In restaurant operations, steriliza tion of dishes is an additional requirement (see STERILIZATION TECHNIQUES). Steriliza tion is deterrnined by the usual swabbing and culturing methods or by employing bacteria tagged with radioactive phosphoms and counting residual radioactivity on the washed dishes (108). 

After washing with chlorhexidine skin cleanser for 15 seconds, a 99.9% reduction of transient contaminants was achieved (216). Chlorhexidine is sometimes combined with alcohol to achieve the rapid reduction obtained with alcohol and the residual effect of chlorhexidine. It is substantive to the skin, and repeated use results in lower levels of bacteria on the skin. 

Topical antiseptics and germicides are primarily used to reduce the number of bacteria on skin surfaces. Some of these drag s, such as chlorhexidine gluconate, may be used as a surgical scrub, as a preoperative skin cleanser, for washing the hands before and after caring for patients, and in the home to cleanse the skin. Others may be applied to minor cuts and abrasions to prevent infection. Some of these drag s may also be used on mucous membranes. 

Goldenseal Hydrastis canadens s Antiseptic for skin (topical), astringent for mucous membranes (mouthwash), wash for inflamed eyes, sinus infections, peptic ulcers, colitis, gastritis Large doses may cause dry or irritated mucous membranes and injury to the gastrointestinal system may reduce the beneficial bacteria in the intestines. Siould not be taken for more than 3-7 days. 

The mixed solution obtained was then placed in a syringe and allowed to drop into a sterile 0.2M CaCli solution that was stirred continuously. Alginate drops solidified upon contact with CaCh, forming beads and thus entrapping bacteria cells. The beads were allowed to harden for 30 minutes at 37 C and then washed with sterile saline solution to remove excess calcium ions and untrapped cells. 

In healthy individuals, the bladder, ureters and urethra are sterile and sterile urine constantly flushes the urinary traet. Organisms invading the urinary traet must avoid being detached Ifom the epithelial surfaces and washed out during urination. In the male, since the urethra is long ica. 20 cm), bacteria must be introduced directly into the bladder, possibly through eatheterization. In the female, the urethra is much shorter... 

One of the uses of mains water is for washing chemicals used in pharmaceutical preparations to remove impurities or imwanted by-products of a reaction, and although the bacterial count of the water may be low, the volume used is large and the material being washed may be exposed to a considerable number of bacteria. 

Organisms or other biological materials that might be harmful to humans bacteria, fungi, blood, unpreserved tissues, plant materials Avoid skin contact with these materials. Wear mask or gloves. Notify your teacher if you suspect contact with material. Wash hands thoroughly. 

The same principle is used for face washes using Myavert C to cleanse the face of bacteria, without the stinging associated with other forms of anti-bacterial face wash. 

To clarify the nature and activity of these toxins, rhizome exudates (washings), compounds isolated from rhizomes (dhurrin, taxiphyllin, p-hydroxybenzaldehyde), and structurally similar compounds were tested against radish and tomato root growth and growth of nine species of bacteria. Figures 4 and 5 show the results of the radish and tomato bioassay of pure compounds. Dhurrin and toxiphyllin showed little activity in these assays, whereas j>-hydroxybenzaldehyde was active in the radish bioassay.

DNA,83 which produces one million or more copies of amplified DNA in a short time. For identification of bacteria, PCR can be used to amplify DNA either after extraction from a sample or after lysis of the cells.83,84 Methods using washing, filtration, or magnetic beads with specific antibodies can be used to collect bacterial cells for PCR.85,86 PCR can be modified for the detection of bacteria from various sources32 and can even amplify DNA from dead cells.87...
