UREA AGAR BASE (CHRISTENSEN) (AUTOCLAVABLE)

Description

Urea Agar is used to detect urease production. Urea Agar described by Christensen detected urease activity by all rapidly urease-positive Proteus organisms and also by other members of Enterobacteriaceae that exhibited a delayed urease reaction. This was accomplished by: a) adding glucose to the medium. b) decreasing the peptone concentration and c) decreasing the buffering system, as a less buffered medium detects even smaller amount of alkali.
