Detailed Guide for

Microbiologists in California

May also be called: Bacteriologists; Cell Biologists; Cytologists; Epidemiologists; Immunologists; Mycologists; Virologists

Specialties within this occupation include: Medical Microbiologists; Clinical Microbiologists; Veterinary Microbiologists; Certified Public Health Microbiologists; Environmental Microbiologists; Industrial Microbiologists; Agricultural Microbiologists

What Would I Do?

Microbiologists study the growth, characteristics, and effects of bacteria and other microorganisms to better understand their relation to human, plant, and animal health. They look for unwanted microorganisms in raw materials and in finished products. Microbiologists are responsible for maintaining accurate records of their studies and ensuring that company and regulatory quality standards are being met.

The nature of the work may vary considerably with the assignments. Some Microbiologists deal with specific kinds of microorganisms such as fungi, algae, viruses, and microparasites. Others are concerned with specific fields or areas of work such as immunology, serology, virology, physiology, genetics, taxonomy, and cytology.

The majority of Microbiologists are classified by the specific activity they perform.

Medical or Clinical Microbiologists work with physicians, dentists, and medical researchers to study the interactions between microorganisms and humans to determine how and why diseases occur. They perform laboratory tests to provide information for diagnosis and treatment.

Veterinary Microbiologists are certified veterinarians. They study the interactions between microorganisms and animals to determine how and why diseases occur.

Certified Public Health Microbiologists provide laboratory services for local health departments and community environmental health programs. They are primarily concerned with the control of communicable diseases and other health hazards in the community.

Environmental Microbiologists test water samples from lakes and streams for biological and chemical pollutants as well as inspect food and water in processing plants.

Industrial Microbiologists are concerned with the development of new products and the monitoring of established processes for microbial content. They teach and develop new methods of preservation for food and pharmaceutical supplies and may help set quality standards for these products. These professionals may also tend strains of microorganisms that produce alternate sources of energy.

Agricultural Microbiologists study the effect of microorganisms on soil and agricultural products and the use of microorganisms as agents of insect control. They are concerned with methods to combat crop damage and increase crop yield. They also investigate the nutritional role played by microorganisms found in cattle, sheep, and other ruminants. They investigate the growth, structure, development, and other characteristics of microscopic organisms, such as bacteria, algae, or fungi.

Microbiologists use microscopes and other laboratory equipment to examine the physiological, morphological, and cultural characteristics of microorganisms in humans, water, food, and plants. They research, identify, and classify these microorganisms to develop products such as vitamins, antibiotics, amino acids, grain alcohol, sugars, and polymers. They conduct experiments, often with minimal guidance, by operating and maintaining laboratory equipment and working according to good laboratory procedures (GLP) safety guidelines.

Microbiologists perform activities related to cell harvesting, downstream processing, and product recovery or isolation. During both research studies and the manufacturing process, they must screen for any novel organisms and activities. In addition to documenting the progress of their experiments and findings, they write and execute technical studies.

Working Conditions

Microbiologists perform most of their work in comfortable laboratories and offices. Laboratory settings are sterilized and kept very clean to avoid contamination of cultures and culture media. Research work may also be done in the field, in a variety of environments, and under any weather condition.

Precautions must be taken in handling potent chemicals, animals, or disease-producing organisms. However, risks are minimized by using protective clothing, immunization, use of safety equipment, and adherence to safety rules and regulations. Strict adherence to safety protocols is essential when working with contagious or deadly microorganisms, such as those which cause AIDS, Ebola, Hantavirus, and other diseases for which cures are difficult or impossible.

Microbiologists normally work a 40-hour workweek. However, some employers such as public health and hospital laboratories require overtime and occasional weekend work. Hospitals and laboratories usually rotate their shifts. Weekend work and long hours may also be necessary during critical periods in the food and wine industries. University and college faculty may work only the number of months required by their contract.

Clinical Microbiologists who work in a hospital setting may belong to a union. Workers for local or State government may also belong to a union. Microbiologists may become members of the American Society for Microbiology.

Will This Job Fit Me?

The job of Microbiologist may appeal to those who enjoy activities that involve working with ideas and that require an extensive amount of thinking, searching for facts, and figuring out problems. Results-oriented individuals who are independent workers and like to make their own decisions should enjoy this type of job.

Microbiologists must be able to communicate with research team members and production staff at all levels. They must also be flexible, ready to change direction quickly during an experiment as situations change.

How Do I Qualify?

Education, Training, and Other Requirements

The minimum educational requirement for entry-level jobs is a bachelor's degree in microbiology, biology, or the equivalent. However, an associate of arts degree qualifies an individual to become a laboratory assistant or technician. A master’s or doctoral degree is necessary for college teaching, independent research, and administrative jobs. The level of responsibility and type of work performed determines the degree required.

In order to do microbiology testing of human samples, Microbiologists must be licensed with the California Department of Public Health (CDPH). Personnel who are not licensed or certified may work in federally funded nonprofit laboratories, academic institutions engaged in teaching or research, California licensed community clinics, private physicians’ offices, and some departments of State government.

Continuing Education

Continuing education is required for both the Clinical Microbiologist Scientist and those with limited licenses in microbiology. Continuing education information can be obtained from the CDPH.

Licensing and Certification

Microbiologists may be required to obtain a Clinical Laboratory Scientist license. With this license, they can work as a Clinical Microbiologist Scientist. Others may obtain a specialty (limited) license of Microbiology. Both of these licenses are issued by the CDPH.

A combination of academic coursework and suitable experience in a clinical or public health laboratory is required for an individual to qualify for a Public Health Microbiologist’s license, which is also issued by the CDPH. The usual pattern is a degree in one of the clinical laboratory sciences and one year of supervised training or internship in a clinical laboratory, or six months training in an approved public health laboratory. A person qualified academically but without training or experience is eligible for a trainee license. The trainee works under direct supervision and is tested periodically to verify they are learning at an acceptable pace.
Contact the agency that issues the license for additional information. Click on the license title below for details.

Public Health Microbiologists who work for the State of California or in local public health laboratories must posses a valid Public Health Microbiologist Certificate issued by the CDPH. Those who test milk for county health departments must obtain a Proficiency Certificate from the California Department of Food and Agriculture.

Additional certificates for Microbiologists include: Registered Microbiologist, Specialist Microbiologist, and Technologist in Microbiology. Those who specialize in Veterinary Microbiology may earn a Diplomate in Veterinary Microbiology. Those who specialize in Environmental Microbiology may earn an Environmental Microbiology Analyst certificate.
