A low cost innovative enumeration technique that allows rapid monitoring of
low bacterial concentrations is described in this paper. This technique ut
ilizes immuno-magnetic separation methods in combination with ferrographic
methods to deposit magnetic beads and attached bacteria in an exceedingly s
mall area (0.011 cm(2)) on a glass substratum. The bacteria are then enumer
ated under an epifluorescent microscope. (C) 1999 Elsevier Science B.V. All
