1. BACTERIA BY: CHEYMAN GARBER, DANA BORINE, ALEXANDER TOWLE

2. HELPFUL BACTERIA Within our own bodies bacteria makes us nutrients that we cannot survive without Certain bacteria degrades organic compounds and in return makes soil the earth needs to produce plants

3. HELPFUL BACTERIA Bacteria is used to break down sewage and clean up oil spills Since bacteria reproduces so quickly it can make helpful proteins such as insulin very quickly which can then be made into large vats

4. HARMFUL BACTERIA Pathogenic Bacteria may infect people and cause disease Pathogen: - Anything that causes disease -A group of microscopic organisms that can reproduce on their own which can then cause disease by direct invasion of body tissue Over-usage of antibiotics have led to antibiotic-resistant bacteria

5. HARMFUL BACTERIA Certain bacteria can spoil food and make water unsafe for consumption Bacteria is also the cause for bad and potent odors

6. THE USAGE OF ANTIBIOTICS What we use antibiotics for... Salmonella Scrapes Ear Pain Sinus Infection UTI

7. HOW DISEASES ARE SPREAD? Physical contact sexual contact or through the air Contaminated water or food food poisoning and uncooked meat poor sanitation and untreated sewage Infected animals vectors- animals that carry pathogens from person to person ex: malaria, rabies, Lyme disease

8. HOW TO PREVENT DISEASES FROM SPREADING physical contact covering mouth when sneezing and coughing washing hands contaminated water or food cook properly

9. PENECLIN in 1928, Alexander Fleming was growing Staphylococcus and saw that penecilin contaminated the culture dish Bacteria does not grow near penicillin It’s a antibiotic Antibiotic- interferes with the growth of bacteria

10. TETRACYCLINE Antibiotic Treats urinary tract infections, acne Prevents attachment of tRNA to RNA complex Inhibits certain steps of protein biosynthesis

11. MACROLIDE An antibiotic Ex: Biaxin and Clarithromycin Treats common infections Inhibits protein synthesis

12. DISINFECTANTS AND ANTIBODICS Antibiotics and Disinfectants: used to kill and prevent growth of bacteria Antibiotics: disrupt one or a few parts of microorganisms and have relatively little toxicity to the body Disinfectants: destroy many components of microorganisms at once and not safe to ingest or inject

13. DISINFECTANTS harm prokaryotic and eukaryotic cells used on abiotic surfaces typically used on our skin but not in our bodies

14. ANTIBIODICS work on prokaryotic bacteria kill bacteria keep from bacteria reproducing fight infections caused by viruses such as colds flu most coughs, bronchitis sore throats usually caused by strep
