Item Forensic findings in urban red fox mortality in the metropolitan area of Madrid, 2014–2022(Journal of Veterinary Diagnostic Investigation, 2024) Rebollada Merino, Agustín Miguel; Bárcena Asensio, María Carmen; Porras González, Néstor; Domínguez Rodríguez, Lucas José; Rodríguez Bertos, Antonio ManuelThe expanding presence of red foxes ( Vulpes vulpes) in urban and suburban regions could potentially lead to increased instances of human aggression towards this species. We studied 10 deceased red foxes that were submitted by law enforcement agencies in the metropolitan area of Madrid in 2014–2022 because of suspected abuse. Forensic autopsies were performed to establish the cause and manner of death. In 4 of the 10 cases, the cause of death was deemed unnatural, involving blunt-force trauma ( n = 2), asphyxia resulting from hanging ( n = 1), and firearm injury ( n = 1). Among the remaining cases, most had succumbed to natural causes ( n = 4), often marked by severe emaciation and a high burden of parasites, primarily Sarcoptes scabiei. In 2 cases, death was undetermined given the poor preservation of the carcass. The growing prevalence of wildlife species in urban areas, particularly red foxes, may require forensic veterinary investigation of deaths potentially related to abuse.Item Effects on Intestinal Mucosal Morphology, Productive Parameters and Microbiota Composition after Supplementation with Fermented Defatted Alperujo (FDA) in Laying Hens(Antibiotics, 2019) Rebollada Merino, Agustín Miguel; Bárcena Asensio, Carmen; Ugarte Ruiz, María; Porras González, Néstor; Mayoral Alegre, Francisco Jesús; Tomé Sánchez, Irene; Rodríguez Bertos, Antonio Manuel; Domínguez Rodríguez, Lucas JoséThe olive oil sector is currently adapting its traditional function to also become a supplier of high-value by-products that possess antioxidant, anti-inflammatory and antimicrobial properties. In this study, we evaluated the effect of the fermented defatted alperujo (FDA) on the intestinal health of laying hens. The morphology of the duodenal and cecal mucosa, the composition of the intestinal microbiota and the productivity of a batch of laying hens were evaluated after FDA supplementation. At early life stages, significant differences (p < 0.001) were observed in duodenal villi height and in crypt depth of both the duodenum and the cecum in the FDA-supplemented group, indicating improved intestinal health in this group. Microbiota composition in the hatchery group supplemented with FDA had a higher abundance of Actinobacteria, Firmicutes and Proteobacteria, and higher bacterial diversity. During the production period, significant differences (p < 0.05) were observed in the number of broken eggs from the supplemented group. We conclude that FDA supplementation improves the absorption capacity of the intestinal mucosa and modifies the intestinal microbiota to favor a greater immune response, leading to an increase in egg production.Item Forensic investigations of religious rituals involving poultry: a case report(Journal of Comparative Pathology, 2023) Vázquez Fernández, Esther; Rebollada Merino, Agustín Miguel; Chinchilla Rodríguez, Blanca; Porras González, Néstor; Rodríguez Bertos, Antonio ManuelAnimal victims of human cruelty are receiving increasing attention from the press and society. Veterinary pathologists and civic authorities have a duty not only to elucidate the cause, method and manner of death but also to address the motivation behind a case. Poultry are commonly used as offering to gods in Santería rituals (ebós). Only a few cases have been reported in scientific journals, in contrast with the number of cases described in the media. Here, a hen and a cockerel (Gallus domesticus) were submitted to the VISAVET Health Surveillance Centre for autopsy, which comprised macroscopic and histological studies and microbiological testing for Chlamydia psittaci, avian orthoavulavirus 1 (Newcastle disease virus), West Nile virus and avian influenza virus. The carcasses were in an active decay stage of decomposition, containing larvae of Lucilia eximia. Both animals had been decapitated and haemorrhages in the cutting region were observed histologically. Post-mortem burns were also observed. To the best of the authors’ knowledge, this is the first post-mortem description of lesions in a domestic avian species due to religious rituals. European Union and Spanish forensic practitioners should be aware that these ritual sacrifices occur in some European countries. Moreover, future European and national legislation updates should consider this type of animal abuse.- Project number: 163
Item Transparencia en la calidad docente: reflexión solidaria intradepartamental de las evaluaciones obtenidas en las encuestas del estudiantado del programa docentia. Análisis de los factores de mejora(2023) Arroyo Pardo, Eduardo; Álvarez Melcón, Ángela Concepción; Calero García, María Luz; Belando Montoro, María Remedios; Delgado Losada, María Luisa; González Matilla, Juan Francisco; Hernández Martín, Marta María; López Parra, Ana María; Aguilera Morales, Encarnación; Díaz Ramiro, Eva María; Fuentes Gómez-Calcerrada, Juan Luis; García Molto, Amelia Isabel Martina; González Martín, María Rosario; Hernández Ibáñez, María Del Carmen; Lopes Gomes, Claudia Filipa; López Matayoshi, César Yoshi; López Sánchez, Ramón; Moreno Pimentel, Antonio Gabriel; Palomo Díez, Sara; Prados Atienza, José María; Rebollada Merino, Agustín Miguel; Redondo Corcobado, Paloma; Rodríguez Bertos, Antonio Manuel; Royo Moreno, Fernando María; Rubio Valdehita, Susana; Tabanera De Lucio, Enrique; Martín Freire, Vanesa; Chinchilla Rodríguez, Blanca; Delgado Ramos Lima, Alice Helena; Porras González, NéstorEl objeto del proyecto es realizar una reflexión conjunta de profesores en diferentes departamentos, con el fin de identificar aquellos ítems, planteados por Docentia-UCM, que han arrojado resultados mejorables. Posteriormente serán contrastados con un panel de docentes calificados como “excelentes” (de los que algunos ya forman parte del presente proyecto), en base al programa, con excelencia en una jornada de reflexión, abierta a todos los profesores de cada departamento implicado, y a los delegados de las asignaturas impartidas por dicho departamento. Se busca la mejora de las evaluaciones de los profesores. - Project number: 428
Item GROSSPath 3D: Principales lesiones macroscópicas de decomiso en matadero en tres dimensiones(2021) Rodríguez Bertos, Antonio Manuel; González Huecas, Marta; Hernández Carrillo, Javier; Martín Andrés, Carlos; Mayoral Alegre, Francisco José; Pérez Pérez, Antonio; Pizarro Díaz, Manuel; Porras González, Néstor; Rebollada Merino, Agustín MiguelEn GROSSPath 3D hemos creado modelos 3D de las lesiones observadas en los órganos decomisados en el matadero, centrado en las principales lesiones de decomiso en el cerdo para generar imágenes 3D que puedan resultar de interés para los alumnos de Grado en Veterinaria. En estos casos hemos incluido la descripción macroscópica de la lesión, el diagnóstico morfológico anatomopatológico y una imagen histológica característica del proceso con la causa etiológica microbiológica tanto en español como en inglés. Con el fin de establecer colaboraciones futuras con los mataderos, que son nuestra principal fuente de lesiones en los animales de abasto, hemos facilitado el acceso a la web a los veterinarios inspectores para que determinen su utilidad, como herramienta formativa para los veterinarios sustitutos o en formación del matadero. Además, conseguir fomentar su interés en contribuir de forma permanente al desarrollo de esta página web GROSSPath 3D mediante el envío de órganos decomisados, especialmente en otras especies como pequeños rumiantes, bovino y equino.
