Quantitative epidemiology for the characterization of the performance of diagnostic tests used in the frame of the Spanish bovine tuberculosis eradication program

PhD Thesis defense by Alberto Gómez Buendía at the VISAVET Centre of the Complutense University of Madrid

Bovine tuberculosis (bTB), a notifiable zoonotic disease caused by bacteria of the Mycobacterium tuberculosis complex, poses a significant risk to public and animal health. The European Union regulatory framework requires Member States to implement control, surveillance, and eradication programs. Several countries have achieved this objective, but Spain has not yet reached disease eradication despite its efforts. However, many provinces have obtained the officially bTB-free (OTF) status or have very low prevalences, a situation that poses new challenges. These include maintaining the efficienc… Leer más

Epidemiology of resistance to aminoglycosides and macrolides in thermotolerant Campylobacter in livestock in Spain

PhD Thesis defense by Vicente López Chavarrías at the VISAVET Centre of the Complutense University of Madrid

Antimicrobial resistance is a major problem for the treatment of diseases caused by zoonotic bacteria such as thermotolerant Campylobacter (C. coli and C. jejuni). The mechanisms by which antimicrobial resistance spreads over bacterial populations, especially via horizontal gene transfer, can have broad consequences depending on the speed at which resistant phenotypes disseminate through food animal hosts, humans and the environment. Particularly relevant are genetic determinants capable of conferring resistance to three or more antimicrobial classes, making treatments more complicated when mu… Leer más

Estudio histopatológico e inmunohistoquímico de la expresión de integrinas en el carcinoma gástrico canino

Degree Final Project defended by Adrian Arribas Mercado

Gastric carcinoma represents 60–70% of gastric neoplasms in dogs. The malignancy of these neoplasms is based on cellular characteristics such as pleomorphism, anisocytosis, anisokaryosis, atypical mitoses and mitotic index among others; but undoubtedly, migration, infiltration and metastasis of neoplastic cells are the criteria that determine the invasiveness of a tumor. These criteria can be determined by immunohistochemical study of certain transmembrane proteins called integrins. These molecules are composed of two separate subunits, ? (alpha) and ? (beta) subunits, which combine to form … Leer más

Veterinaria forense: estudio de la senescencia celular en perros emaciados procedentes de abuso animal

Alba Revilla Ruiz defended this Degree Final Project

Animal abuse is an increasing concern in society, and veterinary forensic pathologists play a critical role in combating maltreatment by identifying non-accidental injuries in animals. This study aimed to comparatively analyze the macro and microscopic lesions, as well as p53 immunoexpression, in dogs with varying degrees of emaciation (Body Condition 1, 2 and 3) from suspected cases of abuse. Anatomopathological findings were thoroughly examined, and immunohistochemical techniques were applied to key tissues to evaluate nuclear p53 expression as a marker of cellular damage and potential senes… Leer más

Determinación de la circulación del virus Toscana en lagomorfos de la Comunidad de Madrid

Degree Final Project defended by Sofía Gansievich Levit

El virus Toscana (TOSV) es un flebovirus perteneciente a la familia Phenuiviridae, transmitido por flebótomos, principalmente de los géneros P. perniciosus y P. perfilewi. Este virus presenta neurotropismo y puede causar meningitis y meningoencefalitis. Desde su descubrimiento en Italia en 1971, se ha documentado su presencia en diversos países del Mediterráneo, incluyendo España. A través de estudios serológicos y moleculares, se ha demostrado la circulación del virus en humanos y animales domésticos y silvestres, lo que indica una epidemiología compleja y posiblemente infradiagnost… Leer más

Evaluation of ante-mortem diagnostic techniques for tuberculosis in New World camelids

Degree Final Project defended by Sofía Cobos Blázquez

In the last years, the popularity of South American camelids or “New World camelids” (NWC), a term which mainly englobes llamas and alpacas, has increased in Europe. They are used for multiple purposes such as wool production, pasture care or trekking. For this reason, veterinary treatment of this species has been gradually developing, with increasing concern for diseases that affect them and those that can be transmitted to humans. Among them is tuberculosis (TB), caused by mycobacterias of the Mycobacterium tuberculosis complex (MTBC) specially M.bovis, causing respiratory clinical signs… Leer más
