Positive epistasis of major low-cost drug resistance mutations rpoB531-TTG and katG315-ACC depends on the phylogenetic background of Mycobacterium tuberculosis strains.

world regions, either as historical endemic, e.g. in East Asia, or recently imported, e.g. in South America, and this family is regarded as the most successful lineage of the global tuberculosis (TB) ...

Genetic elements associated with antimicrobial resistance among avian pathogenic Escherichia coli.

resistance-determining region of gyrA (56.3%). The bla TEM and bla CTX-M-1 genes were the most prevalent among APEC isolates producing extended-spectrum beta-lactamase (ES βL). CONCLUSIONS: These findings provided ...

Evolutionary History and Ongoing Transmission of Phylogenetic Sublineages of Mycobacterium tuberculosis Beijing Genotype in China.

suggested that important Russian B0 / W148 and Asian/Russian A0 /94-32 epidemic clones of the Beijing genotype could trace their origins to the northeastern and northwestern regions of China, respectively. ...

Development of a Luminex xTAG® assay for cost-effective multiplex detection of β-lactamases in Gram-negative bacteria.

probe targeting a conserved 16S rRNA region serving as a DNA extraction control. The assay was optimized using a collection of 48 reference strains and further validated using 105 foodborne ESBL-producing ...

Development and performance assessment of a qualitative SYBR® green real-time PCR assay for the detection of Aspergillus versicolor in indoor air.

versicolor, which is frequently observed in indoor environment and known to be allergenic. The developed primers amplify a short region of the internal transcribed spacer 1 from the 18S ribosomal DNA complex. ...

Seroprevalence of Toxoplasma gondii in domestic sheep in Belgium.

Antwerp (65.2%) and Wallonia (68.6%) are statistically lower than in the other regions in Belgium (96.7-97.8%) (P <0.05). The present study is the first report that analyzed the prevalence of T. gondii ...

Characterization of suspected illegal skin whitening cosmetics.

décolleté for local depigmentation of hyper pigmented regions or more importantly, for a generalized reduction of the skin tone. These cosmetic products are suspected to contain illegal active substances that ...

Neonatal thyroid-stimulating hormone concentrations in Belgium: a useful indicator for detecting mild iodine deficiency?

neonatal TSH is useful to detect severe iodine deficiency, it should not be recommended presently for the evaluation of iodine status in mildly iodine deficient regions. Health Topics:  Food consumption and ...

Does a small difference in iodine status among children in two regions of Belgium translate into a different prevalence of thyroid nodular diseases in adults?

Nodule Thyroidectomy Abstract: PURPOSE: To explore whether there are regional differences in iodine status and in prevalence of thyroid diseases in the two main regions of Belgium. METHODS: A national ...

Human biomonitoring on heavy metals in Ath: methodological aspects.
