The device for spraying a reagent onto a support () adapted to retain microorganisms on a predetermined surface (), comprises a spraying bell () as well as a nozzle () for emitting a jet of droplets of said reagent into a spraying chamber () comprised by said bell (), said device also comprising an absorbent pad () mounted against said bell () transversely to said jet and closing said chamber () from the opposite side to said nozzle () with the exception of a circular central opening () provided in said pad (), the diameter of said central opening () being adapted to enable a portion of said jet, when said device faces said support () and is at a predetermined distance therefrom, to pass through said central opening () over its entire area and be deposited on the whole of said predetermined surface () of said support ().

Device for spraying a reagent for fast microbiological analysis

Device for spraying a reagent onto a support adapted to retain microorganisms on a predetermined surface. The device includes a spraying bell as well as a nozzle for emitting a jet of droplets of the reagent into a spraying chamber comprised by the bell, the device also including an absorbent pad mounted against the bell transversely to the jet and closing the chamber from the opposite side to the nozzle with the exception of a circular central opening provided in the pad, the diameter of the central opening being adapted to enable a portion of the jet, when the device faces the support and is at a predetermined distance therefrom, to pass through the central opening over its entire area and be deposited on the whole of the predetermined surface of the support.

The present invention relates to a composition for the permeabilization of the walls of microorganisms comprising the combination of octyl-&#x3b2;-D-glucopyranoside (NOG), sodium polyphosphates (HMP), and a salt chosen from lithium chloride or rubidium chloride, and a method for the enumeration and identification of cells on a membrane using said composition.
