Antimicrobial Susceptibility of Commensal Isolated from Wild Birds in Umbria (Central Italy).

The role of wildlife, including birds, in antimicrobial resistance is nowadays a speculative topic for the scientific community as they could be spreaders/sources of antimicrobial resistance genes. In this respect, we aimed to investigate the antimicrobial susceptibility of 100 commensal strains, isolated from wild birds from an Umbrian rescue centre and admitted to the Veterinary Teaching Hospital of Perugia (Central Italy) mainly for traumatic injuries. The possible presence of spp.

-Mediated Colistin Resistance and Genomic Characterization of Antimicrobial Resistance in ESBL-Producing Infantis Strains from a Broiler Meat Production Chain in Italy.

This work aimed to evaluate phenotypically and genotypically the colistin susceptibility of 85 Infantis strains isolated in Italy from the broiler production chain, and to apply a whole-genome approach for the determination of genes conferring antimicrobial resistance (AMR). All isolates were tested by the broth microdilution method to evaluate the colistin minimum inhibitory concentrations (MICs). A multiplex PCR was performed in all isolates for the screening of , , , genes and whole-genome sequencing (WGS) of six .

Antimicrobial Susceptibility of and ESBL-Producing Diffusion in Conventional, Organic and Antibiotic-Free Meat Chickens at Slaughter.

As a result of public health concerns regarding antimicrobial resistance in animal-based food products, conventional poultry companies have turned to 'raised without antibiotics' (ABF) and organic farming systems. In this work, we evaluated the influence of rearing systems on antimicrobial susceptibility in and extended-spectrum β-lactamase (ESLB) diffusion in conventional (C), organic (O) and antibiotic free (ABF) chicken samples collected from cloacal swabs and skin samples in slaughterhouse. The isolates from conventional (135), antibiotic-free (131) and organic (140) samples were submitted to the Kirby-Bauer method and ESBL were analyzed by the microdilution test.

Immuno- and glyco-histochemistry as a tool to evaluate the oregano supplemented feed effects in pig gut.

Among oregano properties, its antioxidant and antibacterial effects are particularly interesting. Oregano is also able to induce a higher glycoconjugate production in gut, creating a physical barrier against microorganisms. This study evaluated the effects of adding an aqueous extract of oregano (OAE) to the diet of two homogenous groups of pigs during the finisher phase.
