Weck Laboratories, Inc. now offers the identification of positive results from testing for the Coliform group of bacteria.  We employ the API 20 E® standardized identification system from bioMérieux.  The system is applicable for Enterobacteriaceae and other non-fastidious, gram negative rods and uses miniaturized biochemical tests and a database.  The test strip consists of microtubes containing dehydrated substrates. These tubes are inoculated with a bacterial suspension that reconstitutes the media.  During incubation, metabolism produces color changes that are either spontaneous or revealed by the addition of reagents.  The reactions are recorded and compared to an Analytical Profile Index table.  The assignment of identification is simple, rapid and reliable.  Transfer, inoculation, enrichment, segregation & identification takes 3 days from the positive coliform result.  It cannot be used to identify any other family of microorganisms or to exclude their presence.  Water treatment and distribution system customers can use this information to track the type of contamination in their systems and take appropriate corrective actions.
