🕰 1. Historical Foundations
🌫 Old Beliefs
Miasma = disease from bad air
Contagion = disease spreads through contact
Important Scientists
🩶 Robert Hooke — coined the term cell
🩶 Anton van Leeuwenhoek — first to observe microorganisms
🩶 Ignaz Semmelweis — handwashing reduced childbirth infections
🩶 Joseph Lister — antiseptic surgery
🩶 John Snow — traced cholera to contaminated water
🩶 Louis Pasteur — disproved spontaneous generation; supported germ theory
🩶 Robert Koch — proved microbes cause disease; Koch’s postulates
Germ Theory = microorganisms cause disease
🔬 2. Types of Microbes
Microbe Type Examples Key Characteristics
Prokaryotes Bacteria No nucleus; smaller and simpler
cells
Eukaryotes Fungi, Protozoa, Algae, Parasites Have nucleus; larger and more
complex cells
Acellular Agents Viruses, Prions Not true cells; require host to
function
