Photochromogenic Mycobacterium

Several intermediate-growing, photochromogenic bacteria were isolated from sphagnum peat bogs in northern Minnesota, USA. Acid-fast staining and 16S rRNA gene sequence analysis placed these environmental isolates in the genus Mycobacterium, and colony morphologies and PCR restriction analysis patterns of the isolates were similar Gauthier et al.: Photochromogenic Mycobacterium spp. from Morone saxatilis growing mycobacteria (Tortoli 2003). Region B in - cludes helix 18 of the 16S rRNA molecule, and in - sertions within this region are, with exceptions, characteristic of slow-growing mycobacteria, while the presumably ancestral short helix is characteristic o

A large diversity of Mycobacterium spp. has been isolated from striped bass Morone saxatilis in Chesapeake Bay, USA. The new species M. shottsii and M. pseudoshottsii are the dominant isolates, while the classical fish pathogen M. marinum is found much less frequently. M. fortuitum and M. chelonae, other Mycobacterium spp. known to commonly infect fishes, have not yet been aseptically isolated. From Wikipedia, the free encyclopedia Mycobacterium is a genus of Actinobacteria, given its own family, the Mycobacteriaceae. Over 190 species are recognized in this genus. This genus includes pathogens known to cause serious diseases in mammals, including tuberculosis (Mycobacterium tuberculosis) and leprosy (Mycobacterium leprae) in humans Mycobacterium kansasii is a slowly growing photochromogenic mycobacterium (Figure 14). Mycobacterium kansasii is usually the second most common cause of NTM disease. Isolation of the bacteria in human specimens is almost always associated with disease. The major reservoir of the bacteria is likely to be tap water

'Mycobacterium sherrisii' is an undescribed species that appears to be emerging, in particular, among HIV-positive patients originating from Africa. To describe 'M. sherrisii', to ensure that the species name is validly published and to define its phylogenetic position, we collected 11 of these stra Rapid growing mycobacterium consists of organism of the Mycobacterium fortuitum group and Mycobacterium chelonae/Mycobacterium abscessus group and these usually cause subcutaneous abscesses or cellulitis following trauma in immunocompetent patients.: 340 •Mycobacterium aichiense. Photochromogenic This is a report on the analysis and treatment of 152 cases of pulmonary disease caused by photochromogenic mycobacteria of the type Mycobacterium kansasii-Group I of Runyon's classification.

Mycobacterium marinum is a photochromogenic, slowly growing (8-12 days) organism that optimally grows between 30 and 33 °C (Figure 16). Mycobacterium marinum is the causative agent of 'swimming pool' or 'fish tank granuloma' which is the result of finger, hand, arm, elbow, knee, or toe soft tissue injury in fresh or saltwater (puncture of fish, shrimp, or fins), fish tanks (cleaning. A strain isolated from a biopsy sample taken from a slowly spreading skin granulation on a child's hand was found to have properties consistent with its classification in the genus Mycobacterium... Mycobacterium marinum is a well-known pathogenic mycobacterium for skin and soft tissue infections and is associated with fishes and water. Among nontuberculous mycobacteria (NTM), it is the leading cause of extrarespiratory human infections worldwide.

SUMMARY Mycobacteria are the causative organisms for diseases such as tuberculosis (TB), leprosy, Buruli ulcer, and pulmonary nontuberculous mycobacterial disease, to name the most important ones. In 2015, globally, almost 10 million people developed TB, and almost half a million patients suffered from its multidrug-resistant form. In 2016, a total of 9,287 new TB cases were reported in the.

A rapidly growing pigmented mycobacterial strain with an ambiguous biochemical profile was isolated from the blood culture taken through the Hickman catheter of a 9-year-old girl with acute lymphoblastic leukemia. Whole-cell fatty acid analysis showed that the best match profile was that of Mycobacterium aurum, but the similarity index was only 0.217, meaning that there were no good matches. Mycobacterium marinum is a free-living, nontuberculous, photochromogenic mycobacterium, which can cause opportunistic infections in humans. It can cause infection through the skin that has undergone minor trauma, as the portal of entry from contaminated water, fish tanks and nonchlorinated swimming pools

Mycobacterium marinum is a slow growing mycobacterium (SGM) belonging to the genus Mycobacterium and the phylum Actinobacteria. The strain marinum was first identified by Aronson in 1926 and it is observed as a pathogenic mycobacterium. For example, tuberculosis like infections in fish (mycobacteriosis) and skin lesions in humans Pathogenesis. Mycobacterium tuberculosis can infect any area of body, including bones, joints, liver, spleen, gastrointestinal tract, and brain. In these sites its preferred residence is within cells of the reticuloendothelial system. Tuberculosis is not normally a rapidly developing disease, but is rather, if untreated, associated with years of declining health, culminating in death
