Background:  Staphylococcus aureus is a Gram-positive bacterium, which can be found on skin and in mucous membranes. This bacterium can cause pneumonia, meningitis and sepsis and is a microorganism responsible for nosocomial infections. Some strains are resistant to antibiotics like methicillin and vancomycin and therefore more difficult to treat. Staphylococcus epidermidis is a Gram-positive bacterium colonizing skin and mucous membranes of humans. It can lead to infections through various implanted medical devices such as joint prostheses, cardiovascular devices or heart valves. Staphylococcus saprophyticus can lead to urinary tract infections, with young women being more severely affected. Other species of staphylococci such as S. lugdunensis, S. haemolyticus, S. warneri, S. schleiferi, S. intermedius are generally non-pathogenic but can lead to infections in rare cases.

Description:  BactoReal® Kit Staphylococcus & S. aureus is a real-time PCR for the qualitative detection of the Staphylococcus aureus (nuc gene) and Staphylococcus spp. (23S rRNA gene). Our carefully designed primers and probe ensure highest sensitivity and specificity. The kit consists of an assay mix for the detection of the pathogen as well as a positive control and an internal positive control (IPC) system. To minimize PCR cross-contamination, the included reaction mix contains dUTP and uracil-N glycosylase (UNG).

PCR platforms: BactoReal® Kit Staphylococcus spp. & S. aureus was validated with the ABI® 7500 Fast Real-Time PCR System (fast cycle parameters are not supported, Thermo Fisher Scientific), and was also tested with Mx3005P® (Agilent), qTOWER3G (Analytik Jena), MIC instrument (bio molecular systems), LightCycler® 480 II (Roche) and cobas Z 480 Analyzer (Roche). It is also compatible with other real-time PCR instruments which detect and differentiate fluorescence in the FAM and Cy5 channel (e.g. QuantStudio 5 / 6 / 7 (Thermo Fisher Scientific)).

Frequently Asked Questions:

The kit detects the 23S rRNA gene of Staphylococcus spp. in the FAM channel and the nuc gene of Staphylococcus aureus in the VIC channel using multiplex real-time PCR.
Staphylococcus aureus is a major pathogen associated with pneumonia, meningitis, bloodstream infections, and sepsis. Some strains are resistant to antibiotics such as methicillin, making rapid molecular detection important for patient management.
Validated specimens include EDTA blood, aspirates, cerebrospinal fluid (CSF), and biopsies.
The kit contains an internal DNA positive control (IPC), added during extraction and detected in the Cy5 channel, which ensures extraction efficiency and excludes PCR inhibition.
The limit of detection (LoD95%) is 8 target copies for Staphylococcus spp. (500 copies with cut-off rule) and 2 target copies for Staphylococcus aureus per reaction.
BactoReal® , MycoReal® , PanReal, ParoReal ® and ViroReal® Kits run with the same thermal cycling conditions.
