ABSTRACT
taenia pisiformis Rabbit tapeworm. Dogs acquire infection by eating rabbit viscera. PPP= 2 months. Dx: Find segments (500 to 1000 µm long) or taeniid eggs (30 to 35 µm long) in feces. Segment recognized by rectangular appearance with single lateral reproductive pore. Can tease apart segment to reveal typical eggs. Adult Habitat: Small intestine. Similar Species: Dogs are host to other Taenia spp. (T. ovis, T. multiceps, etc.), but the segments can only be identified by experts and no way to tell eggs apart. Other tapeworm segments that can be found in dog feces: Dipylidium caninum (reproductive pores on each side of segment), and Spirometra, Diphyllobothrium, and Mesocestoides which all have medial pore on each segment, so it appears as though they do not have a pore unless one looks quite carefully. The eggs of Taenia are indistinguishable from those of Echinococcus. Range: World. Clinical Signs: Assymptomatic. Tx: Effective approved products:
