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.

Growth of potentially pathogenic bacteria such as β-hemolytic streptococci or Staphylococcus aureus in breast milk cultures is associated with longer time to recovery and more frequent abscess formation.
“Although breast milk cultures are not routine in PPM management, the growth of potentially pathogenic bacteria (such as β-hemolytic streptococci or Staphylococcus aureus) is associated with longer time to recovery and more frequent abscess formation (3).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
