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

clustering was higher in modern versus ancient Beijing strains (35.9% vs. 12.1%; P  <0.001). After taking into consideration the presence of rpoB and katG mutations, clustering decreased to 15.9% in modern ...

Model-Based Classification for Digital PCR: Your Umbrella for Rain.

reduces accuracy, the uncertainty of this classification is typically ignored. We introduce a model-based clustering method to estimate the probability that the target is present (absent) in a partition ...

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

The higher clustering of the modern isolates in children and lack of increased MDR rate in any sublineage suggest that not association with drug resistance but other (e.g., speculatively, ...

Compensatory Mutations of Rifampin Resistance Are Associated with Transmission of Multidrug-Resistant Mycobacterium tuberculosis Beijing Genotype Strains in China.

tandem-repeat clustering (P = 0.016). In summary, we believe that these findings indirectly suggest an epistatic interaction of particular mutations related to RIF resistance and strain fitness and, consequently, ...

Serological profiles in nursery piglets colonized with Staphylococcus aureus.

Corporation). Though antibody responses showed broad inter-individual variability, serological results appeared to be clustered by litter of origin. For most antigens, an age-related response was observed with an ...

Lessons learned from the management of a national outbreak of Salmonella ohio linked to pork meat processing and distribution.

years of age, and 22 adults > 65 years of age) were affected. The isolates were distributed throughout Belgium but a cluster of several cases was observed around Brussels. At the same time, an increase ...

Microbiological and molecular investigation of an increase of human listeriosis in Belgium, 2006-2007.

Assessment Risk Factors Abstract: In Belgium, the majority of cases of listeriosis are sporadic cases. In this study we present evidence for an episode of listeriosis: a time-linked cluster of cases that ...
