  • Patent number: 5897993
    Abstract: A method of determining the number of bacteria in a sample which involves introducing a sample containing bacteria into a tubular filtering vessel holding therein a hydrophobic filter for bacterial detection, a coloring composition is disposed on the side of the filter where the sample is introduced into the vessel, and a support for the filter is disposed on the opposite side of the filter from the coloring composition. The bacteria is subjected to and the sample is filtered dyeing sample by suction from the support to collect the dyed bacteria on the filter and remove the excess of coloring matter.
