Here you can choose a group of parasites from the navigation tree (e.g. protozoa / malaria or helminth / nematodes). Under “images” you then select a parasite from the pull-down menu. Your job is to find this parasite on the virtual slide. The magnification is your choice. To zoom the picture you move the bar on the right side of the microscope. If you would like to check whether your identification is correct then you press “show labels” under “labels”. There is a hidden legend (giving more information) which you get by clicking on the label.
