Microbiology testing involves the isolation, identification, and enumeration of microorganisms in any given sample.

Microorganisms are ubiquitous in nature and are an integral part of our daily lives. Did you know that microorganisms can have both beneficial and harmful impacts on human health and environment. 

Many of them contribute to important bodily processes such as the development of a strong immune system, proper digestion, vitamin K production, protection against infections, and detoxification processes. While many microorganisms are used in the large-scale production of alcoholic drinks, yogurts, cheese, probiotics, drugs, and so on.

While there are many pathogenic microorganisms that lead to serious infections or diseases in the human body. The major problem is microbial infections can be transmitted easily through contact with contaminated surfaces, unclean hands, droplets, and aerosols. Hence, microbiological testing plays a crucial role in the identification and characterization of pathogenic microorganisms, which subsequently help in reducing the burden of microbial infections.

Examples of Microbial Threats

The persistence of microbial infection has become a major threat to public health. Additionally, increased microbial drug resistance is causing more serious health hazards including mortality. Some of the major microbial threats may include –

  • MRSA (Methicillin-resistant Staphylococcus aureus) infections
  • Neisseria meningitidis
  • Mycobacterium tuberculosis
  • Pseudomonas aeruginosa
  • Human immunodeficiency virus (HIV)
  • Severe acute respiratory syndrome coronavirus 2
  • Candida albicans

Industries That Require Microbiology Testing

Microbial testing is very important for the identification of pathogens from contaminants and the evaluation of the efficacy of antimicrobial-treated products. A majority of industries require microbial testing such as –

  • Food industry

Foodborne infections are still a major concern all over the world today. Microbiology food testing helps in the detection of food-borne pathogens and other microorganisms causing food spoilage.

  • Textile industry

Considering the concerns of customers for microbial infections and associated health hazards, textile industries are betrothed in making antimicrobial textiles. Such antimicrobial finishes inhibit the growth of pathogenic microbes when coming in contact with the surfaces. Antimicrobial testing is done to ensure the efficacy of antimicrobial textiles against a wide range of microorganisms. 

  • Healthcare facilities 

Cross contamination and nosocomial infections are major concerns among healthcare workers, doctors, and visitors in hospital settings. Hence, microbiology testing is very important to prevent or control the spread of infections.

  •  Diagnostic Microbiology laboratory

      It helps in the right diagnosis of pathogenic microorganisms responsible for infection or disease.

  • Disinfectant industry 

Disinfection practices are acknowledged as the first line of defense to avoid and control microbial contaminations. On the basis of the intended use of the disinfectant product, antimicrobial testing methods such as EN 1276, and EN 14476 are used to ensure efficacy claims.

  • Plastic industry

Plastic industry is another important area where microbial testing is very important. A lot of items made up of plastic are being used in everyday life. As per research studies, plastic surfaces allow the growth of infectious organisms, hence encouraging the spread of infections.
