What Do We Really Need To Know? basic characteristics how they infect a host what diseases they cause how they can be stopped.

How Viruses Attack Viruses and Bacteria

There is a HUGE difference in their sizes. Viruses are 1/10th to 1/100,000th the size of a bacterium. Bacteria are 1/10th to 1/100,000th the size of a protist

What is a virus? A non-living container of DNA. Not a cell Must use another organism to reproduce Viruses - Basic Characteristics

Virus Structures and Examples

How We Get Viruses ･ Exposure to infected bodily fluids through activities such as sexual intercourse or sharing hypodermic needles. ･ Sneezes! ･ Coughs ･ Bites from infected animals or insects

Once a virus has found a new host…

Diseases Caused By Virus Measles, mumps, rubella, polio, encephalits, diptheria, chicken pox, small pox, mono, warts, …and also colds, flu, HIV, yellow fever,herpes, bird flu, hepitiusA/B and many more! Polio Victim Flu epidemic of 1918 …viral pneumonia...

How do You Stop A Virus? Immunizations Natural antibodies Avoid others who are infected Wash your hands Maintain a strong immune system Monoclonal antibody

What are Bacteria? Different bacteria can “eat” everything from sunlight, to sugar to iron and sulfur, and may emit toxins as waste products. Single-celled prokaryotes with tiny flagella. They can be found everywhere and in large amounts. 100,000 / square inch of skin; 1,000,000,000 /teaspoon of dirt.

Sphere-shaped bacteria (cocci) sometimes grow in chains or in clumps like a bunch of grapes. Rod-shaped bacteria (bacilli) can also form in chains. Spiral-shaped bacteria (spirilla) can use their shape to propel themselves by twisting like a corkscrew. Bacteria Forms

Diseases Caused by Bacteria Whooping Cough ･ Leprosy ･ Tetanus ･ Salmonella ･ Botulism Scarlet fever ･ ･ Leprosy ･ Tetanus ･ Salmonella ･ BotulismScarlet fever Ear AcheEar Ache Strep throat ･ Cholera ･ Dysentery Gonorrhea ･ Anthrax ･ Diphtheria ･ Syphilis ･ Tuberculosisthroat ･ Cholera ･ Dysentery Gonorrhea ･ Anthrax ･ Syphilis ･ Bacterial Pneumonia Tetanus Leprosy And don’t forget Septicemia!

How Bacteria Invades Coughs or sneezes! Close contact with an infected person Contact with feces Cuts Indirectly, by touching contaminated surfaces Drinking contaminated water Eating contaminated food without cooking it thoroughly.

How Prevented/Cured/Manged Antibiotics Disinfectants Clean water Cooking meat throughly WASHING HANDS!!!!

…and I’d wash carefully after wearing that meat, too…

Protists Stained Volvox and Amoebas

Basic Characteristics Of Protists Single-celled eukaryotes Live in water Everyone classifies differently Can live in colonies so they look big, like kelp. Giardia Kelp

Sickness Caused By Protists Pfeisteria -pfeisteria dinoflagellate Malaria - plasmodium Amoebic dysentery -Entamoeba histolytica Pfeisteria dinoflagelate Most protists are benign to humans.

How They Infect Consumed in dirty water Mosquito bites Uncooked food

How to Prevent Infection Clean water Insecticides, anti-malarial medicines Cooking food thoroughly

Eat decomposing organic material Like moist areas Come in many forms Macroscopic and microscopic Fungi Characteristics

Mycelium and hyphae structure

Sicknesses Caused by Fungi Ringworm Athelete’s Foot Yeast Infection Poisoning

How fungi infect Spores carry on the wind everywhere. Athelete’s Foot - direct contact with fungus on surfaces Bacteria/fungal imbalance

How Prevented/Cured Fungicides Good hygene Avoiding fungus-friendly surfaces Don’t eat wild mushrooms!

What’s on Tuesday’s Test? All this info about small things that kill you: Viruses, bacteria, fungus, protists: –What they look like, misc. important information, diseases caused by, how to prevent.

What Do We Need To Know About Cells? How to use a microscope Cell Theory The difference between animal and plant cells. Role and function of the cell organelles. Cell processes: photosynthesis, respiration, and mitosis/meiosis.
