Reviewer Information: Hallee Waye, MS, MLS (ASCP)CM, has over 10 years of experience as a medical laboratory scientist. She has clinical experience in blood bank, microbiology, chemistry, hematology, urinalysis, and coagulation. She currently works as a clinical microbiologist and MLS Program Director for the Parkview School of Medical Laboratory Science in Pueblo, Colorado. She obtained her bachelor’s degree in microbiology from Colorado State University, attended the Colorado Center for Medical Laboratory Science to obtain her professional certificate in medical laboratory science, and completed her master’s degree in clinical laboratory science at the University of Texas Rio Grande Valley.
Course Description: This course provides a basic understanding of medically important anaerobic bacteria. Clinical significance, general characteristics, and culture growth requirements are explained. The types of acceptable patient specimens, proper specimen collection procedures, media, and special conditions/handling are described. In addition, basic Gram stain reaction and significant differences between several commonly encountered anaerobes are explained. The identification and susceptibility testing methods for medically important anaerobic bacteria are compared and contrasted.
