- 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.

Choose two of them and answer the following questions: 1. Is it an exotoxin or an endotoxin? 2. Which bacterial species produces it? 3. Briefly describe its mode of action and how it causes damage to the host cells. Include specific signs and symptoms.Below are a list of virulence factors/ strategies paired with an example of an organism that utilizes them. How do each of the following strategies contribute to the virulence of the pathogen? Strategy - Causes the host to produce more receptors (Organism - Rhinovirus) Strategy - Produces gas as a product of fermentation (Organism - Clostridium perfringens) Strategy - Produces a capsule (organism - Klebsiella pneumonia) Strategy - Ability to move between adjacent cells (organism - Cytomegalovirus) Strategy - Ability to use pilus as a motility structure (organism - Pseudomonas aerogenosa)
- For any diseases caused by a virus: What is the name of the disease? What bacterium or virus or plasmodium causes the disease? Name the vector responsible for the transmission.

- Explain how animal viral infections are treated and detected.answer correctA 42 year old man developed a “flu-like” syndrome with fever, sore throat, headache, and myalgia. Viral culture was ordered for laboratory confirmation of influenza. Which of the following would be the best specimen for isolating virus responsible for the infection? A- Blood B- Nasopharyngeal washing C- Stool D- Saliva E- Vesicle fluidFor each of the following: Cyanobacteria, Coronavirus, Chytrids, Ciliates, and Chronic wasting disease. Explain with details how does the pathogen invades our tissues and body after transmission. You need to include any receptors, steps etc. in its life cycle and/or the type of replication or reproduction it exhibits and how and where it exits the cells, tissues, or body. This section can also include how it spreads through the body if that is relevant.
