First genetic characterisation of multidrug-resistant Mycobacterium tuberculosis isolates from Algeria

ConclusionsResistant MTB isolates in Algeria harbour resistance genotypes similar to other countries, but some rare patterns may result from selection and transmission processes inherent to the country.

Martinson, Ebrahim VariavaAbstractSettingTshepong Hospital multidrug resistant (MDR) unit between April 2011 and February 2014.ObjectiveRifampicin resistant (RR) tuberculosis (TB) on X-pert MTB/Rif is assumed a surrogate for MDR TB. Following a RR result, a second specimen is taken for confirmatory culture and drug susceptibility testing (DST). We compare the initial diagnostic X-pert MTB/RIF result to the confirmatory DST in a high HIV...

Conclusion: Our work demonstrates the utility of machine learning as a flexible approach to drug resistance prediction that is able to accommodate a much larger number of predictors and to summarize their predictive ability, thus assisting clinical decision making and single nucleotide polymorphism detection in an era of increasing WGS data generation.

ConclusionsIn recent years, we identified a low incidence of DR-TB as well as the poor outcome of DR-TB treatment. The majority of cases were primary drug-resistant and foreign-born. To further improve treatment outcome, special attention should be given to the high-risk DR-TB patients.

ConclusionOverexpression of EP genes can contribute to the emergence of a MDR phenotype in M. tuberculosis. Inhibition of EPs may provide a promising strategy for improving tuberculosis treatment outcomes in patients infected with M/XDR-TB isolates.

In this study, a BER homolog encoded by cj0595c (named nth) in C. jejuni was analyzed for endonuclease III activity and for its role in maintaining genomic stability. It was found that inactivation of nth resulted in elevated frequencies of spontaneous fluoroquinolone-resistant (FQR) and oxidative stress resistant (OXR) mutants, compared with the wild-type strain in C. jejuni. Sequencing analysis of the FQR and OXR mutants revealed that the elevated mutation rates were associated with C → T or G → A transition in gyrA (FQR mutants) or perR (for OXR mutants). In an in vitro assay, a purified recombinant C. jejuni ...
