A note on the use of 3-section plates for the estimation of the numbers of bacteria and to obtain isolated colonies in 1 day.
By streaking with an open loop and then swabbing a 4-5 cm2 area on 3-section agar plates, it is possible to obtain isolated colonies and to estimate bacterial densities from 100 to 10(7)/ml on the swabbed area.
