Normal flora is initially beneficial for their host, but what was once part of the normal flora can later become dangerous to their host, e.g become the agent of endogenous disease. The knowledge regarding normal flora is important for medical students, because it related with many aspects of their recent and future education and trainings, especially in the clinical phase. The aim of this simple cross sectional, questionnaire based study is to measure the level of knowledge regarding normal flora. Study Design: Cross sectional, electronic questionnaire-based survey Place and Duration of Study: Faculty of Medicine, Universitas Kristen Indonesia, Jakarta, Indonesia and conducted for 1 month (March 2021).
