Presentation
We present the case of a 69-year-old man with significant respiratory comorbidities who presented with slow growing pulmonary nodules which cavitated. [ncbi.nlm.nih.gov]
Entire Body System
- Recurrent Otitis Media
A 10-year-old boy was referred to Tokyo Metropolitan Children's Medical Center with a 7-year history of recurrent otitis media despite treatment with antibiotics and ventilation tubes. [ncbi.nlm.nih.gov]
- Exposure to Contaminated Water
NTM inoculation through exposure to contaminated water or non-sterile instruments remains a challenge for dermatologists and risk to patients. We reported a case of cutaneous Mycobacterium massiliense infection following tattoo placement. [ncbi.nlm.nih.gov]
Gastrointestinal
- Gagging
Amplicons were sequenced using Mbak14 (5′- GRG RTA CTC GAG TGG CGA AC-3′), producing reads of up to 750 bp. [frontiersin.org]
Workup
On workup, it was confirmed that M. chelonae was the causative organism. He was given 8 weeks of antibiotics; however, there was worsening of the hip abscess on interval imaging. [ncbi.nlm.nih.gov]
After 4 days of incubation on the automated instrument, the two aerobic blood cultures bottles were positive and the patient was admitted to the hospital for further workup and therapy. [labmedicineblog.com]
(See Workup). In areas with a high prevalence of tuberculosis (TB), most cases of MAC infection are misdiagnosed and treated as TB. [3] In general, MAC infection is treated with 2 or 3 antimicrobials for at least 12 months. [emedicine.medscape.com]
Serum
- Lymphopenia
It has a known predilection for infecting the skin and subcutaneous tissue in immunocompromised patients, especially those with lymphopenia as a result of acquired immune deficiency syndrome (AIDS), allogeneic bone marrow transplantation, and those on [labmedicineblog.com]
Treatment
There are no reports describing the therapeutic use of tigecycline for the treatment of chronic otitis media caused by M. abscessus. [ncbi.nlm.nih.gov]
Treatment regimens and duration The treatment regimens and median duration are listed in Table 2. Table 2 Treatment of patients with M. marinum infection in Denmark. [nature.com]
Prognosis
Prognosis depends on the form of the disease. In the upper lobe cavitary form, lung destruction is usually progressive and can lead to respiratory failure and death if successful treatment is not instituted. [radiopaedia.org]
Prognosis With debridement and antibiotic therapy guided by susceptibility data, the prognosis is very good for most infections. [emedicine.medscape.com]
Prognosis With appropriate treatment using surgical debridement and systemic antibiotics, the majority of patients with cutaneous atypical mycobacterium infectious have a relatively good prognosis with no sequelae.[15] Kheir et al reported a resolution [eyewiki.aao.org]

Mycobacterium tuberculosis ( Mtb ) is the etiological agent of most cases of TB. Mtb is difficult to treat, in part, due to the presence of a sturdy hydrophobic barrier that prevents penetration of drugs through the cell wall. [pubs.rsc.org]
Mycobacterium tuberculosis is the etiological agent of tuberculosis (TB), the leading cause of death due to a single infectious agent, claiming 1.7 million lives in 2016. [cell.com]
Mycobacterium tuberculosis Mycobacterium tuberculosis is the etiologic agent of tuberculosis in humans. Humans are the only reservoir for the bacterium. Mycobacterium bovis is the etiologic agent of TB in cows and rarely in humans. [textbookofbacteriology.net]
Place specimen in a large infectious container (T146) and label as an etiologic agent/infectious substance. Necessary Information Specimen source and suspected organism identification are required. [microbiology.testcatalog.org]
Epidemiology
Since M. malmoense infection has rarely been reported in France, we also provide elements of the epidemiological investigation and a literature review of potential acquisition and transmission pathways of M. malmoense. [ncbi.nlm.nih.gov]
Moreover, an increasing number of experimental and epidemiological studies are showing that this genetic diversity also translates into important phenotypic variation. [books.google.it]
The method is highly reproducible and has been developed into a high-throughput assay for large molecular epidemiology projects. [mbovis.org]
Pathophysiology
Animal models have been pivotal in understanding tuberculosis (TB) pathophysiology. [erj.ersjournals.com]
Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test There are over 170 recognized species of mycobacteria and more than 100 Nocardia species. [mayocliniclabs.com]
Pathophysiology M. tuberculosis is transmitted airborne, i.e. by droplet infection. M. tuberculosis is a facultative intracellular parasite. When inhaled, the organism is taken up by alveolar macrophages. [radiopaedia.org]
A clear causation has not been established, however, and the pathophysiology remains largely unexplored. [7] MAI also causes cutaneous disease. [emedicine.medscape.com]
[…] predominance in the literature; however, some studies have found that women and patients greater than 50 years of age appear to be affected more, although this represents the most common demographic population for blepharoplasty and ptosis repair.[2][3] Pathophysiology [eyewiki.aao.org]

In E. coli and G. stearothermophilus, the α-helices adopt an “up” state where the α-helices enter the α 3 β 3 -domain and prevent the rotor from turning. [pnas.org]
Its cell wall prevents the fusion of the phagosome with a lysosome. Specifically, M. tuberculosis blocks the bridging molecule, early endosomal autoantigen 1 (EEA1); however, this blockade does not prevent fusion of vesicles filled with nutrients. [microbiologyinpictures.com]
You can prevent MAC by starting antiretroviral therapy (ART) early and not allow your CD4 count to get low. [webmd.com]
