1. Choose a pathogen that can invade the human body and research it in depth. Describe as many characteristics of the microscopic structure as possible, using size, shape (such as coccus), staining characteristics (such as Gram stain), or any detail other than its name. Include the transmission, etiology, and host of the disease. Try to provide a written "picture" in your colleagues' minds without directly giving away the answer. Your description must be complete enough to rule out any other answers and avoid confusion (check your work by researching your organism's characteristics before posting to be sure you could answer it yourself!) In your replies to this discussion, provide the name of the pathogen and your rationale for each response. Combine all of the information provided to choose one best,

3 Keep in mind the entire description. Although someone may describe an airborne bacterium that causes pneumonia, it does not necessarily mean the answer is Streptococcus pneumoniae. Staphylococcus aureus and Neisseria meningitidis both also have an airborne mode of transmission, cause typical pneumonia, and are both cocci bacteria, but one is Gram positive and one is Gram negative.

Pathogens are microorganisms that enter the human body unwittingly and have the potential to cause disease. Pathogens can be spread through skin contact, body fluids, airborne particles, or excrement contact. They can also transmit by touching a surface that has been touched by an affected individual.
The pathogen I've chosen is associated with disease in recent international events have heightened public concern about the possibility of biological terrorist attacks involving the disease that is caused by these pathogens. These infections are classified into three types, each of which affects the skin, lungs, and digestive system. It is a gram-positive, rod shaped bacterium which is transmitted from animal to human and It was discovered in 1876 by a German physician named Robert Koch and was the first bacterium to be experimentally proven to be a pathogen. Furthermore, the discovery also provided the first scientific support for the germ theory of disease.
The pathogen is a Gram-positive bacterium with an intricate parietal architecture. A thick peptidoglycan of the Al gamma type surrounds the cytoplasmic membrane. Only one related polymer is covalently attached to the peptidoglycan: a polysaccharide comprised of galactose, N-acetylglucosamine, and N-acetylmannosamine. An S-layer exists outside of the cell wall. The S-layer can be made up of two proteins. Their SLH N-terminal domain noncovalently binds to the cell wall polysaccharide. The antiphagocytic poly-gamma-D-glutamate capsule that covers the S-layer is dependent on environmental parameters that imitate the mammalian host, such as bicarbonate and a temperature of 37 degrees C.
It is a disease that is commonly found in grazing animals such as sheep, goats, cattle, and, to a lesser degree, pigs. Therefore, mostly person who are exposed to infected animals are at the risk of being infected. The bacteria can proliferate and spread throughout the body, producing toxins and causing serious sickness. Taking in spores, Consuming spore-contaminated
