Gene expression profile in zebu dairy cows (Bos taurus indicus) with mastitis caused by Streptococcus agalactiae.

Mastitis is an inflammatory response in the mammary gland caused by an influx of somatic cells, composed mainly of neutrophils, macrophages and lymphocytes. The speed and efficacy of the host?s immune response to the invasive pathogen affects the establishment, persistence and severity of the infection. To characterize the gene expression and response mechanism to infection by Streptococcus agalactiae (S. agalactiae) in zebu dairy cows of the Gyr breed, we carried out a transcriptome study of the cells present in the milk from 17 animals
