘要: African swine fever (ASF) adversely affects pig production in Sub-Saharan Africa. In southern and eastern Africa, the virus is maintained populations of wild pigs (Phacochoerus africanus) soft ticks from Genus Ornithodoros. The bushpig (Potamochoerus larvatus) has also been showed to be asymptomatically infected by virus. other parts continent such as West Africa or Madagascar, role suids not demonstrated. objectives this study were investigate existence a sylvatic cycle its potential impact on epidemiology ASF Senegal Madagascar. Samples Malagasy bushpigs Senegalese warthogs have collected areas interface between domestic where had reported analyzed for anti-ASF antibodies (ELISA)and viral DNA (PCR). Ticks farms near resting areas, their infection status with ASFV was determined using PCR. addition, sera tested anti-tick (ELISA). preliminary results obtained so far suggest that epidemiologic Madagascar does involve warthog-tick-domestic transmission described East South
