Background: West Nile virus (WNV) is the most widely distributed mosquito-borne flavivirus. Over the past decade, its spread across Europe has raised significant concerns for both public and animal health. Although WNV exposure has been evidenced in various wild mammal species in Spain, no seroepidemiological studies have been conducted on this flavivirus in wild lagomorphs so far.

Although wild lagomorphs are considered one of the major reservoirs of this bacterium, information about the circulation of in European wild rabbit () and Iberian hare () populations in Europe is still very limited. In Spain, is present in northern central regions, with recurrent outbreaks occurring annually.

Evidence of SARS-CoV-2 infections in different animal species raises concerns about the potential for animal reservoirs and transmission to humans. Here, we evaluate the exposure of exotic pet species to this virus throughout the early years of the pandemic (2020 - 2022) in southern Spain. A total of 180 exotic pets (126 domestic rabbits, 31 ferrets, and 23 rodents) were analyzed for antibodies against SARS-CoV-2 using two different ELISAs.

Leishmania infantum is the only endemic pathogenic species in Europe, and exposure to this protozoan has previously been reported in a wide range of wild mammals, including felids.

Although Spain is the country with the highest human incidence of the disease in the European Union, updated data on in ruminants are still limited. A total of 780 serum samples from small ruminants and 605 sera from wild ruminants were collected in the Mediterranean ecosystems of southern Spain during the period 2015-2023.

The European Food Safety Authority (EFSA) has recently prioritized the development of monitoring programs of HEV at different stages of the pig food chain, including outdoor pig farming. Pigs managed under these extensive production systems frequently share habitat and natural resources with wild boar and red deer during fattening stages and cross-species transmission of HEV among these species has previously been suggested.

This pathogen circulates among several wild species in the Iberian Peninsula, however, the role of the Iberian lynx (Lynx pardinus) in the epidemiology of this emerging pathogen is still unknown. The objective of this work was to assess the circulation of C.

Since seroprevalence studies are scarce, at-risk groups are almost unknown. Because blood-borne infections frequently occur in people with drug use, who are particularly vulnerable to infection due to lack of housing and homelessness, this population constitutes a priority in which ratHEV infection should be evaluated.

Since 2013, clinical and fatality cases associated with CCHFV infection have been reported in humans in Spain. During the last few years, endemic circulation of this virus has been detected in ticks and wild ungulates in this country, but the role of other sympatric wild species in the sylvatic cycle of this multi-host virus remains poorly understood.

Detecting susceptible species and potential reservoirs is crucial for preventing the transmission, spread, genetic evolution, and further emergence of viral variants that are major threats to global health. This study aimed to detect exposure or acute infection by SARS-CoV-2 in 420 animals from 40 different wildlife species, including terrestrial and aquatic mammals, from different regions of Spain during the 2020-2023 coronavirus disease 19 (COVID-19) pandemic.

The European wild rabbit () can play a role as a reservoir for this bacterium in certain epidemiological scenarios, but, to date, a very limited numbers of large-scale serosurveys have been conducted for this species worldwide. Although exposure in hare species has also been described, in Iberian hare () has never been assessed.

Although SARS-CoV-2 exposure has been detected in domestic and wild captive animals belonging to Felidae family, surveillance has not been carried out in free-ranging wild felids so far. The aim of the present study was to assess SARS-CoV-2 exposure in the Iberian lynx (Lynx pardinus), the most endangered felid in the world.

We aimed to evaluate the prevalence of ratHEV by measuring viral RNA and specific IgG antibodies in a large Spanish cohort of PLWH.
