Free-Ranging Wolves (Canis lupus) are Natural Reservoirs of Intestinal Microeukaryotes of Public Health Significance in Southwestern Europe.

Introduction: Intestinal microeukaryote parasites are major contributors to the burden of diarrhoea in humans and domestic animals, but their epidemiology in wildlife is not fully understood. We investigated the frequency, genetic diversity and zoonotic potential of protists of animal and public health significance in free-ranging grey wolf (Canis lupus) populations in south-western Europe.

Methods: Individually formed faecal samples collected from necropsied wolves or scat trails in Italy (n = 47), Portugal (n = 43) and Spain (n = 225) during the period 2011-2023 were retrospectively analysed using molecular (PCR and Sanger sequencing) methods.

Molecular detection and characterization of Blastocystis in herbivore livestock species in Portugal.

Blastocystis is a ubiquitous intestinal protist in humans and animals worldwide. The traditional livestock free-roaming raising system in rural communities increases the risk of infection with contact with a wider range of pathogens transmitted via the faecal-oral route associated with that wildlife-livestock-human interface. However, no studies have been conducted to determine the occurrence and subtype distribution of Blastocystis in livestock in Portugal.

Occurrence and molecular characterization of Enterocytozoon bieneusi in wild and domestic animal species in Portugal.

The phylum Microsporidia encompasses a diverse group of obligate, intracellular, and spore-forming organisms able to infect a wide range of animal hosts. Among them, Enterocytozoon bieneusi is the most frequently reported species in humans and animals. Little is known about the presence and epidemiology of E.

Endoparasites of the Iberian wolf (Canis lupus signatus) and mesocarnivores in Central Portugal.

At the end of the nineteenth century, massive population declines were observed in carnivores due to the emergence of infectious diseases. This study aims to investigate, by means of coprological analysis, the prevalence and intensity of the parasites that infect the endangered Iberian wolf Canis lupus signatus and two mesocarnivores (the red fox Vulpes vulpes and the stone marten Martes foina) in Central Portugal. In total, 67.

Unravelling the Diversity and Abundance of the Red Fox () Faecal Resistome and the Phenotypic Antibiotic Susceptibility of Indicator Bacteria.

The WHO considers that antimicrobial resistance (AMR) is among the ten greatest global public health risks of the 21st century. The expansion of human populations and anthropogenically related activities, accompanied by the fragmentation of natural habitats, has resulted in increased human-wildlife interaction. Natural ecosystems are therefore subjected to anthropogenic inputs, which affect the resistome of wild animals.

Climate and landscape changes as driving forces for future range shift in southern populations of the European badger.

Human-Induced Rapid Environmental Change (HIREC), particularly climate change and habitat conversion, affects species distributions worldwide. Here, we aimed to (i) assess the factors that determine range patterns of European badger (Meles meles) at the southwestern edge of their distribution and (ii) forecast the possible impacts of future climate and landcover changes on those patterns. We surveyed 272 cells of 5 × 5 km, to assess badger presence and confirmed its occurrence in 95 cells (35%).
