	Sterilization (microbiology) (Site not responding. Last check: 2007-10-26)
		Sterilization (or sterilisation) is the elimination of all transmissible agents (such as bacteria, prions and viruses) from a surface, a piece of equipment, food or biological culture medium.
		Heat sterilization is known to have been in used in Ancient Rome, but it mostly disappeared throughout the Middle Ages where sanitation was not usually a concern.
		It is routinely used to sterilize the interiors of biological safety cabinets between uses, but is ineffective in shaded areas, including areas under dirt (which may become polymerized after prolonged irradiation, so that it is very difficult to remove).

		Indicators should be placed in the most difficult place sterilization is wanted, for instance if you are sterilizing the contents of universals (a universal is a type of small glass jar), the Attest vial should be placed in a universal, to ensure that steam actually penetrates these areas.

	Sterilization (microbiology) Summary
		Steam heat (moist heat) sterilization is performed on a daily basis in the microbiology laboratory.
		Sterilization (or sterilisation) is the elimination of all transmissible agents (such as bacteria, prions and viruses) from a surface, a piece of equipment, food or biological culture medium.
		Gamma rays are very penetrating, but as a result require bulky shielding for the safety of the operators of the gamma irradiation facility; they also require storage of a radioisotope, which continuously emits gamma rays (it cannot be turned off, and therefore always presents a hazard in the area of the facility).

		The Oral Microbiology Laboratory (OML) located at the UNC School of Dentistry provides diagnostic clinical microbiology, microbiological research, microbiology training and sterilization monitoring services to both the School of Dentistry and the community of dental practitioners in the state of North Carolina and surrounding geographic area.
		These services are specifically related to oral microbiology and its application to the following: recognition and assessment of oral bacterial populations in oral flora studies, post treatment of oral infection, bacterial test for caries risk, and the monitoring of sterilization equipment unique to the dental practice.
		The Oral Microbiology Laboratory (OML) accepts oral bacteriological specimens (plaque, surgical, aspirates and saliva) from the clinical departments and from the faculty practice of the school, as well as, from private practitioners in the community for the culture, identification and quantitation of oral pathogens.

	Testing of several methods of sterilization in dental practice
		Sterilized samples including mouth mirrors, probes, excavators and tweezers were collected from the clinics, put in sterile envelopes prepared previously for this purpose and sent immediately to the microbiology laboratory in Queen Alia Military Hospital, Amman, for culturing.
		We may conclude that the performance of dry-heat ovens is acceptable as a method of sterilization but it takes a long time_one hour after reaching 160 øC; another disadvantage is that most dry-heat ovens do not have an uninterrupted cycle, which renders them liable to interruption of sterilization.
		In the second part of the study, 100 dental items were sterilized by chemical means (Savlon hospital concentrate solution; chlorohexidine gluconate 1.5% w/v and cetrimide 15% w/v) with dilution rate 35 ml made up to 1 litre with water (which was not checked for sterility).

	The Control of Microbial Growth (Site not responding. Last check: 2007-10-26)
		Sterilization is the complete destruction or elimination of all viable organisms (in or on an object being sterilized).
		Sterilization procedures involve the use of heat, radiation or chemicals, or physical removal of cells.
		Ultraviolet light is usually used (commonly used to sterilize the surfaces of objects), although x-rays and microwaves are possibly useful.

	Methods Manual – Applied Microbiology
		No untreated surface in the lab is sterile, and nearly all dust and other particles have spores or active cells on their surfaces.
		Sterilization can be accomplished in several ways including the use of moist heat, filtration, ethylene oxide, radiation, or ultraviolet light.
		Use sterile disposable pipets to remove samples from a broth culture that must be kept uncontaminated.

	Features
		Sterilization is usually achieved with the help of heat whereas chemical agents are employed to effect disinfection.
		Sterilization and disinfection are part of the daily routine of microbiological laboratories and constitute a vital activity which ensures that cultures, containers, media and equipment are treated in such a way that only the inoculated organisms will grow while all others will be eliminated.
		Sterilization is an effective method for decontaminating waste, but it does not alter the appearance of the waste.

	Infection Control Manual: Section VIII
		Sterilization unit and clinical dental assisting staff shall monitor the effectiveness of sterilization equipment in accordance with the procedures below.
		Sixty to 90 minutes may be required to sterilize a medium load of lightly wrapped instruments in an oven set at a range of 330 to 345 F. Use paper, foil, or high-temp.
		The only accurate way to calibrate a sterilization cycle in most relatively inexpensive professional medical or professional industrial dry heat ovens is by using an external thermocouple wire attached to a temperature gauge (pyrometer).

		Ethylene oxide (EO) gas is a commonly used sterilization procedure for objects that cannot survive temperatures greater than 60°C. Ethylene oxide treatment is generally carried out at 54–60°C in 60–75% humidity for at least 12 hours.

	Useful information about sterilization and options
		In microbiology, sterilization means the freeing of any object or substance from all life of any kind, this includes spores.
		For microbiological purposes microorganisms may be killed in situ by heat, gases (such as formaldehyde, ethylene oxide, or B-propiolactone), solutions of various chemicals, or ultraviolet or gamma irradiation.
		Sterilization can also be accomplished through mechanical means, such as filtration and centrifugation.

	Micro-Cide 28 HLD
		As with all liquid sterilants, this product should be used for instruments and devices that are heat labile or otherwise incompatible with other methods of biologically monitored sterilization.
		MICROBIOLOGY: Micro-Cide 28 HLD produces high-level disinfection at room temperature (25¡C) in as little time as 25 minutes and complete sterilization in 10 hours at room temperature (25¡C).
		In the absence of a sterilization system, high-level disinfection is appropriate since feeding tubes fall into the FDA classification as "non-critical devices" because they are intended to make contact with mucous membranes and are not intended to enter into the vasculature nor make contact with sterile tissue.

	CHAPTER #1: BRIEF HISTORY OF MICROBIOLOGY
		He reasoned that the microbes in the air that could contaminate the sterile broth would be trapped on the sides of the thin glass necks before they reached the sterile broth.
		This is exactly what happened, the flasks remained sterile indefinitely, until Pasteur tipped the sterile broth up into the curved neck where he predicted the airborne organisms would have settled.
		These include the sterile culture techniques, pure culture techniques, the use of petri plates, inoculation needles, solid medium, the use of agar and gelatin to produce a solid surface, the Gram stain and other staining procedures.
