Thermo Scientific™ Biocemical Identification System (O.B.I.S.) PYR

Description

• Rapidly determine PYRase activity is streptococci and Citrobacter spp
• with Thermo Scientific™ Oxoid™ Biochemical Identification System (O.B.I.S.) PYR
• This rapid colorimetric test delivers simple and rapid results for the determination of PYRase activity in streptococci and Citrobacter spp, offering a rapid diagnostic alternative to time-consuming culture methods
• In addition, the same enzymatic activity may be used to aid differentiation of Salmonella spp
• from Citrobacter spp and other Enterobacteriaceae 1,2
• Use O.B.I.S
• PYR as a rapid diagnostic alternative to time-consuming culture methods
• Simple—easy to implement Rapid—results in 6 minutes of testing suspect colonies Non-carcinogenic substrates The O.B.I.S
• - PYR test uses Test Cards impregnated with L-pyroglutamic acid 7-amino-4-methyl-coumarin (7AMC) and dimethylaminocinnamaldehyde for the detection of PYRase activity
• The enzymatic hydrolysis of this substrate by enterococci, Group A streptococci and Citrobacter spp
• produces a purple color following the addition of the Developing Solution 3
• We have developed a new system for PYRase testing 4 using a non-carcinogenic substrate in response to health concerns associated with the use of β-naphthylamide (a potent carcinogen) 5
• The PYRase area on the O.B.I.S
• PYR test is impregnated with L-pyroglutamic acid 7-amino-4-methylcoumarin (7AMC) 4
• Dimethylaminocinnamaldehyde is used as a color development reagent
• The enzymatic hydrolysis of the substrate produces a purple color on addition of the O.B.I.S
• PYR Developing Solution 4
