title: Evaluation of silicon oil on bacterial growth.
abstract: OBJECTIVE
  To analyze the antimicrobial properties of silicon oil (Óleo de Silicone®, Ophthalmos, Brazil) on in vitro bacterial growth of different microorganisms related to endophthalmitis.
  
  
  METHODS
  The following microorganisms were analyzed: (1) Pseudomonas aeruginosa (ATCC 27583); (2) Escherichia coli (ATCC 25922); (3) Staphylococcus aureus (ATCC 25923); (4) Staphylococcus epidermidis (ATCC 12228); (5) Candida albicans (ATCC 10231); (6) Klebsiella pneumoniae (ATCC 13883); and (7) Streptococcus pneumoniae (ATCC 49619). The plates were incubated at 35 ± 2ºC and its growth examined after 24 hours. An empty disk was placed in the center of each plate as a control.
  
  
  RESULTS
  No inhibition halos were verified in any of the plates containing the four different concentrations of the bacterial inocula.
  
  
  CONCLUSIONS
  The silicon oil 1000 cps does not have any effect on bacterial growth of any of the studied microorganisms.
