The European Union summary report on antimicrobial resistance in zoonotic and indicator bacteria from humans, animals and food in 2022–2023

EFSA Journal, Volume 23, Issue 3, March 2025.
Abstract This report presents the main findings of the 2022–2023 harmonised antimicrobial resistance (AMR) monitoring in Salmonella spp., Campylobacter jejuni and Campylobacter coli from humans and food‐producing animals (broilers, laying hens and fattening turkeys, fattening pigs and cattle under 1 year of age) and derived meat.

Complete Nucleotide Sequence of a Novel Plasmid Bearing the High-Level Tigecycline Resistance Gene tet (X4) [PDF]

Antimicrobial Agents and Chemotherapy, 2019
We reported the complete nucleotide sequence of a tet (X4)-carrying plasmid, pSTB20-1T, from a tigecycline-resistant Escherichia coli isolate in China. Sequence analysis indicated that pSTB20-1T contains a hybrid plasmid backbone and a tet (X4)-containing multidrug ...

The role of the central limit theorem in discovering sharp rates of convergence to equilibrium for the solution of the Kac equation

, 2010
In Dolera, Gabetta and Regazzini [Ann. Appl. Probab. 19 (2009) 186-201] it is proved that the total variation distance between the solution $f(\cdot,t)$ of Kac's equation and the Gaussian density $(0,\sigma^2)$ has an upper bound which goes to zero with ...

Emergence of Mobilized Tigecycline Resistance Gene Cluster tmexCD1-toprJ1 in Raoultella ornithinolytica From a Swine Farm, China

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Tigecycline is considered a last‐line therapeutic option for treating infections caused by multidrug‐resistant (MDR) Gram‐negative bacteria. The emergence of tmexCD1-toprJ1, a plasmid‐mediated resistance‐nodulation‐division (RND) efflux pump gene cluster, poses a growing threat to tigecycline efficacy.

Design, potential and limitations of conjugation‐based antibacterial strategies

Microbial Biotechnology, Volume 17, Issue 11, November 2024.
Highlighting of innovative non‐antibiotic strategies, specifically CRISPR‐based systems delivered via bacterial conjugation. Abstract Over the past few decades, the global spread of antimicrobial resistance has underscored the urgent need to develop innovative non‐antibiotic antibacterial strategies and to reduce antibiotic use worldwide.

Anti-site disorder and improved functionality of Mn$_{2}$Ni{\it X} ({\it X}= Al, Ga, In, Sn) inverse Heusler alloys

, 2014
Recent first-principles calculations have predicted Mn$_{2}$Ni{\it X} ({\it X}=Al, Ga, In, Sn) alloys to be magnetic shape memory alloys. Moreover, experiments on Mn$_{2}$NiGa and Mn$_{2}$NiSn suggest that the alloys deviate from the perfect inverse ...

On the Turaev-Viro endomorphism, and the colored Jones polynomial

, 2012
By applying a variant of the TQFT constructed by Blanchet, Habegger, Masbaum, and Vogel, and using a construction of Ohtsuki, we define a module endomorphism for each knot K by using a tangle obtained from a surgery presentation of K.

HOMFLY polynomials, stable pairs and motivic Donaldson-Thomas invariants [PDF]

, 2012
Hilbert scheme topological invariants of plane curve singularities are identified to framed threefold stable pair invariants. As a result, the conjecture of Oblomkov and Shende on HOMFLY polynomials of links of plane curve singularities is given a Calabi-

Compensatory evolution of chromosomes and plasmids counteracts the plasmid fitness cost

Ecology and Evolution, Volume 14, Issue 8, August 2024.
In this review, we provide a comprehensive overview of the currently reported mechanisms underlying compensatory evolution on chromosomes and plasmids, elucidate key targets regulating plasmid fitness cost, and discuss future challenges in this field.
