Chemokine (C-X-C motif) receptor 1 (CXCR1 or IL-8RA) plays an important role in the bovine mammary gland immunity. Previous research indicated polymorphism > G in the CXCR1 gene to influence milk neutrophils and mastitis resistance. In the present study, four heifers and four heifers were experimentally infected with Staphylococcus chromogenes. |
