Tuberculosis epidemiology in islands: insularity, hosts and trade
Artículo de investigación publicado en PLoS ONE
Because of their relative simplicity and the barriers to gene flow, islands are ideal systems to study the distribution of biodiversity. However, the knowledge that can be extracted from this peculiar ecosystem regarding epidemiology of economically relevant diseases has not been widely addressed. We used information available in the scientific literature for 10 old world islands or archipelagos and original data on Sicily to gain new insights into the epidemiology of the Mycobacterium tuberculosis complex (MTC). We explored three nonexclusive working hypotheses on the processes modulating bov…

African swine fever (ASF): Five years around Europe
Investigación publicada en Veterinary Microbiology
Since African swine fever (ASF) was re-introduced into Eastern Europe in April 2007, the disease has spread through five countries, drastically changing the European ASF situation. This re-introduction has significant implications for the affected countries, and it puts the European Union (EU) at serious risk of ASF introduction. Numerous factors are complicating the control of ASF in the Russian Federation and neighboring areas, particularly the absence of a coordinated control program, the abundance of backyard pig units with low or no biosecurity and the traditional use of swill feeding. Al…

Identification of suitable areas for the occurrence of Rift Valley fever outbreaks in Spain using a multiple criteria decision framework
Investigación publicada en Veterinary Microbiology
Rift Valley fever (RVF) is a mosquito-borne viral disease that may produce a considerable impact on the economy in affected countries. In the last decades, the geographic distribution of RVF virus has increased including most of the countries in Africa, Arabia Saudi and Yemen. This situation has raised the concerns regarding its potential introduction in the European Union (EU) countries where the high number of susceptible species and competent vectors may contribute to the spread of the disease and challenge its rapid control. Thus, the identification of the areas and time periods with highe…

Evaluation of the risk of classical swine fever (CSF) spread from backyard pigs to other domestic pigs by using the spatial stochastic disease spread model Be-FAST: The example of Bulgaria
Artículo de investigación publicado en Veterinary Microbiology
The study presented here is one of the very first aimed at exploring the potential spread of classical swine fever (CSF) from backyard pigs to other domestic pigs. Specifically, we used a spatial stochastic spread model, called Be-FAST, to evaluate the potential spread of CSF virus (CSFV) in Bulgaria, which holds a large number of backyards (96% of the total number of pig farms) and is one of the very few countries for which backyard pigs and farm counts are available. The model revealed that, despite backyard pigs being very likely to become infected, infections from backyard pigs to other do…

Control of bluetongue in Europe
Veterinary Microbiology publica este artículo de investigación
Since 1998, bluetongue virus (BTV) serotypes 1, 2, 4, 6, 8, 9, 11 and 16 have spread throughout Europe. In 2006, BTV serotype 8 (BTV-8) emerged unexpectedly in northern Europe throughout a region including Belgium, France, Germany, Luxembourg and the Netherlands. In the following year, it spread rapidly throughout the rest of Europe. In 2008, two more BTV serotypes were detected in northern Europe: BTV-6 in the Netherlands and Germany and BTV-11 in Belgium. The European incursion of BTV has caused considerable economic losses, comprising not only direct losses from mortality and reduced produc…

Simultaneous diagnosis of Cetacean morbillivirus infection in dolphins stranded in the Spanish Mediterranean sea in 2011 using a novel Universal Probe Library (UPL) RT-PCR assay
Investigación publicada en Veterinary Microbiology
A highly sensitive and specific real-time (rt) RT-PCR assay has been developed for rapid, simultaneous detection of three strains of cetacean morbillivirus (CeMV). In this assay, two PCR primers and a hydrolysis probe from a commercially available Universal Probe Library (UPL) are used to amplify a highly conserved region within the fusion protein gene. RT-PCR is carried out on the same sample using two primer sets in parallel: one set detects the more virulent strains, dolphin morbillivirus (DMV) and porpoise morbillivirus (PMV), and the other set detects the least virulent and least common s…

Potential use of oral fluid samples for serological diagnosis of African swine fever
Investigación publicada en Veterinary Microbiology
African swine fever (ASF) is a complex, highly lethal, notifiable disease of swine. ASF is wide-spread in sub-Saharan Africa and East European countries and there is presently a great risk of spread to neighboring countries. Since there is no vaccine for ASF virus (ASFV), control is based on rapid and early detection of the disease via surveillance. This approach requires collecting blood samples from large number of animals. Laborious and expensive of itself, this process also presents an additional risk because ASFV is present at high concentrations in the blood. The objective of this study …

Identification of Hotspots in the European Union for the Introduction of Four Zoonotic Arboviroses by Live Animal Trade
Investigación publicada en PLoS ONE
Live animal trade is considered a major mode of introduction of viruses from enzootic foci into disease-free areas. Due to societal and behavioural changes, some wild animal species may nowadays be considered as pet species. The species diversity of animals involved in international trade is thus increasing. This could benefit pathogens that have a broad host range such as arboviruses. The objective of this study was to analyze the risk posed by live animal imports for the introduction, in the European Union (EU), of four arboviruses that affect human and horses: Eastern and Western equine enc…

Detection and assessment of electrocution in endangered raptors by infrared thermography
BMC Veterinary Research publica este artículo de investigación
BACKGROUND: Most European birds of prey find themselves in a poor state of conservation, with electrocution as one of the most frequent causes of unnatural death. Since early detection of electrocution is difficult, treatment is usually implemented late, which reduces its effectiveness. By considering that electrocution reduces tissue temperature, it may be detectable by thermography, which would allow a more rapid identification. Three individuals from three endangered raptor species [Spanish imperial eagle (Aquila adalberti), Lammergeier (Gypaetus barbatus) and Osprey (Pandion haliaetus)] we…

Estudio de la capacidad adyuvante del plásmido que contiene la secuencia CpG específica de cerdos en dos vacunas porcinas
Guo Xiaoyu defendió su tesis doctoral en la Facultad de Veterinaria de la Universidad Complutense de Madrid
La secuencia citosina-fosfato-guanosina (CpG) fue descrita como un tipo de inmunoestimulante de la respuesta inmune tanto humoral como celular. La secuencia CpG está flanqueada por dos purinas en 5’ y dos pirimidinas en el extremo 3’ (CpG—ODN). Desde su descubrimiento en 1995, varios estudios han demostrado que ODN, que contiene la secuencia no metilada de CpG (señalada como CpG ODN), puede activar mecanismos de defensa inmune, y estimular la respuesta inmune tanto innata como adquirida…

Optimizing the sampling effort to evaluate body condition in ungulates: A case study on red deer
Ecological Indicators publica este artículo de investigación
Body condition is a useful measure of the nutritional status and performance in ungulates. The most widely used indicators of body condition are based on fat reserves, mainly those surrounding the kidneys. To estimate the body condition in large herbivores, researchers often collect and pool the data from both kidneys and their perirenal fat in order to compensate for potential differences between the body condition indicators obtained from the left and right kidneys. Since these differences do not seem to be properly established in wildlife, we checked for the potential differences between th…

Garvicin A, a novel class IId bacteriocin from Lactococcus garvieae that inhibits septum formation in L. garvieae strains
Applied and Environmental Microbiology publica este artículo de investigación
Lactococcus garvieae 21881, isolated from a human clinical case, produces a novel class IId bacteriocin, garvicin A (GarA), which is specifically active against other L. garvieae strains, including fish and bovine pathogenic isolates. Purification from active supernatants, sequence analyses, and plasmid-curing experiments identified pGL5, one of the five plasmids found in L. garvieae 21881 (Aguado-Urda M, Gibello A, Blanco MM, López-Campos GH, Cutuli MT, Fernández-Garayzábal JF. 2012.

Association of the novel aminoglycoside resistance determinant RmtF with NDM carbapenemase in Enterobacteriaceae isolated in India and the UK
Investigación publicada en The Journal of Antimicrobial Chemotherapy
OBJECTIVES: 16S rRNA methyltransferases are an emerging mechanism conferring high-level resistance to clinically relevant aminoglycosides and have been associated with important mechanisms such as NDM-1. We sought genes encoding these enzymes in isolates highly resistant (MIC >200 mg/L) to gentamicin and amikacin from an Indian hospital and we additionally screened for the novel RmtF enzyme in 132 UK isolates containing NDM. METHODS: All highly aminoglycoside-resistant isolates were screened for armA and rmtA-E by PCR, with cloning experiments performed for isolates negative for these genes. M…

SatR is a repressor of fluoroquinolone efflux pump SatAB
Artículo de investigación publicado en Antimicrobial Agents and Chemotherapy
Streptococcus suis is an emerging zoonotic agent responsible for high-mortality outbreaks among the human population in China. In this species, the ABC transporter SatAB mediates fluoroquinolone resistance when overexpressed. Here we describe and characterize satR, an ORF encoding a MarR-superfamily regulator that acts as a repressor of satAB. satR is cotranscribed with satAB and its interruption entails the overexpression of the pump, leading to a clinically-relevant increase in resistance to fluoroquinolones…

Tuberculosis caprina
Artículo de divulgación publicado en Tierras. Caprino
Mycobacterium bovis es el principal agente etiológico de la tuberculosis bovina y M.caprae infecta más frecuentemente al ganado caprino, aunque ambas micobacterias pueden infectar indistintamente a bovinos y caprinos y a otras especies de mamíferos domésticos y de vida libre. De hecho, y como ha descrito la Task Force para la tuberculosis bovina (bovine tuberculosis subgroup of the Task Force, 2006), podemos definir la tuberculosis caprina como la enfermedad producida en esta especie animal por cualquiera de las especies bacterianas incluidas en el complejo Mycobacterium tuberculosis(MTBC) y n…
