The MICROBIOLOGIST 1 provides accurate and timely detection and identification of microbial populations, contaminants, microbial infections, or genetic abnormalities through the microscopic examination and analysis of environmental agricultural and biological samples. Employees in this class perform standard tests and procedures whose results may require standard interpretations or correlation's with other tests.


This is the first level of a three-level series. The emphasis of this class is on performing standard microbiological tests and procedures on a production basis. It is distinguished from the higher level by the absence of performing technically complex tests and procedures whose results require more than routine interpretation and correlation with other tests. At this level, employees generally do not exercise independent scientific judgment in the interpretation of data nor make recommendations on the application of the findings. Employees in this class may, under close supervision of a higher level microbiologist, perform analyses requiring complex analytical techniques.


Allocation of positions to this class will depend on the total work performed which may include one or a combination of the duties or tasks listed below.

  1. Benchwork. Typical tasks: logs in sample or specimen noting date, time, and tests to be performed; prepares necessary equipment and organizes supplies, media, and reagents; prepares sample or specimen for testing by diluting, filtrating, staining, or centrifuging; performs standard microbiological tests such as: aerobic plate count, coliform, antibiotic residue, serum neutralization, and agglutination; runs quality control samples with known values to determine if procedure and results are within acceptable limits; calculates numerical results based on quantitative growth patterns.
  2. Reports. Typical tasks: enters results of test in log book or computer; completes test result form to be sent to person or agency that submitted specimen or sample and notifies supervisor immediately in cases of significant positive test results; completes daily and monthly reports including number and types of tests performed and number of positive findings; maintains accurate and up-to-date records detailing quality control procedures used in all tests.
  3. Miscellaneous. Typical tasks: calibrates, troubleshoots, and performs minor maintenance to laboratory equipment; takes inventory and requisitions supplies with supervisor's approval; testifies on methodology and results of tests when those results are evidence in cases of litigation; keeps current in field by reading literature and attending symposia and workshops; maintains knowledge of all areas of laboratory by rotating duties with microbiologists in other sections.


Employees in this class have daily in-person or telephone contact with agency staff to exchange information or discuss test results. They have occasional contact by phone with county health departments, physicians, industrial and business representatives, and other agencies to discuss issues pertaining to a sample or specimen.


Employees in this class work under general supervision of a laboratory supervisor or other administrative superior. Test data, results, and any standard interpretation are reviewed routinely for accuracy and precision. Reports are reviewed for completeness and accuracy. Records are reviewed routinely for quality control. Guidelines used in performance of duties include standardized testing procedures, accepted aseptic and sterilization procedures, established laboratory procedures, and applicable State and Federal regulations.


  • A Bachelor's degree with advanced courses in Bacteriology, Chemistry, and/or other biological fields which shows knowledge of microbiology theory, principles, and practices and laboratory procedures, equipment, and instruments; OR  
  • An equivalent combination of training and experience.
