Know more

JRU BIPAR's activities are focused on the study of Host-Pathogen Interactions, as well as on the detection, characterisation and circulation of pathogens:
- food-borne zoonotic parasites.
- vectors (ticks, mosquitoes) and the pathogens vectored by them (bacteria, parasites and viruses).

The JRU also hosts :
- a National Reference Laboratory for food-borne parasites, excluding Echinococcus
- an WOAH collaborating centre on food-borne zoonotic parasites, which shares reference research projects with the Paralim team and carries out national and international reference activities.

RESEARCH

The UMR BIPAR (set up in 1998) develops :

• from fundamental to applied research to improve our understanding of hosts-pathogens interactions (at the molecular, cellular, tissue/salivary gland or food matrix, host and ecosystem levels, including the microbiota of vertebrate and invertebrate hosts) and the circulation of these pathogens.
• innovative control strategies for ticks, arthropod-borne pathogens and food-borne zoonotic parasites (improved detection and monitoring, 'universal' vaccine strategies or in target species, 'ecological' alternatives to antiparasitic treatments and acaricides, etc.).

For several years now, the JRU has been developing more ecosystemic approaches for the research themes of each team, in particular with the emergence of studies of the microbiota of the vertebrate host (Giardia/Cryptosporidium) or the invertebrate host (ticks). In addition, various -omics approaches have been introduced, several of which have been specifically developed in our unit.

This has led to several current or future applications, some of which are particularly innovative, in the fields of diagnosis/screening (e.g. Trichinella), surveillance using high-throughput tools (agents transmitted by different arthropod vectors), differentiation between zoonotic and non-zoonotic strains (B. henselae) or between abortive and non-abortive strains (A. phagocytophilum), the development of vaccines (anti-tick vaccines, tick microbiota vaccines and 'universal' antimicrobials) or innovative anti-parasite therapeutics (Cryptosporidium, Giardia).

The  JRU benefits from state-of-the-art equipment acquired with the financial support of the Ile de France Region, the EnvA and the ANSES (DIM Malinf and DIM 1Health), such as a confocal microscope, a flow cytometer, a Maldi-Tof mass spectrometer and a tick rearing platform (Tickarium). Our laboratories are also equipped for cell culture (cell lines or primary cells), molecular biology, immunology, cell biology and biochemistry.

REFERENCE ACTIVITIES

The JRU also hosts a National Reference Laboratory (NRL) for food-borne parasites, excluding Echinococcus, and a WOAH Collaborating Centre for food-borne zoonotic parasites (international mandate obtained in 2014), which shares research-reference projects with the Paralim team and is responsible for national and international reference activities.
