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 the 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…

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) in relation to biofilms and its impact on Food Safety
Revista del Comité Científico de la AESAN publish this article
In the last two decades, it has been noted that bacteria are found not only free in the environment, as unicellular organisms, but on many occasions may be found forming part of microbial communities with an organization system more typical of colonial organisms, i.e. adhering to surfaces and embedded in ex¬tracellular matrices that they synthesize for themselves.These biological structures are known as biofilms.
The formation of biofilms is an adaptive strategy of micro-organisms that allows an increase in their possibilities of surviving in the environment and implies a new concept of “bac…

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the applicable microbiological criteria for pathogenic species of the genus Vibrio in imported fishery products, as additional control measures at border inspection posts
New article published in Revista del Comité Científico de la AESAN
The present report aims to determine the currency of the present system for health-related control of frozen fishery products at border inspection posts, with regard to the pathogenic species of the genus Vibrio and more specifically, V. cholerae, V. parahaemolyticus and V. vulnificus.
In view of the current scientific knowledge and risk assessment, the of microbiological criteria at border inspection posts is justified as an additional and complementary control measure. With regard to V. cholerae specifically, it is recommended to apply a zero-tolerance criterion without distinguishing betw…

Experimental infection of European red deer (Cervus elaphus) with bluetongue virus serotypes 1 and 8
Veterinary Microbiology publish this investigation article
Bluetongue (BT) is a climate change-related emerging infectious disease in Europe. Outbreaks of serotypes 1, 2, 4, 6, 8, 9, 11, and 16 are challenging Central and Western Europe since 1998. Measures to control or eradicate bluetongue virus (BTV) from Europe have been implemented, including movement restrictions and vaccination of domestic BTV-susceptible ruminants. However, these measures are difficult to apply in wild free-ranging hosts of the virus, like red deer (Cervus elaphus), which could play a role in the still unclear epidemiology of BT in Europe. We show for the first time that BTV R…

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…

Assessment of several detection and cultive protocols: Detection of Campylobacter from different matrices
María Ugarte Ruiz defended this presentation at the Faculty of Veterinary Medicine of the Complutense University of Madrid in order to obtain the Master of Research
Campylobacter spp., and especially C. jejuni and C. coli, are Gram-negative pathogens of primary importance, as campylobacteriosis remains to be the most frequently reported zoonotic disease in humans in the European Union. This fact highlights the control of Campylobacter throughout the food chain as one of the main objectives to be achieved by the Food Safety Agencies at European level.
Campylobacter is a, microaerophilic bacillus, highly motile, of slow growth rate and with an optimal culture growth temperature of about 37-42ºC. These characteristics hinder its isolation, so it is consid…

La esquina europea: ser un científico en Europa, 27 experiencias
Oral communication in La noche de los investigadores
El investigador forma parte de la sociedad y contribuye a su desarrollo, mejora nuestra calidad de vida y hace que nuestro día a día sea más sencillo y ameno. Además es un ser humano como cualquiera de nosotros, con sus inquietudes, dudas y hobbies.
El objetivo de esta actividad es acercar la figura del investigador a los asistentes, propiciando un encuentro informal entre el público y los investigadores. Fomentar en los jóvenes la elección de una carrera científico-técnica así como las vocaciones científicas son también objetivos que se persiguen con esta actividad.
Teniendo como fondo la p…

Bluetongue vaccination in Europe
Expert Review of Vaccines publish this investigation article
Bluetongue virus (BTV) is the cause of blue¬tongue (BT), an insect-transmitted disease of domestic and wild ruminants. BTV infection occurs throughout many of the temperate and tropical regions of the world, coincident with the distribution of specific species of Culicoides biting midges that act as biological vectors of the virus. BT typi¬cally occurs when susceptible animal spe¬cies are introduced into areas where virulent strains of BTV circulate, or when virulent strains of BTV extend their range into previ¬ously unexposed populations of ruminants. Following the recent northern European ep…

Characterization of Some Bacterial Strains Isolated from Animal Clinical Materials and Identified as Corynebacterium xerosis by Molecular Biological Techniques
Investigation published in Journal of Clinical Microbiology
Eighteen C. xerosis strains isolated from different animal clinical specimens were subjected to phenotypic and molecular genetic studies. On the basis of the results of the biochemical characterization, the strains were tentatively identified as C. xerosis. Phylogenetic analysis based on comparative analysis of the sequences of 16S rRNA and rpoB genes revealed that the 18 strains were highly related to C. xerosis, C. amycolatum, C. freneyi and C. hansenii. There was a good concordance between 16S rRNA and partial rpoB gene sequencing results, although partial rpoB gene sequencing allowed a bet…

Eurasian wild boar response to skin-testing with mycobacterial and non-mycobacterial antigens
Preventive Veterinary Medicine publish this investigation article
Eurasian wild boar (Sus scrofa) are able to maintain bovine tuberculosis (bTB) in the wild and are most probably able to transmit the disease to other species, thus acting as a true wildlife reservoir. Translocation of wild boar is a common practice in European countries. Therefore, identifying effective tools for bTB diagnosis in living wild boar is crucial for the implementation of control measures. We describe for the first time the sex and origin related differences in the skin-test response to mycobacterial antigens (bPPD and aPPD) and to a non-mycobacterial antigen (PHA, a plant derived …
