Test-Microbe: standard strain of microorganism for determining the activity of antibiotics and other bacteriostatic or bactericidal agents

In medicine and pharmacology, it is important to have a reliable way to determine the effectiveness of antibiotics and other bacteriostatic or bactericidal agents. To do this, use a standard strain of microorganism called Test-Microbe.

Test-Microbe is a standard strain of microorganism that is used to determine the activity of antibiotics, the effectiveness of disinfectants and other bacteriostatic or bactericidal agents. This strain was isolated in 1926 by scientist Edward L. Trailer and was named Staphylococcus aureus ATCC 25923.

Staphylococcus aureus is a Gram-positive coccus that is often found on the human skin and nasopharynx. Under normal conditions, it does not cause disease, but if the integrity of the skin is compromised, it can cause infections. This organism can also be resistant to many antibiotics, making it an ideal candidate for testing the effectiveness of antibiotics.

Test-Microbe is used to determine the minimum inhibitory concentration (MIC) of antibiotics. The MIC is the lowest concentration of an antibiotic that inhibits the growth of a microorganism. To determine the MIC, a serial dilution method is used, in which the antibiotic is diluted in a series of tubes with a nutrient medium, into each of which a certain number of bacteria is added. After incubation for several hours or days, it is determined in which tube the bacteria did not grow.

The Microbe Test is also used to evaluate the effectiveness of disinfectants and other bacteriostatic or bactericidal agents. To do this, a test is performed to determine the minimum bactericidal concentration (MBC), which is the lowest concentration of a disinfectant that kills all bacteria. This test is also performed using the serial dilution method.

Test-Microbe is an important tool in medicine and pharmacology for determining the effectiveness of antibiotics, disinfectants and other bacteriostatic or bactericidal agents. With this strain, you can quickly and reliably determine which antibiotic or disinfectant will be most effective in treating or preventing an infection.

Today we will talk about the microbe test. What is it and why is it needed?

A test microbe is a standard strain of an organism that is used to measure the activity of antimicrobial drugs. They are usually used in the healthcare sector. They help scientists determine the effectiveness of cleaning products in healthcare settings, monitor antibiotic use, and more. In addition, test microbes are used in laboratories to study and determine the spectrum of action of various antimicrobial drugs.

Testing for microbial activity can be done using a culture medium such as animal or human blood or urine. In this case, microorganisms that grow normally in a standard test or sample will serve as a reference point when testing the antimicrobial activity of various active substances. Once the necessary methods for storing and producing microorganisms have been implemented, testing is performed using blood plates made from special materials that mimic natural samples, and other methods such as bacterial growth testing in milliliter tubes or gas compaction tests can also be used. The number of test microbes for one test, depending on the type of test microbe and the selected testing method, can range from 1 to 40 times. The result is assessed as positive (statistically detectable increase or absence of microorganism growth) or negative. In general, the shelf life is 3-6 months due to the gradual decrease in the number of microorganisms.

The microbiological activity test is designed to test the antimicrobial effectiveness of a wide range of products such as conditioners, antiseptics, drugs, and even personal care products. Most tests do not take long, usually about an hour. Also, many of them provide results in just a few days or even days after you submit your sample. On the other hand, some types of tests may take several weeks to receive results.
