Canine leishmaniosis (CanL) caused by Leishmania infantum is a widespread endemic disease in the Mediterranean basin, though, so far, north of Spain has been considered non-endemic area. The aim present study was to determine prevalence specific antibodies L. among stray dogs living shelters this area, and evaluate clinical status (both signs clinico-pathological abnormalities) seropositive dogs. Besides infection, epidemiological role variables like sex, breed age also assessed. Over year...
Since 2009, the incidence of human leishmaniosis in SW Madrid region has been unusually high. Although dogs are main reservoir for this disease, a role played by outbreak ruled out and investigators now considering other hosts (eg. cats, rabbits, hares) as possible alternative reservoirs. This study was designed to examine Leishmania infantum status stray cats assess its implications outbreak. 346 captured were tested antibodies against L. indirect fluorescent antibody technique (IFAT)...
This report describes L. infantum infection seroprevalence in dogs Spain through data obtained from peer-reviewed literature and a cross-sectional serological survey assessing epidemiological habitat variables as risk factors for infection.

Canine leishmaniosis (CanL) has been in the spotlight since 2009 outbreak of human Madrid. In framework Leishmaniosis Surveillance Programme set up Madrid, this study examines Leishmania-specific seroprevalences stray dogs for area and rest Madrid region over period spanning from to present (2009–2016). These data are interest because could be sentinels disease surveillance endemic areas. Since 2011, we have also monitoring owned area. Over period, Leishmania infantum seroprevalence was...
Introduction Coronavirus disease 2019 (COVID-19) is an infectious zoonotic caused by SARS-CoV-2. Monitoring the infection in pets recommended for human surveillance, prevention, and control since virus can spread from people to animals during close contact. Several diagnostic tests have been adapted humans animals, but limited data on validation process are available. Methods Herein, first comparative study of six “ house ” two commercial serological developed monitor SARS-CoV-2 was...
Abstract Background In recent years, cases of leishmaniosis have been described in animals housed captivity zoos Spain [Bennett’s wallaby ( Macropus rufogriseus ), orangutan Pongo pygmaeus pygameus and European otter Lutra lutra )]. Some these zoological parks are endemic areas for both human animal leishmaniosis, thus it should be very important to include this zoonosis the differential diagnosis. Methods The study was carried out two Madrid, Madrid Zoo Faunia, analyzed seven meerkats....
The Iberian population of the European wildcat (Felis silvestris) is undergoing a decline and highly fragmented. This study aimed to determine occurrence identity tick-borne parasites (piroplasms Hepatozoon spp.) in Navarre, one strongholds for wildcats Spain.
