About this work

Description

Brian W Bainbridge lectures on bacteriophage lambda (phage lambda), a virus which attacks the gut bacterium Escherichia coli (E. coli). His main aim is to illustrate chromosome behaviour in this bacteriophage. Utilising animated diagrams and electron micrographs he describes its appearance, life cycle and ability to attack E. coli in the gut. It is a short and rather intense lecture, primarily technical in content. 2 segments.

Notes

This video is one of around 310 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and 1980s, thus constituting a contemporary medical-historical archive of great interest. The lectures mostly take place in a small and intimate studio setting and are often face-to-face. The lecturers use a wide variety of resources to illustrate their points, including film clips, slides, graphs, animated diagrams, charts and tables as well as 3-dimensional models and display boards with movable pieces. Some of the lecturers are telegenic while some are clearly less comfortable about being recorded; all are experts in their field and show great enthusiasm to share both the latest research and the historical context of their specialist areas.

Contents

Segment 1 Bainbridge talks in voice over while showing an animated diagram of the structure of bacteriophage lambda then over an electron micrograph of phage lambda and a further animated diagram of phage lambda chromosomes. He describes and shows the appearance of the phage lambda in detail. An electron micrograph of a thin section of E. coli cells is shown, then over an animated diagram of phage lambda, Bainbridge describes how it divides; he likens its presence in the body to the presence of the herpes virus which can lie dormant and recur at different stages of life.

Segment 2 Bainbridge narrates over an animated diagram showing the linearisation of the phage chromosome into a phage particle, then over an animated diagram showing a transducing phage. Bainbridge then summarises the main points of the lecture. Time start: 00:05:15:00 Time end: 00:08:38:21 Length: 00:03:23:21
