The benefits of chromID Salmonella

 A new principle for easier reading

• Specificity: 3 chromogenic substrates optimize the selective isolation and differentiation of Salmonella, including the serotypes Typhi, Paratyphi and most Lactose positive Salmonella.
• Nutrient capacity:  the rigorous selection of ingredients provides large Salmonella colonies with irregular edges and an intense colouration, after only 18 to 24 hours incubation at 37° C.
• Selectivity: the selective system chosen ensures excellent inhibition of contaminating food flora: Gram-positive cocci, yeasts and the majority of non-fermenting Gram-negative organisms.

 A solution to food industry constraints

• Reliable results: the high level of sensitivity of chromID Salmonella avoids false negative results.
  chromID Salmonella:  100%. Other chromogenic medium: 93%, XLD: 89%
  (Results obtained during an independent expert evaluation on 28 matrices naturally and artificially contaminated and according to the NF EN ISO 6579: 2002 protocol by combining the RVS and MKTTn results) 
• Cost savings: important reduction of confirmation tests due to chromID Salmonella  specificity. 
• Adapted to real conditions of use: chromID Salmonella  was evaluated on a large number of naturally or artificially contaminated food matrices. 
• Adapted to several protocols:
  • Detection of Salmonella in selective enrichment broths: Rappaport Vassiliadis Soy (RVS), Muller Kauffmann with Tetrathionate and novobiocin (MKTTn), Rappaport Vassiliadis (RV) and Selenite Cystine (SC) according to different standardized protocols (e.g., NF EN ISO 6579 : 2002).
  • Detection of Salmonella according to the VIDAS® Immuno-Concentration Salmonella method (VIDAS ICS/plate method)
  • Confirmation of positive VIDAS Salmonella tests (VIDAS SLM)
  • Direct identification of suspect isolated colonies with API® 20 E and ID 32 E strips
