the present study demonstrates that live s. aureus of the cowan 1 strain binds amounts of collagen per organism equivalent to those demonstrated previously in heat-killed , formaldehyde-fixed bacteria but has an affinity over 100 times greater , with kd values of 9.7 x 10 ( -11 ) m and 4.3 x 10 ( -8 ) m for live and heat-killed organisms , respectively .
