Reviewer Information: Christie Grueser received her undergraduate degree from the University of Colorado and her Masters in Communication from the University of Denver. For 14 years, she served as the Assistant Program Director and Microbiology Instructor for the Medical Technology Program at the University of Colorado School of Medicine.
Together with Dr. Elmer Koneman she has authored several educational software programs in clinical microbiology including: GermWare Mycology, GermWare Bacteriology and GermWare Parasitology, didactic and laboratory courses in Clinical Parasitology and Mycology, and most recently Image Atlases and Identification Guides for Clinical Bacteriology, Mycology and Parasitology as well as the Clinical Microbiology Question Bank. She currently provides workshops and webinars for the Denver Health Prevention and Training Center, funded by a grant from the CDC.
Course Description: This course addresses the significance of medically important arthropods and includes preanalytical, analytical, and postanalytical phases of handling ectoparasites in the clinical laboratory. Other topics, such as myiasis, illusory parasitosis, and handling of artifacts are discussed. Quality control and quality assurance as they pertain to arthropod identification are also addressed.
