    Les jornades d'innovació docent a la Facultat de Veterinària tenen per objectiu l'intercanvi d'experiències docents entre el professorat de la Facultat com a punt de partida per reflexionar sobre l'estat actual de la docència i estimular la inclusió de noves activitats d'innovació als estudis de grau. Aquestes jornades estan organitzades pel Grup d'Innovació Docent de la Facultat de Veterinària amb el suport de la Unitat de Formació i Innovació Docent (OQD) de la Universitat Autònoma de Barcelona

    Study of poultry livers as a source of Campylobacter

    TFMOne HealthCampylobacter is the most common bacterial cause of human gastroenteritis in the world. The largest contributor of human Campylobacter infection in developed countries is considered poultry and poultry products. The current European legislation regulates levels of Campylobacter only on the neck skin from broiler carcases at a slaughterhouse. However, foodborne campylobacteriosis has also been linked to undercooked chicken liver

    Cyclodextrins as capture agents of lipophilic marine toxins

    TFMOne HealthSeafood contamination with marine toxins due to harmful algal blooms (HABs) is a global public health issue on the rise. Most countries have monitoring programs for the detection of toxins in shellfish of toxic phytoplankton in seawater to prevent consumer intoxications. The use of solid phase adsorbent and toxin tracking (SPATT) technology as toxin detection straight from the aquatic environment could complement the labourintensive traditional monitoring methods. In this work, several types of cyclodextrins (cyclic oligomers with a conical structure and an internal cavity) have been evaluated as novel materials for SPATT. Cyclodextrins were tested at Masnou harbour (Catalonia, NW Mediterranean) during a Dinophysis sp. bloom. The cyclodextrins and the commercial Diaion (HP-20) were deployed twice for a 1-week period at five different locations of Masnou harbour. At the time of the experiment, Dinophysis sp. reached abundances as high as 91 341 cells /L. Successful accumulations of the lipophilic marine toxins okadaic acid (OA) and pectenotoxin-2 (PTX2) were quantified by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Higher levels of PTX2 were found in all cyclodextrins whereas OA and PTX2 contents were similar in the commercial resin. Accumulation of OA was higher in the commercial resin than in cyclodextrins, but these last proved best for PTX2 adsorption. A clear correlation between cell abundance and toxin accumulation was observed
