Epidemiological situation of equine piroplasmosis in Spain: where is the risk?

Oral communication in XI International Equine Infectius Diseases Conference

Background: Theileria equi ( T. equi) and Babesia caballi (B. caballi) cause equine piroplasmosis (EP), one of the most important tick-borne diseases of horses worldwide, due to its negative impact to the equine industry [1]. Although infections with these protozoa have been reported for years in Spain, epidemiological studies have only been carried out in certain regions [2]. Objectives: To determine the prevalence of these parasites in asymptomatic horses in Spain and to identify potential risk factors associated with seropositivity to EP. Study design: Cross sectional. Methods: Horses r… Read more

Evaluation of PCR assays for Campylobacter fetus detection and discrimination between C. fetus subspecies in bovine preputial wash samples

Investigation article published in Theriogenology

Campylobacter fetus is a zoonotic pathogen found in cattle, in which it is one of the main causes of infectious infertility. Most diagnostic laboratories use PCR as quick easy tool for C. fetus identification. However, there is no standardized PCR assay for C. fetus detection and subspecies differentiation, hindering the comparison of results. In this study, we evaluated selected PCR assays targeting the 16S rRNA, gyrB, cpn60, cstA, cdtB and nahE genes for C. fetus identification and ISCfe1, sapB2, parA and virB11 for subspecies differentiation. Analytical sensitivity and specificity were asse… Read more

Molecular diagnosis of bovine genital campylobacterosis: comparative study of three PCR techniques

Degree Final Project defended by Natalia Lopez García

Campylobacter fetus is the causative agent of bovine genital campylobacteriosis (BGC), a venereal disease that causes infertility in cattle. It is also a zoonotic pathogen. Traditionally, culture and identification through biochemical tests are considered the “gold standard” technique to identify C. fetus. The main drawback of this methodology is its low sensitivity since C. fetus has very demanding growth conditions. In addition, biochemical tests for identifying both species and subspecies are scarce and frequently throw ambiguous results. There are different molecular techniques described … Read more

Seroprevalencia de muermo y durina previa a la exportación de caballos en España

Carolina Belart Sainz defended this Degree Final Project

Glanders and dourine are infectious diseases that affect equines and are caused by Burkholderia mallei and Trypanosoma equiperdum, respectively. Transmission of B. mallei occurs mainly due to consumption of contaminated water or food, through skin and mucous membrane lesions, by inhalation, and by fomites, while transmission of T. equiperdum occurs by venereal route. Both agents produce asymptomatic carriers and, in the case of glanders, disease in human beings. There are different techniques available for the diagnosis of glanders and dourine, the main one being complement fixation test (CFT)… Read more

The spatial ecology of red deer under different land use and management scenarios: Protected areas, mixed farms and fenced hunting estates

Investigation article published in Science of the total environment

The knowledge regarding the spatial ecology of red deer (Cervus elaphus) in different environments is crucial if effective management actions are to be designed. However, this knowledge continues to be scarce in the complex contexts of mixed land use and management circumstances. This study describes the spatial ecology of red deer monitored using GPS collars in Mediterranean ecosystems of South-Central Spain, considering the effect of individual and seasonal (food shortage period, rut, hunting season and food abundance period) factors on different land use and management scenarios, namely pro… Read more

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

African swine fever vaccine: Turning a dream into reality

Investigation published in Transboundary and Emerging Diseases

African swine fever (ASF) is currently threatening the swine industry at a global level. The disease originated in Africa has spread to Europe, Asia and Oceania, since 2007, reaching a pandemic dimension. Currently, the spread of ASF is unstoppable and that the development of a safe and effective vaccine is urgently required. The objective of this paper is to review the vaccine candidates tested during the 20th and 21st centuries, to identify the strengths and weaknesses of these studies and to highlight what we should learn. Several strategies have been explored to date, some of which have sh… Read more
