BIOBURDEN ON SURGICAL INSTRUMENTS
-
Bioburden refers to the population of viable micro-organisms contaminating an object, although it is also often used to describe residual organic material (protein etc.) on surgical instruments.⁵
-
Inorganic and organic materials interfere with the efectiveness (i.e. antimicrobial activity) of disinfectants and sterilization.²
BIOBURDEN & BIOFILMS IN BRIEF
-
Biofilm is an aggravating factor in bioburden removal strategies as 99% of bacteria exist in the form of a biofilm.⁶
-
Biofilms form a protective barrier around infectious micro-organisms and often form on medical devices.
-
Biofilms and bioburden, including protein soiling, must be eliminated to ensure disinfection and sterilization.
-
Biofilms enhance survival of exposure to antimicrobials due to structural and functional properties of biofilm matrix.
-
Bacteria are up to 1000x more tolerant to biocides when in a biofilm. ⁷
