Lactation mastitis: bacterial cultivation of breast milk, symptoms, treatment, and outcome

Abstract

The aim of this prospective study was to compare serum C-reactive protein (CRP) and leukocytes, hemoglobin, clinical signs, treatment, and outcome among 41 episodes of lactation mastitis grouped by the outcome of bacterial cultivation of breast milk. Group A included 25 cases with positive cultures only for bacteria normally present on skin. Group B included 16 cases in which cultures indicated the presence of potentially pathogenic bacteria. Serious complications were observed among women in group B, including protracted illness and weaning. No complications were observed in group A. Staphylococcus aureus was the most frequently isolated bacteria in group B. Mean serum leukocytes were significantly higher in group B than in group A. Although CRP levels in both groups were elevated, no significant difference was found between groups. Rest and frequent emptying of the breast were curative in group A. Further interventions were necessary for mothers in group B.
