Honors College Theses

This study focused on the survey of 34 freshwater snail samples collected from NE Mongolia for larval flatworm parasites in the class Trematoda. 32 of the snail samples were infected, and the parasites were identified based on morphology and DNA sequences. Nine of the identified parasite samples were screened for the presence of bacterial endosymbionts in the genus Neorickettsia in the family Anaplasmataceae. All of the samples screened for Neorickettsia were negative for the bacterium. Species of Neorickettsia are known to cause several diseases such as Sennetsu Fever (in humans) and Potomac Horse Fever. There have been relatively few reliable …
