Resistance of disposable drapes to bacterial penetration.
PURPOSE To test the bacterial penetrability of disposable non-woven drapes used specifically for total hip arthroplasty. METHODS 12 round agar plates were inoculated with 107 colony-forming units/ml of coagulase-negative staphylococci (CNS) and incubated in air at 37 degrees Celsius for 18 hours to obtain a semi-confluent growth of organisms. Six brands of disposable drapes were tested; each ...
متن کاملBacterial biofilm shows persistent resistance to liquid wetting and gas penetration.
Most of the world's bacteria exist in robust, sessile communities known as biofilms, ubiquitously adherent to environmental surfaces from ocean floors to human teeth and notoriously resistant to antimicrobial agents. We report the surprising observation that Bacillus subtilis biofilm colonies and pellicles are extremely nonwetting, greatly surpassing the repellency of Teflon toward water and lo...

متن کاملBacterial contamination of nonsterile disposable gloves before use.
BACKGROUND After Bacillus cereus recovery in opened boxes of disposable gloves, the bacteriological contamination of disposable nonsterile gloves kept stored in native packages was investigated prospectively. METHODS Thirty-six commercially available nonsterile nonpowdered disposable gloves made of latex, vinyl, or nitrile were cultured. RESULTS A large variety of spore-forming and non-spor...
متن کاملDepth-dependent resistance of granular media to vertical penetration.
We measure the quasistatic friction force acting on intruders moving downwards into a granular medium. By utilizing different intruder geometries, we demonstrate that the force acts locally normal to the intruder surface. By altering the hydrostatic loading of grain contacts by a sub-fluidizing airflow through the bed, we demonstrate that the relevant frictional contacts are loaded by gravity r...
