Test type: Infections
Doctor: Physician, Gynecologist, Chest Physician, Neurologist
Test Department:
Pre Test Information: No special preparation required
Test Details:
The culture of Mycobacterium atypical, also known as non-tuberculous mycobacteria (NTM), is a laboratory test used to isolate and identify these bacteria from a clinical specimen. Here is an overview of the test:
- Specimen collection: The test requires a clinical specimen, which can include sputum, bronchoalveolar lavage fluid, tissue biopsy, or other body fluids. The specimen is collected using a sterile technique.
- Specimen processing: The collected specimen is processed in the laboratory to remove any contaminants and to concentrate the mycobacteria present. This may involve decontamination, homogenization, and centrifugation steps.
- Inoculation: The processed specimen is inoculated onto specific culture media that promote the growth of mycobacteria. The most commonly used media include Lowenstein-Jensen (LJ) agar and Middlebrook 7H10 or 7H11 agar. These media contain various nutrients and inhibitors to suppress the growth of other bacteria and fungi.
- Incubation: The inoculated culture plates are incubated at a specific temperature, usually 37°C, for several weeks. Mycobacteria, including NTM, grow slowly and require an extended incubation period for visible growth.
- Observation: The cultures are observed regularly for any signs of growth. Colonies of mycobacteria typically appear as small, rough, and often pigmented colonies. The growth characteristics, such as color, texture, and rate of growth, can help differentiate different species of NTM.
- Identification: Once the mycobacterial colonies have grown, further tests are performed to identify the specific species. This may include biochemical tests, molecular methods (such as polymerase chain reaction), and growth characteristics on specific media.
- Drug susceptibility testing (DST): In some cases, drug susceptibility testing is performed to determine the sensitivity of the isolated NTM to various antimicrobial agents. This helps guide the appropriate choice of antibiotics for treatment.
It is important to note that the culture of NTM requires specialized expertise and facilities, as the growth characteristics and identification methods differ from those used for Mycobacterium tuberculosis, the causative agent of tuberculosis.
