BSc Biomedical Sciences

The unit provides an in-depth covering of contemporary parasitology concentrating on the complex relationship between parasite and host. As such, it will be of interest to students who wish to learn more about these sorts of infectious diseases. Emphasis will be on the major parasites that cause human and animal disease covering molecular, cellular, in vitro and in vivo experimental approaches for the study of host parasite relationships. The strategies used by the hosts to control parasites and that the parasites use for immune evasion will form central themes together with an exploration of the consequences of parasitic disease for global health and current approaches of parasite control including vaccination.

The aim of the unit is to provide an in-depth understanding of contemporary parasitology concentrating on the complex relationship between parasite and host. Emphasis will be on the major parasites that cause human and animal disease covering molecular, cellular, in vitro and in vivo experimental approaches for the study of host parasite relationships. The strategies used by the hosts to control parasites and that the parasites use for immune evasion will form central themes together with an exploration of the consequences of parasitic disease for global health and current approaches of parasite control including vaccination. The emphasis of the course will be research led highlighting recent breakthroughs in the field.

The students will be able to:

• Appreciate the importance of parasitic infection in terms of global health.
• Understand contemporary approaches used to study the major parasites of human importance.
• Understand the broader consequences of parasite infection at both the individual host and host population level.
• Describe the current challenges of parasite control and the progress of anti-parasitic vaccines.
• Integrate data and information gained from different parasite species and from different experimental approaches to gain a clear overview of our current knowledge of parasitic disease and the major challenges that remain.

Protozoan and metazoan parasites are ubiquitous in both man and animals worldwide. The course will cover a variety of parasitic diseases concentrating on human disease as they constitute some of the great neglected diseases of the world as defined by the World Health Organisation. Lectures will cover different parasites at the molecular, cellular and population level concentrating on the active areas of contemporary research such as malaria vaccines, hookworm vaccines, the mechanisms underlying chronic parasite infections and the debilitating pathology caused by for example filariasis and schistosomiasis. The lectures will also examine the importance of parasitic infection to our current understanding of the hygiene hypothesis and how this impacts on global health in general. The course also considers new radical approaches for the treatment of many chronic illnesses such as inflammatory bowel disease and autoimmunity using parasites as therapeutic agents, and discusses the ethical issues it raises.

Written examination (80%): 1 hour and 30 minute written examination consisting of one essay from a choice. Written assignment (20%): Research paper summary. 

Individual summative feedback will be given on coursework that will contribute to the overall assessment. There will also be formative feedback in the form of a structured extensive question and answer session at the end of the course.

Further reading will be primarily based upon up to date articles from the literature.
