Time course of S. aureus concentration in milk. CFU were numbered by the plate count method. By 18 hpi, two groups of goats segregated on the basis of CFU concentrations (p < 0.01, Mann & Whitney test). The higher CFU group was referred to as the uncontrolled infection (UI) group. It comprised the four goats that developed gangrenous mastitis plus goat number 6, which labored to control the infection.
