An attempt at bacterial examination of contaminated surfaces such as preaseptic medical materials is described : Specimens are immersed in culture-broth, then are subjected to official incubation for 7 days at 31℃ (for bacterium), and 10 days at room temperatures (for fungus), respectively. The most probable number of microorganisms is calculated from the frequency of clouded tubes, similarly as MPN techniques (multiple fermentation tubes method) for the estimation of coliform density in water. None of procedures with agar-stamps, agar sausages, and membrane filters are reliable, because of uncertain migration to agar, or meager multiplication on filters. By the proposed method, a count of 11 per 100 cm^2 was estimated on preaseptic specimens of the previously described rubber-like poly (vinyl alcohl) membrane.
