[Comparative study of the effect of various antiseptics and ozone gas on pathogens of ulcus cruris]

The germicidal influence of various antiseptics on the bacterial and fungal flora of leg ulcers was studied in vitro. Best effects were achieved by the triphenylmethane dyes brilliant green and methylrosaniline chloride. Chloramine and povidone iodine yielded average results, whereas the germicidal effects of potassium permanganate and eosin were not satisfactory. On the other hand, treatment with ozone resulted in sufficient inactivation of germs--with the only exceptions of Serratia and Klebsiella species.
