A patient is admitted to the hospital with a viral infection and is immediately treated with broad-spectrum antibiotics. How will the course of the infection be affected by this treatment? The infection's length will remain the same because viruses do not have DNA or RNA, and so antibiotics do not affect them. The infection's length will be shorter because antibiotics can prevent viral entry into the cell by binding to host-receptor proteins. The infection's length will remain the same because antibiotics have no effect on eukaryotic cells or viruses. The infection's length will be shorter because antibiotics activate the immune system, and this decreases the severity of the infection.

An antimicrobial drug binds to the HIV reverse transcriptase enzyme, preventing it from working. Which of the following is true of this drug? It would inhibit early replication steps of some viruses, but not affect normal eukaryotic cell activity. It would directly interfere with translation of some viral proteins and some eukaryotic proteins. It would block assembly/maturation steps of some viruses, and interfere with translation in eukaryotic cells. It would interfere with release of newly formed viruses from a host cell, but not affect eukaryotic cells. It would interfere with protein synthesis in bacteria, but not affect eukaryotic ribosomes. It would interfere with mRNA transcription in bacteria and viruses, but not affect eukaryotic transcription.
Which of the following is one way a virus can enter the host cell? Depending on the type of virus, each of the choices is a potential entry mechanisms. A virus can gain entry by fusing its membrane with the host cell's membe to transfer its genome into the host cell. A virus can gain entry by injecting its genome into the host cell. A virus can gain entry by fusing with the host cell's membrane so that the entire virus enters the host cell.
In electron micrographs of HSV infection, it can be seen that the intact virus initially reacts with cell-surface proteoglycans, then with specific receptors. This is later followed by viral capsids docking with nuclear pores. Afterward, the capsids go from being full to being "empty." Which of the following statements best fits these observations? The viral envelope is not required for infectivity, since the envelope does not enter the nucleus. The viral envelope mediates entry into the cell, the capsid mediates entry into the nuclear membrane, and the genome is all that enters the nucleus. Only the genetic material of the virus is involved in the cell's infectivity, and is injected into the host cell like the genome of a phage. Viral capsids are needed for the cell to become infected; since the full capsids enter the nucleus.
Can the below be added to the answer: Some common cytopathic effects include: Cell rounding and detachment: The infected cells may become rounded and detach from the underlying surface, leading to cell death and tissue damage. Cell lysis: In lytic infections, the virus utilizes the host cell's resources to produce new virus particles. As a result, the infected cell eventually bursts (lysis), releasing the newly formed viruses, which can go on to infect neighboring cells. Formation of inclusion bodies: Some viruses induce the formation of distinct structures called inclusion bodies within the infected cells. These inclusion bodies are often aggregates of viral proteins or nucleic acids and can be visualized under a microscope. Cell fusion: Certain viruses have the ability to cause infected cells to fuse together, forming multinucleated giant cells. This fusion enhances viral spread and can lead to the destruction of affected tissues. Cellular damage and functional impairment: Viral…
each virus bind to a specific cell surface receptor for attachment, so prevention of viral attachment how would you create a drug which will prevent viral attachment.
Which of the following highly contagious viruses is a single-stranded ribonucleic acid (RNA) virus with a helical capsid and envelope and is transmitted by coming in contact with respiratory secretions? "This is a highly contagious respiratory illness transmitted when an infected person coughs or sneezes virus particles into the air," the health department said in a written statement. "It's so contagious that if one person is sick and spreading measles, nine out of 10 people around them who aren't immune will get it, too." Group of answer choices a. Measles b. Parvovirus c. Coxsackie virus A d. Rhinovirus
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?
How common is ABV in the USA? In the United States, over half of adults have been infected with ABV by age 40. Once ABV is in a person's body, it stays there for life and can reactivate. Match terms with descriptions based on the text above. You can use an answer more than once or not at all. "Over half of adults have been infected with ABV by age 40." ABV could belong to this group of viruses: A. Human Papilloma Viruses B. Incidence of ABV C. Herpesviruses D. Prevalence of ABV by age 40
Considering that each virus must bind to a specific cell surface receptor for attachment, explain how you would create a drug that prevents viral attachment.
The diagram below shows the Covid-19 virus with its spike protein. It also shows the area on the spike protein which binds to the ACE2 receptor (receptor binding domain). Corona Virus Receptor Binding Domain (RBD) Spike Protein In order to get into a cell, the Covid-19 virus needs to bind to the ACE2 receptor. Once bound it is brought into the cell. These receptors are found on cells making up various tissues (oral and nasal mucosa, nasopharynx, lung, stomach, small intestine, colon, skin, lymph nodes, thymus, bone marrow, spleen, liver, kidney, and brain). The symptoms for Covid-19 are linked to the tissue cells the virus infects. To the right is a diagram showing the biding of the spike protein to the ACE2 receptor.

Viruses can easily mutate exchange genetic material, mechanisms referred to as antigenic drift and antigenic shift. These changes allow the virus to evade the immune system defenses.
