What causes Saturday 4 Ja nuary 2025 malaria? 1 What is a pathogen? A microorganism that can cause disease 2 Is human skin a specific or non- non-specific specific defence against pathogens? Sexual contact or exchanging 3 bodily fluids How is HIV spread? Kill or low growth of bacteria 4 How do antibiotics treat bacterial infections? Damage bacterial but not host 5 Why are antibiotics not damaging cells to the animal or plant being given antibiotics? CHALLENGE: Name the four types of pathogen. For each pathogen give one example of a disease caused by this pathogen. Activating prior knowledge: Pathogens Virus Bacteria fungus Protists The image shows a house fly. Why can a house fly NOT be a pathogen? 1) They are clean and cannot 2) They are not a microorganism infect food 3) They do not help spread 4) A fly can be a pathogen as it disease causes disease Malaria worldwide risk Malarial protist  What causes malaria?
