  • Detection of bacterial vaginosis
    Patent number: 6951759
    Abstract: There is disclosed a method for detecting the presence of bacterial vaginosis in a female subject comprising the steps of: obtaining a sample from the vaginal region of the subject; detecting acetic acid present in the sample; and correlating the presence of detected acetic acid with the presence of bacterial vaginosis.
    Type: Grant
    Filed: August 14, 2002
    Date of Patent: October 4, 2005
    Assignee: Osmetech PLC
    Inventors: Paul James Travers, Amjad Nissar Chaudry, Andrew John Tummon, Martin James Henery
  • Determining infections in liquid samples by detecting short-chain fatty acids and ammonia in the headspace associated with the liquid sample using polymer sensors
    Patent number: 6921668
    Abstract: A method for determining the presence of an infection in a liquid sample comprising the steps of: lowering the pH of the liquid sample so as to drive short-chain fatty acids present in the liquid sample, acetic acid in particular, to the gaseous phase; detecting short-chain fatty acids, ammonia and, optionally amine species present as gases in a headspace associated with the liquid sample using a detector which is sensitive to the presence of short-chain fatty acids, ammonia and, optionally, amine species, particularly conductive and semi-conductive polymer sensors; and correlating the presence of detected short-chain fatty acids, ammonia and, optionally, amine species with the presence of the infection.
