How microbiological testing laboratories help in the prevention and control of infection?

Posted by Anthony Lewis on April 30th, 2021

A microbiological testing laboratory is a facility that is dedicated to test for, culture, and detect the presence of microorganisms and pathogens, such as viruses, bacteria, yeasts, fungi, and other harmful substances.

Run by a team of dedicated and skillful professionals who have proper training and educational qualifications, they play a key role in the control and prevention of infection and diseases by detecting the presence of harmful pathogens and substances in food, water, and surfaces of residential or working places.

That’s the reason behind the impressive growth of the microbiological testing laboratory market all over the world. As per a report by Data Bridge Market Research, the global microbiology testing market is projected to grow at a CAGR of 8.13% and touch almost US billion by 2027.

How microbiological testing works?

Microbiological testing entails biological, chemical, or biochemical methods for examining and detecting microorganisms present in it. The testing process includes sampling filtering, culturing, and incubating processes to render final results. The processes also assist in detailing the number of contaminants in a given sample.

What are the techniques followed by a microbiological testing laboratory to identify microorganisms?

These are the following techniques followed by a microbiological testing laboratory to identify microorganisms and pathogens:

1. Using microscope: A good microbiological testing laboratory uses sophisticated microscopes, including electron microscopes, to identify microorganisms and pathogens.

2. Biochemical tests: These are done to differentiate between different types of bacteria based on their enzymatic activities. Some common biochemical tests include Catalase tests, Dnase tests, Indole tests, oxidase tests, etc.

3. Microbial serology: This is a microbiology laboratory test that is conducted to find out bacterial and viral antibodies and antigens to assist in the diagnosis of specific diseases and check immune status. There are different types of serological tests including Western blotting, neutralization tests, agglutination, and direct and indirect immunofluorescence.

4. Molecular analysis: This is a more sensitive, rapid, and less laborious testing technique as compared to other methods and is employed to identify, classify, and/or characterize several types of microorganisms.

5. Motility and staining: Under this technique, the motility capacity of a microbe is determined to distinguish it from others. The staining technique is used to detect microorganisms through their cell properties.

How microbiology testing laboratories prevent contamination?

A microbiology testing laboratory prevents contamination through the following techniques:

1. Sterilization: Under this decontamination technique, microorganisms and their spores, such as viruses, bacteria, and prions, are killed. This is normally carried through chemical methods or physical methods such as filtration or using radiation and/or heat.

2. Sanitization: Under this technique, bacteria, pathogens, and non-pathogenic microorganisms are eliminated before they further multiply on any surface. A wide array of chemicals and products are used for the process, including hydrogen peroxide, formaldehyde, alcohol-based cleaners, and chlorine-based cleaners.

3. Disinfection: This decontamination technique is used to prevent or reduce the growth of bacteria, pathogens, and non-pathogenic microorganisms from surfaces or objects. Disinfectants like chlorine, alcohol, etc, are used to make the surface and substance infection-free.

4. Aseptic technique: This technique is performed under sterile conditions to check the introduction of bacteria, pathogens, microorganisms, or other contaminants into an environment. This key technique is used to prevent any contamination of laboratory cultures, personnel, and equipment.

Good Microbiological Practice (GMP)

It consists of techniques and practices while handling microorganisms that are extremely important to avert any contamination of the laboratory. This uses microbiology laboratory procedures or techniques for the safekeeping of microorganisms and other test materials as well as the safety of people who are inside the laboratory or facility. The main objective of GMP is to determine the outcome of the tests and research without adulterating or contaminating anything.

Biosan Laboratories, founded in 1973, provides highly specialized microbiological laboratory testing services in legionella laboratory testing, antimicrobial testing, microbiological testing, as well as manufactures bacteria test kits.
