Domestic Cat Hepadnavirus Infection in Iberian Lynxes.

We conducted a survey for domestic cat hepadnavirus, an analog of human hepatitis B virus, in the endangered felid species Iberian lynx. Results revealed specific antibodies in 32.3% of serum samples and DNA in 0.

Exposure to West Nile Virus in Wild Lagomorphs in Spanish Mediterranean Ecosystems.

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.

in Wild Lagomorphs in Southern Spain's Mediterranean Ecosystems.

is a vector-borne zoonotic bacterium that causes tularemia, a disease of great importance for animal and public health. 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.

Assessment of SARS-CoV-2 exposure in exotic pets in Spain.

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.

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.

Monitoring of Leishmania infantum exposure in the Iberian lynx (Lynx pardinus).

Leishmaniosis, caused by phlebotomine sand fly-borne Leishmania spp., is a multi-host and zoonotic disease in tropical, subtropical and temperate climates, worldwide. 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.

Seroepidemiology of in Domestic and Wild Ruminant Species in Southern Spain.

The European Food Safety Authority has recently listed Q fever as a priority for setting up a coordinated surveillance system. 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.

Re-emergence of Bagaza virus in wild birds from southern Spain.

Bagaza virus (BAGV; Orthoflavivirus bagazaense) is an emerging vector-borne flavivirus affecting avian species with severe implications for animal health, and whose zoonotic potential has also been suggested. The aim of the present study was to monitor the epidemic outbreak of BAGV in wild birds from Spain in 2021. BAGV cases were confirmed in game bird species, including red-legged partridges (Alectoris rufa) and common pheasants (Phasianus colchicus) from 24 hunting areas.

Longitudinal survey of hepatitis E virus in extensively raised pigs in Spain.

Hepatitis E virus (HEV) is an emerging zoonotic virus of public health concern, of which pigs, wild boar and red deer are the main reservoirs. 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.

Monitoring of Coxiella burnetii in the Iberian lynx (Lynx pardinus).

Coxiella burnetii is a multi-host bacterium of major public and animal health concern. 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.

Absence of Crimean-Congo hemorrhagic fever virus in wild lagomorphs and their ticks in Spanish Mediterranean ecosystems.

Crimean-Congo hemorrhagic fever virus (CCHFV) is an emerging tick-borne pathogen in different European countries. 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.

Survey of severe acute respiratory syndrome coronavirus 2 in captive and free-ranging wildlife from Spain.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), considered a zoonotic agent of wildlife origin, can infect various animal species, including wildlife in free-range and captive environments. 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.

Movement-driven modelling reveals new patterns in disease transmission networks.

Interspecific interactions are highly relevant in the potential transmission of shared pathogens in multi-host systems. In recent decades, several technologies have been developed to study pathogen transmission, such as proximity loggers, GPS tracking devices and/or camera traps. Despite the diversity of methods aimed at detecting contacts, the analysis of transmission risk is often reduced to contact rates and the probability of transmission given the contact.

Serosurvey of Blood Donors to Assess West Nile Virus Exposure, South-Central Spain.

We analyzed West Nile Virus (WNV) exposure from 1,222 blood donors during 2017-2018 from an area of south-central Spain. Results revealed WNV seroprevalence of 0.08% (95% CI 0.
