Propuestas de enseñanza semipresencial basadas en el trabajo colaborativo

La pandemia ocasionada por la COVID-19 ha obligado al docente a revisar las metodologías utilizadas con los estudiantes para permitir la mejora del aprendizaje. El trabajo colaborativo organiza a los estudiantes en grupos para estudiar de forma conjunta y coordinada, permitiendo profundizar en su propio aprendizaje y en el de los otros miembros del grupo al ayudarse mutuamente. Esta metodología de trabajo se aplica desde hace unos años en nuestras asignaturas, pero ha tenido que ser reestructurado ante la imposibilidad de acudir a los centros. La nueva estrategia de aprendizaje utilizada queda detallada en este trabajo donde, tras obtener unos óptimos resultados en la evaluación final, y analizar los resultados a través de una encuesta de satisfacción totalmente anónima de los estudiantes del Grado de Veterinaria, eminentemente práctico, se detectan algunas ventajas y algunos inconvenientes. Las metodologías utilizadas, además, permiten acceder desde fuera del aula a los estudiantes con discapacidad auditiva, mediante el empleo de videos donde es posible explicar sin mascarilla. Todo ello permitirá impartir docencia en materias basadas en la presencialidad, en las que las clases magistrales han ocupado tradicionalmente el total de las horas teóricas

One Health Approach: Invasive California Kingsnake (Lampropeltis californiae) as an Important Source of Antimicrobial Drug-Resistant Salmonella Clones on Gran Canaria Island

The increase in the reptile population has led to a rise in the number of zoonotic infections due to close contact with reptiles, with reptile-associated salmonellosis being particularly relevant. California kingsnake invasion not only threatens the endemic reptile population of the island of Gran Canaria (Spain) but also poses serious public health problems by spreading zoonotic pathogens and their antimicrobial resistance (AMR) to the environment. Thus, the aim of this study was to assess the occurrence, genetic diversity, and AMR among Salmonella spp. strains isolated from California kingsnakes in Gran Canaria Island (Spain). Of 73 invasive individuals captured, 20.5% carried Salmonella spp., belonging to different subspecies and serovars, with subsp. salamae as the most abundant. Pulsed-field electrophoresis showed high genetic diversity among subsp. salamae isolates, and among these, 73.3% showed resistance to at least one of the antimicrobials tested. In conclusion, the present study revealed the importance of wild invasive California kingsnakes as reservoirs of drug-resistant Salmonella spp. that could pose a direct threat to livestock and humans. Identification of drug-resistant Salmonella strains in wildlife provides valuable information on potential routes of transmission that involve risks to public and animal health.This study was supported by the project “POSTLIFE+ Lampropeltis para el control de la culebra real de California en Gran Canaria (LIFE10/NAT/ES/656)” financed by the Government of Canary Islands, Cabildo of Gran Canaria and Universidad Cardenal Herrera-CEU (IDOC 19/15, and INDI 20-21, INDI 22-34).info:eu-repo/semantics/publishedVersio

One Health Approach : Invasive California Kingsnake (Lampropeltis californiae) as an Important Source of Antimicrobial Drug-Resistant Salmonella Clones on Gran Canaria Island

The aim of this study was to investigate the invasive species Lampropeltis californiae (California kingsnake) as a reservoir of Salmonella and its ability to spread different clones of the bacterium with zoonotic potential into the environment, as well as study its antimicrobial resistance patterns in Gran Canaria (Spain). The main results showed that a high diversity of Salmonella subsp. salamae strains circulate in Gran Canaria with a high prevalence of resistance shown for antimicrobials of public health importance, as summarised in the European Decision 2013/652/EU. The increase in the reptile population has led to a rise in the number of zoonotic infections due to close contact with reptiles, with reptile-associated salmonellosis being particularly relevant. California kingsnake invasion not only threatens the endemic reptile population of the island of Gran Canaria (Spain) but also poses serious public health problems by spreading zoonotic pathogens and their antimicrobial resistance (AMR) to the environment.
