Abstract
   The objective of this paper was to determine the bactericidal activity of CID 20 decontaminant on a strain of Staphylococcus aureus, ATCC 25923.
   To achieve this goal, the following work plan was prepared: Artificial contamination of 100 cm2 surfaces was made using an aluminum template with 10 x 10 cm sides; 1 bacterial strain of Staphylococcus aureus ATCC 25923 was used to prepare a bacterial suspension with a 1 McFarland density using a Biosan density.
   From the 1 McFarland density bacterial suspension, several work solutions with different concentrations of 0.25%, 0.5%, 1% were made.
   Several surfaces were contaminated with the Staphylococcus aureus suspension ATCC 25923, then these surfaces were sprayed with the CID-20 decontaminant and, finally, sanitation tests were taken to verify the effectiveness of the decontamination with this product.
   The conclusion of our research was that decontaminant CID 20 with a concentration of 0.25% has an effective action on bacteria of the Staphylococcus genus but only when the contact time is prolonged to at least 20 d/min.

Key words: decontaminants, bacterial suspension, bacteria of the Staphylococcus genus
