Micro FINAL Personal Hygiene Sterilization: removal or destruction of all microbes, including viruses and bacterial endospores in an object. Harmful microbes are gone but some innoculous microbes may still be present Aseptic: an environment or procedure that is free of contamination by pathogens Disinfection: use of physical or chemical agents to inhibit or destroy microorganisms esp. pathogens. Does not guarantee elimination of all pathogens, used only on inanimate objects Antisepsis: when a chemical is used on skin or other tissue Degerming: the removal of microbes from a surface by scrubbing Sanitization: process of disinfecting plates and utensils used by the public to reduce the number of pathogenic microbes so as to meet acceptable public health standards Pasteurization: the use of heat to kill pathogens and reduce the # of spoilage microorganisms in food and beverages How Soap Works A soap is a lipid, with a hydrophilic head and hydrophobic tails. In the presence of H2O, the hydrophobic non-polar tails attach to the dirt, the parts of the soap are surrounding the dirt forming a mycelle. The water falls off the skin and the dirt falls with it. PATHOGENS Gram + Cocci Staphylococcus aureus o Infections in the skin o Capable of growing on the skin because salt tolerant Meningitis Scalded Skin Syndrome Toxic Shock Syndrome Gram + Bacteria Cocci in CHAINS Streptococcus Pyogens o M protein is a cytoplasmic membrane component that destabilizes complement and interferes with phagocytosis and lysis of the bacterium o Pyrogenic 12 toxins (formerly called erythrogenic 13 toxins ) are proteins that stimulate macrophages and helper T lymphocytes to release cytokines that in turn stimulate fever, a widespread rash, and shock. Impetigo Rheumatic Fever Scarlet Fever Streptococcus Pneumonia o surrounded by a polysaccharide capsule, which protects them from digestion after phagocytosis o IgA protease destroys immunoglobulin A and pneumolysin= suppresses the digestion of phagocytized bacteria by interfering with the action of lysosomes Meningitis Gram + Bacilli Clostridium Tetani o obligate anaerobe that produces a terminal endospore TSS Clostridium SPP o Anaerobe o Spore former Blood Borne Viruses

GENERAL SYMPTOMS: Jaundice, fatigue, abdominal pain, loss of appetite, nausea, and diarrhea Hepatitis A Hepatitis A virus can survive on surfaces such as countertops and cutting boards for days, resists common household disinfectants such as chlorine bleach, and is transmitted in fecally contaminated food or water. Patients release virions in their feces and are infective even without developing symptoms. Hepatitis A, also called infectious hepatitis, is typically a mild condition with 99% of patients recovering fully Entry: ingestion via oral or fecal route fever Hepatitis B Entry: blood and fluid transmission Vomiting and joint pain Hepatitis C Transmitted sexually and via contaminated needles. Over 80% of infected people remain
