a
Also included in this table are clinically important revisions that were not addressed in Simner (2).
b
The term “diphyllobothriasis” may be used when the specific genus is not known.
c
We suggest reporting as “Diphyllobothrium/Dibothriocephalus/Adenocephalus” for morphologically consistent parasites when advanced morphological or molecular analysis is not available.
