Microbial quantitation of colostrum from healthy breastfeeding women and milk from mastitis patients

Colostrum is rich in microbiota. However, the quantity of microorganisms including both opportunistic pathogens and commensal mammary microbiota remains fluctuant during lactation. And once dysbiosis occurred in these microorganisms, a process in which the population of opportunistic pathogens increases while other bacteria, commensal mammary microbiota decrease. Lactation mastitis might occur. There were few literatures of microbiota in Chinese breastfeeding women. So this study aimed to investigate the quantity of microbiota in the colostrum from healthy breastfeeding women and the milk from mastitis patients in China.
