Experimental infection of warthog (Phacochoerus aethiopicus) with African swine fever virus

Abstract

Although there were no obvious signs of illness following experimental infection of young warthog with African swine fever virus, the animals developed viraemias between 10²'⁴ and 10³'⁶, HD₅₀/m within the first week of infection, and virus concentrations in a number of lymphatic tissues attained high levels ( =>10⁶ HD₅₀/g). Unlike in blood, and to some extent in the spleen, virus titres in lymph nodes did not decline appreciably during the 33-day observation period, since at the end of the period lymphatic tissues from 2 warthog were still infectious for domestic pigs to which these tissues were fed.
