DISEASE CONTROL
DIVISION
The primary mission of the Disease Control Division is to test human specimens, food and water for diseases of public health significance. Much of this testing is unique to the Hygienic Laboratory. The testing services help prevent the spread of disease in Iowa through the detection of infectious germs, newborn screening for genetic disorders and maternal screening.

Microbiology

Microbiology performs testing in several areas: bacteriology, parasitology, mycobacteriology and mycology. The section isolates, identifies and characterizes pathogens, and performs confirmatory testing of suspect agents of bioterrorism. The Hygienic Laboratory is the only laboratory in Iowa that performs many specialized public health tests such as enteric organisms serotyping, rabies testing associated with human exposure, and Pulsed Field Gel Electrophoresis as a member of the CDC’s PulseNet program.

PulseNet connects foodborne illness cases by DNA “fingerprinting” of the bacteria to detect and define local and multi-state foodborne outbreaks. The Hygienic Laboratory is also a member of the Laboratory Response Network, which responds quickly to biological, chemical and radiological threats and other high priority public health emergencies.

Major achievements:

  • Participated in CDC and APHL specialized methodological training to enhance testing capabilities, especially for the Laboratory Response Network.
  • Acquired a MALDI-TOF instrument, which will improve the speed and accuracy of identification of clinical isolates. This technology has been validated for use in rapidly identifying mycobacterial and fungal organisms.
  • The Hygienic Laboratory became the only facility in Iowa certified to perform the CDC Ebola assay in support of patient testing and treatment.
