This summer, Berea College students conducted research at Berea College under the mentorship of Dr. Ron Rosen. The research that they performed was about factors that might lead to the observed lower intensities of infection of the Leuceruthrus micropteri, compared to Proterometra macrostoma, in their centrarchid fish definitive hosts. They collected samples at North Elkhorn creek, and then brought them back to the lab to experiment. When the cercaria freshly emerged, they put them in cold-blooded saline of different pH. The cercariae L. micropteri did not emerge from without pepsin in 2.0 and 2.5 pH. These results may partly explain the lower intensities of infection observed in centrarchid fish with L. micropteri when compared to P. macrostoma.
