Infection of Oxydoras kneri by the acanthocephalan
Paracavisoma impudica is described. The parasites do not
penetrate deeply into the host gut wall and do not reach the
muscularis layers. Host reaction is minimal, consisting of
limited fibrosis around the proboscides. Haemorrhages and
lymphocyte infiltration are not observed, and phagocytic cells
are only present occasionally. Oxydoras kneri is a newly
reported host for Paracavisoma impudica.
