Viruses, macrophage cell cultures, infection, mRNA labeling, and hybridization.
ASFV Pr4 was isolated from ticks obtained from Kruger National Park,
Republic of South Africa, in 1996 (South Africa, Pretoriuskop/96/4) and has had
limited passages in swine macrophage cell cultures (1). Pr4 deletion mutant
Pr4△35, lacking six MGF360 and two MGF530 genes, was constructed as previously
described (54). Macrophage cell cultures were prepared as previously
described (19). Cultures were infected with the Pr4 and Pr4△35 viruses at an
MOI of 10. A virus-depleted, Pr4△35-infected culture supernatant was prepared
to determine if viral infection is required for induction of the macrophage
transcriptional response (MOI of 0.0004). Virus was removed by filtration
through a 0.4-μm-pore-size filter, followed by a 0.1-μm-pore-size low-proteinbinding
filter (Millipore) (prefiltration titer, 1.5*10的8次方; postfiltration titer, 2.9*10的2次方). At 3 and 6 hpi
