Harnessing efficient multiplex PCR methods to detect the expanding Tet(X) family of tigecycline resistance genes

Virulence, 2020
A growing number of tet(X)-type tigecycline resistance determinants [tet(X1) to tet(X5)] constitutes an expanding family of tetracycline-inactivating enzymes, posing a potential risk to global public health.

Identification of novel tetracycline resistance gene tet(X14) and its co-occurrence with tet(X2) in a tigecycline-resistant and colistin-resistant Empedobacter stercoris

Emerging Microbes and Infections, 2020
Tigecycline is one of the last-resort antibiotics to treat severe infections. Recently, tigecycline resistance has sporadically emerged with an increasing trend, and Tet(X) family represents a new resistance mechanism of tigecycline.

More diversified antibiotic resistance genes in chickens and workers of the live poultry markets

Environment International, 2021
Background: Poultry farms and LPMs are a reservoir of antimicrobial resistant bacteria and resistance genes from feces. The LPM is an important interface between humans, farm animals, and environments in a typical urban environment, and it is considered ...

A tetrahedral space-filling curve for non-conforming adaptive meshes

, 2016
We introduce a space-filling curve for triangular and tetrahedral red-refinement that can be computed using bitwise interleaving operations similar to the well-known Z-order or Morton curve for cubical meshes.

Hybrid copula mixed models for combining case-control and cohort studies in meta-analysis of diagnostic tests [PDF]

, 2016
Copula mixed models for trivariate (or bivariate) meta-analysis of diagnostic test accuracy studies accounting (or not) for disease prevalence have been proposed in the biostatistics literature to synthesize information.

Novel IS26-mediated hybrid plasmid harbouring tet(X4) in Escherichia coli

Journal of Global Antimicrobial Resistance, 2020
Objectives: As the spread of antimicrobial resistance genes becomes an increasing global threat, improved understanding of genetic structure and transferability of the resistant plasmids becomes more critical.

Environmental surveillance of ESBL and carbapenemase-producing gram-negative bacteria in a Ghanaian Tertiary Hospital

Antimicrobial Resistance and Infection Control, 2022
Background The burden of antibiotic resistant infection is mainly felt in low-to-middle income countries, where the rate of antimicrobial resistance is largely under-surveyed and under huge pressure from unregulated, disparate and often self-guided ...

Analytic formulas for complete hyperbolic affine spheres [PDF]

, 2013
We classify all regular three-dimensional convex cones which possess an automorphism group of dimension at least two, and provide analytic expressions for the complete hyperbolic affine spheres which are asymptotic to the boundaries of these cones.

THz time-domain spectroscopy of mixed CO2–CH3OH interstellar ice analogs [PDF]

, 2016
The icy mantles of interstellar dust grains are the birthplaces of the primordial prebiotic molecular inventory that may eventually seed nascent solar systems and the planets and planetesimals that form therein.
