Background: Resistance against antibiotics is a global problem that can lead to serious complications. Many bacteria have developed resistance against several antibiotics which causes infections that are hard to treat. Resistant bacteria such as Methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-resistant Enterococcus (VRE) are mainly spread within healthcare. To combat these infections, it is important to have reliable detection methods. Purpose: To qualitatively compare the Copan Transsystem 114c with theESwab-system for the detection of MRSA and VRE. Methods: For the study, Polymerase chain reaction (PCR) methods, Matrix-assisted laser desorption/ionization Time of Flight (Maldi-Tof), and microbiological cultivation methods was used on simulated and clinical samples. Results: For the VRE-samples no difference in results were identified. The MRSA samples showed significant differences in PCR-results where the Transsystem 114c detected 16/60 positive samples whereas the ESwab-system detected 12/60. But the cultivation results showed opposite results where the Transsystem 114c detected three positive samples and the ESwab-system detected four. Conclusion: The results show that both the Transsystem 114c and ESwab show similar results on simulated samples but differ on clinical samples. Further comparative tests need to be carried out to validate the methods before they can be used in routine operation thus no real conclusion can be drawn from this study.
