The Bad DN Causes bacterial infections and diseases Pathogens – Bacteria, microbes, or viruses that cause disease  Responsible for Bubonic Plague or Black Death Can infect food or water sources Causes death in under devolved, unsanitary countries  DN

The Good DN Bacteria are not all bad Cannot survive without them Makes food; cheese , yogurt, pickles Make proteins, later drugs (medicine) Gives plants Nitrogen to grow DN

The Good DN Bacteria breaks down many things Food you digest in your stomach Includes Petroleum Cleans oil spills to keep environment healthy  DN

Antibiotics DN Used to treat bacterial infections Including life-threatening contagious diseases Does not work on viruses Can cause harm if overused Creates harder-to-kill bacteria DN

How do diseases spread? Direct Contact Indirect Contact AG Person Person Mother Fetus Animal Person Linger on objects Infected droplets through sneezing or coughing Requires physical contact Occurs without physical contact AG

How do diseases spread? Food Contamination Insect Bites AG                                            Food Contamination Insect Bites Food infected with disease Infects many from one source Example: E Coli Travels host to host Mosquitoes, fleas, lice, ticks Examples: Malaria West Nile Virus Lyme Disease AG

Antibiotics Disinfectants AG Kill invading bacteria cells In humans Kill bacteria cells on objects  Destroy cell walls Cell wall building prevention Quickly kill bacteria when in contact Clump proteins together Dissolve membrane Examples: Penicillin & Cephalosporins Examples: Alcohols & Chlorine AG

Disease Prevention AG Good Health Vaccinations Smart traveling choices Wash hands Wise food preparation Safe sex Vaccinations Smart traveling choices AG

Penicillin Antibiotic that kills bacteria and prevents growth and spread Used to treat infections Ear infections Sinuses Throat and Lung Urinary systems Does not cure or prevent: Colds Flues Infections caused by viruses DJ

Penicillin Can be used to treat strep throat Kills bacteria and shortens time contagious Stops strep bacteria from spreading Symptoms of Strep Throat Fever Swollen Tonsils Nausea/ Vomiting Side Effects of Penicillin Abdominal Pain Nausea Mild Diarrhea Skin Rash

Tetracycline Antibiotic to fight infections caused by bacteria Treats many bacterial infections: Skin Intestines Respiratory Tract Urinary Tract Genitals Lymph Nodes Treats infections from infected animals and contaminated food Used when Penicillin cannot be used Using Tetracycline can harm unborn baby during pregnancy

What is Amoxicillin? Penicillin Antibiotic that treats bacteria Taken in pill or powder form Treats  bacteria caused infections: Tonsillitis, bronchitis, ear infections, pneumonia Combined with other antibiotics to treat stomach infections LC

What does Amoxicillin Do? Kills bacteria that cause an infection Side Effects of Amoxicillin: Stomach aches, rash, vomiting Bronchitis Symptoms: chest congestion, shortness of breath, wheezing, cough that brings up mucus LC

What are Macrolides? Treat many types of gram-positive bacteria Very broad spectrum Respond better to antibiotics, no outer membrane Turn violet during the gram test Bind to ribosomes to stop protein synthesis LC

What does Macrolides treat? Treats infections:  soft tissue infections, STD’s,  Treats intracellular pathogens: Legionella Pneumophia Symptoms of legionellosis: shortness of breath, high fever, nausea, headaches, muscle aches Side effects of Macrolide: nausea, vomiting, allergic reaction, buzzing in ears LC
