atypical mycobacterium granulomatous skin infections are often accured by mycobacterium marinum, m. ulcerans, m. fortuitum, and m. avium colonies. skin infections probably originate from an environmental source such as contacting with aquatic animals, fish farming and swimming in the pools, and inoculate into skin through skin wounds, scratches, trauma, and surgery. the lesions appear as purple...
BACKGROUND The pathogenesis of Mycobacterium tuberculosis largely depends on the secretion of the 6-kD early secreted antigenic target ESAT-6 (EsxA) and the 10-kD culture filtrate protein CFP-10 (EsxB) via the ESX-1/typeVII secretion system. Although gene products from the core RD1 region have been shown to be deeply implicated in this process, less is known about proteins encoded further upstr...
The hallmark of tuberculosis (TB) is the formation of granulomas, which are clusters of infected macrophages surrounded by additional macrophages, neutrophils and lymphocytes. Although it has long been thought that granulomas are beneficial for the host, there is evidence that mycobacteria also promote the formation of these structures. In this study, we aimed to identify new mycobacterial fact...
The immunomodulatory drug lenalidomide is currently being evaluated for its antineoplastic properties in treating hematologic malignancies. However, its potential role in augmenting immune reactions against opportunistic infections has not been explored. We report the rapid resolution of chronic Mycobacterium marinum infection in a patient following initiation of lenalidomide therapy for chroni...
The esat-6 and cfp-10 genes are essential for virulence in Mycobacterium tuberculosis. Among nontuberculous mycobacteria, we found these genes only in M. kansasii, M. szulgai, M. marinum, and M. riyadhense, with unique sequences. This adds a phylogenetic and taxonomical characteristic and may represent a virulence factor for nontuberculous mycobacteria.
Tumor necrosis factor-alpha inhibitors are important adjunctive therapies for rheumatologic diseases. These agents increase the risk for granulomatous disease. We present a case of a woman with severe rheumatoid arthritis on infliximab who developed multiple nodular skin lesions. Biopsies grew Mycobacterium marinum. New lesions developed through therapy, necessitating surgical debulking.
Mycobacterium marinum, a well-recognized cutaneous pathogen, is usually treated by chemotherapy without available standardized in vitro susceptibility testing information. In this study, we have attempted to apply the stable-gradient method (Etest; AB Biodisk, Solna, Sweden) to susceptibility testing of M. marinum in order to assess the activities of eight antimicrobial agents against 60 recent...
During a tuberculosis infection and inside lipid-laden foamy macrophages, fatty acids (FAs) and sterols are the major energy and carbon source for Mycobacterium tuberculosis. Mycobacteria can be found both inside a vacuole and the cytosol, but how this impacts their access to lipids is not well appreciated. Lipid droplets (LDs) store FAs in form of triacylglycerols (TAGs) and are energy reservo...
