Which drugs are effective against Mycobacterium species?

Which drugs are effective against Mycobacterium species?

Tigecycline, tobramycin, clarithromycin, and amikacin were most effective at broad inhibition of rapid-growing mycobacteria; whereas, amikacin, clarithromycin, and rifampin were effective at inhibiting all slow-growing M. marinum strains tested.

What kills Mycobacterium Marinum?

The gold standard for treatment of infection by M. marinum is oral antibiotics. Clarithromycin with ethambutol is currently the preferred antibiotic selection. Rifampin is typically added to the antibiotics regimen if deeper organ infection is present, such as bone infection (osteomyelitis).

What media is used for Mycobacterium?

Löwenstein–Jensen medium, more commonly known as LJ medium, is a growth medium specially used for culture of Mycobacterium species, notably Mycobacterium tuberculosis. When grown on LJ medium, M. tuberculosis appears as brown, granular colonies (sometimes called “buff, rough and tough”).

Is Mycobacterium antibiotic resistant?

Mycobacterium tuberculosis is intrinsically resistant to many antibiotics, limiting the number of compounds available for treatment. This intrinsic resistance is due to a number of mechanisms including a thick, waxy, hydrophobic cell envelope and the presence of drug degrading and modifying enzymes.

Can Mycobacterium tuberculosis be treated with antibiotics?

Treatment for tuberculosis (TB) usually involves taking antibiotics for several months. While TB is a serious condition that can be fatal if left untreated, deaths are rare if treatment is completed.

Which of the following is effective against mycobacteria?

A naturally occurring antibiotic called kanglemycin A is effective against Mycobacterium tuberculosis, the bacteria that cause tuberculosis, even in drug-resistant strains, according to an international team of researchers who used chemistry, molecular biology, microbiology, and X-ray crystallography to show how the …

Which drug is effective against Mycobacterium tuberculosis and Mycobacterium leprae?

Nitazoxanide (NTZ) is an anti-parasitic drug that also has activity against bacteria, including Mycobacterium tuberculosis. Our data using both radiorespirometry and live-dead staining in vitro demonstrate that NTZ similarly has bactericidal against M. leprae.

How can you prevent Mycobacterium Marinum?


  1. Minimize or eliminate exposure to fresh or salt water when open cuts, scrapes or abrasions exist on the skin.
  2. Be sure to cover any open cuts, scrapes or abrasions, and wear heavy or waterproof gloves when cleaning fish, fish tanks or equipment.

Does Mycobacterium grow on MacConkey Agar?

Recent evaluations of the MacConkey agar test for differentiation of rapidly growing mycobacteria have revealed that certain strains of Mycobacterium fortuitum and M. Investigation of two formulations of MacConkey agar showed that these two species grew better on the medium when the crystal violet dye was omitted.

What agar does Mycobacterium tuberculosis grow on?

tuberculosis grows easily on blood agar within 1to 2 weeks, indicating that this basic medium is suitable for laboratory diagnosis of tuberculosis in addition to other media.
