Welcome Address

Dear colleagues,

We would like to invite you to take part in the 15th International Congress of Protistology. This congress is organized every four years and always attracted the protistologists from various field of our discipline creating friendly and creative protistological atmosphere.

The congress is also the 2017 Annual Meeting of the International Society of Protistologists (ISOP) and will include the ISoP sponsored Hutner Lectures, Past President‘s Address, Members Meeting, and symposia.

The research on has a long tradition in the Czech Republic and the first congress of the ICOP series took place in Prague in 1961. We are happy that after almost 60 years the congress will come back to the place where it started. We will do our best to prepare for you a pleasant venue in the heart of our historical capital.

On behalf of the local organizers
