Iodophors as disinfectants.

Comparative tests were made of the bactericidal and fungicidal activities of an iodophor (Wescodyne®), Roccal®, Amphyl®, and phenol. Roccal was the only germicide in the group that was adversely affected by a synthetic hard water solution. With the exception of phenol, the remaining germicides showed some loss in bactericidal activity when examined in the presence of serum. Wescodyne was found to be highly fungicidal and distinctly lethal for tubercle bacilli. The same compound was also effective in moderate concentrations against spores of B. subtilis
