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)
- Which term would best describe the occurrence of a disease that is not normally seen, yet occasionally a case will occur, such as tetanus? 1) endemic O 2) sporadic 3) epidemic O 4) pandemicMicroorganisms that cause disease only when the body is already immunocompromised in some way or when a member of the microbiota is wrongfully present in an unnatural anatomical area are called O virulent pathogens O colonizing patogens O opportunistic pathogens O primary pathogensDefine each of the following terms related to describing/categorizing infectious diseases: Communicable Focal Infection Incubation Period Occurrence Opportunistic Pathogen Pathology Prevalence Secondary Infection Septicemia Zoonotic
- Microbes possess many different strategies to help them cause disease called virulence factors. Explain how two virulence factors work. For each virulence factor state the name of the mechanism, explain how it works and what advantage it gives the organism that helps it cause disease.Which form of viral infection is described by this example? Long-term human papillomavirus (HPV) infection, during which a person shows few symptoms but is constantly producing low numbers of infective viral particles and can transmit the disease. Latent infection Persistent infection Acute infectionWhat is epidemiology? there are several ways pathogens can be transmitted including direct contact, indirect contact, via respiratory droplets, vehicle, and through a vector. Describe each mode IN DETAIL and give an example of a pathogen that can be transmitted each way.
