S. aureus counts in milk from LSCS (Low Somatic Cell Score) and HSCS (High Somatic Cell Score) goats at different time points. Mean S. aureus log10 CFU/ml in milk was measured in LSCS and HSCS goats at 0, 6, 12, 18, 24 and 30 hours post infection. S. aureus counts peaked at 18 h post-challenge with means of 5.8 log10 CFU/ml in LSCS line animals and 6.1 log10 CFU/ml HSCS selection line goats. From 18 h to 30 h this value remained constant (paired t-test).
