Abstract

The replication of Pseudorabies virus (PRV) in cultured swine alveolar macrophages (AM) was studied using 6 different virus strains. AM were highly permissive to PRV infection, with progeny virus titres of 10⁷ TCID₅₀/ml from some strains. Virus progeny titres were higher in cultures infected with the field strains S-62 and 4892 than in cultures infected with the strains Bartha or PRV-C. Virus replication, viral DNA synthesis and the concomitant cell damage were dependent upon virus input m.o.i.s. and virus strain. Furthermore, cells from 7 day old pigs yielded higher virus progeny titres than cells of 6 week old pigs. The results from this study provide support to the premise that PRV infection may predispose anials to respiratory disease.
