    Occurrence of Leishmania infantum in Wild Mammals Admitted to Recovery Centers in Spain
    (Pathogens, 2023) Azami Conesa, Iris; Pérez Moreno, Paula; Matas Méndez, Pablo; Sansano-Maestre, Jose; González González, Fernando; Mateo Barrientos, Marta; Gómez Muñoz, María Teresa
    Zoonotic leishmaniasis caused by Leishmania infantum is distributed worldwide and affects humans and domestic and wild mammals. In Europe, specifically in the Mediterranean basin, leishmaniasis is endemic due to the concurrence of the phlebotomine vectors and reservoir mammals, including carnivorous wildlife species and other less studied wild species. In this article, spleen, skin, and eye or oral swabs taken from 134 wild mammals admitted to five wildlife recovery centers in Spain were used. PCR employing fragments of the Repeat region, ITS1, and SSUrRNA were used for detection, and positive samples were processed for sequencing. L. infantum was detected in three out of the nine species analyzed, including European hedgehog, European badger, and red squirrel, with percentages ranging from 11.53 to 35.71%, depending on the species. Most of the species showed higher percentages of positivity in spleen samples than in skin samples. A small number of animals from the remaining six species tested negative, including Algerian hedgehog, stone marten, least weasel, garden dormouse, western polecat, and Egyptian mongoose. Hedgehogs and badgers are good candidates for consideration as epidemiological sentinels and pose a higher risk as potential reservoirs of leishmaniasis based on their percentage of infection and wide distribution.

    West Nile Virus Seroprevalence in Wild Birds and Equines in Madrid Province, Spain
    (Veterinary Sciences, 2024) Williams, Richard Alexander John; Criollo Valencia, Hillary A.; López Márquez, Irene; González González, Fernando; Llorente, Francisco; Jiménez Clavero, Miguel Ángel; Busquets, Núria; Mateo Barrientos, Marta; Ortiz Díez, Gustavo; Ayllón Santiago, Tania
    Simple Summary: West Nile virus (WNV) is a flavivirus that circulates among birds and mosquitoes and can cause outbreaks in people and horses, sometimes leading to serious brain-related illness and death. This study aimed to investigate WNV circulation in birds and horses in Madrid, Spain. Through serological testing (cELISA), a proportion of birds were positive for WNV antibodies, indicating potential exposure. Four birds and one horse were confirmed positive for WNV antibodies with a second test, while four other birds showed antibodies to an undetermined flavivirus. Because birds positive for WNV antibodies were adults, they might have been exposed elsewhere. The horse had previously lived in a WNV endemic zone. The birds positive for flavivirus included two young birds that had not traveled outside Madrid. The presence of antibodies in two juvenile birds that could hardly fly suggests local circulation of flavivirus in birds in Madrid. The study addresses the potential circulation of WNV or related flaviviruses in birds in Madrid, emphasizing the need for increased surveillance to understand transmission dynamics and the principal species involved. Given the growing incidence and spread of WNV in Spain, continued research is vital for risk assessment and implementing effective control measures.
