MEDT 471 Parasitology/Mycology

(3 SEMESTER HOURS)

This course involves two different modules that together constitute a comprehensive introduction to parasitic and fungal infections of humans with emphasis on the major pathogens encountered in the clinical laboratory.

In the didactic portion of the course, students are introduced to each taxonomic group of parasites and fungi where morphology, life cycles, clinical symptoms, disease, diagnosis, treatment, and epidemiology are discussed in detail.

In the laboratory portion of the course, the emphasis is on visual identification of pathogenic organisms.

In the Parasitology Module, students will view stained slides and/or numerous reference vials of organisms such as cestodes, trematodes, filarial/intestinal/tissue nematodes, protozoans, malarial parasites, as well as Babesia, Leishmania, Trypanosoma and Toxoplasma. Each student will be responsible for accurate and independent identification of two unknowns (one from a concentration procedure and one from a trichrome-stained slide).

In the Mycology Module, students will view a variety of yeast strains as well as lactophenol cotton blue–stained slides of pathogenic molds. Organisms such as Zygomycetes, Dermatophytes, Dematiaceous, Hyaline and Dimorphic fungi as well as Pneumocystis jiroveci will be examined. Students will be responsible for the accurate and independent identification to the genus and species level of one unknown organism.
