Mycobacterium abscessus infections in cystic fibrosis patients spreading: UK researchers - Outbreak News Today

The study, led by the University of Cambridge and the Wellcome Trust Sanger Institute, also suggests that conventional cleaning will not be sufficient to eliminate the pathogen, which can be transmitted through contaminated surfaces or in the air.. Mycobacterium abscessus, a species of multidrug resistant mycobacteria, has recently emerged as a significant global threat to individuals with cystic fibrosis and other lung diseases. It can cause a severe pneumonia leading to accelerated inflammatory damage to the lungs, and may prevent safe lung transplantation. It is also extremely difficult to treat - fewer than one in three cases is treated successfully.. It was previously thought that patients acquired the infection from the environment and that transmission between patients never occurred. The research team had previously studied one specialist CF centre in the UK and identified genetic and epidemiological evidence suggesting person-to-person transmission of M. abscessus but it was unclear ...

Revisiting human IL-12Rβ1 deficiency: a survey of 141 patients from 30 countries - Zurich Open Repository and Archive

Interleukin-12 receptor β1 (IL-12Rβ1) deficiency is the most common form of Mendelian susceptibility to mycobacterial disease (MSMD). We undertook an international survey of 141 patients from 102 kindreds in 30 countries. Among 102 probands, the first infection occurred at a mean age of 2.4 years. In 78 patients, this infection was caused by Bacille Calmette-Guérin (BCG; n = 65), environmental mycobacteria (EM; also known as atypical or nontuberculous mycobacteria) (n = 9) or Mycobacterium tuberculosis (n = 4). Twenty-two of the remaining 24 probands initially presented with nontyphoidal, extraintestinal salmonellosis. Twenty of the 29 genetically affected sibs displayed clinical signs (69%); however 8 remained asymptomatic (27%). Nine nongenotyped sibs with symptoms died. Recurrent BCG infection was diagnosed in 15 cases, recurrent EM in 3 cases, recurrent salmonellosis in 22 patients. Ninety of the 132 symptomatic patients had infections with a single microorganism. Multiple infections were ...

Phage Therapy Win: Mycobacterium Infection Halted

The first phage that they identified, named "Muddy", killed the strain of Mycobacterium abscessus isolated from the patient very efficiently, with no modifications necessary. However, the second and third phages (named ZoeJ and BPs) were genetically engineered using technology that the Hatfull lab has developed over the last decade. The researchers were able to delete the key protein that switches the phages from their lytic (killing) state to their lysogenic (dormant stage marked by the integration of the phage genome into the bacterial chromosome) state. This genetic deletion locked the phages into their lytic mode and created more efficient bacterial killers. For the phage BPs, the researchers went a step further and screened the phages to isolate a mutant that was able to infect the particular isolate from the patient.. Their method of engineering, adds Hatfull, allowed them to precisely delete the genes without leaving scars or additional material. This was important because the phages are ...

Clinical manifestations, diagnosis, and treatment of Mycobacterium haemophilum infections

Mycobacterium haemophilum is a slowly growing acid-fast bacillus (AFB) belonging to the group of nontuberculous mycobacteria (NTM) frequently found in environmental habitats, which can colonize and occasionally infect humans and animals. Several findings suggest that water reservoirs are a likely source of M. haemophilum infections. M. haemophilum causes mainly ulcerating skin infections and arthritis in persons who are severely immunocompromised. Disseminated and pulmonary infections occasionally occur. The second at-risk group is otherwise healthy children, who typically develop cervical and perihilar lymphadenitis. A full diagnostic regimen for the optimal detection of M. haemophilum includes acid-fast staining, culturing at two temperatures with iron-supplemented media, and molecular detection. The most preferable molecular assay is a real-time PCR targeting an M. haemophilum-specific internal transcribed spacer (ITS), but another approach is the application of a generic PCR for a ...

Nontuberculous Mycobacterial Infections | Harrison's Principles of Internal Medicine, 19e | AccessMedicine | McGraw-Hill Medical

In the United States, the incidence and prevalence of pulmonary infection with NTM, mostly in association with bronchiectasis (Chap. 312), have for many years been several-fold higher than the corresponding figures for tuberculosis, and rates of the former are increasing among the elderly. Among patients with cystic fibrosis, who often have bronchiectasis, rates of clinical infection with NTM range from 3% to 15%, with even higher rates among older patients. Although NTM may be recovered from the sputa of many individuals, it is critical to differentiate active disease from commensal harboring of the organisms. A scheme to help with the proper diagnosis of pulmonary infection caused by NTM has been developed by the American Thoracic Society and is widely used. The bulk of nontuberculous mycobacterial disease in North America is due to M. kansasii, organisms of the M. avium complex (MAC), and M. abscessus. ...

Mycobacterium celatum has been shown to cause disease in immunocompromised patients. We report a case of serious pulmonary infection caused by M. celatum in an apparently immunocompetent patient and review the characteristics of two other reported cases. Clinical and radiologic symptoms and signs included cough, malaise, and weight loss associated with cavitary lesions and pulmonary infiltrates. Although M. celatum is easy to detect in clinical specimens by liquid and solid media, it may be misidentified as a member of the M. tuberculosis complex or as M. xenopi. M. celatum pulmonary infection appears to respond to antimycobacterial chemotherapy, particularly with clarithromycin.

JCI - Volume 115, Issue 9

Genetic defects in the IFN-γ response pathway cause unique susceptibility to intracellular pathogens, particularly mycobacteria, but are rare and do not explain mycobacterial disease in the majority of affected patients. We postulated that acquired defects in macrophage activation by IFN-γ may cause a similar immunological phenotype and thus explain the occurrence of disseminated intracellular infections in some patients without identifiable immune deficiency. Macrophage activation in response to IFN-γ and IFN-γ production were studied in whole blood and PBMCs of 3 patients with severe, unexplained nontuberculous mycobacterial infection. In all 3 patients, IFN-γ was undetectable following mitogen stimulation of whole blood, but significant quantities were detectable in the supernatants of PBMCs when stimulated in the absence of the patients own plasma. The patients plasma inhibited the ability of IFN-γ to increase production of TNF-α by both autologous and normal donor PBMCs, and ...

Non-tuberculous mycobacteria (NTM) such as Mycobacterium avium intracellulare are commonly encountered by HIV physicians and management strategies are well established. Experience of other NTM is, however, limited. As HIV epidemiology in the United Kingdom changes, we may expect the emergence of these lesser known mycobacterial infections. We present the first UK report of an AIDS patient who has survived infection with disseminated Mycobacterium simiae despite cerebrospinal fluid involvement, an extremely high level of baseline HIV viraemia and treatment complicated by severe immune reconstitution inflammatory syndrome. ...

Serum Inflammatory Marker in Patients With Diagnosis of Nontuberculous Mycobacterial Pulmonary Infection - Full Text View -...

Nontuberculous mycobacteria (NTM), not like Mycobacterium tuberculosis, is ubiquitous in environment including soil and water. Therefore, NTM pulmonary infection is not diagnosed only by microbiology of respiratory specimen but also clinical and radiographical findings.(1) Due to airway NTM colonization is not uncommon in sputum, diagnosis of pulmonary NTM infection is a big challenge in clinical practice. Especially NTM burden is increasing in recent literature.(2,3) Besides, the short-term mortality is reported higher in patients with NTM infection in medical ICU by Shu et al.(4) Early diagnosis and then treatment of NTM infection become important though NTM infection is considered as indolent process before.(1) Inflammatory marker in the patients with NTM being isolated from respiratory specimens is an indicator for differentiating true infection from colonization.(5,6) Those inflammatory factors might include blood white count, C-reactive protein, cytokines, procalcitonin , trigger receptor ...

Clinical relevance of Mycobacterium chelonae-abscessus group isolation in 95 patients.

OBJECTIVES: To determine the clinical relevance of Mycobacterium chelonae-abscessus group isolation from clinical samples. METHODS: We retrospectively reviewed medical files of all patients from whom these mycobacteria were isolated between January 1999 and January 2005 and re-identified the isolates by rpoB sequencing. We applied the American Thoracic Society (ATS) diagnostic criteria to establish clinical relevance. RESULTS: Ninety-five patients were traced (56 M. chelonae, 25 Mycobacterium abscessus, 8 Mycobacterium massiliense, 6 Mycobacterium bolletii). Most isolates were cultured from pulmonary samples in patients with pre-existing pulmonary disease. Among patients with pulmonary isolates, 27% (20/74) meets ATS criteria; M. abscessus is most relevant (50%; 9/18), followed by M. massiliense (29%; 2/7), M. bolletii (20%; 1/5) and M. chelonae (18%; 8/44). Extrapulmonary disease presented as disseminated skin disease, eye disease specific for M. chelonae and otomastoiditis for M. abscessus. ...

Antibiotic treatment for nontuberculous mycobacteria in people with cystic fibrosis | Cochrane

Nontuberculous mycobacteria are bacteria that are in the same family as tuberculosis and are commonly found in the soil and water. These bacteria can be found in the lungs of people with cystic fibrosis and can cause their lung function to worsen. Although there are guidelines on which antibiotics to use to treat lung infection due to these bacteria, these recommendations are not specific for people with cystic fibrosis. It is also not clear which are the most effective antibiotics. The main purpose of this review was to determine whether treatment with different antibiotic combinations for nontuberculous mycobacterial infection would improve lung function or decrease the frequency of chest infections in people with cystic fibrosis. We found one randomized controlled trial but it included both people with and without cystic fibrosis and we could not get the information specifically about individuals with cystic fibrosis so could not include the information in this review. Until the time when ...

Clinical relevance of non-tuberculous mycobacteria isolated from respiratory specimens: seven year experience in a UK hospital ...

The frequency of isolation of non-tuberculous mycobacteria (NTM) species from respiratory specimens is increasing, however the clinical relevance of such identifications vary by mycobacterial species and geographical location. A retrospective study of 853 NTM isolates from respiratory samples from 386 patients over seven years was performed. Clinical records and radiographic information were examined. Clinical significance was assessed by American Thoracic Society diagnostic criteria. 25% of all patients with respiratory isolates met criteria for non-tuberculous mycobacterial pulmonary disease (NTM-PD). Significant symptoms were weight loss, fever, night sweats, productive cough and haemoptysis. HIV co-infection was a significant risk factor for disease. Cavities, nodules and tree-in-bud were significant radiographic findings. Mycobacterium avium complex (MAC) were the dominant species isolated from this patient cohort. Mycobacterium abscessus (M. abscessus) was the species most likely to cause ...

Mycobacterium abscessus - Wikipedia

Mycobacterium abscessus complex (MABSC) is a group of rapidly growing, multidrug-resistant non-tuberculous mycobacteria (NTM) species that are common soil and water contaminants. Although M. abscessus complex most commonly cause chronic lung infection and skin and soft tissue infection (SSTI), the complex can also cause infection in almost all human organs, mostly in patients with suppressed immune systems. Amongst NTM species responsible for disease, infection caused by M. abscesses complex are more difficult to treat due to antimicrobial drug resistance. M. abscessus cells are gram-positive, nonmotile, acid-fast rods of about 1.0 - 2.5 µm long by 0.5 µm wide. They may form colonies on Löwenstein-Jensen media that appear smooth or rough, white or greyish and nonphotochromogenic. M. abscessus shows growth at 28 °C and 37 °C after 7 days but not at 43 °C. It may grow on MacConkey agar at 28 °C and even 37 °C. It shows tolerance to saline media (5% NaCl) as well as 500 mg/l hydroxylamine ...

Mycobacterium mucogenicum bacteremia: major role of clinical microbiologists | BMC Infectious Diseases | Full Text

Mycobacterium mucogenicum is a rare but emerging cause of infections, especially in immunocompromised patients. We describe a new case of M. mucogenicum catheter-related bloodstream infection in a 34-year-old woman with ovarian cancer. M. mucogenicum was at first considered as a contaminant, and susceptibility testing was not performed. Usual susceptibility of M. mucogenicum motivated prescription of clarithromycin and moxifloxacin. Finally, our isolate was confirmed susceptible to both drugs. Clinical outcome was favorable with no relapse of infection after antibiotics discontinuation despite concomitant chemotherapy. Our case illustrates the need for a clinician-microbiologist dialogue in case of suspected M. mucogenicum infection to avoid delaying appropriate management.

A case of massive pericardial effusion caused by Mycobacterium simiae | Microbiology Society

Introduction: Mycobacterium simiae can cause disseminated infection in human immunodeficiency virus (HIV)‐infected patients, mainly with involvement of pulmonary and reticulo‐endothelial systems. Although this organism is also known to cause infections in non‐HIV‐infected individuals, to our knowledge there has been no report of pericardial effusion caused by M. simiae. Case presentation: We describe a case report with massive pericardial effusion caused by M. simiae in a non‐HIV‐infected female patient, who presented with complaints of gradually increasing breathlessness and cough over a period of 1 month. Acid‐fast bacilli were isolated from the pericardial effusion and subsequently confirmed as M. simiae by PCR‐RFLP. Conclusion: In an area where Mycobacterium tuberculosis infection is endemic, clinicians and microbiologists must be aware of the possibility of a non‐tubercular mycobacterial infection that could be misdiagnosed as a tubercular infection.

Random amplified polymorphic DNA genotyping of Mycobacterium malmoense. | Journal of Clinical Microbiology

The suitability of random amplified polymorphic DNA-PCR for the detection of differences between Mycobacterium malmoense strains was evaluated. With two of the 32 tested primers seven fingerprint patterns which proved excellent in distinguishing intraspecies variations of M. malmoense were obtained. The combination of the results obtained with the two primers permitted a clear separation of the strains. This technique is useful for analyzing species whose DNA sequences are not known. It can easily be adapted to test any mycobacterial species. ...

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 ...

Mycobacterium abscessus multispacer sequence typing | BMC Microbiology | Full Text

Analysis of the reference M. abscessus ATCC 19977 complete genome sequence yielded 3538 intergenic spacers with , 300 spacers were 200-700 bp in length. Successful PCR sequencing was achieved for 8 spacers in all the isolates studied; the sequences were deposited in the GenBank database (GenBank accession: KC352850 - KC352890). In M. abscessus isolates, including the 37 sequenced genomes, the spacer sequence variability was generated by one to 12 single nucleotide polymorphisms (SNPs) (spacers n°1 and n°8), one to 18 SNPs and one to two nucleotide deletions (spacer n°2), one to two SNPs (spacers n°3 and n°7) and nucleotide insertion (spacers n°2 and n°5). In "M. bolletii" isolates, the spacer sequence polymorphisms were generated by one SNP for spacer n°1, two SNPs and one deletion for spacer n°2, two SNPs for spacer n°3 and nine SNPs for spacer n°7. In "M. massiliense" isolates, including 28 sequenced genomes, the spacer sequence polymorphism were generated by nine SNPs and one ...

Cystic Fibrosis Unite | Cystic fibrosis CFBE41o‐ cells contain TLR1 SNP I602S and fail to respond to Mycobacterium abscessus

What did you find?. Receptors on cell surfaces are analogous to antennae, sensing what is in the local environment. Toll-like receptors (TLRs) are linked at the cell surface and recognize NTM. We found that CFBE41o‐ cells do not respond to M. abscessus due to a variation in the gene. This variation is called I602S and renders TLR1 nonfunctional. It is very common in Caucasians of northern European ancestry, the same population in which the CF ΔF508 is common, and it influences susceptibility to infection with other mycobacteria. ...

A novel molecular typing method of Mycobacteria based on DNA barcoding visualization | Journal of Clinical Bioinformatics |...

Nontuberculosis mycobacteria (NTM) are a diverse group of organisms that are ubiquitous in both natural and manmade environments [1]. Though less notorious than Mycobacterium tuberculosis (MTB), NTM infections are also of clinical significance and have been associated with worldwide outbreaks in the past. A previous study showed that the clinical symptoms and iconography representation of NTM were similar to MTB making it difficult to differentiate between the two diseases. Furthermore, treatment is also more difficult because most of NTM are naturally resistant to anti-tuberculosis drugs [2]. Thus, there is an urgent clinical need for tools that would enable accurate differentiation of MTB from NTM-induced disease. Since the genomes of different mycobacteria have been sequenced, it is now possible for us to generate a novel DNA barcoding technology for genotyping of mycobacteria.. Clinically, mycobacteria were traditionally characterized based on acid-fastness, smear and culture morphology, ...

Background: Nontuberculous mycobacteria (NTM) are a group of opportunistic pathogens and these are widely dispersed in water and soil resources. Identification of mycobacteria isolates by conventional methods including biochemical tests, growth rates, colony pigmentation, and presence of acid-fast bacilli is widely used, but these methods are time-consuming, labor-intensive, and may sometimes remain inconclusive. Materials and Methods: The DNA was extracted from NTM cultures using CTAB, Chelex, Chelex + Nonidet P-40, FTA® Elute card, and boiling The quantity and quality of the DNA extracted via these methods were determined using UV-photometer at 260 and 280 nm, and polymerase chain reaction (PCR) amplification of the heat-shock protein 65 gene with serially diluted DNA samples ...

Beach Body Coaches Shakeology |Should I Buy or Sell this Weight Loss Smoothie?

BeachBody Coaches - Are they being scammed? The Beach Body Coach Scam Story. So Ive been talking to my neighbor about her Beach Body workouts and her opportunity as a beach body coach.. By the way, Beachbody is one of the best mlm companies out there helping mompreneurs use mlm lead generation with their mlm programs to help individual take advantage of a multilevel marketing platform to earn extra money from home.. My neighbor tells me that she gets a lot of mlm leads and doesnt have to do a lot of mlm prospecting because the people in her upline just toss her leads from the mlm company list.. She told me just yesterday that she is making extra money and found a way to get money from home by paying for qualified mlm leads through some source she wouldnt mention. Using a mlm lead generation for a mlm marketing system like BeachBody is probably a smart enough idea to try.. After all, if you dont get the best mlm leads and you get a mlm lead that just totally sucks, this mlm lead generation ...

ASMscience | Paradoxical Reactions an

The immune response to mycobacterial infection is complex, involving several arms of the immune system. Organs are damaged by mycobacteria directly and also by the necrotic granulomatous immune response of the host to this pathogen. Ideally, mycobacterial infection is met with a balanced immune response that is sufficient to kill organisms but not so severe as to cause excessive tissue injury. Immunosuppression may promote growth of mycobacteria while decreasing tissue injury by the host response to the infection. Conversely, enhancement of the hosts immune response may kill more organisms but may also result in more organ damage.

Results All 15 patients were women with a mean age of 51 years [20-75]. The mean duration of treatment was 34.7 and 33.7 (4-69) months with etanercept and adalimumab, respectively. 8.3 infections for 100 patient years occurred. No mycobacteria infection, no lymphoproliferation and no cancer were observed. Also, no cutaneous, renal or other systemic flare of SLE occurred. No death was observed. After 2 years of follow-up, the mean decrease of DAS 28 and SLEDAI was -3 [-0.75 to -4.89] -5.13 [0 - 6], respectively. Corticosteroid dosage significantly decreased from 10mg/d to 5mg/d. No statistical significant increase in gene expressions of 4 different IFN-inducible genes, BAFF (2.2 to 0 fold), MX1 (17.2 to 0 fold), IFITM (1.2 to 0 fold), and PKR (19.3 to 0 fold) Likewise, no significant change was observed in serum levels of 3 IFN-inducibles chemokines: CXCL10 (82 to 56.2 pg/ml, p=0.87), CCL2 (343.8 to 729.4 pg/ml, p=0.375) and CCL19 (316.3 to 335.9 pg/ml, p=0.875).. ...

Forskningsprosjekter

Pathogenic bacteria contribute to globally important diseases such as mycobacterial diseases like tuberculosis and sepsis. We need to have an in-depth understanding of the immune responses and the killing mechanisms employed by host cells in counteracting infections, and what genetic factors may contribute in the susceptibility to infections. Emerging and rising trends in antibiotic resistance has urged the need for novel drug targets to bacterial infections. Identification of drug targets can be approached both from exploring molecular and genetic mechanisms of host defense to infection, and characterizing evasion mechanisms employed by the bacterium to avoid killing within the host. We hypothesise that Keap1 plays a central role in mycobacterial infections and bacterial sepsis, and propose to characterize in detail how Keap1 and related molecules may regulate the 3 pathways of phagocytosis, inflammatory signaling and autophagy. Based on our preliminary results that Keap1 regulates inflammation ...
