title: Giardia trophozoites in dog hookworm, Ancylostoma caninum: accident or hyperparasitism?
abstract: During the course of transmission electron microscopic studies of adult Ancylostoma caninum removed from a dog, several Giardia trophozoites were found in sections of the buccal cavity, oesophagus and intestine of several hookworms. Although the protozoa appeared viable, this unusual finding probably represents accidental uptake by, rather than an established infection of, the hookworm. It is feasible, however, that the trophozoites might have survived and even multiplied in this aberrant site.
