Type of course

Master course for biology- and aquamedicine students.

Course overlap

If you pass the examination in this course, you will get an reduction in credits (as stated below), if you previously have passed the following courses:

FH-203 Parasitology/epidemiology 10 ects

Course content

The course gives an overview of parasitic animals (protozoan and multi-cellular animals) with a focus on their biology, ecology, strategies for transmission (life-cycles) and potential pathogenic effects on their hosts. The examples are given primarily from aquatic host-parasite systems, and the most common parasites of humans. Additionally, the course gives a basic introduction to epidemiology, immunology and ecological interactions between parasites and their different hosts.

Objectives of the course


  • to understand the term parasitism as one out of several symbiotic relationships between animals and to define types of life cycles and categories of hosts
  • basic knowledge of the biology and ecology of parasitic animals (protozoan and multi-cellular animals) with a focus on form, function, life cycles, transmission and their role in the ecosystem
  • detailed knowledge of the most common parasites in fish and other aquatic animals in both freshwater and marine environment and their potential pathogen effects on hosts
  • know the basics within epidemiology/ecological parasitology such as terms related to populations, statistic parameters, distribution patterns, rates of transmission, and regulation of host/parasite populations


  • Know how to dissect fish and invertebrate hosts with different techniques for identification of parasite taxa and counting/estimating the number of parasites
  • Be able to report (written and oral presentations) the occurrence and impact of parasites within a host population and provide critical interpretations using appropriate epidemiological terms and statistics.

General competence

  • know the IMRAD-system for science publishing and through this convey own data and interpretation of results (via a poster presentation)
  • know how to use scientific publications as background for aims or hypotheses in practical studies
  • communicate how parasites can be problematic for wild and farmed animals, and humans, and how parasites can regulate ecological communities.
