[Method of determining the antibiotic sensitivity of anaerobic microorganisms using standard disks].
Three variants of the procedure for determination of antibiotic sensitivity in anaerobic microorganisms with the use of standard paper discs were developed. According to the first variant the solid nutrient medium is melted at 46 degrees C and mixed with the culture of the microbe being tested. The mixture is added to the cover of a Petri dish. When the medium becomes solid, antibiotic sensitivity discs are placed onto the agar surface. After that one more layer of the medium is added. The medium is allowed to solidify and some more medium is poured near the cover edge. Immediately after that the Petri dish is placed with its flat surface onto the agar layer in its cover. According to the first and second variants the mixture of the medium and culture is added to a Petri dish and immediately a transparent gas-proof polymer film of the dish size is placed onto the agar surface. Previously antibiotic paper discs or solutions are fixed on the films. THe incubation temperature for all three variants is 37 degrees C. The procedure allows one to observe the culture growth and to obtain the results earlier than in case the culture is incubated in an aerostate. The procedure is simple and saves labor and time.
