Microbiology: Give an example of a microorganism showing Pathogenicity and an example of a microorganism showing high Virulence.

Order: Mycostatin 150,000 U stat  availablity : 100,000 Units    prepare a dose: using the label attached

Direct contact with pathogenic microorganisms is the most common cause of hospital-acquired infection. How might a dermal (skin) Staphylococcus infection of a staff member result in a urinary traction infection of a patient? Describe possible pathways of contamination during a normal workday.

of bacteria. The Gram stain works because of differences in the O 1) cell membranes O 2) genetic characteristics O 3) capsules O 4) antigens O 5) cell walls

Foodborne pathogens often require the presence of a large number of microbes before an active infection results. These microbes would have a high Group of answer choices virulence. incubation period. mortality. median lethal dose (LD50). median infectious dose (ID50).

Explain the significance of any two historical achievements in proving the role of microorganisms in human health and disease and maintaining the health of the environment. Be sure to describe the current classification of microorganisms.

State something about Bt toxin.

The success of a pathogen in invading an organisms depends on the number and the pathogens. O visibility O adhesiveness adherence O quality of

Interactive Microbiology: The Human Microbiome ← microbiota microbial antagonism transient parasitism opportunistic infections resident commensalism mutualism pathogenic infections The normal disease. Symbiotic relationships fall into one of three categories: benefits and the other is unaffected; consists of all the microbes that live on or in the host and that do not cause host. II The organisms are only present for only a short period of time in the body. Through microorganisms from establishing themselves. The normal microbiota exhibits in which both organisms benefit; and in which one organism benefits and the other is harmed. , in which one organism microbiota are long-term residents of the body, whereas the normal microbiota benefits the host by preventing pathogenic which protects the host from may occur when members of the normal microbiota colonize abnormal regions of the ASUS

Differentiate between normal microbiota and transient bacteria found on skin. Which type is more difficult to remove? Explain.
