Efficient inactivation of clinical samples containing mycobacteria is crucial for biosafety during shipment and handling. When stored in RNAlater, Mycobacterium tuberculosis H37Ra remains viable, and our results suggest that at -20 °C and 4 °C changes in the mycobacterial transcriptome are possible. Only GTC-TCEP and DNA/RNA Shield inactivate sufficiently for shipment.

Article Synopsis
  • RbpA is a critical protein for Mycobacterium tuberculosis growth, impacting transcription and antibiotic response, but its regulatory mechanisms are not fully understood.
  • Significant structural changes in RNA polymerase occur when it interacts with RbpA, revealing important amino acids for transcription regulation and dynamic behavior of the complex.
  • The study identifies potential ligands for RbpA's interaction site, laying the groundwork for future research on developing inhibitors that target RbpA's regulatory role in transcription.

The enduring pathogenicity of can be attributed to its lipid-rich cell wall, with mycolic acids (MAs) being a significant constituent. Different MAs' fluidity and structural adaptability within the bacterial cell envelope significantly influence their physicochemical properties, operational capabilities, and pathogenic potential. Therefore, an accurate conformational representation of various MAs in aqueous media can provide insights into their potential role within the intricate structure of the bacterial cell wall.

Unlabelled: is well adapted to survive and persist in the infected host, escaping the host's immune response. Since polyamines such as spermine, which are synthesized by infected macrophages, are able to inhibit the growth of , the pathogen needs strategies to cope with these toxic metabolites. The actinomycete , a close relative of makes use of a gamma-glutamylation pathway to functionally neutralize spermine.

Latent tuberculosis infection (LTBI) is a critical stage of tuberculosis infection in which Mycobacterium tuberculosis (MTB) is dormant and does not cause active disease. Traditionally, the most commonly used clinical methods for diagnosing LTBI have been the tuberculin skin test (TST) and the interferon-gamma release assay (IGRA). Recently, however, novel skin tests, molecular biology techniques, and cytokine biomarkers have been developed.

Early diagnosis and appropriate treatment are essential for reducing morbidity and mortality in tuberculous meningitis (TBM). This study aimed to evaluate the diagnostic performance of the Xpert MTB/RIF assay for the diagnosis of TBM in patients with subacute lymphocytic meningitis. This cross-sectional study included 65 cerebrospinal fluid (CSF) specimens from patients at Maharaj Nakorn Chiang Mai University Hospital, Thailand, between January 2015 and March 2016.
