2. Dipylidium caninum is a tapeworm that commonly infects dogs, cats and occasionally affects humans. The first cases of Dipylidium caninum in humans were discovered in 1903 with several cases in Europe and one in U.S Common names : dog or cat tapeworm, double – pored – dog tapeworm, cucumber seed tapeworm, flea tapeworm. Widespread intestinal parasite Dipylidiasis Intermediate host - Flea Hosts : dogs, cats and humans. Incubation period : approximately 20 days. Life cycle – dumb egg  playful child  wise adult

3. The length of tapeworm is 10 – 70 cm. Scolex – conical shape and has four suckers. There is a rostellum armed with several rings of hooks (15 – 30hooks). Segments( Stroblia ) – they contain two sets of male and female reproductive organs (hermaphrodite segments). They demonstrate two genital pores that lead to their name as the “double-pored”. Gravid segments – contains egg capsules. The number of eggs can range from 5 to 30. The larvae of Diphylidium caninum are know as cysticercoids because the scolex is enclosed in a fluid-filled cyst at this stage.

4. Human infection – rare Asymptomatic Infection causes abdominal pain, diarrhea and anal itch. Diagnosis – examination of stool for characteristic segments and eggs capsule. Treatment - Treatment for both animals and humans is simple and very effective.  A prescription drug called praziquantel is given, either orally or by injection (pets only). The medication causes the tapeworm to dissolve within the intestine.
