Brain samples were collected within the project "CWD Risk in Portugal", profiOng the infecOous diseases epidemiological surveillance and screening of chronic wasOng disease (CWD) during cervids hunts. The literature on wild animals´ neuropathological lesions is scarse. This work aims to describe the neuropathological findings in samples collected in deer hunted in Portugal.
Among the transmissible spongiform encephalopathies (TSEs), chronic wasting disease (CWD) in cervids is now a rising concern in wildlife within Europe, after the detection of the first case in Norway in 2016, in a wild reindeer and until June 2022 a total of 34 cases were described in Norway, Sweden and Finland. The definite diagnosis is post-mortem, performed in target areas of the brain and lymph nodes. Sampl...
Increased oxidative stress (OS) and depletion of nigrostriatal dopamine (DA) are closely linked to the neurodegeneration observed in Parkinson’s Disease (PD). Caffeic acid (CA)-based antioxidants were developed, and their inhibitory activities towards monoamine oxidases (MAOs) and catechol O-methyltransferases (COMT) were screened. The results showed that the incorporation of an extra double bond maintained or ...

Chronic wasting disease risk assessment in Portugal: results and future work.
Among the transmissible spongiform encephalopathies (TSEs), chronic wasting disease (CWD) in cervids is now the rising concern in wildlife within Europe, after the first case was detected in Norway in 2016, in a wild reindeer and until October 2021, a total of 34 cases were described in Norway, Sweden and Finland.
Transmissible Spongiform Encephalopathy (TSE) or prion diseases are a family of neurodegenerative diseases caused by lethal infectious pathogens called Prions. Among the transmissible spongiform encephalopathies (TSEs), chronic wasting disease (CWD) in cervids is now the rising concern in wildlife within Europe, after the first case was detected in Norway in 2016, in a wild reindeer and until October 2021, a to...
Among the Transmissible Spongiform Encephalopathies, Chronic Wasting Disease (CWD) in cervids is now the rising concern in wildlife within Europe after the first case detected in Norway in 2016. CWD shows a notable horizontal transmission, affecting both free-ranging and captive cervids. Furthermore, several genetic variants in the Prion Protein (PRNP) gene coding sequence of the cervid were identified, which i...
The chronic wasting disease (CWD) in cervids is now a rising concern in wildlife within Europe, since the first case detected in Norway in 2016, 40 more appear until May of 2022, in Norway, Sweden and Finland. The unclear origin of these new European cases and the risk that CWD poses to cohabiting ani-mals or more importantly to humans is largely unknown, is very important for the establishment of risk assessme...
Given its geographic isolation, and after the last glaciation, the Iberian Peninsula, become a sanctuary of plants and animal’s diversification, being considered a hotspot of genetic diversity specially for mammal species. The roe deer (Capreolus capreolus - CCR), an herbivore ungulate, has a widespread geographical distribution which extends from the Iberian Peninsula to the north of Scandinavia, being found a...
