title: ATP measurements obtained by luminometry provide rapid estimation of Ureaplasma urealyticum growth.
abstract: ATP content obtained by luciferin-luciferase luminometry with commercially available reagents provided rapid estimates of Ureaplasma urealyticum populations. Each cell contained about 4.7 X 10(-18) mol of ATP. We could detect 10(4) CCU50 (color change unit50) per 100 microliters. We correlated urease activity with growth and confirmed the differential response of ureaplasma strains to Mn2+.
