Clonal diversity of Staphylococcus aureus originating from the small ruminants goats and sheep

Investigation published in Veterinary Microbiology

Staphylococcus aureus is an important pathogen in humans and many animal species. The prevalence of different clonal types in animal species remains largely unknown. We analyzed 267 S. aureus from intramammary infections in goats (47) and sheep (220) by spa typing, multi-locus sequence typing (MLST) and antimicrobial susceptibility. The most frequent spa types in goats were t337 (N=9), t759 (N=6) and t1534 (N=5). Sheep isolates mainly belonged to spa types t1534 (N=72), t2678 (N=29) and t3576 (N=20). Eighteen novel spa-types were observed; two from goat strains, 13 from sheep and three in both… Read more

Factors driving the abundance of ixodes ricinus ticks and the prevalence of zoonotic I. ricinus-borne pathogens in natural foci

Investigation article published in Applied and Environmental Microbiology

Environmental factors may drive tick ecology and therefore tick-borne pathogen (TBP) epidemiology, which determines the risk to animals and humans of becoming infected by TBPs. For this reason, the aim of this study was to analyze the influence of environmental factors on the abundance of immature-stage Ixodes ricinus ticks and on the prevalence of two zoonotic I. ricinus-borne pathogens in natural foci of endemicity. I. ricinus abundance was measured at nine sites in the northern Iberian Peninsula by dragging the vegetation with a cotton flannelette, and ungulate abundance was measured by mea… Read more

Characterization of the immune response induced by a commercially available inactivated Bluetongue virus serotype 1 vaccine in sheep

Scientific World Journal publish this investigation article

The protective immune response generated by a commercial monovalent inactivated vaccine against bluetongue virus serotype 1 (BTV1) was studied. Five sheep were vaccinated, boost-vaccinated, and then challenged against BTV1 ALG/2006. RT-PCR did not detect viremia at any time during the experiment. Except a temperature increase observed after the initial and boost vaccinations, no clinical signs or lesions were observed. A specific and protective antibody response checked by ELISA was induced after vaccination and boost vaccination. This specific antibody response was associated with a significa… Read more

Detection of Methicillin Resistant Staphylococcus aureus in Iberian pigs

Investigation published in Letters in Applied Microbiology

Aims: Iberian pigs are bred in Spain for production of high-value dry-cured products, whose export volumes are increasing. Animals are typically reared outdoors, though indoor farming is becoming popular. We compared carriage of Methicillin Resistance Staphylococcus aureus (MRSA) in Iberian pigs, raised indoors and outdoors, with intensively farmed Standard White pigs. Methods and Results:  From June 2007 to February 2008, 106 skin swabs were taken from Iberian pigs and 157 samples from Standard White pigs at slaughterhouses in Spain. We found that Iberian pigs carried MRSA, though with … Read more

Quantitative Risk Assessment for the Introduction of African Swine Fever Virus into the European Union by Legal Import of Live Pigs

Transboundary and Emerging Diseases publish this investigation article

The recent incursion and spread of African swine fever virus (ASFV) in the Russian Federation and Caucasus region, close to European Union (EU) borders, have increased the concerns regarding the probability of ASFV introduction into the EU. There are many potential routes of ASFV entry into EU, but here we specifically aimed to assess the probability of ASFV introduction by legal trade of pigs, which historically has been one of the most important ways of exotic diseases introduction into the EU. A stochastic model was used to estimate the monthly probability of ASFV introduction for each coun… Read more

Progress in molecular typing of Mycobacterium avium subspecies paratuberculosis

Investigation published in Research in Veterinary Science

Mycobacterium avium subspecies paratuberculosis (M. a. paratuberculosis) is responsible for paratuberculosis or Johne`s disease, a chronic inflammation of the gastrointestinal tract in different animal species. Some studies have also established a link between this microorganism and Crohn`s disease in humans. Although, M. a. paratuberculosis is a difficult microorganism to cultivate in the laboratory (occasionally is non-cultivable), a proper molecular characterization of M. a. paratuberculosis is necessary to better understand the epidemiology of the disease, and design strategies to eradicat… Read more
