Question Transmission of MicrobesThe method in which an infectious agent transfers from one organism to another. This can occur by either direct transmission (direct contact between infectious host and susceptible host) or indirect transmission (which involves an intermediate carrier).Direct transmission is defined as person-to-person transmission of infectious agents through contact.Indirect transmission includes both vehicle-borne and vector-borne contact.Indirect transmission can come from fomites or from vectors. A vector is defined as any agent (person, animal, or microorganism) that carries and transmits an infectious pathogen into another living organism. Vectors can be biological or mechanical. Biological vectors occur when the pathogen lives inside the organism. Mechanical vectors are when the pathogen is carried by, but does not live in, an organism.Identify the type of transmission for each of the following examples:1. Housefly landing on cow dung, picking up tapeworm eggs on its footpads, taking off and landing on a hotdog bun, and depositing the eggs on the bun. 2. James sneezed into his hands and then touched the door knob to exit Sally’s office. Sally, a few minutes later, touched her door knob to leave her office. 3. Baby Osman sneezes while his father is cuddling him. 4. Julie is bitten by a mosquito that is infected with the malaria parasite Plasmodium vivax.

Instructions
Both draft and final report will have the same structure and sections, with different requirements of content. No APA formal formatting is required for this report. Follow the instructions regarding structure and references. The draft should contain all section headers as well as the information that is bolded (and marked with D).
Title
Complete scientific name of the microbe in italics, except for viruses (D)
Classification
Taxonomic classification of the microbe (D). Depending on the microbe, you can use a paragraph or bullet point list.
Structure
2-3 paragraphs
• State the size of your microbe (D).
• Describe the structure of your microbe:
o If a bacterium or archaeon, describe the cell wall, outer layer if applicable, and any other structures present (flagella, pili etc.)
o If virus, what nucleic acid they present, what is the shape of the capsid, and if it has an envelope.
o If a eukaryote, describe shape, cellular characteristics, any special structures, unusual nuclei etc.
• Chemical composition if relevant: your microbe may have a special coating of some kind, or present molecules that add resistance to its structure. Mention them briefly if this is the case.
Metabolism
• State if your microbe is auto/hetero/chemo/phototroph (and if it changes, explain how). (D)
• If it is a virus, describe its hosts (D)
• Add any interesting details about the metabolic habits of your microbe.
Disease/condition caused by your microbe
• Describe briefly the condition/disease caused by your microbe. If it causes multiple conditions, list them and focus on the most relevant/common/serious one.
• Describe signs and symptoms of the disease.
• Describe how is it diagnosed.
• Describe how to prevent it or treat it.
References
List at least 7 reputable sources: peer reviewed publications, institutional and academic websites (CDC, Medscape are ok, Wikipedia and individual or commercial websites/blogs not).

1.What are the antibiotics?
2.Commenly used in pharmacology?
3.give uses above that?

For this discussion, take on the role of a pathogen that infects the respiratory system, gastrointestinal tract, or genitourinary system. Write a narrative from the pathogen’s point of view about the following:
What is your name (scientific pathogen name)?
How did you get into the body?
What type of damage do you do to the body?
What will the body try to do to stop you?
Who wins? You or the body?
Use your own words. Use 2 scholarly sources (one being the one listed below). APA format. Cited.
Cowan, M. K., & Smith, H. R. (2024). Microbiology: A systems approach (7th ed.). McGraw-Hill.
After I will post the reply discussion.

Some diseases are known as anatomical syndromes because they have similar signs and symptoms despite having different causative agents. A few examples include impetigo, cellulitis, neonatal conjunctivitis, keratitis, meningitis, acute and subacute encephalitis, and sepsis. For the discussion this week, select two pathogens that cause one of these anatomical syndromes and then discuss
signs and symptoms of the disease,
the virulence factors of each of the two pathogens, and
a possible explanation for why two different pathogens cause the same disease.
or
Mosquitos are biological vectors for many diseases, including West Nile virus, malaria, and yellow fever. Some scientists have advocated for the elimination of mosquitos to prevent the transmission of these diseases. Write a discussion either in support of or against eliminating mosquitos.

Discussion:
For the Discussion Board this week, you will pretend to be an epidemiologist working at the Center for Disease Control and Prevention (CDC) in Atlanta, GA. An outbreak of a food-borne illness has occurred, and it is your job to report this to the public. Have fun with this!
Here are the specific directions for the Module this week:
1). Research a specific pathogen that would be involved in an outbreak of a food-borne illness. For example: Listeria monocytogenes, Salmonella, Clostridium botulinum, Clostirdium perfringens, Staphylococcus aureus, Bacillus cereus, etc.
The following references (and many others) may be helpful.

2). Present your case study to the class. In your presentation, please include the following information:
Where and when your ‘outbreak’ occurred and how many cases have been reported
The specific food source that was linked to the outbreak
The specific pathogen responsible for this outbreak
How was this pathogen identified as the cause of this outbreak?
5. The morphology of the organism: What is the Gram stain result?
The signs and symptoms that would be seen in the patient as a result of this infection
What the public needs to know about how this infectious disease can be treated and prevented
Options for presentation:
1. Post a 3-5 minute video of your announcement. Make a 3-5 minute video informing the public about this
outbreak and how to prevent it. For this video, you can use your own technology and upload the file to your
discussion board site or you can create this right in your discussion board response. To do this, click on the
‘Reply’ tab in your discussion board. Click on the ‘film’ icon on the tool bar. Create and save your video.
2. Create Prezi presentation or a Powerpoint presentation including all of the required information.
3. Remember that you must include at least 2 scientific references in correct APA format.
3). Review your peers’ presentations and have fun responding to at least 2 of these. Please add some information
about the specific pathogens discussed in order to have a more meaningful discussion.
note I rally would like you to Create Prezi presentation or a Powerpoint presentation. let me know if you need anything else
