Abstract

We report a case of disseminated Mycobacterium triviale infection in a 61-year-old male with no significant comorbidities. Definitive pathogen identification was provided by nucleotide matrix-assisted laser desorption ionization time-of-flight mass spectrometry(MALDI-TOF-MS) analysis. The results of a literature review underscore the critical role of MALDI-TOF MS in increasing the accuracy in detecting the pathogen. A regimen combining rifampin, fluoroquinolone, macrolide, and ethambutol appears to be a viable treatment option.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
