Samples. Four CXCR1c.980AG heifers and four CXCR1c.980AG heifers were inoculated with PBS, a Staphylococcus chromogenes strain isolated from a chronic intramammary infection (S. chromogenes IM), a Staphylococcus chromogenes strain from a teat apex (S. chromogenes TA) and a Staphylococcus fleurettii strain in a split-udder design to study differences between coagulase-negative staphylococci. For this research, somatic cells were isolated from milk samples taken 1 h before and 12 h after inoculation from quarters (to be) inoculated with PBS or S. chromogenes IM.
