BIOL6076 Biomedical Parasitology

Module Overview

This module will introduce the main issues in parasitology, the host parasite interaction and how it drives evolutionary changes, the disease burden caused by parasites and how parasite infections can be treated/ minimised.

Aims and Objectives

Module Aims

The aim of this module is introduce third year students to the main clinically relevant parasite classes, it will consider their lifecycles, the human/veterinary pathology caused and the treatment methods both of the primary and where applicable intermediate hosts and environment. It will give an understanding of vector borne disease. The module will consider the interaction and evasion methods used by parasites in respect to the immune system and chemical control. It will consider the evidence of possible benefits gained by parasitism. Finally it will demonstrate examples of host:parasite coevolution and consider the likely changes in parasite risk the UK in the light of environmental change.

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

  • Explain the lifecycles of the main clinically relevant parasite classes
  • Explain the human/veterinary pathology caused by the main clinically relevant parasites
  • Explain the treatment methods/prevention utilising both the primary and where applicable intermediate hosts and environment
  • Give examples of vector borne disease, where parasitism is significant in the disease
  • Explain interaction and evasion methods used by parasites in respect to the immune system and chemical control
  • Give examples of the possible benefits gained by parasitism
  • Give examples of host:parasite coevolution
  • Explain possible changes in parasite risk the UK due to environmental change

Syllabus

1/ Definition of parasite and parasitology and understanding of their worldwide and UK importance for human/ animal health and their role in current hygiene policy 2/ An understanding of the main classes of human parasite and examples of the most relevant parasite induced diseases including- Kinetoplastids (trypanosomes), Plasmodia, Amoebia, Helminths (Cestodes-tape worms, Schistosomes, Nematodes), Ectoparasites (insects -lice, fleas etc, Arachnia -ticks / mites) 3/ Examples of the various methods of pharmacological treatment in the host, also other protective counter measures 4/ Parasites effects on the immune system and parasite immune evasion 5/ Examples of parasite and host interactions and co-evolution (eg Cat-Mouse-Human behaviour and Toxoplasma) 6/ Effects of climate change on parasite risk
