How does Cytomagalovirus contribute to the virulence of the pathogen?
Step by step
Solved in 3 steps
- Why is Zika virus disease considered dangerous even though itrarely kills?Though the exact mechanism of a norovirus infection is not known, give a generalized account of how the norovirus could cause its signature symptoms, vomiting and diarrhea.The common herbs tarragon and thyme both contain caffeic acid, which is effective against viruses, bacteria, and fungi. Can you elaborate about caffeic acid and Cytomagalovirus infection? Thanks!
- Why is handwashing an important means to control the spread of norovirus?If someone told you they knew someone who had typhus, why would you ask them to be more specific, based on your knowledge of vector-borne diseases?Can Cytomegalovirus (CMV) release any toxicant? What I mean is if the virus perform any kind of chemical rection while inactive like when it is in the environment releasing toxins or when is active inside the host such as inside the human body?
- Humans are accidental hosts in many vector-borne diseases. Whatdoes this indicate about the relationship between the vector and themicrobial agent?Considering that CMV infects 50% of the adult population in the United States and 100% of the population in many other countries, why is there so little Cytomegalovirus disease in the world?If a person contracted MRSA and no antibiotics are working on them, how would you go about finding a way to treat their infection? Describe, in detail, how you would devise a plan to save their life utilizing your knowledge of bacteria and viruses.
