agents
microbial growth agents
Common halogen disinfectant & effectiveness? | Bleach & only fair against endospores |
Iodine is what kind of agent & its effectiveness? | oxidizing agent & poor against endospores & targets bacterial proteins |
Tincture of iodine | likely to irritate skin, prone to staining & used in emergencies for water |
Iodophors | less irritating, not much staining & used to prepare skin for surgery (antiseptic) |
What is Phenol & its effectiveness? | carbolic acid & poor against endospores & targets bacterial proteins and bacterial membranes |
Phenolics? | targets bacterial proteins and membranes, poor against endospores |
bisphenols? | 2 phenolic groups & targets bacterial membranes & poor against endospores and mycobacteria |
Bisguanides? | targets bacterial membranes & not effective against endospores |
common bisguanide? | chlorhexidine |
Alcohols? | targets bacterial proteins and bacterial membranes & ineffective against endospores |
Heavy metals have what and target what & effectiveness? | oligodynamic action meaning it has minute quantities & targets bacterial proteins & isn't effective against endospores |
What are Surfactants & what do they target? | surface active agents like soaps and detergents & target bacterial membranes |
Common cationic detergents & effectiveness? | quaternary & ammonium compounds (quats) & ineffective against endospores |
Aldehydes & effectiveness? | EFFECTIVE against endospores & targets proteins and nucleic acids |
Glutaraldehyde | more effective, less irritating compared to formaldehyde |
peroxygens | targets bacterial proteins & strong oxidizing agent |
hydrogen peroxide exception as sterilant? | yes at high concentration can be sporicidal |
Ethylene oxide & effectiveness? | targets proteins and nucleic acids & effective against microbes and endospores |
