Brain-Derived Neurotrophic Factor, Kynurenine Pathway, and Lipid-Profiling Alterations as Potential Animal Welfare Indicators in Dairy Cattle.

Complete animal welfare evaluation in intensive farming is challenging. With this study, we investigate new biomarkers for animal physical and mental health by comparing plasma expression of biochemical indicators in dairy cows reared in three different systems: (A) semi-intensive free-stall, (B) non-intensive tie-stall, and (C) intensive free-stall. Additionally, protein levels of mature brain-derived neurotrophic factor (mBDNF) and its precursor form (proBDNF) and indoleamine 2,3-dioxygenase (IDO1) specific activity were evaluated in brain samples collected from 12 cattle culled between 73 and 138 months of age.

Detailed epitope mapping of SARS-CoV-2 nucleoprotein reveals specific immunoresponse in cats and dogs housed with COVID-19 patients.

Since the initial emergence in December 2019, the novel Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has been reported in over 200 countries, representing an unprecedented challenge related to disease control worldwide. In this context, cases of human to animal transmission have been reported, raising concern about the potential role of companion animals in the pandemic and stressing the need for reliable animal testing. In the study, a detailed epitope mapping of SARS-CoV-2 nucleoprotein, using both human and pet sera, allowed the identification of the most antigenic region in the C-terminus domain of the protein, which was used to develop an experimental double antigen-based ELISA.

Goat Paratuberculosis: Experimental Model for the Evaluation of Mycobacterium Persistence in Raw Milk Cheese.

subsp. s (MAP) is the causative agent of chronic proliferative enteritis found in ruminants, known as paratuberculosis (PTB). The spread of PTB is increasing in countries with advanced animal husbandry practices, leading to significant economic losses.

First detection of an Italian human-to-cat outbreak of SARS-CoV-2 Alpha variant - lineage B.1.1.7.

The emergence of new SARS-CoV-2 variants and their rapid spread pose a threat to both human and animal health and may conceal unknown risks. This report describes an Italian human-to-cat outbreak of SARS-CoV-2 lineage B.1.

Beware of dogs! Domestic animals as a threat for wildlife conservation in Alpine protected areas.

Diseases are natural regulating factors of wildlife populations, but some pathogens may become an important threat in wildlife conservation, especially for endangered species. The presence of domestic animals may foster the spread of diseases in natural population, although their role in the dynamic of infections in wildlife is not clear. In this study, we investigated the presence and prevalence of a range of multi-host pathogens in wild species (red fox, Eurasian badger, beech marten, pine marten, stoat for a total of 89 carcasses analysed) and domestic animals ( = 52 shepherd and  = 25 companion dogs) living in a protected area of the Alps (the Gran Paradiso National Park) and discussed the role of domestic dogs as possible source of infection for wild species.

Long-Term Assessment of Baseline Blood Biochemistry Parameters in Rainbow Trout () Maintained under Controlled Conditions.

Twelve biochemical parameters were measured in serum blood samples from rainbow trout () maintained under controlled conditions. Forty-five samples were taken every 3 months (T1-T4) over the course of one year to define baseline values. The effect of fish total weight (TW) was also evaluated.

Motor neuron degeneration, severe myopathy and TDP-43 increase in a transgenic pig model of SOD1-linked familiar ALS.

Amyotrophic Lateral Sclerosis (ALS) is a neural disorder gradually leading to paralysis of the whole body. Alterations in superoxide dismutase SOD1 gene have been linked with several variants of familial ALS. Here, we investigated a transgenic (Tg) cloned swine model expressing the human pathological hSOD1 allele.

Effect of farming system on donkey milk composition.

Background: Donkey milk is considered as a functional food for sensitive consumers, such as children who are allergic to cow milk. No information is available regarding the effect of farming systems on the quality of donkey milk. The present study aimed to evaluate the effect of the farming system and lactation stage on donkey milk with respect to gross composition, as well as fat-soluble vitamins and fatty acids (FA).

Detection of Leptospira spp. in Water Turtle (Trachemys scripta) Living in Ponds of Urban Parks.

Urban parks are green areas of cities where families and children spend hours outside. Turtles often inhabit urban parks. However, even if the animals seem harmless, they may serve as both reservoirs or accidental hosts for different serotypes of spp.

Epidemiologic survey for Brucella suis biovar 2 in a wild boar (Sus scrofa) population in northwest Italy.

In 2001, antibodies to Brucella spp. were detected in the wild boar (Sus scrofa) population of Regional Park in the Piedmont, northwest Italy. This was the first report of swine brucellosis in Italian wildlife, and in response, we conducted a survey on wild boars culled in the park to evaluate the presence and epidemiologic pattern of Brucella.
