Gene expression profile suggests that pigs (Sus scrofa) are susceptible to Anaplasma phagocytophilum but control infection
Investigation article published in Parasites and vectors
BACKGROUND: Anaplasma phagocytophilum infects a wide variety of hosts and causes granulocytic anaplasmosis in humans, horses and dogs and tick-borne fever in ruminants. Infection with A. phagocytophilum results in the modification of host gene expression and immune response. The objective of this research was to characterize gene expression in pigs (Sus scrofa) naturally and experimentally infected with A. phagocytophilum trying to identify mechanisms that help to explain low infection prevalence in this species.
RESULTS: For gene expression analysis in naturally infected pigs, microarray hyb…

A Bayesian approach to study the risk variables for tuberculosis occurrence in domestic and wild ungulates in South Central Spain
Investigation article published in BMC Veterinary Research
Bovine tuberculosis (bTB) is a chronic infectious disease mainly caused by Mycobacterium bovis. Although eradication is a priority for the European authorities, bTB remains active or even increasing in many countries, causing significant economic losses. The integral consideration of epidemiological factors is crucial to more cost-effectively allocate control measures. The aim of this study was to identify the nature and extent of the association between TB distribution and a list of potential risk factors regarding cattle, wild ungulates and environmental aspects in Ciudad Real, a Spanish pro…

Risk of African swine fever introduction into the European Union through transport-associated routes: returning trucks and waste from international ships and planes
BMC Veterinary Research publish this investigation article
The uncontrolled presence of African swine fever (ASF) in Russian Federation (RF) poses a serious risk to the whole European Union (EU) pig industry. Although trade of pigs and their products is banned since the official notification in June 2007, the potential introduction of ASF virus (ASFV) may occur by other routes, which are very frequent in ASF, and more difficult to control, such as contaminated waste or infected vehicles. This study was intended to estimate the risk of ASFV introduction into the EU through three types of transport routes: returning trucks, waste from international ship…

Incongruence between the cps type 2 genotype and host-related phenotypes of an Enterococcus faecalis food isolate
Investigation article published in International Journal of Food Microbiology
Enterococcus faecalis is a nosocomial opportunistic pathogen, but is also found in fermented food products where it plays a fundamental role in the fermentation process. Previously, we have described the non-starter E. faecalis cheese isolate QA29b as harboring virulence genes and proven to be virulent in Galleria mellonella virulence model. In this study, we further characterized this food strain concerning traits relevant for the host-pathogen relationship. QA29b was found to belong to sequence type (ST) 72, a common ST among food isolates, and thus we consider it as a good representative of…

Comparative assessment of analytical approaches to quantify the risk for introduction of rare animal diseases: the example of Avian Influenza in Spain
Risk Analysis publish this investigation article
Trade of animals and animal products imposes an uncertain and variable risk for exotic animal diseases introduction into importing countries. Risk analysis provides importing countries with an objective, transparent, and internationally accepted method for assessing that risk. Over the last decades, European Union countries have conducted probabilistic risk assessments quite frequently to quantify the risk for rare animal diseases introduction into their territories. Most probabilistic animal health risk assessments have been typically classified into one-level and multilevel binomial models. …

Study of peripheral blood cell populations involved in the immune response of goats naturally infected with Mycobacterium caprae
Investigation published in Research in Veterinary Science
Tuberculosis in goats caused by Mycobacterium bovis and Mycobacterium caprae has noteworthy sanitary and economic implications. Current diagnostic assays are based on cellular immunity and although they have demonstrated a high sensitivity, some animals remain undetected. In the present study, flow cytometry has been used to determine changes in CD4+, CD8+ and CD25+ T cell populations in peripheral blood from naturally infected goats. Proportion of lymphocytes producing PPD-specific interferon-gamma (IFN-γ) was calculated and an ELISA for detection of PPD-specific IFN-γ was performed…
