Treatment of Bacterial Cystitis in Fully Automatic Mechanical Models Simulating Conditions of Bacterial Growth in the Urinary Bladder

摘要

Two fully automatic models are described in which growing cultures can be continuously diluted and periodically discharged producing conditions of growth resembling those of the infected urinary bladder. Both models generate a continuous record of the opacity of the growing culture and the second model also generates a record of the Eh. The effect of adding ampicillin to a sensitive strain of Escherichia coli growing in these conditions is described and the relation of the results to human therapy is discussed.
