EU-COST-NUS Workshop: Blastocystis Culture & Applications

Total Registrations: 29


Blastocystis is an emerging protistan parasite found in a bewildering array of mammals, birds, reptiles, amphibians, and insects. In humans, it colonizes the large intestines and may be associated with asymptomatic carries status of actue bowel diseases. Much of what is known about Blastocystis molecular and call biology, biochemistry, drug susceptibility, host-parasite interactions and, more recently, role in the gut microbiome, is possible through the use of purified (axenic) cultures. Axenization is a laborious and long drawn process, and hence, there are only a handful of laboratories worldwide that possess axenic cultures of Blastocystis. Pure cultures are also vital in implicating a specific role of Blastocystis in in vitro and in in vivo host-parasite studies.
The aim of this 3-day workshop is to provide hands on exposure to our participants on methods related to Blastocystis axenic culture and its applications. Our workshop will consist of scientific talks and discussions during the morning sessions, and will continue with laboratory sessions in the afternoon. Topic covered include culture protocols, bioimaging, genetic manipulation, host-parasite interactions, and microbiome. Experts in these areas will deliver lectures during the morning sessions and instructors will guide participants on related methodologies during the laboratory session.
This event is part of an EU-COST initiative to train our biomedical community on One Health aspects of Blastocystis research, and is generously funded by NUS School of Medicine and Blastocystis One Health COST grant. Registration is limited to faculty and early career scientists (PhD students & Postdocs) under the EU-COST Blastocystis One Health project. Interested participants who are not part of this project will be considered on a case-by-case basis. Registration outcomes will be announced by early April 2023.

Our Event Speakers

Keynote Speaker - Associate Professor Hisao YOSHIKAWA

Associate Professor Hisao Yoshikawa was born in Osaka. He obtained a bachelor and master degree of Biology in Kobe and then moved to a Ph.D. course as a student in Medical Zoology, equivalent to Parasitology, in Kyoto Prefectural University of Medicine, where he worked on Pneumocystis carinii, especially ultrastructure of this unclassified microbe at that time. He was skillful for freeze-fracture and immune-electron microscopy, and his expertise had contributed to the development of Hitachi freeze-fracture apparatus FR-7000. After he moved to Nara Women’s University, he focused on Blastocystis research, especially for morphology, epidemiology, and molecular phylogeny. While there, he temporarily moved in Dr. Don Graves laboratory, University of Oklahoma for the collaborated research on Pneumocystis carinii under the NIN grant for one year. He has published about 90 articles and four book chapters including editor, most of which are peer-reviewed. He will be retiring at the end of March this year.

Keynote Speaker - Dr. John Anthony YASON

Dr. John Anthony YASON finished his PhD from Yong Loo Lin School of Medicine, National University of Singapore. He was also a Postdoctoral Research Fellow at the Laboratory of Molecular and Cellular Parasitology, Department of Microbiology and Immunology in the same University under the supervision of Assoc. Professor Kevin SW TAN. He focused his research on Blastocystis and later on studied its interactions with host cells and gut microbiota. He has previously worked on protistan parasites and currently doing epidemiological surveys on pathogens linked to neglected tropical diseases. He was also a consultant for COVID-19 Diagnostic Lab in the Philippines. He is currently the Dean of the Institute of Health Sciences and Nursing and teaches Advanced Microbiology and Research Methods courses at Far Eastern University in Manila, the Philippines.

Keynote Speaker - Dr. Jonathan LEE Wei Jie

Dr. Jonathan Lee is an early-career clinician scientist at National University of Singapore (NUS) Medicine, a principal investigator at iHealthTech, with a special interest in the field of Microbiome Medicine, as well as consultant Gastroenterology at National University Hospital (NUH), Singapore. He completed his Masters of Clinical Investigations, funded by the NMRC-MOH healthware award to study the mucosal microbiome profiles in patients with non-alcoholic fatty liver disease. He was then awarded the NRMC research fellowship from 2019-2021 to study host-microbita interactions in gastrointestinal diseases at the Broad Institute MIT-Harvard, under Professor Ramnik Xavier. Dr Lee also currently leads the NUH fecal microbiome transplant programme, and have multiple ongoing studies collecting fecal microbial samples from both healthy patients and patients with gastrointestinal diseases.

Invited Speaker - Prof Mark van der GIEZEN

Prof van der Giezen's research focuses mainly on intestinal microbiology and mitochondrial adaptations to anoxia as found in the animal gut. The topic of his PhD at the University of Groningen (the Netherlands) and his subsequent postdoc at the Natural History Museum (London, UK) was hydrogenosomes (unusual mitochondria) from anaerobic fungi. During his postdoc at Royal Holloway, University of London (UK), where he was involved in the discovery of mitosomes in Giardia, the topic shifted to human gut parasites (Entamoeba and Giardia). During his lectureship (~Assistant Professor) at Queen Mary, University of London (UK), he first worked with Blastocystis when he started a collaboration with Graham Clark. In 2007, he moved to the University of Exeter (UK) as a Senior Lecturer and became Associate Professor of Evolutionary Biochemistry. At Exeter, his work shifted partly to animal parasitology and the role of the microbiome in animal health. Since summer 2019, he is the Professor of Biological Chemistry at the University of Stavanger in Norway. Here he continues his research on important parasites for humans and animals and have established close research links with the academic hospital in Stavanger.

Invited Speaker - Prof Sven PETTERSSON
