Dr Sanmarié Schlebusch is Director of Microbiology at Mater Pathology. Dr Schlebusch obtained her MBChB from the University of Pretoria in South Africa. After moving to Australia in 2002 she initially worked as a general practitioner before specialising in microbiology and obtaining her FRCPA in 2009. She has worked in both private and public pathology before joining Mater Pathology in 2010.

Dr Schlebusch has a keen interest in modern technologies for diagnosis of infectious diseases and antimicrobial resistance. She has performed research on staphylococcal toxic shock and developed a PCR to detect the toxic shock gene in S. aureus and she has been the first microbiologist in Queensland to publish on the use of MALDI-TOF-MS. MALDI-TOF-MS (matrix assisted laser desorption/ionisation time-of-flight mass spectrometry) is contemporary technology which can identify micro-organisms within minutes and has been introduced at Mater Pathology.

Dr Schlebusch has presented and published on the application and utility of MALDI-TOF MS including for rapid identification of multiresistant gram-negative bacteria such as Burkholderia cepacia from patients with cystic fibrosis and vancomycin resistant enterococci, as well as for the investigation of outbreaks of MRSA and VRE. She has also presented and published on the use of whole genome sequencing in the routine diagnostic laboratory for determining bacterial relatedness. She is currently undertaking research assessing the effects of antibiotic choice on gut microbiome using a metagenomic sequencing approach.
