PUBMED DOIAdditional Information
Our group carries out research studies in the diagnosis, reference and epidemiology of zoonoses and emerging diseases, both indigenous and imported, caused by protozoa. Coordinates the study in the human field with the relevance of the animal field and the environment (One Health initiative), with special interest in Toxoplasmosis, a highly prevalent zoonosis (WHO lists it as the 3rd food-borne zoonosis in Europe), presents a complex epidemiological cycle and causes neurological, ocular and systemic symptoms. We carry out diagnostic and characterization studies of Toxoplasma gondii from human and animal cases, to obtain greater epidemiological information and analyze the possible relationship with virulence and pathology.
Cryptosporidium, Giardia, Blastocystis and Entamoeba histolytica cause gastrointestinal diseases, affecting children, immunosuppressed people and travelers. They can cause outbreaks. We develop diagnostic and characterization studies of isolates from humans and animals, from different areas and countries, to establish the presence of the main species and genotypes and the epidemiological situation. We are beginning the study of associations between these parasites and the intestinal microbiota.
The pathogenic Free-Living Amoebas, Acanthamoeba, Naegleria fowleri and Balamuthia mandrillaris, cause emerging diseases, highlighting the importance of the environment in transmission. They cause underdiagnosed neurological and ocular cases. The diagnostic and genotyping study of human and animal isolates that we are carrying out aims to establish the real prevalence, transmission routes and epidemiology.
