a pathogen forms a compatible interaction with the host?
true or False
Step by step
Solved in 2 steps
- Describe the course of infection from contact with the pathogen to its exit from the host.The first stage of pathogenesis is evasion of the hosts immune system entry to the host colonization of the host replication in the host adhesion to the hostWhich type of interaction is least harmful to the host?
- What is meant by an opportunistic pathogen?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 infectionDisease Mode of infection prevention Syphilis Cholera Hepatitis Obesity Guinea worm
- Match the cells structure or chemicals with their role in the infection processportal of entry opportunistic Infection morbidity pathogen healthcare-associated infection virulence factors pathogenicity toxemia Entry into the host by a which can cause disease in a healthy host pathogen can be via a which can cause disease in an immunocompromised host which can establish can lead to attachment and avoidance of host defenses, which depend on may be caused by normal biota may be caused by drug- resistant microbes such as enzymes and toxins that may trigger may enhance which together with fever other signs and symptoms define a ResetBelow 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)
