Final answer:
Lactational mastitis is primarily caused by Staphylococcus aureus and sometimes by Streptococcus species. It is a painful condition for breastfeeding women, requiring prompt treatment to prevent complications.
Step-by-step explanation:
The most common organisms associated with lactational mastitis are Staphylococcus aureus and, less frequently, Streptococcus species. These bacteria can lead to infections that, if untreated, may progress to more serious conditions. Particularly, Staphylococcus aureus is known to be a primary cause of mastitis in breastfeeding women, often resulting from skin-to-skin contact or contaminated surfaces.
Lactational mastitis is a painful condition affecting breastfeeding women and is characterized by inflamed breast tissue which can become infected by different pathogens. Immediate medical attention is required for treatment with appropriate antibiotics to prevent the infection from worsening.
