How to count a
hemocytometer
The product units: PFUs/mL
Direct Growth
Measurements
Defined vs. Complex In defined all components and amounts are
media known where complex not all quantities are
known and it supports the growth of most
organisms.
Non-selective vs. Selective "selects" for growth but inhibits others, ie
selective media gram positive
Non-differential vs. Differential allows for "differentiation" of
differential microbes on their ability, ie lactose
fermenting
Columbia CNA Agar
MacConkey Agar
Mannitol Salt Agar
Substance that adheres to external surface of
Glycocalyx cells. Made up of sticky polymer ( saccharides
and peptides)/ Helps keep organisms from
drying out and keep nutrients
Capsule Type of glycocalyx that helps protect the cell from the
host immune response.
Biofilms Micro-colonies of bacteria that stick together
with capsules or slime layers that attach to a
surface/ provides from antibiotics, disinfectants,
and immune system
mycolic acid Lipids that resist most staining and they cause
diseases (myobacterium and nocardia)/
