8And be added in the 9ml tryptose soya agar aliquots containig (500 μ l) of each suspension and soft the mixing cfu/ml).The aliquots containig (100 μ l) of described bacterial suspension is placed on each slide glass and with pipette tip cultivation liquid is extended to the edge.Then pallet is placed in the big sterile bag (unsealing) and puts into 37 ℃ incubator and spend the night.Inoculated slide glass with fresh bacterial suspension in second day and be back in the incubator.
Handle
Rare test soln (3ml) is placed in the hole of 12 hole MTP, in room temperature slide glass is vertically put into test soln 30 minutes (not stirring).Shift out slide glass and use wash bottle with SDW rinsing gently.Then wave carrier piece is kept flat and also cultivate (37 ℃) on the pallet to dry.Ethanol (70%) is sprayed onto wants on the fixed slide glass, then with the crystal violet solution slide glass that dyes.Use the x100 oil immersion lens to obtain presentation graphics (Fig. 3).
Image is carried out rough quantitative analysis as the method for calculating bacterium surface covering level.This is undertaken by open each image and gray scale demarcation (greyscaling) this image in Irfan View.Select enhancing color options and corresponding ratings to slide to the rightmost side (maximum) then.This generates the image that is made of the black and white pixel.In PaintShop Pro, open described image then and select the histogram option.This makes it possible to the per-cent on each image " darkness " is measured, and bacterium covered level after its representative was handled.Referring to Fig. 4 and following table 1.
Table 1: darkness (%) level of distributing to each image
