DEHYDRATED IMMEDIATE RECONSTRUCTION CULTURE MEDIUM TO IDENTIFY GROUP B STREPTOCOCCI STREPTOCOCCUS AGALACTIAE BY THE DETECTION OF THEIR PIGMENT

摘要

The invention relates to a dehydrated culture medium for detecting Streptococcus agalactiae by their pigment, wherein only water is adde d and the medium is then shaken prior to utilization. Once rehydrated, a semisolid gel is produced which enables growth of S. agalactiae insid e the medium as pigmented colonies thereby facilitating easy detection. The ne w instant reconstruction medium consists of a dehydrated culture medium and a gel-forming agent. When the user adds ambient temperature water and shakes t he medium, a gel is immediately formed and the medium is then ready for utilization. Streptococcus agalactiae grows in the medium as pigmente d colonies thereby enabling easy detection thereof. Once rehydrated, the mediu m has sufficient consistency for the bacterial growth not to form sediments an d solidifies rapidly enough so that air bubbles are trapped when the medium is shaken. Said air bubbles remain inside the medium during the incubation peri od and create interphases activating the production of S. agalactiae pigment producing heavily pigmented colonies.
