Veterinary Immunology and Immunopathology

Isolation and immunophenotyping by flow cytometry of canine peripheral blood and intraepithelial and lamina propria duodenal T lymphocytes

Investigation published in Veterinary Immunology and Immunopathology


The gut associated lymphoid tissue (GALT) effector sites play a crucial role on the pathogenesis of many immune-mediated gastrointestinal diseases. The lymphocytes at these effector sites are principally T cells which present important morphological, phenotypical and functional differences. Flow cytometry (FC) is one of the most commonly used techniques to characterize intestinal lymphocytes in human and animal models. Published studies with a focus on dogs for intraepithelial lymphocytes (IEL) immunophenotyping exist in very limited numbers. Moreover, no lamina propria lymphocytes (LPL) isola… Read more

Genomic evolution of antimicrobial resistance in Escherichia coli

Scientific reports publish this investigation article


The emergence of antimicrobial resistance (AMR) is one of the biggest health threats globally. In addition, the use of antimicrobial drugs in humans and livestock is considered an important driver of antimicrobial resistance. The commensal microbiota, and especially the intestinal microbiota, has been shown to have an important role in the emergence of AMR. Mobile genetic elements (MGEs) also play a central role in facilitating the acquisition and spread of AMR genes. We isolated Escherichia coli (n = 627) from fecal samples in respectively 25 poultry, 28 swine, and 15 veal calf herds from 6 E… Read more

Estudio anatomopatológico y de PCR de la infección por el virus de la mixomatosis y sus variantes en liebre y conejo

Raul Manjavacas Pintado defended this Degree Final Project


Myxomatosis is a characteristic viral disease of rabbits caused by classical Myxoma virus (MYXV), a leporipoxvirus introduced in Europe in the 1950s classically affecting European rabbits (Oryctolagus cuniculus) and causing high lethality. However, in 2018 Iberian hares (Lepus granatensis) from Spain exhibited symptoms compatible with myxomatosis. In the wake of this outbreak, a new recombinant strain of Myxoma virus (MYXV-Tol) was identified. In order to study the distribution of these two variants and their involvement in pathology, 14 animals (8 rabbits and 6 hares) from Madrid and Castilla… Read more

First Detection of SARS-CoV-2 B.1.1.7 Variant of Concern in an Asymptomatic Dog in Spain

Viruses-Basel publish this investigation article


Natural SARS-CoV-2 infection in pets has been widely documented during the last year. Although the majority of reports suggested that dogs’ susceptibility to the infection is low, little is known about viral pathogenicity and transmissibility in the case of variants of concern, such as B.1.1.7 in this species. Here, as part of a large-scale study on SARS-CoV-2 prevalence in pets in Spain, we have detected the B.1.1.7 variant of concern (VOC) in a dog whose owners were infected with SARS-CoV-2. The animal did not present any symptoms, but viral loads were high in the nasal and rectal swabs. In … Read more

Strategies for the prevention and control of Theileria equi and Babesia caballi in the equine population of Spain

PhD Thesis defense by Eliazar Camino Gutiérrez at the VISAVET Centre of the Complutense University of Madrid


Equine piroplasmosis (EP) is a parasitic disease of equids (horses, donkeys, mules and zebras) caused by two intraerythrocytic protozoan parasites within the phylum Apicomplexa: Theileria equi (previously named Babesia equi) and Babesia caballi. These parasites are mainly trasmitted by ixodid tick species belonging to several genera such as Dermacentor, Hyalomma and Rhipicephalus; however, transmission may also occur vertically in utero and iatrogenically. This disease has a hyperacute, acute, subacute or chronic form; affected animals often show variable and nonspecific clinical signs such as… Read more

Ecological Applications

Environment, vector, or host? Using machine learning to untangle the mechanisms driving arbovirus outbreaks

Ecological Applications publish this investigation article


Climatic, landscape and host features are critical components in shaping outbreaks of vector-borne diseases. However, the relationship between the outbreaks of vector-borne pathogens and their environmental drivers is typically complicated, nonlinear and may vary by taxonomic units below the species level (e.g., strain or serotype). Here, we aim to untangle how these complex forces shape the risk of outbreaks of Bluetongue virus (BTV); a vector-borne pathogen that is continuously emerging and re-emerging across Europe, with severe economic implications. We tested if the ecological predictors o… Read more

Detection of Hepatitis E Virus in Hyalomma lusitanicum Ticks Feeding on Wild Boars

Investigation article published in Frontiers in Microbiology


The role of ticks in the maintenance and spread of emerging viral zoonotic pathogens, whose main hosts are wildlife species, is well known (Ruiz-Fons et al., 2008; Baneth, 2014; Madison-Antenucci et al., 2020). Of special concern are wild ungulates (deer and wild swine), species with wide distribution and high density, which allow the spread of tick-borne viruses in Europe (Kriz et al., 2014). In this sense, viruses belonging to families Flaviviridae (tick-borne encephalitis), Nairoviridae (Crimean–Congo hemorrhagic fever), and Phenuiviridae (severe fever with thrombocytopenia) have emerged in… Read more

Risk Factors for Antimicrobial Resistance in Turkey Farms: A Cross-Sectional Study in Three European Countries

Investigation article published in Antibiotics


Food-producing animals are an important reservoir and potential source of transmission of antimicrobial resistance (AMR) to humans. However, research on AMR in turkey farms is limited. This study aimed to identify risk factors for AMR in turkey farms in three European countries (Germany, France, and Spain). Between 2014 and 2016, faecal samples, antimicrobial usage (AMU), and biosecurity information were collected from 60 farms. The level of AMR in faecal samples was quantified in three ways: By measuring the abundance of AMR genes through (i) shotgun metagenomics sequencing (n = 60), (ii) qua… Read more

Long-term determinants of the seroprevalence of the bluetongue virus in deer species in southern Spain

Investigation article published in Research in Veterinary Science


Bluetongue is a vector-borne disease affecting domestic and wild ruminants, with a major socioeconomic impact. Endemic circulation of the bluetongue virus serotype 4 (BTV-4) and BTV-1 have occurred in Spain since 2004 and 2007, respectively. However, epidemiological studies have seldom been approached from a long-term perspective in wild ruminants. A total of 881 deer (red deer and fallow deer) were necropsied from 2005 to 2018 as part of the DNP health-monitoring program. Serum samples were tested for antibodies against BTV with the aims of assessing the temporal trend and to evaluate the mod… Read more

Monitoring of Antimicrobial Resistance to Aminoglycosides and Macrolides in Campylobacter coli and Campylobacter jejuni From Healthy Livestock in Spain (2002–2018)

Frontiers in Microbiology publish this investigation article


Antimicrobial resistance (AMR) in Campylobacter spp. (Campylobacter coli and Campylobacter jejuni) is a concern due to its importance in public health, particularly when it involves aminoglycosides and macrolides, drugs of choice for treatment of human cases. Co-resistance to these two antimicrobial classes involves transfer of genetic elements and/or acquisition of mutations in different genetic loci, which can in turn spread through vertical or horizontal gene transfer (HGT) phenomena, with each route having different potential implications. This study aimed at evaluating the association bet… Read more

The wildlife-livestock interface on extensive free-ranging pig farms in central Spain during the

Investigation published in Transboundary and Emerging Diseases


The effective management of shared pathogens between wild ungulates and livestock requires the understanding of the processes of interaction between them. In this work we studied the interspecific frequency of interaction (ifreq) and its spatio‐temporal pattern between wild and domestic ungulates that coexist in free‐ranging farms. For this purpose, 6 red deer, 6 wild boar, 8 Iberian pigs and 3 cattle were monitored using GPS devices during the “montanera” period (the period in which Iberian pigs are maintained in extensive conditions to feed on acorn). The ifreq was quantified for… Read more
