Coliform - Answer-rapidly ferment lactose, are part of normal microbiota, may be opportunistic, aerobic or facultatively anaerobic. Found in soil and plants. Presence in water= impure water and poor sewage treatment 3 types of antigens used to serotype enteric bacteria - Answer-O-outer membrane K- capsular antigen H- flagellar lancefield typing - Answer-grouping catalase negative and coagulase negative bacteria based on carbohydrate composition of bacterial antigens found on cell walls. U...

Obligate halophiles - High osmotic pressure aka lots of salt like the great salt lake Facultative halophiles - Type that causes acne can be in salty also known as osmolaric but not nessesary Neutrophiles - Most bacteria Protozoa and pathogens like neutral ph rang 6.5-7.5 Acidophiles - Really acidic as low as 0 pH Alkalineophiles - Grow best in basic range up to 11.5 ex cholera Thermophiles - Higher temperatures above 45C ex hot springs Hyperthermophiles - Hottest 80C and above Mesophiles...

Disinfection - destruction of vegetative pathogens; usually on inanimate objects. Antiseptic - agent which prevents bact. contamination and growth; usually on living tissue. Which agent doesn't necessarily work better at higher concentrations? - Alcohol, 70% (goldie lock zone)(60-80% most effective) (Ethyl and Isopropyl) -Alcohol is very effective to resistant to inactivation by organic materials (halogens are not good at this) Name the factors that affect a disinfectant activity. ...
