This unit is available to students who have performed well in Intermediate Microbiology. This unit is designed to further develop an interest in, and understanding of, medical microbiology from the introduction in Intermediate Microbiology. Through an examination of microbial structure, virulence, body defences and pathogenesis, the process of acquisition and establishment of disease is covered. The unit is divided into three themes: 1. Clinical Microbiology: host defences, infections, virulence mechanisms; 2. Public health microbiology: epidemiology, international public health, transmission, water and food borne outbreaks; 3. Emerging and re-emerging diseases: the impact of societal change with respect to triggering new diseases and causing the re-emergence of past problems, which are illustrated using case studies. The unique aspect of this advanced unit that differentiates it from the mainstream unit is six tutorial style sessions that replace six mainstream lectures in the theme 'Emerging and re-emerging diseases'. These dedicated research-led interactive advanced sessions support self-directed learning and involve discussion around specific topics that will vary from year to year. Nominated research papers and reviews in the topic area will be explored with supported discussion of the relevance to and impact of the work on current thinking around emergence of microbial disease. The focus will be on microbial change that lies critically at the centre of understanding the reasons for the emergence of new diseases and challenges in an era of significant scientific ability to diagnose and treat infection. The practical component is identical to the mainstream unit and is designed to enhance students' practical skills and to complement the lectures. In these practical sessions experience will be gained handling live, potentially pathogenic microbes. Clinical tutorial sessions underpin and investigate the application of the material covered in the practical classes.
