Basics of Medical Microbiology
Clinical microbiology classically focuses on microorganisms that make people sick “pathogens”. Founders of clinical microbiology were Louis Pasteur and Robert Koch. Until the first half of the nineteenth century, cleanliness and disinfection in medicine were not considered necessary, because the causative agents of infection were unknown. However, clinical microbiology was advancing rapidly revealing the pathogens of tuberculosis, diarrhoea, sepsis and many more. Koch and Henle published postulates linked microorganisms with infectious disease.
