The 13^th Host Pathogen Interaction Forum was held in Slavonice, Czech Republic, between April 16 and April 19, 2018. The Forum is traditionally organized by the Faculty of Military Health Sciences, Hradec Králové, Czech Republic, in collaboration with the Czech Immunological Society in Prague, Czech Republic. The venues for our Forums are selected with respect to historically significant areas of the Czech Republic. The Forum’s reputation has grown steadily over the years such that it has earned a place on the calendars of important scientists in the field of studies on pathogen interactions with their hosts. Due to the scientific orientations of the organizers, the forums bring together scientists working mostly with intracellular (bacterial as well as viral) pathogens.
