Additional Information
Level of instruction: Basic to intermediate
Intended audience: Medical laboratory scientists, medical laboratory
technicians, laboratory supervisors, and laboratory managers. This course is
also appropriate for MLS and MLT students and pathology residents.
Course Description: This course introduces the reader to the different organisms responsible for malarial disease. The life cycles of the malaria-causing organisms and the transmission vectors are discussed in detail, as are the clinical manifestations for each type of infection. The course also presents the current and emerging diagnosis techniques and treatment options for malarial disease.
