Canine distemper viral inclusions in blood cells of four vaccinated dogs.
Four cases of canine distemper were detected by the presence of numerous cytoplasmic inclusions in various circulating blood cells. Fluorescent antibody techniques and electron microscopy confirmed the identity of the viral inclusions. The cases occurred in the same geographic area and within a short time span. All four dogs had been vaccinated against canine distemper, but stress or other factors may have compromised their immune status. The possibility of an unusually virulent virus strain was also considered.
