Facultative anaerobe |
Does not require oxygen can grow with or without it. Able to detoxify toxic byproducts of oxygen Growth throughout test tube Example: E.Coli |
|
|
Microaerophile |
Does not grow an atmospheric oxygen but requires a small amount for growth. Detoxifies toxic byproducts of oxygen
Grows in the middle of the tube
Example: micrococcus luteus |
|
|
Anaerobe |
Lacks the enzyme for using oxygen can't live in oxygen. Not able to detoxify toxic byproducts of oxygen Gross at the bottom of tube Example; clostridium |
|
|
Anaerobic jar |
Remove O2 increase CO2 concentration BD GasPak contain inorganic carbonate Turns blue in presence of O2 and colorless in presence of CO2 |
|
|
Fastidious bacteria |
Excessively particular, critical, or demanding |
|
|
Fluid thioglycollate medium |
Used for aerobic, anaerobic, fastidious and non fastidious organisms |
|
|
Enterics |
Rod-shaped, Gram-negative, gut bacteria. Most occur normally or pathogenically in intestines |
|
|
Enteric plates |
Selective media for isolation of gram-negative bacteria Example: Eosin Methylene Blue Agar |
|
|
Coliforms non-pathogenic bacteria |
Rod-shaped, Gram-negative, non-spore forming bacteria which can ferment lactose with the production of acid and gas at 35-37C Example, E. Coli, Enterobacter aerogenes |
|
|
Opportunistic pathogens |
Proteus mirabilis Only when immune system is weak |
|
|
True pathogens |
Salmonella spp, and Shigella spp Pathogens that causes disease in virtually any susceptible host |
|
|
Eosin methylene blue agar(EMB) |
Used in isolation of gram-negative bacteria E-coli-green metallic Sheen, strong lactose or sucrose fermenter Enterobacter-pink, slow lactose fermenter and little acid producer |
|
|
Hektoen enteric agar (HE or HEK) |
Uses bile salts to inhibit growth of gram+ bacteria Shigella, salmonella and proteus (bluish green colonies, sugar non fermenter) Salmonella and Proteus have colonies with black precipitate (reduce sulfur to H2S) Shigella no black precipitate E-coli, enterobacter (yellow to pink colonies) |
|
|
Enterotube |
Has 12 compartments and 15 tests |
