title: Microbial growth on agar surfaces studied by incident light differential interference contrast microscopy.
abstract: Microbial surface growth on routine opaque agar media was examined by various incident light microscopical techniques. Only differential interference contrast regularly gave good resolution and contrast. The arrangement of units approaching the size of individual bacteria may be judged by low power dry objectives.
