a Photomicrograph (×400) and (b) electron micrograph (×950) of FARM recovered by lavage of the chicken respiratory system. The cells have eccentric nucleus (N) and plasma membrane ruffled with filopodial extensions (arrows). In (b), numerous cytoplasmic vesicular bodies presumed to be lysosomes (red arrows) were identified. The Semithin (1 μm) and the ultrathin (80 nm) sections were cut from processed blocks of epoxy resin embedded cell suspensions
