The dwarf river crab Liberonautes latidactylus nanoides Cumberlidge & Sachs, 1989, from Liberia--a new second intermediate host of Paragonimus uterobilateralis.

Large populations of the dwarf river crab Liberonautes latidactylus nanoides Cumberlidge & Sachs, 1989, collected from the St. Paul river at the Haindi/Mauwa focus of paragonimiasis in Liberia were examined for parasitization by the human lung fluke, Paragonimus uterobilateralis. Four specimens out of 763 L.

Distribution of metacercariae in freshwater crabs in relation to Paragonimus infection of children in Liberia, West Africa.

An explanation was sought for the high prevalence of paragonimiasis in children in Liberia by examining possible modes of human infection from freshwater crabs. The occurrence, frequency of infection, and distribution of metacercariae of Paragonimus uterobilateralis in the freshwater crab Liberonautes latidactylus were studied. The muscles of the cephalothorax and of the legs were found to be the most frequently and most heavily infected parts of the crab.
