Human Dipylidiasis: A Case Report of Dipylidium caninum Infection from Karimnagar.

Abstract

Dipylidium caninum also refered to as the double-pored tapeworm is a cyclophyllidean cestode that commonly infects dogs and cats. Mammals act as definite hosts with intermediate hosts being dog and cat flea, the Ctenocephalides canis and Ctenocephalides catis respectively. The dog lice, Trichodectes canis and human flea (Pulex irritans) also transmit Dipylidium caninum infection. Infants and young children are at high risk of acquiring infection. Majority of the infections are due to close association with pet dog and cats. Humans are accidental hosts who acquire infection by ingestion of infected dog and cat fleas. We report a rare case of Dipylidium caninum infection in a 9 year old girl who could have acquired infection by consuming food contaminated with infected fleas.
