Tuberculosis (TB), usually caused by Mycobacterium tuberculosis (MTB), remains a major threat to the public health worldwide.
Although the directly observed treatment, short-course (DOTS) strategy has significantly reduced the incidence of TB in recent years, the emergence of drug-resistant TB has severely hampered TB prevention and control, especially regarding multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB)1. TB epidemics are unevenly distributed in China, and there is a high prevalence in rural areas, especially those that are underdeveloped in the northwest and southwest of China1. Communicable Diseases Intelligence - OCT 2020 - Retrospective analysis of multidrug-resistant tuberculosis case notifications in Australia (1999–2018) EUREKALERT 18/11/20 Solving a mystery: How the TB bacterium develops rapid resistance to antibiotics. For a slow-growing microbe that multiplies infrequently, Mycobacterium tuberculosis, the pathogen that causes tuberculosis (TB) has long puzzled researchers as to how it develops resistance to antibiotics so quickly, in a matter of weeks to months.
Now, TB researchers at San Diego State University have uncovered a crucial clue to the mystery: the answer may lie in the epigenetic domain rather than the genetic domain where most scientists have concentrated their efforts. Their discovery could help advance new diagnostics, therapeutics and vaccine targets. Epigenetics is the study of inheritable changes in gene expression that do not involve a corresponding change to the underlying DNA sequence -- meaning changes to the phenotype but no change in the genotype. This affects only the physical structure of the DNA, through a process called DNA methylation where a chemical 'cap' is added to the DNA molecule, preventing or facilitating the expression of certain genes. Sci Rep. 2019 Mar 14;9(1):4425. A new oligonucleotide array for the detection of multidrug and extensively drug-resistance tuberculosis.
Because of the urgent need to rapidly and accurately diagnose drug-resistant TB, the WHO has recommended the GenoType MTBDRplus and GenoType MTBDRsl tests for detecting resistance to first- and second-line drugs1.
We developed an oligonucleotide array consisting of 60 mutant probes for detecting resistance to 8 anti-TB drugs in 6 to 7 hours. The sensitivity and specificity of the array were comparable to those of the WHO-recommended GenoType MTBDRplus (91.3% and 98.0% for RIF; 89.4% and 98.9 for INH), the GenoType MTBDRsl tests (94.8% and 98.% for FQs; 83.0–91.3% and 94.3–100% for SLIDs), the AID TB resistance LPA (AID Diagnostika, Germany) (100% and 100% for RIF; 97.8% and 100% for INH; 60.0% and 91.7% for EMB; 100% and 96.6% for SM; 33.3% and 98.1% for FQs; 100% and 100% for SLIDs), the Nipro NTM/MDRTB detection kit (Nipro, Japan) (92.4% and 97.5% for RIF; 89.9% and 99.4% for INH) and the Xpert MTB/RIF Ultra (Cepheid, USA)(92.7% and 98.0% for RIF)6,26,27,28,29.

Kayomo, E. Hasker, B.C. de Jong, M. BMC PUBLIC HEALTH 14/09/18 Risk factors for multidrug-resistant tuberculosis among tuberculosis patients in Serbia: a case-control study. Although, Serbia is not a high MDR-TB burden country the study has provided baseline information about factors associated with MDR-TB which can support implementation of targeted interventions to decrease number of cases with MDR-TB.
Among socio-demographic factors, we identified that monthly income of the family ≤100 Euro is a risk factor for development of MDR-TB. It means that cases with lower income had almost four times higher risk of developing MDR-TB than controls. In almost 50% of cases, monthly income of the family of MDR TB cases was equal to level of poverty for Serbia, significantly lower than the corresponding general population . These data are alarming given the circumstances that country does not allocate funds for social welfare payments for these patients.
We found that the default from treatment is statistically significant independent risk factor associated with MDR-TB as confirmed by different studies in different countries [21–23].

Documents CDC. The worldwide epidemic of multidrug-resistant tuberculosis : The Lancet Infectious Diseases. WHO estimates that a third of the world's population is infected with Mycobacterium tuberculosis. In 2009, there were almost 9 million new cases of tuberculosis and the disease killed almost 1 million people around the world. Since the discovery of the BCG vaccine, and the development of new antibiotics in the 1950s, the incidence of tuberculosis has fallen substantially. From 1995 to 2009, about 49 million people received treatment for the disease, 41 million of whom were cured, saving up to 6 million. However, multidrug-resistant (MDR) tuberculosis—ie, resistance to two of the most potent drugs, rifampicin and isoniazid—threatens to turn the tide against the medical advances of the past century. PLOS 16/06/11 Dynamics of Antibiotic Resistant Mycobacterium tuberculosis during Long-Term Infection and Antibiotic Treatment.
For an infecting bacterium the human body provides several potential ecological niches with both internally (e.g. host immunity) and externally (e.g. antibiotic use) imposed growth restrictions that are expected to drive adaptive evolution in the bacterium, including the development of antibiotic resistance. To determine the extent and pattern of heterogeneity generated in a bacterial population during long-term antibiotic treatment, we examined in a monoclonal Mycobacterium tuberculosis infection antibiotic resistant mutants isolated from one patient during a 9-years period.
There was a progressive accumulation of resistance mutations in the infecting clone. Tuberculose humaine. Extensively drug-resistant tuberculosis.
