Mycobacterium abscessus is a type of bacteria that can cause infections in humans, particularly in those with weakened immune systems. There are several tests that can be used to diagnose an infection caused by this bacteria.

One common test is a culture and sensitivity test, which involves taking a sample from the infected area and growing it in a laboratory. The bacteria can then be identified and tested against different antibiotics to determine which ones are most effective in treating the infection.

Another test that may be used is a polymerase chain reaction (PCR) test, which detects genetic material from the bacteria in a sample. This test can be particularly useful for diagnosing infections that are difficult to culture or if a rapid diagnosis is needed.

Imaging tests such as X-rays, CT scans, and MRI scans may also be used to identify areas of infection and assess the extent of the damage.

It is important to note that recent research performed by senior author Maha Farhat, the Gilbert S. Omenn Associate Professor of Biomedical Informatics at HMS at Harvard Medical School and published May 22 in PNAS, suggests that the pathogen may not be that prone to person-to-person transmission after all.
