Urea Broth Base is for the detection of urease production, and is not intended for use in the diagnosis of disease or other conditions in humans. This is a liquid version of Christensen’s medium (NCM0180) introduced by Maslen in 1952. This modification allows inoculation by Pasteur pipette, and it is easier to detect contamination in a fluid rather than in a slope. Maslen also claimed that it is easier to detect positive results.
