Cold abscesses in the cervical region, without associated general and functional signs, may be tuberculous lymph nodes or infected foci due to atypical mycobacteria. In the former, long-term antibiotic therapy, possibly followed by surgery conducted under conditions applicable to curettage for these lesions, is formally indicated. Treatment is of only moderate value in the second case, and spontaneous healing without other than esthetic sequelae usually occurs. These two lesions are quite different, therefore, but this was not recognized, and confusion still exists in many cases, for two reasons. Firstly, acid-alcohol-resistant bacilli are found in the pus in both cases, and a distinction cannot be made between them without culture. Secondly, pathological examination of specimens removed demonstrates identical appearances. The only way to distinguish between the two lesions, and to avoid excessively long or aggressive treatment, is by means of bacterial culture.

The diagnosis and management of complex neurological conditions such as New-Onset Refractory Status Epilepticus (NORSE) and central nervous system (CNS) infections caused by non-tuberculous mycobacteria (NTM) pose substantial difficulties in intensive care units (ICUs). This article combines a case report and a literature review that explores the diagnostic dilemmas and therapeutic strategies for these critical conditions. We report the case of an 83-year-old female with chronic granulomatous meningitis secondary to NTM, presenting a challenging diagnostic and complex management complexity typical of such a rare disease through a period time of five years.

The health burden of waterborne nontuberculous mycobacteria (NTM) is a rising concern. While the water supply systems can serve as a potential reservoir for NTM, their abundance, diversity, and transmission pathways remain unknown. This study aimed to characterize the prevalence and regrowth of NTM in building water supply system in a hospital where many M.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Background: Accurate and timely diagnosis of mycobacterial infections, including complex (MTBC) and nontuberculous mycobacteria (NTM), is crucial for effective disease management.
Methods: This study evaluated the performance of the NeoPlex TB/NTM-5 Detection Kit (NeoPlex assay, Seongnam, Republic of Korea), a multiplex real-time PCR assay that incorporates melting curve analysis, compared with the line-probe assay (LPA). The NeoPlex assay could simultaneously detect and differentiate MTBC from five other NTM species: , , , , and .
