Vaccinations and Antibiotics Protists-eukaryote that is not plant, animal, or fungi that can cause serious diseases ex. Malaria -Drugs and vaccines can be very effective against them. #1 barrier from infection is skin and mucuos membranes **Sweat, tears, mucus & saliva: contain lysosomes/enzymes that kill bacteria Fighting bacterial infections: 1. Antibiotics compounds that block growth & reprod. of bacteria • If stopped early, not all bacteria destroyed • Antibiotic Resistance = remaining bacteria mutates & is unaffected by antibiotic 2. Sterilization – using high heat to kill bacteria 3. Vaccination • made from “dead” or weakened pathogens • stimulates immune system to protect against pathogen in the future 4. Macrophages attack at infection site-antibodies are made if they don't work 5. Antibodies = proteins in the body that help block/ destroy pathogens • made by white blood cells • blocks receptor sites so pathogens don’t attach Fighting Viral Infections: 1. Vaccination 2. Antibodies 3. Sterilization 4. Antiviral medication • Very few for viruses! • You CANNOT take antibiotics for viruses!
