Dr. Katherine Drennan

Katherine Drennan is a clinician-researcher associated with Wits Donald Gordon Medical Centre in Johannesburg, South Africa, with expertise in infectious diseases and gastroenterology. Her work is situated within hospital-based clinical practice, contributing to infection prevention and control initiatives in a tertiary healthcare setting.

Her research focuses on recurrent Clostridium difficile–associated diarrhoea and the clinical application of faecal microbiota transplant. Through retrospective clinical analysis, she has examined patient risk factors, treatment pathways, and procedural safety, particularly the outpatient and nasogastric administration of donor stool.

This body of work highlights strengths in translational, practice-oriented research aimed at improving patient outcomes and informing local guidelines. Based on the limited available publications at present, her contributions emphasize evidence-based antimicrobial stewardship and the safe implementation of emerging therapies in South African clinical contexts.
