Virginia is a Research Fellow at RVC focus in the development of new vaccines in the poultry sector by the implementation of molecular tools for gene editing into Eimeria parasites (coccidian) and the development of in vitro models to reduce the use of animals in the study of this parasite.
Virginia graduated in Spain in 2003 as Agronomic Engineer specialised in zootechnics (technology of animal husbandry) and biotechnology (Universidad Politecnica de Madrid, UPM). Before starting her postgraduate, she hold a studentship in bacteria proteomics in the Department of Biotechnology (UPM) and worked as research assistant in prion biology at the Centre for Research in Animal Health (CISA, INIA). She did her doctoral courses (MSc equivalent) in Veterinary Sciences (Universidad Complutense de Madrid, UCM) including modules in applied immunology, clinical microbiology and parasitology and microorganisms genomics and proteomics. Afterwards, she completed her PhD in the Department of Animal Health (UCM) in 2011, testing transgenic strains of Neospora caninum (Apicomplexa parasite) as live vaccines and identifying new vaccine targets by proteomic approaches. Thereafter, Virginia moved to The Royal Veterinary College as postdoctoral researcher in Professors Fiona Tomley and Damer Blake lab, working in different molecular parasitology and vaccine development of Eimeria species (Apicomplexa parasite). In 2017 she was appointed as Research Fellow in Vaccinology in the Department of Pathobiology and Population Sciences.
In addition, Virginia hold a Pedagogic Certificate (UCM, QTS equivalent) and is Associate in Higher Education Academy in Veterinary Education (RVC). She is expecting to complete the PG Certificate in Veterinary Education in the academic year 2018-2019.
Virginia’s current research is focus on the biology and control of Coccidia (Apicomplexa) parasites affecting animals and humans. To promote the first guiding principle for the ethical use of animals in sciences (the 3Rs) by replacing and reducing the use of animals, she is been developing a robust, rapid and quantitative high throughput in vitro assay for the evaluation of anti-parasitic effects of novel treatments (drugs, natural compounds, specific antibodies) in Eimeria tenella (causing coccidiosis in chickens). This assay combines quantitative PCR, reverse transcription qPCR and semi-automated analysis of images (funded by Houghton Trust Small Research Grant).
She leads research in transgenesis in E. tenella, developing protocols for the use of this parasite as delivery vector for antigens of other avian pathogens. She has detected humoral immune response in chicken immunised with Eimeria carrying antigens of the infectious bursal disease virus and the infectious laryngotracheitis virus, however, consistency and magnitude of immune response stimulated by transgenic Eimeria vaccination should be improved. For that, she has added targeting signals for delivery to the cell surface or secretion, which could to improve the exposition of the antigen and therefore its recognition (funded by the BBSRC BB/H020195/2). She has also used protein fusions with fluorescent reporters for protein localization in a single step that could significantly simplifying the conventional time-consuming procedures for protein characterization and avoiding the use of animals for the production of antibodies.
In addition, with the aim of producing reliable, good quality samples for detailed proteome and transcriptome studies she has optimised in vitro methods of infection and development for sporozoites of E. tenella and Toxoplasma gondii. She has standardised RNA interference and inhibition assays for the investigation of functional roles of parasite and host proteins identified in the previous approaches for identification of new therapeutic targets (funded by the BBSRC BB/L00299X).

Virginia co-supervise a PhD student (Alana Burrell) working in the application of powerful 3D imaging methods, in particular serial block face-scanning electron microscopy (SBF-SEM) and electron tomography (ET), alongside conventional imaging techniques to study in detail the processes of E. tenella invasion and intracellular growth (funded by RVC Internal PhD Studentship). She has also supervised several undergraduate research projects associated to some of her research lines (BSc Biological/Bioveterinary Sciences, BSc in Comparative Pathology and BBSRC Research Experience Placements) and participate in other teaching activities (tutor of undergraduate students, facilitator in directed learning sessions and practicals).
