Detection of bluetongue serotype 4 in mouflons (Ovis aries musimon) from Spain
Investigation published in Veterinary Microbiology
Bluetongue serotype 4 (BTV4) has been detected for the first time in tissue samples from 2 mouflons (Ovis aries musimon) from the South of Spain, in a retrospective study. The samples included in this study had been fixed and paraffin-embedded for over a year prior to their analysis using a BTV group-specific and a BTV4-specific RT-PCR test. Lung and lymphatic nodes were found positive in both specimens. The amplified DNA was confirmed to be BTV4 by sequencing the RT-PCR products and comparing them with other sequences from GenBank. The combination of RNA extraction from paraffin-embedded samp…

High spoligotype diversity within a Mycobacterium bovis population: Clues to understanding the demography of the pathogen in Europe
Investigation article published in Veterinary Microbiology
Mycobacterium bovis is the main causative agent of bovine tuberculosis. This zoonotic disease produces important economic losses and must be considered a threat to endangered animal species and public health. This study was performed (1) to assess the degree of diversity of the Spanish M. bovis isolates and its effect on the epidemiology of the infection, and (2) to understand the connection of M. bovis populations within a European context. In this report we resume the DVR-spoligotyping results of 6215 M. bovis isolates collected between 1992 and 2007 from different hosts. The isolates cluste…

El lobo y la OMS
New article published in Tribuna Complutense
Ya despojados de la premura a la que, lamentablemente, la necesidad de la toma de decisiones en un tema tan sensible como es la salud nos conduce, se puedan analizar algunas de las medidas adoptadas con un cierto rigor y, sobre todo, lejanía. No obstante, en los pasados días se ha abierto una nueva polémica sobre la actuación de la Organización Mundial de la Salud (OMS) en este tema. Recientemente han surgido sospechas sobre si la OMS, que en abril declaró la primera pandemia del siglo XXI, alarmó excesivamente a los Gobiernos y, sobre todo, a la población, con la ilegítima intención (no demos…

Resistencia a antibióticos en bacterias humanas y animales
Unidad de Información Científica y Divulgación de la Investigación. OTRI published this online article
La resistencia a los antibióticos es uno de los mayores retos sanitarios de la actualidad. Una dificultad adicional es la que ha estudiado un grupo de investigación de la Universidad Complutense de Madrid, que ha identificado y caracterizado un vehículo de genes de resistencia a antibióticos que ha pasado de bacterias que afectan al cerdo a bacterias que afectan al hombre. No se trata de una alarma sanitaria, se trata de un problema ecológico que requiere una colaboración científica multidisciplinar en la que España debe ser uno de los principales protagonistas…

Presence of Rickettsia raoultii in Dermacentor Ticks from Wildlife in Central Spain
Poster presented in 8th ASM Biodefense and Emerging Diseases Research Meeting
The genus Rickettsia includes a large number of bacteria considered important emerging tick-borne human pathogens. The genus is divided into three groups: the typhus group (TG), the scrub typhus group and the spotted fever group (SFG). SFG rickettsiae include several pathogenic and nonpathogenic species such as R. conori, R. massilae and R. raoultii. R. raoultii was first isolated in Russia in 1999 and defined as a new species in 2008. Since then this agent has been detected in different European scenarios implicated in human and animal disease and mainly associated with Dermacentor ticks.

EFSA and ECDC issue their anual report on zoonoses and food-borne outbreaks in the EU
New post published in Blog Madri+d de Seguridad Alimentaria y Alimentación
The European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC) have published their Annual Report on Zoonoses and Food-borne outbreaks for 2008, which gives an overview of zoonotic infections shared in nature by humans and animals and disease outbreaks caused by consuming contaminated food. The report shows that the number of human cases of the three most reported zoonotic infections was lower in 2008 than in 2007…

Experimental infection with Mycobacterium caprae in goats and evaluation of immunological status in tuberculosis and paratuberculosis co-infected animals
Investigation published in Veterinary Immunology and Immunopathology
Tuberculosis in goats (caused by Mycobacterium caprae and M. bovis) has become a significant concern in recent years because of its high prevalence in certain caprine herds in Spain and other European countries, and also due to the potential transmission to other animals and human beings. In the present study, a transthoracic model of tuberculosis infection was performed on goats. Animals were selected based on the serological response used to detect paratuberculosis in goats (negative and positive results). The kinetics of the immune response was evaluated using the interferon-gamma (IFN-gamm…

Avian mycobacteriosis in free-living raptors in Majorca Island, Spain
Investigation published in Avian Pathology: journal of the W.V.P.A
Avian mycobacteriosis is a chronic, infectious disease caused by different species of mycobacteria, usually belonging to the Mycobacterium avium complex. From 2004 to 2007, 589 raptors brought dead or sick to a wildlife rehabilitation centre in Majorca (Balearic Islands, Spain) were necropsied. The birds belonged to 12 different species, chiefly common kestrel (Falco tinnunculus) (n=297), scops owl (Otus scops) (n=109), barn owl (Tyto alba) (n=75), long-eared owl (Asio otus) (n=58), peregrine falcon (Falco peregrinus) (n=27), and booted eagle (Hieraaetus pennatus) (n=13).

Resistance mechanisms and farm-level distribution of fecal Escherichia coli isolates resistant to extended-spectrum cephalosporins in pigs in Spain
Research in Veterinary Science publish this investigation article
INTRODUCTION: Fecal Escherichia coli isolates showing a phenotype of reduced susceptibility or resistance to extended-spectrum cephalosporins are common among pigs in Spain. The aim of this study was to describe the main beta-lactam resistance mechanisms carried by these strains and their distribution at farm-level. MATERIALS AND METHODS: Twenty-nine E. coli isolates showing reduced susceptibility or resistance to extended-spectrum cephalosporins were collected from a sampling frame of 80 pig farms distributed over 13 Spanish provinces. The survey was carried out at the slaughterhouse level in…
