Evaluation of a Commercial Multiplex Real-Time PCR with Melting Curve Analysis for the Detection of Complex and Five Nontuberculous Mycobacterial Species.
Microorganisms
December 2024
Department of Laboratory Medicine, Korea University Anam Hospital, Korea University College of Medicine, Seoul 02841, Republic of Korea.
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 .
Development and evaluation of multiplex real-time PCR for rapid identifying major pathogenic mycobacteria from pulmonary and extrapulmonary clinical samples in eastern China.

Clinical Laboratory Center, Hangzhou Red Cross Hospital, Hangzhou, Zhejiang, 310003, China.
Background: Diseases caused by (MTB) and non-tuberculous mycobacteria (NTM) have similar clinical symptoms but require different treatments. Rapid and accurate identification of MTB and NTM is essential for proper patient management and treatment.
Methods: To develop and assess a multiplex real-time fluorescence PCR (Multiplex PCR) method for rapid identification of MTB, complex (MAC), M.

Mycobacterial hemerythrin-like proteins (HLPs) are important for the survival of pathogens in macrophages. Their molecular mechanisms of function remain poorly defined but recent studies point to their possible role in nitric oxide (NO) scavenging. Unlike any nonheme diiron protein studied so far, the diferric HLP from (-HLP) reacts with NO in a multistep fashion to consume four NO molecules per diiron center.

SAMRC Centre for Tuberculosis Research, Division of Molecular Biology and Human Genetics, Faculty of Medicine and Human Genetics, Stellenbosch University, Cape Town, South Africa.
Objectives: Nontuberculous mycobacteria (NTM) are increasingly recognized opportunistic pathogens found ubiquitously in the environment. The presence of multiple NTM species at the site of disease complicates diagnosis and treatment.
Case And Management: A 40-year-old patient who tested positive for HIV, with an absolute clusters of differentiation 4+ T-cell count of 3 cells/µl and cryptococcaemia, presented with hemoptysis, productive cough, and weight loss.
Diagnosing Mycobacterium Kansasii in Shoulder Periprosthetic Joint Infection: A Rare Case Report.
J Orthop Case Rep
January 2025
Department of Orthopedics, University of Illinois College of Medicine, University of Illinois at Chicago, Chicago, Illinois, USA.
Introduction: Periprosthetic joint infections (PJIs) of the shoulder complicate approximately 0.7% of primary and 15.4% of revision shoulder arthroplasties.
