Lab 9 Control Of Microbial Growth

Antibiotic Suceptibility

Disinfectants

Bateriostatic

To measure the relative effective of various disinfectants and antiseptics against bacterial organism

Chemical agents that are used to control microorganism

Producere to ensure accurate and producible results

Agar 0.3 %

Muller- hilton agar which has a spesific ph of 7.2-7.4 unifor depth 4mm

Solid agar

MacFarland 0.5 turbidity aproximately 1.5 x 10^8 power baterial/ml antibiotic discs with a know potency

0.85% turbidity

1.0 5 turbidity

Aspergillus sp., Penicillium sp., or Rhizopus sp.

Serratia marcescens

E.coli , S.Aureus, and P.Aeruginosa

Chemical agents applied to inanimate objects. More harsh. Some may destroy endospores (steriliants or sporocides) (ex – ethylene oxide)

Chemical agents that are used to control microorganisms

(alcohol, betadine) – can be applied to tissue, do not destroy endospores.

Chemical agents that are used to control microorganisms

Agents that reduce microbial growth but do not eliminate all microbes (food industry – used to clean cooking equipment)
