Bioburden testing for medical devices made or used in the USA is governed by Title 21 of the Code of Federal Regulations and worldwide by ISO 11737. The aim of bioburden testing is to measure the total number of viable micro-organisms (total microbial count) on a medical device prior to its final sterilization before implantation or use. [2]
for human anatomical, animal, microbiological and soiled waste •Red disinfected container or plastic bags: microbiological waste, solid waste(IV tubes, catheters, etc.) •Blue or White plastic bag or puncture proof containers: sharps, disposable tubing, etc. •Black Plastic bag or puncture proof containers
Microbial inactivation of G. stearothermophilus with NO 2 gas proceeds rapidly in a log-linear fashion, as is typical of other sterilization processes. Noxilizer, Inc. has commercialized this technology to offer contract sterilization services for medical devices at its Baltimore, Maryland (USA) facility. [38]
Medical microbiology, the large subset of microbiology that is applied to medicine, is a branch of medical science concerned with the prevention, diagnosis and treatment of infectious diseases. In addition, this field of science studies various clinical applications of microbes for the improvement of health.
These chains are anchored to the device surface by covalent bonds, producing non-leaching, contact-killing surfaces. One in vitro study found that when N-alkylpyridinium bromide, an antimicrobial agent, was attached to a poly(4-vinyl-N-hexylpyridine), the polymer was capable of inactivating ≥ 99% of Staphylococcus epidermidis , Escherichia ...
A biosafety cabinet (BSC)—also called a biological safety cabinet or microbiological safety cabinet—is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with (or potentially contaminated with) pathogens requiring a defined biosafety level.
McCartney's bottle or Flat medical bottle: for simultaneous solid and liquid cultures. McIntosh and Filde's anaerobic jar: production of anaerobic conditions for organisms that die in the presence of even little oxygen (anaerobiosis), e.g. tetanus bacteria Microscope: to observe microscopic specimens that cannot be seen by the naked eye ...
Today, guiding publications for biosafety and containment in the US are set by the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH). [10] Since 1984, the CDC and the NIH have jointly authored the Biosafety in Microbiological and Medical Laboratories (BMBL).
