Infectious agents that have been linked to atherosclerotic disease include, but not limited to Chlamydia pneumoniae, Porphyromonas gingivalis, Helicobacter pylori, influenza A virus, hepatitis C virus, cytomegalovirus (CMV), and human immunodeficiency virus (HIV).

Inhibition of Cell Wall Synthesis: Beta-lactams Inhibits peptidoglycan formation by irreversibly binding to enzymes that link NAM subunits in the cell wall. Bacterium lyses.

Dengue fever is an acute febrile illness with sudden onset of fever, followed by development of generalized symptoms and sometimes a macular skin rash. It is known as “breakbone fever” because of severe muscle, joint and bone pains.

Which type of hemorrhagic fever can be treated with ribavirin? Dengue fever.

Blood-borne viruses (BBVs) are viruses that some people carry in their blood and can be spread from one person to another. Those infected with a BBV may show little or no symptoms of serious disease, but other infected people may be severely ill.

Integrase inhibitors The integrase enzyme binds to host cell DNA, prepares an area on the viral DNA for integration, and then transfers this processed strand into the host cell’s genome. Integrase inhibitors stop the virus from inserting itself into the DNA of human cells.

Main Targets for Antiviral Drugs Specific events in virus replication identified as targets for antiviral agents are viral adsorption, penetration, uncoating, and viral nucleic acid synthesis as well as viral protein synthesis.

Which structure is found only in poxviruses? Nucleosome.

Which is correct about influenza? Selected Answer: Correct The virus is grown in poultry eggs for vaccines. All of the choices are correct.

Which of the following is correct about polio? Selected Answer: Correct The virus multiplies in the mucosa of the intestines and is shed in feces. Selected Answer: Correct can cause high fever, pneumonia, respiratory distress.

What is the function of normal biota of the respiratory tract? to perform the important function of microbial antagonism.

Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction (the lytic cycle being the other). Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium’s genome or formation of a circular replicon in the bacterial cytoplasm.

Good hygiene: the primary way to prevent infections

1. Wash your hands well.
2. Cover a cough.
3. Wash and bandage all cuts.
4. Do not pick at healing wounds or blemishes, or squeeze pimples.
5. Don’t share dishes, glasses, or eating utensils.
6. Avoid direct contact with napkins, tissues, handkerchiefs, or similar items used by others.

Lytic “life” cycle of viruses. Viruses can interact with their hosts in two distinct ways: the lytic pathway and the lysogenic pathway. Some viruses are able to switch between the two pathways while others only use one.

These stages include attachment, penetration, uncoating, biosynthesis, maturation, and release. Bacteriophages have a lytic or lysogenic cycle.

Viral pathogenesis comprises of several stages, including (1) transmission and entry of the virus into the host, (2) spread in the host, (3) tropism, (4) virulence, (5) patterns of viral infection and disease, (6) host factors, (7) and host defense.

They can manufacture their own ATP, proteins, and nucleic acids. They can use the host cell to copy themselves and make viral proteins. They can use the host cell to copy themselves and then synthesize their own proteins inside the viral capsid.

Ebola virus disease (EVD) is a deadly disease with occasional outbreaks that occur mostly on the African continent. EVD most commonly affects people and nonhuman primates (such as monkeys, gorillas, and chimpanzees).

Bacteriophage: ↑ A virus that infects bacteria, also called a phage.
