ECOPHIP is focusing its research activities on the intestinal parasitic protozoa Blastocystis and Cryptosporidium, which currently represent major socioeconomic and public health problems. Both parasites are responsible for gastrointestinal infections which, in the case of Cryptosporidium, can be serious or even fatal in children and immunocompromised patients. However, these parasites are still poorly studied and generally overlooked by health authorities, while little or no treatment is effective against these parasites. Moreover, these two parasites, presenting a great genetic diversity and being able to colonize many hosts, also represent relevant models to investigate a major biological question in the field of "Ecology of Health": what is the nature of the genetic diversity of these latter parasites and its impact on the circulation and pathogenicity of different species and genotypes? The current and future work of ECOPHIP, which has the particularity of combining “field studies" and "laboratory research", aim to clarify the molecular epidemiology of these parasites, their circulation in human and animal populations as well as in the environment (research of transmission risk factors) and their pathophysiology while identifying molecules and mechanisms involved in the pathogenesis of these parasites. The goal of ECOPHIP is to provide strategies to implement urgent prevention and control measures to significantly reduce the incidence of these parasites.To carry out its activities, ECOPHIP combines molecular epidemiology and phylogeny, comparative genomics, transcriptomics and proteomics, metagenomics and cell and molecular biology approaches together with the development of in vivo, ex vivo and in vitro study models. ECOPHIP has developed a large and well-targeted network of regional, national and international collaborations. Finally, because of its rare expertise in protistology, ECOPHIP is requested for specific collaborations, in particular in the context of the molecular identification of parasitic protozoa of interest in human and animal health or as coordinator / partner of funded projects funded in the fields of parasitology (fish parasites) and environmental parasitology.

Gut eukaryome: the special role of intestinal protozoa in the gut microbiota
Awareness of the roles that host-associated intestinal microbes play in biology and health has increased in recent years. However, microbiome research has focused essentially on bacteria, and overall, little is known about the role of host-associated eukaryotes outside the field of Parasitology. However, microeukaryotes are common inhabitants of our gut rarely associated with clinical signs of disease. In particular, our team has shown that Blastocystis protozoa, whose pathogenicity is controversial, are associated with positive effect on intestinal bacterial diversity and changes in the composition of the gut microbiome, and would therefore be considered members of a healthy gut microbiota. The study of the diversity and role of these intestinal microeukaryotes on human and animal health is currently supported in the team ECOPHIP by the Hauts-de-France Region (STIMulE 2020 exploratory project funding) as well as by the SATT Nord (co-maturation program).

CA21105 - Blastocystis under One Health (OneHealthBlastocystis)
The ECOPHIP team is the only French team to have integrated the COST program Blastocystis under One Health 2022-2026. Within this framework, Dr Magali Chabé is a member of the management committee and co-leader of the working group "Blastocystis collection and database". Dr Eric Viscogliosi will be involved in the working group "Mapping Blastocystis epidemiology and diagnostics
Description
Blastocystis colonizes at least one billion people making it the most prevalent intestinal microbial eukaryote. Emerging data indicates higher prevalence in animals. A high proportion of carriers are asymptomatic. Despite numerous studies, pathogenicity of Blastocystis remains controversial. Currently, at least 26 genetic subtypes (STs) exist. Of these, ST1-ST9 and ST12 have been found in humans, while the rest have been isolated only from non-human hosts. Information on prevalence, geographic distribution and host specificity of STs is incomplete. Significant gaps also exist on environmental presence of Blastocystis. Collectively, this paucity of data blurs the Blastocystis landscape considerably. The specific objectives of this framework are to: (1) Support advancement of Blastocystis research by bringing together professionals from various disciplines and countries; (2) Foster information sharing on current methodologies, especially in the areas of subtyping, host-Blastocystis-microbiome interactions and Blastocystis-omics; (3) Promote capacity building via a transdisciplinary network of international collaboration; (4) Open avenues of communication with veterinarians, physicians and general public. By the end of this initiative, participants will be able to: (i) Apply state-of-the-art tools for molecular identification of Blastocystis; (ii) Harmonise methodologies for subtyping Blastocystis and identifying its role within the gut; (iii) View Blastocystis under One Health approach; (iv) Generate novel hypotheses to test role of Blastocystis in the gut ecosystem, health and disease.

Cryptosporidium and digestive cancer
The Apicomplexan intracellular parasite Cryptosporidium is considered as one of the major causes of mild and severe diarrhea worldwide but less attention has been paid to its tumorigenic potential despite the high exposure of humans and animals to this ubiquitous parasite. Particularly, our team has reported that Cryptosporidium parvum can induce invasive gastrointestinal and biliary adenocarcinoma in a SCID mouse model as soon as 20 days Post-Infection (depending on the virulence of the Cryptosporidium strain) and low grade intraepithelial neoplasia in an intestinal ex vivo model. Moreover, Cryptosporidium infections may induce cell transformation in humans. Indeed, recent epidemiological studies showed a high prevalence of infection in patients with gastrointestinal cancer recently diagnosed and before any treatment. Our research has concentrated on the study of the physiopathology of Cryptosporidium and on the identification of the molecular signature of Cryptosporidium parvum-induced digestive cancer
