The Salary of a Medical Microbiologist

A medical microbiologist works almost exclusively in a laboratory.

A medical microbiologist specializes in the study of microorganisms, such as viruses, bacteria, fungi, algae and protozoa, and their potential effect and application in the medical setting. She seeks to gain knowledge about these organisms at both the molecular and cellular level, as well as studying their ecology. An important part of a microbiologist's role is to apply the knowledge she gleans to practical problems concerning medicine and disease, investigating how microorganisms can affect humans and how they might be useful to us.

Average Salary

In May 2009, the U.S. Bureau of Labor Statistics surveyed 16,260 microbiologists working in America, including medical microbiologists, and found that the mean annual salary for the profession was $71,980, equivalent to an hourly rate of $34.61. While the top 10 percent of earners in the field received an average of $113,150 per year, the bottom 10 percent were on an annual salary of $39,150.

The U.S. Bureau of Labor Statistics predicts that the job market for biological scientists, a classification that includes medical microbiologists, will grow by 21 percent through 2018, fuelled by an expansion in the biotechnology industry. As such, medical microbiologists should continue to receive competitive pay rates in the immediate future.
