Other Microbiology / Parasitology

Microbial pathogens include microscopic organisms such as bacteria, viruses, and
protozoans, as well as multicellular organisms such as helminths (worms) and other
parasites. Accurate microbial identification is critical for the optimal treatment of
patients presenting with infection. Laboratory tests are often essential for guiding
effective intervention. A wide range of testing options for infectious disease pathogens
is available and varies by organism. These include in vitro detection of an antibody or
antigen (serology), culture-based methods, and molecular assays that detect microbial
DNA or RNA. The types of organisms likely to cause infection can vary significantly with
geography. This section will address more prevalent microbial and parasitic infections.
