Abstract
First-stage larvae of Crenosoma petrowi Morozov, 1939 from feces of black bears (Ursus americanus) developed to the third stage in the gastropod Mesodon thyroidus. In snails held at 23.5 °C, the first and second moults occurred on days 6–7 and 9–11, respectively, after infection. The prepatent period of C. petrowi was 19–25 days in five experimentally infected black bears. Both times of first and second moults and the prepatent periods are similar among species of Crenosoma. Crenosoma petrowi did not produce patent infections in, and no nematodes were recovered from, experimentally infected striped skunks (Mephitis mephitis), raccoons (Procyon lotor), or red foxes (Vulpes vulpes).
