D values (decimal reduction time; the time required to kill 1 log concentration of bacteria) were determined for both human and bovine strains (Dominic, Ben, BO45, and ATCC 19698) of Mycobacterium paratuberculosis in 50 mM lactate solution (pH 6.8) and in milk at four temperatures (62, 65, 68, and 71 degrees C). Viable M. paratuberculosis organisms were quantified by a radiometric culture method (BACTEC). Thermal death curves for the M. paratuberculosis strains tested were generally linear… CONTINUE READING
