Is Mycobacterium prabini a distinct species?

the ML tree. The lowest genetic distance was between M. bleekeri and M. albolineatus (6. 7%), while the highest genetic distance was between M. dibrugarensis and M. vittatus (22. 1%). The K2P distance between M. prabini and M. dibrugarensis is 21. 1%. These data add confidence to our recognition of M. prabini as a distinct species.

Can Mycobacterium marinum cause tuberculosis in fish?

In fact, mycobacterium marinum causes tuberculosis-like disease in fish and frogs. Like mycobacterium tuberculosis, mycobacterium marinum can survive inside host cells and is proposed as a model to study mycobacterium tuberculosis.

How is Mycobacterium marinum treated?

Mycobacterium marinum is a multi-drug-resistant organism and is often best treated with combinations of two or three anti-mycobacterial drugs. Mycobacterium marinum is susceptible to anti-mycobacterial drugs, including clarithromycin, rifampin, ethambutol, minocycline and trimethoprim-salfamethoxazole.

What is the pathophysiology of Mycobacterium marinum tuberculosis (mm)?

Mycobacterium marinum infection of adult zebrafish causes caseating granulomatous tuberculosis and is moderated by adaptive immunity. [Infect Immun. 2006] Mycobacterium marinum infection of adult zebrafish causes caseating granulomatous tuberculosis and is moderated by adaptive immunity.

How is Mycobacterium marinum diagnosed?

The diagnosis is made by history, a consistent appearance of the lesion, and biopsy and culture. Mycobacterium marinum grows best at low temperatures, and culture at 28 to 30°C (rather than 37°C) is required for optimal isolation.

What is mycobacteria?

Is Mycobacterium marinum a risk factor for tuberculosis?

Among nontuberculous mycobacteria (NTM), it is the leading cause of extrarespiratory human infections worldwide. In addition, there is a specific scientific interest in M. marinum because of its genetic relatedness to Mycobacterium tuberculosis and because experimental infection of M. marinum in fishes mimics tuberculosis pathogenesis.

How do you test for Mycobacterium in fish?
