Studies of influenza virus infection in the chick embryo using fluorescent antibody.
As evidenced by specific staining with fluorescent antibody, the major sites of multiplication of the PR8 and Lee B strains of influenza virus in chick embryos injected by the amniotic route were in the cells lining the amnion and in the epidermal and pharyngeal epithelium. Varying amounts of virus were also present in the epithelium of the allantois and less frequently in the peritoneum. No virus was detectable in any of the other tissues of 25 embryos injected between the 7th and 11th days of incubation and examined 48 hours later. Three out of five of the embryos inoculated with the PR8 str
