Figure 3From: Local host response following an intramammary challenge with Staphylococcus fleurettii and different strains of Staphylococcus chromogenes in dairy heifers Proportion of apoptotic neutrophils. The proportion of apoptotic neutrophils (% apoptotic PMN) was determined in quarter milk before and after experimental intramammary challenge with Staphylococcus fleurettii, S. chromogenes TA (teat apex strain), S. chromogenes IM (intramammary strain) and phosphate-buffered saline (control). The error bars represent the standard error of the mean (+SEM).Back to article page
