Description: Segment 1 Firstly the bacillus typhosus is shown at several magnifications, followed by a title, Agglutination, with footage illustrating this method (used presumably to form a diagnosis). The title for Cholera Bacillus is more ornate (suggesting that it originated as a separate film) and the descriptive captions more detailed: 'The cholera microbes here reproduced from cultivations in broth, were derived from cases of cholera at Bombay' 'The Cholera bacillus in the intestines of the sick, or in a fresh cultivation in broth, moves very freely by the help of a vibratile. This cilium or lash-like process cannot be seen in the picture, because it moves too rapidly and is very fine' 'When cultivated for a considerable time some bacilli are to be seen much longer than the others and forming more or less complete circles' 'After some time the microbes show a tendency to clump together finally they cease to move.' The Cholera bacillus are shown at various magnifications. Time start:00:00:00:00 Time end: 00:05:23:22 Length: 00:05:23:22
