The wild boar, an impactful invasive species in Brazil, is subject to population control activities, which often include the use of hunting dogs. Hunters commonly consume wild boar meat, which is also used to feed their dogs, posing a risk of infection for humans and both and for dogs. The study aimed to investigate the prevalence of infection in wild boars (n = 127) and hunting dogs (n = 73) from São Paulo, Rio Grande do Sul, and Paraná states. We employed histopathological, serological (indirect fluorescent antibody test), and molecular techniques (endpoint polymerase chain reaction). Histopathology slides of wild boar tissue (central nervous system, heart, skeletal muscle, liver, spleen, kidney, gastrointestinal tract, pancreas, lymph nodes, and thyroid) sections revealed no or cysts (0/47). Antibodies anti- were detected in 35/108 (32.4%) and anti- in 45/108 (41.7%) wild boars. Only 2/18 (11.1%) wild boar tissue homogenate samples tested positive for on endpoint PCR. Hunting dogs showed antibodies against in 62/73 (85%) and against in 31/73 (42%). The presence of antibodies against and in wild boars and hunting dogs, along with DNA detection in wild boars, indicates the circulation of these parasites. Educating hunters on preventing these foodborne diseases, including zoonotic risks, is crucial.

Clarifying the inceptive pathophysiology of hypertensive heart disease helps to impede the disease progression. Through coarctation of the infrarenal abdominal aorta (AA), we induced hypertension in minipigs and evaluated physiological reactions and morpho-functional changes of the heart. Moderate aortic coarctation was achieved with approximately 30 mmHg systolic pressure gradient in minipigs.

Ticks are a major concern for both animal and human health, as they are primary vectors of infectious pathogens. This study focused on ticks found in a nature reserve in southern Italy, highly frequented for recreational activities and inhabited by wild boars. Using molecular techniques, 214 ticks, including questing ticks and those removed from wild boars, were examined for tick-borne pathogens (TBPs), with a focus on zoonotic pathogens.

Background: Neospora caninum (Apicomplexa, Sarcocystidae) is a protozoan parasite regarded as a major cause of reproductive failure in cattle. Swine are susceptible to N. caninum infection; however, the role of these animals in the circulation, maintenance, and transmission of N.

Dental anomalies are frequent in boars and pigs, and they generally affect the first premolar loci. The prevalence of these dental anomalies was investigated in a large number of populations around the world. These studies mainly focused on the influence of domestication, size, sexual dimorphism or food hardness on these anomalies.

Background: Gastrointestinal diseases in weaned piglets are a frequent cause of high morbidity and mortality in domestic pigs. The use of antibiotics is problematic due to increasing antibiotic resistance in bacterial populations, for which reason the use of suitable probiotics is highly recommended to maintain animal health and welfare.
Results: In this study, 57 strains of biologically safe lactic acid bacteria (LAB) and bifidobacteria originating from the gastrointestinal tract (GIT) of pigs were identified and characterized in terms of their probiotic properties for potential use in weaned piglets.
