Abstract
Objective Drug-resistant tuberculosis is a major public health problem, especially in the southern region of Xinjiang, China; however, there is little information regarding drug resistance profiles and mechanism of Mycobacterium tuberculosis in this area. The aim of this study was to determine the prevalence and molecular characteristics of M. tuberculosis resistant to four anti-tuberculosis drugs from this area. Methods Three hundred and forty-six isolates from the southern region of Xinjiang, China were included and used to perform phenotypic drug susceptibility testing and whole genome sequencing (WGS). Mutations in seven loci associated with drug resistance, including rpoB for rifampicin (RMP), katG, inhA promoter and oxyR-ahpC for isoniazid (INH), rrs 530 and 912 loops and rpsL for streptomycin (STR), and embB for ethambutol (EMB), were characterized. Results Among 346 isolates, 106, 60, 70 and 29 were resistant to INH, RMP, STR and EMB, respectively; 132 were resistant to at least one of the four anti-tuberculosis drugs and 51 were multi-drug resistant (MDR). Beijing genotype and retreated patients showed a significantly increased risk for developing MDR tuberculosis. Compared with the phenotypic data, the sensitivity and specificity for WGS to predict resistance were 96.7% and 98.6% for RMP, 75.5% and 97.1% for INH, 68.6% and 99.6% for STR, 93.1% and 93.7% for EMB, respectively. The most common mutations conferring RMP, INH, STR and EMB resistance were Ser450Leu (51.7%) in rpoB, Ser315Thr (44.3%) in katG, Lys43Arg (35.7%) in rpsL and Met306Val (24.1%) in embB. Conclusion This study provides the first information on the prevalence and molecular characters of drug resistant M. tuberculosis in the southern region of Xinjiang, China, which will be helpful for choosing early detection methods for drug resistance (ig, molecular methods) and subsequently initiation of proper therapy of tuberculosis in this area.

A comparative study of phenotypic and genotypic first- and second-line drug resistance testing of Mycobacterium tuberculosis. Biologicals 2017; 49:33-38. [PMID: 28716625 DOI: 10.1016/j.biologicals.2017.07.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2017] [Revised: 07/04/2017] [Accepted: 07/08/2017] [Indexed: 11/29/2022] Open
Abstract
This study aimed to evaluate the frequency of resistance to first- and second-line drugs using phenotypic and genotypic methods and its correlation with resistance-linked mutations in Mycobacterium tuberculosis (M. tb) isolated in Iran. Three different methods, including the indirect proportion method(PM), direct and indirect nitrate reductase assay(NRA), and direct sequencing were used to assess drug resistance. In this study, sensitivity, specificity, agreement, costs, and turnaround time of these methods were compared in 395 smear positive isolates. Compared to the PM, the NRA and the direct sequencing methods demonstrated higher specificity, sensitivity, and agreement for detection of all anti-tuberculosis drugs. The NRA had a short turnaround time and was more cost-effective than the other methods. Mutations in codon 531 in rpoB, 315 in katG, 18 in rpsL, and 306 in embB were associated with high-level resistance to the first-line drugs, and mutations in codon 94 in gyrA, and A1401G in rrs were correlated with resistance to the second-line drugs. We found that the NRA is a highly sensitive, specific, inexpensive, and rapid test with strong potential to be a useful and interesting alternative tool, particularly in low-income countries. In addition, these molecular data will be helpful for developing new molecular methods for detecting first- and second-line drug-resistant M. tb.
