Nearly every life form is host to a parasite. This course emphasizes the hands-on study of parasites of invertebrate animals and marine fishes and incorporates field investigations and laboratory work. This course serves to integrate parasite diversity and life history, aspects of the ecology of parasitism, mechanisms of infection, epidemiology, host responses to infection, and pathology. Students will receive training in post-mortem examination, microscopy, parasite identification and diagnosis (morphological and molecular). Experience with experimental design, scientific writing, and data presentation will be acquired in association with independent student research projects. There may be an additional charge for field trips. Limited enrolment.
