can cause autoreinfection by hatching in GI tract before they can hatch* - 8How is this organism diagnosed? (diagnostic stage) Taenia saginataEggs or proglottid in feces are diagnostic
If ova: report Taenia sp. (look identical)
If proglottid, look for numerous (15-30) thin uterine branches to differentiate - 9How is this organism diagnosed? (diagnostic stage) Taenia soliumEggs and/or proglottids in feces.
Eggs are indistinguishable from saginata
Speciate only if there is a proglottid with thicker uterine branches (7-13) - 10How is this organism diagnosed? (diagnostic stage) Diphyllobothrium latumEggs in feces are diagnostic.
