We conducted a serologic investigation of porcine reproductive and respiratory syndrome virus (PRRSV) in hybrid wild boar herds in China during 2008–2009. PRRSV isolates with novel genetic markers were recovered. Experimental infection of pigs indicated that hybrid wild boars are involved in the epidemiology of PRRSV.
Hybrid wild boars, also known as special wild pigs in China, are a hybrid animal with 75% wild boar lineage and 25% domestic Duroc pig lineage. Hybrid wild boars are genetically stable and retain the appearance of wild boars. In addition, they have less body fat, are strongly adaptable to various environments, and have an estrus cycle in all 4 seasons.
We observed an increased incidence of high fever and respiratory disorders in hybrid wild boars. This illness resulted in increased economic losses in Shandong Province, China. We conducted a serologic study and identified highly pathogenic porcine reproductive and respiratory syndrome virus (PRRSV) in affected hybrid wild boars.
