MicrogenTM Staph-ID has been developed for the identification of commonly encountered Staphylococcus spp. Isolated from clinical and veterinary samples. These bacteria, although commensal, are recognised as potential human pathogens e.g. S. aureus and S. epidermidis. Coagulase negative Staphylococcus spp. Are common colonisers of prosthetic valves and in-dwelling catheters.
Gram stain (positive), catalase (positive) and latex agglutination / coagulase tests are performed as pre-tests on the isolate. Colony pigmentation is recorded and then 1-2 colonies are inoculated into the suspending medium. The suspension is inoculated into the 12 well test strip and incubated at 37°C. After 24 hours incubation the strips are read and the Nitrate and PYR reagents added. The resulting 5 digit numerical code is entered in to the software to generate an identification.
