| Abstract: | The incidence of and nature of fingernail flora was studied in 20 patients. These patients underwent routine preoperative hand scrubbing in a clinical setting, without nail trimming or cleaning. Nineteen (95%) of 20 had a moderate to heavy growth of Staphylococcus epidermidis. These isolates were very susceptible to antibiotics. Thirteen (65%) of 20 patients had fungi (molds and yeast). In spite of adequate preoperative hand scrubbing, the fingernails were heavily contaminated. Such organisms may become pathogens and should not always be considered contaminants. This study also confirmed the importance of preoperative fingernail trimming and cleaning. |
