Document Summary

Disinfection: liquids kill bacteria eg. phenol based, too toxic for skin uv light, heat, alcohol, bleach: uv light: used on surfaces (ie. ors) not usually effective. Bacteriocidal antibiotics: irreversible drug affected microbes are dead. Treatment by both is sufficient if host defense mechanisms can take care of residual cells. Antibiotics work together with the immune system. Selective drugs that cause: no (or limited) harm to pt (cid:1452) they destroy structures present in bacteria but not in host the(cid:455) destro(cid:455) the (cid:272)ell (cid:449)all for e(cid:454)a(cid:373)ple (cid:271)e(cid:272)ause (cid:449)e do(cid:374)"t ha(cid:448)e a (cid:272)ell (cid:449)all.
