Swine brucellosis is a zoonotic disease that affects both domestic pigs () and wild pigs such as wild boar (). We evaluated the presence of antibodies against spp. in wild boar hunted in the Campania region, Italy, during the hunting season of 2016-17. Serum samples were collected from 434 wild boars and tested for antibodies against spp. For detection of antibodies to swine brucellosis, the rose Bengal test (RBT) and a blocking enzyme-linked immunosorbent assay (ELISA) were performed. Of 434 serum samples, 22 (5.1%) tested by RBT and 58 (13.5%) tested using the blocking ELISA were positive for brucella. The seroprevalences of spp. did not differ between the sexes or age classes, while the prevalence of infected animals was positively correlated with the Avellino province. Our data showed that wild boar in the Campania region are exposed to brucella infection, and that the prevalence of the disease has increased in recent years.

The body weight-based thrombolytic medication strategy in clinical trials shows critical defects in recanalization rate and post-thrombolysis hemorrhage. Methods for perceiving thrombi heterogeneity of thrombolysis resistance is urgently needed for precise thrombolysis. Here, we revealed the relationship between the thrombin heterogeneity and the thrombolysis resistance in thrombi and created an artificial biomarker-based nano-patrol system with robotic functional logic to perceive and report the thrombolysis resistance of thrombi.

This research aimed to characterize the mitochondrial genome of the Ghoongroo (GH) pig, a notable breed in India, along with its crossbred varieties, to elucidate their matrilineal components, evolutionary history, and implications for conservation. Seven pigs (5 GH, 2 crossbred, namely Rani and Asha) were sequenced for complete mitochondrial genome, while 24 pigs (11 GH, 6 Rani, and 7 Asha) were sequenced for the complete D-loop of the mitochondrial genome. The genome size of these pigs was determined to be 16,690 bp.

Background: Brazilian spotted fever is a tick-borne disease caused by the bacterium Rickettsia rickettsii, whose main vector in Brazil is the tick Amblyomma sculptum. Amplifying hosts are essential for the perpetuation of this bacterium in the tick population as they can be sources of infection during bacteremic periods. Recent studies demonstrated the ability of suids (Sus scrofa) to sustain populations of A.

Domestic pigs (Sus scrofa) raised under natural conditions can show their complete behavioural repertoire. However, rooting behaviour can have a great impact on the environment. In the context of the promotion of farm animal welfare and environmental concerns, this study investigated the potential of nose-clips as a less invasive alternative to nose-rings for the management of rooting behaviour of free-ranging pigs.

is a parasite prevalent in the temperate regions of the vast Palearctic realm, including Iran. In this study, we investigated infection in road-killed animals and carcasses in northern and northeastern Iran by artificial digestion. We assessed species identification and intraspecific genetic diversity using the markers 5S ribosomal DNA intergenic spacer (5S rDNA), internal transcribed spacer I (ITS1), and cytochrome oxidase subunit I ().
