Blood from 48 chicks was examined for anemia (packed cell volume), and plasma was examined for virus particles by direct transmission electron microscopy (DTEM). There was agreement between the occurrence of anemia and the presence of CAA virus particles in plasma from anemic chicks (Kappa = 0.2425, Z = 2.096, P = 0.036). Although DTEM is a method that can be used to diagnose CAA in chicks, more sensitive, economical and less laborious diagnostic assays are needed.
