New approaches to get around roundworms
Descriptif
Parasitic roundworms, also termed ascarids, share many biological and pathological features, and so a systematic collaborative approach to the study of these offers great synergistic potential in the development of new options for controlling these infections. This group of parasites are highly prevalent and of great clinical importance in human and animals, e.g. pigs, horses, chickens, dogs and cats. Some, such as Ascaris spp. are zoonotic and it is estimated that > 800 million people are at risk of infection with Ascaris lumbricoides. To promote the advancement of science and foster international multi-disciplinary research collaborations to combat diseases caused by ascarid worms, we propose the development of an international collaboration entitled ‘The Ascarid Research and Training Initiative (ARTI)’.
To facilitate this, we will hold a scientific conference including up to five workshops dedicated to the establishment of focus working groups on specific research themes addressing the state of the art in e.g. immune response, drug action and resistance as well as genomic/transcriptomic analyses of ascarids. ARTI will include researchers working on fundamental as well as applied research issues of ascarid infections in human and animal hosts. Academic, private/industrial and governmental research institutions will be involved. Furthermore, linking the conference with a workshop on ‘Approaches and perspectives of Caenorhabditis elegans as a tool for ascarid research’ will promote technology transfer and interdisciplinary research collaborations betw. parasitologists and those working on the ‘model’ nematode species.
