Where does the organism that causes mastitis typically come from?

The organism that typically causes mastitis often originates from the mother's skin. Mastitis is an infection that can occur during breastfeeding, and it is usually due to bacteria such as Staphylococcus aureus, which can be present on the skin's surface. When a crack or sore in the nipple allows these bacteria to enter the breast tissue, it can lead to infection and inflammation.

While infants can introduce bacteria from their mouths, the primary source leading to mastitis is more directly linked to skin flora and procedures associated with breastfeeding, rather than being sourced from the infant. The emphasis in understanding mastitis should focus on the mother's skin as a common reservoir for the bacteria involved.
