Infectious Diseases NB 153

DISCOVER ACTIVITY- HOW DOES A DISEASE SPREAD? Names of people you have touched today Who might they have touched today?

infectious disease disease that can pass from one organism to another

organism that can cause disease pathogen

scientists & their ideas showed microorganisms cause disease microorganisms caused diseases killing microorganisms could prevent spread of diseases performed surgery under more sterile conditions infectious disease caused by specific pathogen Louis Pasteur Joseph Lister Robert Koch

Joseph Lister using a carbolic steam sprayer to spread a mist of carbolic acid.

In the 1800’s, surgery was performed under conditions that were very different from those used today.

Surgery today is performed in operating rooms that have been cleaned thoroughly to eliminate disease- causing organisms.

THENNOW

4 major groups of human pathogens 1. bacteria 2. viruses 3. fungi 4. protists – medmyst.rice.edu/index.html

1. bacteria 11 celled microorganisms pproduce toxins (poisons) ddiseases caused by bacteria: strep throat- streptococcus bacteria tetanus

Pictures Of Strep Throat Here are three pictures of strep throat. Notice the red flecks indicating a bacterial infection.

2. viruses smaller than bacteria cannot reproduce unless inside living cells

2. viruses chicken pox diseases caused by viruses: – cold – influenza (flu) – chicken pox

3. fungi molds, yeasts athlete’s foot

4. protists malaria The Anopheles mosquito carries the protist that causes malaria.

sources of pathogens 1. person  person 2. contaminated object 3. animal bite 4. environment

1. person to person transfer thru direct physical contact –kissing, shaking hands thru indirect contact –sneezing

2. contaminated objects towels water food silverware

3. animal bites

rabies

The Lyme disease bacterium, Borrelia burgdorferi, normally lives in mice, squirrels and other small animals.Borrelia burgdorferi It is transmitted among these animals – and to humans -- through the bites of certain species of ticks.

engorged deer tick

4. environment soil water
