Wild animals are recognized as significant reservoirs for various zoonotic pathogens, including antibiotic-resistant bacteria. This study aimed to investigate the presence of spp. strains in fallow deer () inhabiting a natural preserve in Central Italy and to examine the phenotypic and genotypic antimicrobial resistance and the presence of some virulence genes among the isolates.

Nineteen chromene-hydrazone derivatives containing a variety of structural modifications on the hydrazone moiety were synthesized. Structure-activity correlations were investigated to determine the influence of structural variations on anti-ferroptosis, anti-quorum sensing, antibacterial, DNA cleavage and DNA binding properties. Ferroptosis inhibitory activity was determined by measuring the ability of the derivatives to reverse erastin-induced ferroptosis.

The aim of the study was to assess which kill site characteristics were selected by a lone wolf living in a protected Mediterranean coastal area near the city of Pisa, Italy, where both wild and domestic ungulates were available as potential prey. Between 2017 and 2019, we monitored the wolf's predatory behaviour through a combination of camera trapping and active search for kill sites and prey carcasses. The main prey found was the fallow deer (n = 82); only two wild boars and no domestic ungulates were found preyed upon.

Antimicrobial compounds can combat microbes through modulating host immune defense, inhibiting bacteria survival and growth, or through impeding or inhibiting virulence factors. In the present study, a panel of substituted diphenyl amide compounds previously found to disrupt bacterial quorum sensing were investigated and several were found to promote survival in the model when provided therapeutically to treat a Gram-positive bacterial infection from methicillin-resistant strain MW2. Out of 21 tested compounds, -4-Methoxyphenyl-3-(4-methoxyphenyl)-propanamide (AMI 82B) was the most potent at disrupting .

The ability to update predictive relationships and adjust behavior accordingly is critical for survival. Females take longer to update expectancies under conditions of outcome omission. It remains unknown whether that is also the case under conditions when outcomes are delivered such as in overexpectation.
