Introduction: Tuberculosis is prevalent in high-burden countries. However, spinal multi-drug resistant tuberculosis (MDR-TB) in patients with normal immune function is a disease that is prone to misdiagnosis and even delayed diagnosis. Recently, we successfully treated one such patient.

This comparative study aimed at qualifying a broth microdilution (BMD) assay for phenotypic drug susceptibility testing (pDST) of complex (MTBC) strains for implementation in a routine DST workflow. The assay was developed based on the EUCAST (European Committee on Antimicrobial Susceptibility Testing) reference protocol for determination of the minimum inhibitory concentration (MIC) of 14 anti-tuberculous drugs (isoniazid [INH], rifampicin [RIF], ethambutol [EMB], amikacin [AMI], moxifloxacin [MFX], levofloxacin [LFX], bedaquiline [BDQ], clofazimine [CFZ], delamanid [DLM], pretomanid [PA], para-aminosalicylic acid [PAS], linezolid [LZD], ethionamide [ETH], and cycloserine [CS]). Forty MTBC strains with various drug resistance profiles were tested to determine the agreement between MIC results and genotypic drug susceptibility testing (gDST) results derived from whole-genome sequencing (WGS).

Background: Whole-genome sequencing (WGS)-based prediction of drug resistance in Mycobacterium tuberculosis has the potential to guide clinical decisions in the design of optimal treatment regimens.
Methods: We utilized WGS to investigate drug resistance mutations in a 32-year-old Tanzanian male admitted to Kibong'oto Infectious Diseases Hospital with a history of interrupted multidrug-resistant tuberculosis treatment for more than three years. Before admission, he received various all-oral bedaquiline-based multidrug-resistant tuberculosis treatment regimens with unfavourable outcomes.

Background: Children represent a particularly vulnerable demographic in the context of drug-resistant (DR) tuberculosis (TB) due to their increased likelihood of close contact with adults diagnosed with the disease. Approximately 25 000-30 000 children develop DR-TB annually. While treatment success rates for DR-TB in children surpass those in adults, children and adolescents encounter distinct challenges throughout the diagnosis and treatment of DR-TB (including MDR-TB, Pre-XDR TB, and XDR-TB).
