Public Health Microbiologist Job Description

Controlling epidemics and pandemics is of the utmost priority for public health microbiologists. A public health microbiologist contributes to the prevention of communicable diseases, such as tuberculosis, plague, diphtheria, rabies, foodborne illnesses and sexually transmitted diseases, by observing and researching the relationships between microorganisms, diseases and public health. They may trace the origins of outbreaks or monitor prevalence and spread of diseases already endemic in a community, whether the diseases are spread from person to person or from animals to humans.

Public health microbiologists often work for a government health department, and may work under the supervision of the department's senior public health microbiologist. Public health microbiologists for local or state departments typically need a bachelor's degree in biology or microbiology, but graduate or even postdoctoral study in microbiology may be required for advanced positions. The abilities to interpret and analyze data, as well as understand and draw conclusions about issues that pertain to public health, are essential to become a successful public health microbiologist.

Job Duties of a Public Health Microbiologist

Public health microbiologists use a wide variety of laboratory techniques and are responsible for the day-to-day operation and maintenance of laboratory equipment used to perform tests for communicable diseases. They must record test results and maintain highly accurate records for research. Part of this research includes the study of how certain bacteria grow, develop, spread and react to antibiotics; other research may focus on viruses, mycobacteria, parasites or blood antibodies. Public health microbiologists may also test animals or animal remains for pathogens that can spread rabies, Lyme disease, West Nile Virus or other diseases to humans.

Microbiologists are also expected to comply with all federal, state and local laws that apply to public health laboratories. Individual state departments of public health offer various training opportunities for public health microbiologists, and most require certification.
