Fluoroquinolone resistance in Streptococcus suis

José Antonio Escudero García-Calderón defended the PhD Thesis at the Faculty of Veterinary Medicine of de Complutense University of Madrid

Streptococcus suis is a worldwide-distributed zoonotic agent affecting pig and man. In industrialized countries it is mainly regarded as an important economic burden to the pig industry that only sporadically causes infections in humans. Nevertheless, in several developing countries in South East Asia, S. suis is one of the main causes of meningitis in humans. Also, S. suis has been reported as the causative agent of large, high-mortality outbreaks among the Chinese population, during the summers of 1998, 1999 and 2005. Mortality was high as a result of the onset of a Toxic Shock Syndrome. Alt… Leer más

Evolution of integrons in Escherichia coli from swine and poultry

PhD Thesis defense by Mauricio Alejandro Marchant Mella at the Faculty of Veterinary Medicine of de Complutense University of Madrid

La resistencia a los antimicrobianos es uno de los problemas de salud pública que mayor preocupación ha suscitado desde finales de los años noventa, debido a la constatación de la existencia de bacterias patógenas frente a las que ninguno de los antimicrobianos conocidos es eficaz. La diseminación de los genes de resistencia entre las bacterias está mediada por diferentes elementos genéticos, entre los cuales, los integrones han sido descritos como uno de los principales vehículos implicados. El objetivo de este estudio ha sido evaluar el papel de los integrones en la diseminación de genes de … Leer más

Tuberculosis in goats: study of immune response and contributions to diagnosis

Javier Bezos Garrido defended the PhD Thesis at the Faculty of Veterinary Medicine of de Complutense University of Madrid

The main objectives of this thesis are the study of the cellular mediated immune response against caprine tuberculosis and the assessment, in terms of sensitivity and specificity, of the tuberculosis diagnostic tests used for the diagnosis of tuberculosis in goats, in particular the single and comparative intradermal test (SIT and SCIT tests respectively) and the IFN-y assay. Regarding the diagnostic tests, sensitivity and specificity in different epidemiological situations, the effect of different technical factors on the results of the IFN-y assay and the diagnostic interference caused by C.… Leer más

Modelo de difusión de la Influenza Aviar Altamente Patógena

PhD Thesis defense by Irene Iglesias Martín at the Faculty of Veterinary Medicine of de Complutense University of Madrid

The aim of this thesis is to identify which areas present a higher risk of spread of Highly Pathogenic Avian Influenza (HPAI) in Spain and to evaluate the consequences that this diffusion would involve, to contribute to the improvement surveillance and control plans against the disease, both wild and domesticated birds. To this aim, it has been developed a diffusion model of HPAI highly adapted to the structural characteristics of our poultry sector, which includes two different stages, the industrial poultry farming of chickens, and backyard poultry combined with no-chicken poultry farm wich … Leer más

Development of epidemiological models to analyse the risk of entry of highly pathogenic avian influenza virus and Newcastle disease virus into Spain

PhD Thesis defense by Fernando Sánchez-Vizcaíno Buendía at the Faculty of Veterinary Medicine of de Complutense University of Madrid

The Spanish poultry sector is considered the third most important of the European Union (EU). This sector results in an estimated income of 2.73 billion of Euros to the country’s economy. Therefore, it is a necessity to keep it free of diseases that may weaken it. Highly pathogenic avian influenza (HPAI) and Newcastle disease (ND) are considered the two most devastating infectious diseases of poultry that a country may suffer. Spain reported an outbreak of HPAI and other of ND in poultry farms in 2009. The HPAI outbreak occurred in a laying hens flock of Almoguera (Guadalajara) and resulted in… Leer más

Bovine tuberculosis: molecular epidemiology and implications in Public and Animal Health

PhD Thesis defense by Beatriz Romero Martínez at the Faculty of Veterinary Medicine of de Complutense University of Madrid

Mycobacterium tuberculosis complex (MTBC) is the cluster of pathogens which posses the higher health concern within the genus Mycobacterium. MTBC comprises seven species, being Mycobacterium tuberculosis the most relevant pathogen for Public Health. Regarding Animal Health, Mycobacterium bovis is the main pathogen that causes tuberculosis in cattle although it has a wide-host range such as wildlife and human beings. Mycobacterium caprae, on the other hand, is the main agent of tuberculosis in goats. The eradication of bovine tuberculosis is the key objective of all programs against this diseas… Leer más

Family Flavobacteriaceae in rainbow trout (Oncorhynchus mykiss) and its involvement in RTFS

Presentation by Leydis Zamora Morales to obtain the Master of Research. Faculty of Veterinary Medicine, Complutense University of Madrid

Flavobacterium psychrophilum es el agente etiológico del síndrome del alevín de la trucha arcoíris (rainbow trout fry síndrome, RTFS), enfermedad septicémica, de curso generalmente agudo, que provoca brotes severos en salmónidos criados en piscifactorías a nivel mundial, con importantes pérdidas económicas. Hasta el momento F. psychrophilum se considera el único agente responsable de RTFS. Sin embargo durante los dos últimos años, estudiamos en nuestro laboratorio 228 alevines con características clínicas y epidemiológicas compatibles con RTFS, pero en los que de manera sistemática no se aisló… Leer más
