title: Mice in the emergency department: vector for infection or technological aid?
abstract: OBJECTIVE
  To study the type of bacterial flora present on computer mice in an emergency department.
  
  
  METHODS
  Computer mice in the emergency department of a single institution, were swabbed on three separate occasions over a 12-month period. Swabs were plated out on McConkey agar and blood agar. Isolated organisms were identified by senior laboratory personnel using Gram stain, colony morphology and susceptibility testing.
  
  
  RESULTS
  No methicillin-resistant Staphylococcus aureus was identified on the equipment. Two samples cultured methicillin-sensitive coagulase positive staphylococci. A range of other organisms were identified.
  
  
  CONCLUSIONS
  In contrast to studies in other hospital departments, no methicillin-resistant Staphylococcus aureus was identified on computer mice in the emergency department. These results suggest that mouse operated software is not adding to infection control problems in relation to methicillin-resistant Staphylococcus aureus in this environment.
