Mycobacterium abscessus subsp. abscessus strain 417

Mycobacterium abscessus subsp. abscessus strain 417 is a rod-shaped bacterium known to inhabit chloraminated water sources. This strain possesses true flagella, which may contribute to its motility and ability to colonize various environments. It is characterized by having a single replicon, indicating a streamlined genomic organization. This organism has a wide host range, affecting Homo sapiens as well as various metazoans, including Aves, Phocidae (seals), Rodentia, and Panthera leo (lions). The health effects associated with M. abscessus strain 417 are significant, as it is linked to a range of serious conditions. These include endocarditis, peritonitis, and various lung infections such as pulmonary disease, non-cavitary pneumonia, and chronic pulmonary infections. The strain can also cause cervical lymphadenitis, skin infections, localized lesions, and disseminated infections, highlighting its potential to cause both localized and systemic diseases. The presence of M. abscessus in chloraminated water suggests that water systems may serve as reservoirs for this pathogen, posing a risk for human health and animal hosts alike. The bacterium's ability to cause a broad spectrum of infections underscores its clinical significance, particularly in immunocompromised individuals or those undergoing procedures such as peritoneal dialysis, where it can lead to PD-associated peritonitis. Understanding the ecological niches and pathogenic potential of M. abscessus strain 417 is essential for public health surveillance and developing strategies to mitigate its impact.
