Shimadzu Diagnostics Compact Dry SL [Salmonella] | Code 54058

Compact Dry is ready to use and portable plate containing dried sheet medium. Detach necessary number of plate from a set of four by bending up and down while pressing the lid. It is available for solid food staff (homogenize with buffer solution), water or liquid sample and swab test.Drop 0.1mL of enriched specimen at approx. 1 cm from the edge of plate gently. After inoculating the specimen, drop 1mL of sterilized water at the opposite point where specimen dropped. Water shall diffuse automatically.Inoculated sample diffuses automatically and evenly into the plate (dried sheet medium is transforming to gel form).Specimen should be diluted by buffer solution to the level of concentration of less than 300 cfu/plate. If bacteria more than 104 cfu were inoculated on a plate, no colonies are formed, and no colored colonies eventually are appeared on the plate but all plate sheets become seemingly colored.Put the cap again immediately after inoculation. Incubate at 41 - 43°C for 20 - 24 hours.Interpretations
 Black to Green isolated or fused colonies are observed, and sheet around the colonies is changed to Yellow If a large quantity of Salmonella is inoculated on a plate, no isolated colonies are formed (there may be several spots with fused Black or Green colonies), but whole plate sheets become seemingly Yellow.There is no color change occurred on the sheet. If it were occurred, the sheet color would be changed to Red or Reddish purple. No Black or Green colonies are observed.
The sheet color might be changed to Yellow caused by Pseudomonas or Proteus. But Yellow portion is small and limited because of their less motility.
