Transcript of Bacteria
What, When, Where, and Why?
-mountains, rivers, oceans, humans, etc.
Bacteria are known to be the cause for many diseases, which is why we're studying them!
Asexual: binary fission
Other types of reproduction:
are the good kind of bacteria that live inside of us
Common types are lactobacillu and bifidobacterium
gastrointestinal conditions (ex. diarrhea and irritable bowel syndrome), oral health problems (ex. tooth decay)
spirillum, spirochete, vibrio
More types of reproduction
can increases white blood cells
helps turn waste products into energy
helps the human digestive system break down food
decomposes dead plants and animals
its the only living things that can fix nitrogen cells
Bacteria is the cause of many diseases/
illnesses such as...
What are some manifestations of bacteria in our lives?
So now what?
1. Where do they live?
2. How are they transmitted?
3. What can they do to you?
4. How is this treated?
5. How can you prevent it?
botulism (food poisoning)
1. intestines of people and animals
2. through contaminated water and food or through contact with animals or people
3. symptoms: stomach cramps, stomach tenderness, nausea, vomiting, or diarrhea
4. No antibiotics, drinks lots of fluids, don't take anti-diarrheal medications
5. washing hands, cook meat thoroughly, avoid raw milk, unpasteurized dairy products and juices, don't swallow water when swimming, wash things that have touched raw meet
1. lung disease
2. breathing in infected air particles, during or after viral upper respiratory infection, complications of viral illnesses, vomit into the lungs
3. symptoms/signs: high fever, shortness of breath or rapid breathing, chest pains, abdominal pain, sever fatigue, cough with green or rust colored mucus
4. Antibiotics, antiviral medications, fever reducers, cough medicine
1. in the throat or on the skin
2. contact with fluids from nose or mouth (saliva)
3. symptoms: fever, sore throat, headache, nausea, rash
5. stay at home. get a new toothbrush.
1. nose, throat, or bloodstream, brain, spinal chord
2. transmitted through saliva or mucus
3. symptoms: brain damage, hearing loss, brain disabilities, nausea, vomiting, increased sensitivity to light, confusion, etc.
4. antibiotics, IV, VACCINES
5. protection through vaccines, general hygiene
Several ways to identify bacteria.
1. MORPHOLOGICAL IDENTIFICATION
2. Differential Staining
3. Serological Methods
4. Flow Cytometry
5. Phage Typing
6. Protein Analysis
7. Nucleotide Sequences
Circles vs. Rods vs. Spirals
