Insects and Parasite Interactions

Abstract Dipylidium caninum, the dog tapeworm, is a cosmopolitan parasite of dogs and cats and occasionally causes human infection in the United States. Diagnosis is made by observing the characteristic rice grain–like proglottids in stool specimens and the pathognomonic egg packets in the gravid uterus in histologic sections of the parasite. There have been few reported cases of human infection with this parasite, and very little information on the pathology of this zoonotic disease is available in the English language. This report of a case of D caninum infection in a 6-month-old infant highlights the diagnostic features of this disease. To our knowledge, this is the first case to be reported in the American pathology literature during the last 36 years (MEDLINE database, 1966–2002).
