Looks at bacteria, showing the range of behaviours seen in living bacteria, how they obtain nutrients through ‘external digestions’ and how to use sterile techniques for culturing them. Shows the role of...
A demonstration by phase contrast, time-lapse cinematography of the action on bacteria of penicillin and the broad-spectrum antibiotics.
Shows an interesting example of a host-parasite interaction: infection of an amoeba nucleus by bacteria. An Encyclopaedia Cinematographica film.
Demonstrates the inoculation of media with bacteria.
Explains the problem of antibiotic resistance and the mechanism and role of bacterial communication. Previously bacteria were thought to live in isolation, but a group of scientists discovered that bacteria...
Lambda bacteriophage are used to clone large fragments of DNA. Here, phage are isolated by first infecting a liquid suspension of bacteria. During incubation the bacteria are lysed by the phage. The phage...
Looks at bacteria and their varied effects on the real world, and their utilisation of resources. Describes the biology of common bacterial diseases. Discusses bacteria with respect to their usefulness in...
Bacterial plasmids are used to clone DNA. Here, large amounts of bacteria are cultured containing the plasmid. The numbers of plasmids in the bacteria are then amplified by the addition of chloramphenicol....
A sample of purple red bacteria is collected and placed in an air-tight culture flask. Using cinemicroscopy various experiments on the bacteria are shown. Chromatium and thiospirallum are examined....
Examines the serious threat posed by antibiotic-resistant bacteria (suberbugs) and explains the evolutionary principles behind their development, why the problem is getting worse and how it is being dealt...
