In plain words
Mammary dysbiosis is a proposed change in the mix of bacteria inside the breast's milk ducts. The idea is that some types, such as , can grow in a sticky film called . That film can keep a duct infected. Researchers think antibiotic use, , and milk sitting in the breast can make the change more likely. It is an idea, not a settled diagnosis. You do not need to know your bacteria to get care. If you have breast pain, redness, or fever, call your provider the same day.
The deeper version
Mammary dysbiosis has been proposed to describe a shift in ductal microbiota toward Staphylococcus aureus or coagulase-negative staphylococci that form biofilms inside ducts, which may sustain . The hypothesis draws on small culture and sequencing studies of milk and nipple skin that show differences in the milk microbiome during compared with healthy lactation. Causality has not been shown. Contributing factors discussed include antibiotic exposure, milk stasis from oversupply, and . The Academy of Breastfeeding Medicine mastitis protocol (2022) manages the condition clinically and does not rely on microbiome testing. The main controversy is whether drives mastitis or follows it.
