Abstract: Objective To investigate association between Staphylococcus spp. including species and the clinical features of lactational mastitis. Methods From June 2016 to May 2017, 63 patients with lactational mastitis in Department of Breast Shuguang Hospital Affiliated to Shanghai Traditional Chinese Medicine University were included in this study. A total of 126 milk samples were collected from bilateral breast of the patients for bacterial culture of milk. Correlation between Staphylococcus and clinical features was studied using Spearman correlation and association rule analysis with Apriori algorithm. Results The correlation was present between the results of bacterial culture of milk and clinical feature of the patients with lactational mastitis. The clinical features were related to Staphylococcus spp, or Staphylococcus aureus, but not to Staphylococcus epidermidis or Staphylococcus lentus. Only negative result of bacterial culture of milk was associated to the features such as VAS score of breast pain, redness and swelling, tenderness. However, the support degree of association of negative bacterial milk was lower than that of association of Staphylococcus. Conclusions Bacterial culture of milk should be the effective approach to diagnose lactational mastitis. The correlation between Staphylococcus spp. and clinical features of lactational mastitis might be based on the different pathogenicity of genus.
