Method uses bacterial culture plates of dry medium and cold water-soluble gel. Undiluted or diluted test suspensions are added to plates at a volume of 1.0 mL per plate. Pressure, when applied to plastic spreader placed on overlay lm, spreads the suspension evenly over a 20 cm growth area. Gelling agent is allowed to solidify, and plates are incubated and then counted. A serological pipet or automatic pipet can be used for suspension addition for bacterial count analysis.
