Mycobacterium Fortuitum disease: Malacards - Research Articles, Drugs, Genes, Clinical Trials

NIH Rare Diseases : 50 mycobacterium fortuitum is a bacteria that can cause infections of many areas of the body including the skin, lymph nodes, and joints. it belongs to a group of bacteria, known as nontuberculous mycobacterium, as it is different from the mycobacterium that causes tuberculosis. it can be found in natural and processed water, sewage, and dirt. healthy people usually do not get mycobacterium fortuitum infections; however, they may occur after surgery, in people with an impaired immune system, or after exposure to a contaminated medical device (such as an endoscope). it is uncommon for this condition to cause lung disease, but mycobacterium fortuitum infection can lead to skin disease, osteomyelitis (inflammation of the bone), joint infections, and eye disease. the signs and symptoms of infection differ depending on the infection site. treatment also depends on the site of the infection, but usually includes prolonged use of antibiotics. last updated: 2/22/2017 ...

Mycobacterium fortuitum - Wikipedia

Mycobacterium fortuitum is a nontuberculous species of the phylum actinobacteria (Gram-positive bacteria with high guanine and cytosine content, one of the dominant phyla of all bacteria), belonging to the genus mycobacterium. Mycobacterium fortuitum is a fast-growing species that can cause infections. The term "fast growing" is a reference to a growth rate of 3 or 4 days, when compared to other Mycobacteria that may take weeks to grow out on laboratory media. Pulmonary infections of M. fortuitum are uncommon, but Mycobacterium fortuitum can cause local skin disease, osteomyelitis (inflammation of the bone), joint infections and infections of the eye after trauma. Mycobacterium fortuitum has a worldwide distribution and can be found in natural and processed water, sewage, and dirt. Bacteria classified as Mycobacteria, include the causative agents for tuberculosis and leprosy. Mycobacteria are sometimes referred to as "acid-fast bacteria," a term referencing their response to a laboratory ...

Pseudo-outbreak of Mycobacterium fortuitum on a Human Immunodeficiency Virus Ward: Transient Respiratory Tract Colonization...

Infection Control surveillance revealed an abnormally high number of sputum samples growing Mycobacterium fortuitum from a single ward that houses the human immunodeficiency virus service. We investigated the outbreak using a retrospective case-control study and molecular epidemiology. A total of 47 patients were identified with ⩾1 sputum sample that grew M. fortuitum. No significant demographic or clinical variables were found to be associated with colonization. Environmental investigation demonstrated that the M. fortuitum isolated from patients was identical to the ice machine isolates by pulsed-field gel electrophoresis. Fortunately, there has been no evidence of progressive pulmonary disease developing in our patients after ⩾6 months of follow-up. All cases were thought to represent transient colonization and not infection. The ice machine was disconnected and cleaned successfully with vinegar and then bleach. Only when a 0.5-µm filter was installed were no further patients colonized ...

Virulent Mycobacterium fortuitum restricts NO production by a gamma interferon-activated J774 cell line and phagosome-lysosome...

The virulence of different isolates of Mycobacterium has been associated with two morphologically distinguishable colonial variants: opaque (SmOp) and transparent (SmTr). in this report we used an in vitro assay to compare macrophage (Mphi) responses to SmOp and SmTr Mycobacterium fortuitum variants, taking advantage of the fact that these variants were derived from the same isolate. Cells preactivated or not with gamma interferon (IFN-gamma) were infected with SmOp or SmTr M. fortuitum. We showed that SmOp and SmTr induced different levels of nitric oxide (NO) production by IFN-gamma-stimulated Mphi. Indeed, the amount of IFN-gamma-induced NO production by J774 cells was 4.8 to 9.0 times higher by SmOp (23.1 to 37.7 muM) compared to SmTr infection (3.9 to 4.8 muM) (P = 0.0332), indicating that virulent SmTr bacilli restricted NO production. in addition, IFN-gamma-induced NO production by Mphi was higher when correlated with reduction of only avirulent SmOp bacillus viability.

In Vitro Susceptibilities of Rapidly Growing Mycobacteria to Telithromycin (HMR 3647) and Seven Other Antimicrobials |...

Among the rapidly growing mycobacteria (RGM), the members of the Mycobacterium fortuitum complex are the species most often associated with human infections (11). Therapy of these infections is quite different from the treatment of tuberculosis and also from the treatment of disease caused by other, slowly growing mycobacteria (2). There are many differences in the susceptibility of the members of this group of mycobacteria in published studies, and several of them revealed that in vitro susceptibility correlates with clinical response to therapy (10). Here we report a study of the in vitro susceptibility of these species to some antimicrobials, including newly developed ones.. A total of 94 (Mycobacterium fortuitum [48 strains],Mycobacterium chelonae [25 strains], Mycobacterium mucogenicum [3 strains], Mycobacterium peregrinum[12 strains], and Mycobacterium abscessus [6 strains]) strains of RGM isolated from clinical samples were tested. Prior to testing, strains were subcultured, checked for ...

Multisite Reproducibility of Results Obtained by the Broth Microdilution Method for Susceptibility Testing ofMycobacterium...

Susceptibility testing of clinically significant isolates of the rapidly growing mycobacteria is recommended because these organisms differ in susceptibility to the antimicrobial agents commonly used for therapy (2, 4, 11-16). Based on data from the Centers for Disease Control and Prevention, many laboratories in the United States do such testing by a variety of methods (21). No standardized susceptibility test method currently exists for the rapidly growing mycobacteria, but investigators who have studiedM. abscessus, M. chelonae, and the M. fortuitum group extensively recommend broth microdilution testing (3, 11, 12). Data concerning other species of rapidly growing mycobacteria are very limited. Because of variability in the appearance of growth of M. abscessus, M. chelonae, and the M. fortuitum group in microdilution trays, unlike most bacterial isolates, interpretation of the MIC may be difficult. The primary focus of our study, therefore, was to evaluate the reproducibility of the broth ...

Mycobacterium fortuitum as a cause of peritoneal dialysis catheter port infection. A clinical case and a review of the...

Predisposing factors described are: immunesupression, peritonitis resistant to several cycles of antibiotic, surgery, accidental trauma, or injections.. Auramin or Ziehl-Neelsen staining techniques reveal the acid-alcohol resistance of mycobacteria. A culture should be made in 2 specific media: a solid egg-based medium (Lowenstein-Jensen) and a liquid medium allowing for automated reading (MGIT, MB/BacT, ESP). Colony growth usually occurs within 7 days and is identified by means of faster and more accurate phenotyping (biochemical tests) and genotyping systems, based on the detection of species-specific DNA sequences.. RGAMs are relatively resistant to standard disinfectants and are able to generate biofilms to survive. Consequently in many cases, peritoneal catheters must often be removed or replaced. In our literature review the dialysis catheter was replaced in 65.2% of patients. The catheter was also removed in all cases showing peritonitis or tunnel infection, patients with M. abcessus ...

Background: Weight loss clinics are common in the United States. Unfortunately, some offer dubious weight loss methods such as self-administered human chorionic gonadotropin (HCG) injections. HCG products are unregulated, yet, widely available. Infection is among the risks potentially associated with this treatment. We report a case of skin infection caused by Mycobacterium fortuitum after HCGinjection.. Case Presentation: A 51-year-old woman with a history of hypogammaglobulinemia presented with an eight week history of a tender abdominal lesion. The lesion was at the site of a previous HCG injection.Acid-fast bacilli (AFB) culture grew Mycobacterium fortuitum. Based on the organisms susceptibility profile, sulfamethoxazole-trimethoprim 800-160mg and ciprofloxacin 500 mg were both prescribed. The case was referred to the Missouri Department of Health. Based on clinical progress treatment was continued for a total of six months.. Conclusions: This case illustrates the potential for cutaneous ...

Activities of ciprofloxacin and ofloxacin against rapidly growing mycobacteria with demonstration of acquired resistance...

The susceptibility to ciprofloxacin of 548 clinical isolates of rapidly growing mycobacteria belonging to eight subgroups or species was determined. The 170 isolates of Mycobacterium fortuitum biovar.fortuitum were most susceptible; the MIC for 90% of the organisms was 0.125 micrograms/ml. The other biovariants of M. fortuitum, M. smegmatis, and the M. chelonae-like organisms were less susceptible; the modal MIC was 0.5 micrograms/ml, and the MIC for 90% of organisms was 1.0 micrograms/ml. The two subspecies of M. chelonae were generally resistant, with only 8% of 206 isolates falling in the moderately susceptible category (MIC, 2 micrograms/ml) and only 2% falling in the susceptible category (MIC, less than or equal to 1 micrograms/ml). MICs of ofloxacin averaged 1 to 2 dilutions higher than those of ciprofloxacin for all subgroups tested. Three patients with M. fortuitum cutaneous disease relapsed after an initial response to therapy with ciprofloxacin, and their isolate was shown to have ...

The activities of eight quinolones (ciprofloxacin, clinafloxacin, levofloxacin, ofloxacin, A-80556, sparfloxacin, temafloxacin and tosufloxacin) and three macrolides (azithromycin, clarithromycin and erythromycin) against 98 clinical isolates of Mycobacterium tuberculosis and 120 isolates of five different atypical mycobacterial species including 20 Mycobacterium kansasii, 25 Mycobacterium scrofulaceum, 25 Mycobacterium avium/intracellulare, 25 Mycobacterium chelonae and 25 Mycobacterium fortuitum were determined with the Middlebrook 7H9 broth macrodilution method. Sparfloxacin, clinafloxacin, levofloxacin, ciprofloxacin and ofloxacin were active against M. tuberculosis (MIC90 0.06-0.5 mg/L; MBC90 0.125-2.0 mg/L). However, higher MIC90S and MBC90S of these quinolones were obtained for strains of multi-drug resistant M. tuberculosis. The macrolides tested had poor activity against M. tuberculosis isolates (MIC90 , 8.0 mg/L). Furthermore, high MIC90S of the quinolones and macrolides (2.0 to 8.0 ...

The Non-Pathogenic Mycobacteria M. Smegmatis and M. Fortuitum Induce Rapid Host Cell Apoptosis Via a Caspase-3 and TNF...

The HIV pandemic raised the potential for facultative-pathogenic mycobacterial species like, Mycobacterium kansasii, to cause disseminating disease in humans with immune deficiencies. In contrast, non-pathogenic mycobacterial species, like M. smegmatis, are not known to cause disseminating disease even in immunocompromised individuals. We hypothesized that this difference in phenotype could be explained by the strong induction of an innate immune response by the non-pathogenic mycobacterial species.. A comparison of two rapid-growing, non-pathogenic species (M. smegmatis and M. fortuitum) with two facultative-pathogenic species (M. kansasii and M. bovis BCG) demonstrated that only the non-pathogenic bacteria induced strong apoptosis in human THP-1 cells and murine bone marrow-derived macrophages (BMDM) and dendritic cells (BMDD). The phospho-myo-inositol modification of lipoarabinomannan (PI-LAM) isolated from non-pathogenic species may be one of the cell wall components responsible for the ...

Mycobacterium avium Complex and Atypical Mycobacterial Infections in the Setting of HIV Infection

Because 40% of patients with advanced HIV disease are likely to develop disseminated MAC, it makes sense to develop a strategy for preventing this disease in patients at risk. Few specific risk factors, other than a low CD4 lymphocyte count, have been defined. Therefore, any current prophylactic strategy must be applied to the entire population at risk, specifically, those patients with ,50 CD4 cells/µL. Results of combined analysis of 2 randomized, placebo-controlled trials of rifabutin prophylaxis, which included more than 1,000 patients with advanced HIV disease, showed that 300 mg/day of rifabutin reduced the incidence of mycobacteremia by one half.(25) Of interest, patients who received rifabutin and subsequently developed mycobacteremia had blood MAC isolates that retained susceptibility to rifabutin. Neither trial alone, nor the combined analysis, however, demonstrated that rifabutin significantly reduced mortality. Combined analysis of both trials revealed an increased incidence of ...

Mycobacterium avium, Mycobacterium marinum, and Mycobacterium peregrinum can all grow inside Acanthamoeba and other environmental amoebae. Once ingested by Acanthamoeba, M. avium upregulates a number of genes, many of them similar to genes upregulated upon phagocytosis of M. avium by macrophages. Mycobacteria ingested by amoebae grow intracellularly, acquiring an invasive phenotype, evident when the bacterium escapes the infected amoeba. Once inside of amoeba, it has been shown that mycobacteria are protected from antibiotics and disinfectants, such as chlorine.

Searching for an immunogenetic factor that will illuminate susceptibility to non-tuberculous mycobacterial disease

The incidence of pulmonary non-tuberculous mycobacteria (NTM) disease in otherwise healthy adults is increasing as the population ages. The organisms are ubiquitous so susceptibility probably reflects a deficiency in a protective immune response. Here we investigate if singlenucleotide polymorphisms (SNP) affecting cytokines, chemokines and their receptors associate with pulmonary NTM disease. Samples from NTM patients (n=79) and healthy controls (n=188) were genotyped using TaqMan probes. Of the 16 SNPs assessed, IL28B-rs8099917*TG (rs8099917; P=0.01, OR=2.2), TNFA-1031*CC (rs1799964; p=0.02, OR=0.48) and IL10-1082*AA (rs1800896; P=0.001, OR=0.33) were significantly associated with NTM disease. IL28B-rs8099917 and IL10-1082 have been associated with perturbations of the Th1/Th2 balance, whilst TNFA-1031*CC associates with sensory neuropathy in HIV patients. IL10-1082 warrants further investigation because we observed high production of IL-10 in blood mononuclear cells from NTM patients. © 2013 ...
