Mycobacterium


Presentation

  • We present here the first two cases in Canada. Both patients presented with nonspecific extracardiac symptoms 1 year after undergoing minimally invasive mitral surgical repair.[ncbi.nlm.nih.gov]
  • We present a case of cutaneous infection caused by M. immunogenum in a Spanish woman.[ncbi.nlm.nih.gov]
  • Abstract A 66-year-old man with a history of renal transplant on chronic immunosuppression presented to his primary care physician with a swollen right index finger. On examination, mild swelling was present.[ncbi.nlm.nih.gov]
  • We present detailed clinical, microbiological and radiological elements strongly arguing for M. malmoense true pathogenicity.[ncbi.nlm.nih.gov]
  • 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]
Impaired Balance
  • The hearing loss and impaired balance developed over a 3-day period prior to the onset of facial palsy. Further investigation with a CT scan and MRI scan led to a diagnosis of vestibular schwannoma.[ncbi.nlm.nih.gov]
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]
Heart Failure
  • The use of left ventricular assist device is associated with improvement in survival in patients with refractory heart failure. However, driveline infection limits the success of its use as it is associated with significant mortality.[ncbi.nlm.nih.gov]

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]
Clostridium Perfringens
  • For purposes of approximation, use of cell volumes estimated for other bacteria such as E. coli ( 18 ), Bacillus subtilis ( 43 ), and Clostridium perfringens ( 19 ) would suggest that Mtb's intracellular glutamate concentration may be on the order of[doi.org]
Human Papillomavirus
  • KEYWORDS: Giant condyloma acuminatum; Mycobacterium indicus pranii; human papillomavirus; immunotherapy[ncbi.nlm.nih.gov]

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]
  • Antituberculous treatment was continued, and additional treatment with oral prednisolone 20 mg daily for 1 month tapering over 10 weeks was introduced, resulting in a decrease in lymphadenopathy.[ncbi.nlm.nih.gov]
  • Furthermore, the prevalence of multidrug resistance among the Lebanese M. simiae isolates is very high limiting the treatment options.[ncbi.nlm.nih.gov]
  • After short antibiotic treatment, nivolumab was administered. Two months after nivolumab treatment, the nodule improved along with a good tumour response.[ncbi.nlm.nih.gov]
  • M. abscessus knee infections are rare, and there are no specific guidelines to inform treatment or successful treatment regimens for periprosthetic knee infections.[ncbi.nlm.nih.gov]

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]
  • Finally, since we did not analyse an association of co-infection with the outcome or prognosis, we could not show the clinical significance of co-infection in this study.[bmjopenrespres.bmj.com]

Etiology

  • […] diseases; Infections; Medical management; Valvar diseases Publication type, MeSH terms, Substances Publication type Case Reports MeSH terms Anti-Bacterial Agents/administration & dosage Anti-Bacterial Agents/therapeutic use Diagnosis, Differential Dyspnea/etiology[ncbi.nlm.nih.gov]
  • 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 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]
  • […] classified as a localized cellulitis , as a subcutaneous abscess, or as disseminated disease. [12] According to some series, as many as 75% of patients with disseminated disease are initially colonized with M chelonae , and skin trauma is thought to be the etiology[emedicine.medscape.com]

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]
  • A population-based molecular epidemiological study was conducted to determine TB transmission in Ghana.[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]
  • Pathophysiology M chelonae , like many NTM, are ubiquitous in the environment and have been isolated from both natural and potable freshwater sources, soil, contaminated solutions, and reptiles. [7] The organism can grow in distilled and unsupplemented[emedicine.medscape.com]

Prevention

  • Increased awareness among the medical community and at-risk population should be maintained to facilitate more rapid diagnosis and prevent inappropriate treatment of this potentially devastating condition.[ncbi.nlm.nih.gov]
  • 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]
  • You can prevent MAC by starting antiretroviral therapy (ART) early and not allow your CD4 count to get low.[webmd.com]
