Asepsis secundum artem : the practical application of the art of asepsis to the preparation of surgical dressings . 14 Bacteriological Tests^. THE products of our aseptic laboratories are subjected to bacte-riological tests to check efficiency of sterilization processes, theprocedure being substantially the following :— A portion of the dressing material (for example, a piece ofgauze) is impregnatedwith an infected nutrient fluid. Thethus infectedmaterial is thendried in air. Asa check experi-ment, a portionof this nfectedand dried ma-terial is placedin sterilized nu-trient jelly inthe culture

Theremaining portion of the infected material is then passed through the steriliza-tion process, care being taken that it passes throughlike conditions as would the sterilized dressings. After a suitable time (at least three days), ifa growth is found in the check experiment, we arecertain that the test material was infected. If nogrowth has taken place in the infected material thathas passed through the sterilization processes, weare certain that sterilization has been complete inall the dressings.
