Polystyrene microplastic exposure modulates gut microbiota and gut-liver axis in gilthead seabream (Sparus aurata).

Microplastics (MPs) are a threat of growing concern for living organisms as they exist in all ecosystems. The bidirectional communication between the gut, its microbiota, and the liver, has been conceptualized as gut-liver axis and may be influenced by environmental factors. MPs can cause intestinal and hepatic injuries, but there is still limited research exploring their impact on gut-liver axis.

Pine needle abortions in cattle due to consumption of Pinus ponderosa in Argentina: Case reports.

Two outbreaks of pine needle abortions in cattle are here reported for the first time in Argentina. The cases occurred in Chubut and Neuquén provinces in the Patagonia region, causing 29.6% and 9% of abortions in each herd respectively.

Antimicrobial activity of lipids extracted from Hermetia illucens reared on different substrates.

As the problem of antimicrobial resistance is constantly increasing, there is a renewed interest in antimicrobial products derived from natural sources, particularly obtained from innovative and eco-friendly materials. Insect lipids, due to their fatty acid composition, can be classified as natural antimicrobial compounds. In order to assess the antibacterial efficacy of Hermetia illucens lipids, we extracted this component from the larval stage, fed on different substrates and we characterized it.

Exhibits Interindividual Differences in Behavioural and Problem-Solving Performance.

By presenting individual with an extractive foraging problem with a puzzle box, we examined the possible correlation between behavioural performances (e.g., ease of adaptation to captive conditions, prevalence of neophobic and neophilic behaviours, and propensity to learn individually or by observing conspecifics), biotic (body and brain size, age, sex) and abiotic (seasonality and place of origin) factors.

Occurrence and Antimicrobial Resistance of Isolated from Healthy Pet Rabbits.

is a ubiquitous microorganism and an opportunistic pathogen responsible for numerous diseases in humans and animals, characterized by different clinical pictures with acute or subacute course. , due to its great adaptability and versatility in terms of infections and hosts, can be considered a relevant pathogen because of the harmful effects on animal health and its potential for transmission from animals to humans and vice versa. In recent years, a marked increase in multidrug-resistant has been reported, posing a serious threat for disease management, food safety, and animal and human health as they limit available therapeutic options.
