Concept explainers

Virus

Viruses are infectious microscopic agents that can only reproduce in live cells of animals, plants, or microbes and are smaller than bacteria. Vertebrates, invertebrates, plants, protists, and fungi are among their many hosts. Viruses are unable to multiply on their own due to the lack of necessary cellular machinery, but they can guide the cell machinery of a host to make additional viruses by infection. The virus enters and attaches to a particular host cell, injects its genetic material, and reproduces by using the host’s genetic material. Viruses cause infection by taking entry into the host cell and using the host cell’s enzymes and raw materials to multiply.

Question

Viruses are obligatory parasites. When bacteriophages infect a cell, there would be two possible outcomes regarding the fate of that bacterium.

Can you describe the structures and life cycles of the T-even bacteriophage in detail?

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Viruses: a. Describe the structure and composition of viruses. What are three reasons that they are different from cellular organisms? b. Describe what a lysogenic bacteriophage is and how it is different from a lytic bacteriophage. c. Describe what is similar and different about the lifecycle of a non-enveloped DNA animal virus compared to an enveloped animal retrovirus.
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
A number of retroviruses can infect certain human cells. List two of them, briefly describe the medical implications resulting from these infections, and describe why only certain cells are infected.
Coronaviridae is a virus “family.” There are actually many different coronaviruses within this group, including less pathogenic virus strains that cause the common cold. Many people in this course have likely been infected with one of these other coronaviruses. A common feature of coronaviruses and other RNA viruses (think influenza virus, HIV, etc.) is that they mutate frequently. This is because the viral enzymes that copy the genome during replication can’t fix mistakes. Given this information, how might we be able to distinguish the SARS-CoV-2 strain from some of the other, less concerning, coronavirus strains?
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. Match each term with the correct definition Antigenic drift [ Choose ] [Choose ] Different strains of a virus or strain of different viruses, combine and form a new strain that now has a mixture of the surface antigens Antigenic shift The virus changes genetically by accumulating mutations within the genes that code for antibody-binding sites
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
You are studying your favorite (hypothetical) bacteriophage named M277. It infects E. coli and stays dormant within the bacterial cell. How does a phage become dormant within a cell? Generally, describe the steps of infection by phage in this scenario
Would you be able to help with this? Number 1. I’ve watched the video and can’t figure it out :/
a. During which stages of an infectious disease does the host exhibit signs and symptoms? Is there a correlation between this and when a disease is communicable? b. Why are some viral diseases, like smallpox and polio, no longer seen in the United States? Why are many bacterial disease, like syphilis, no longer a death sentence? Think about how these two types of microbes infect humans. Why might we make an effort to treat viral diseases before infection but continue to treat bacterial diseases after infection? c. Based on the graph below, which pathogen is more virulent: Agent 1 or Agent 2? Explain. 100 Agent 1 LD5 = 400, Agent 2 LD50 = 600 25 100 200 300 400 500 600 700 800 900 1,000 Dose (organisms administered per animal) Percent mortality 75
The genome of a retrovirus can integrate into the host cell genome. What gene is unique to retroviruses, and why is the protein encoded by this gene absolutely necessary for maintaining the retroviral life cycle?
Rhinoviruses, the most common cause of colds, do not have a lipid envelope. Compared to enveloped viruses, these and other nonenveloped viruses tend to remain infectious outside the body longer, are more likely to be spread by contact with surfaces, and are less likely to be rendered harmless by exposure to hand sanitizer or hand washing. Explain how the lack of an envelope could contribute to these characteristics.
