Wastewater-based surveillance in Italy leading to the first detection of mcr-10-positive Klebsiella quasipneumoniae.

Wastewater-based surveillance enabled the first detection of the mobile colistin resistance gene mcr-10 in Italy. This plasmid-borne resistance gene was found in strains of Klebsiella quasipneumoniae isolated from samples of human raw sewage collected over several months. Although the isolates were phenotypically susceptible to colistin, the emergence of mcr-10 is concerning due to the highly variable expression of the gene and the potential for horizontal transfer to other species.

Extended-Spectrum-β-Lactamase- and AmpC-Producing in Domestic Dogs: Spread, Characterisation and Associated Risk Factors.

In veterinary medicine, the issue of antimicrobial resistance was mainly addressed in food-producing animals (although companion animals also deserve attention). Indeed, these species may be reservoir of resistant microorganisms, such as extended-spectrum β-lactamase and AmpC (ESBL/AmpC)-producing bacteria. Dogs in particular may transmit them to close-contact humans.

Antimicrobial Resistance of in Dairy Calves: A 15-Year Retrospective Analysis and Comparison of Treated and Untreated Animals.

The health problem of antimicrobial resistance (AMR) involves several species. AMR surveillance is essential to identify its development and design control strategies; however, available data are still limited in some contexts. The AMR profiles of 2612 strains isolated over a period of 15 years (2002-2016) from calf enteric cases were analyzed to determine the presence of resistance and their temporal dynamics.

ESBL/AmpC-Producing in Wild Boar: Epidemiology and Risk Factors.

The complex health problem of antimicrobial resistance (AMR) involves many host species, numerous bacteria and several routes of transmission. Extended-spectrum β-lactamase and AmpC (ESBL/AmpC)-producing are among the most important strains. Moreover, wildlife hosts are of interest as they are likely antibiotics free and are assumed as environmental indicators of AMR contamination.

Pathogenicity of Shiga Toxin Type 2e in Pig Colibacillosis.

Shiga toxin type 2e (Stx2e) is the causative factor of diarrhea and edema in swine. The aims of this study were to determine the prevalence of Stx2e-producing isolates and to characterize isolates from clinical cases of pig colibacillosis and healthy swine. During the 11 years of the study (2006-2017), a total of 233 Stx2e-producing isolates were detected-230 out of 2,060 (11.
