Degree of virulence - Study guides, Class notes & Summaries

Agonist - Competitive inhibition, binds to active site and causes a signal response in receptive tissue. Antagonist (blocker) - Competitive inhibitor, binds to active site so signal molecules cannot bind but causes no response in receptive tissue, can bind and release eventually. Apply your understanding of channels and synapses to predict how various neurotoxins affect nervous function. - Neurotoxins block receptor proteins on the post-synaptic neuron. Example: tetrodotoxin form Fugu fish...

Third party reprocessors are regulated by FDA Which of the following is a not susceptible host Trauma patient, Patients undergoing radiation therapy, Patient of inadequate Nutricia al status There are many opportunities for Central Service Technicians to interrupt the chain of infection True The path used by infectious agent fro. Reservoir to enter a susceptible host is Portal of entry The ability of an organism to invade the host and cause disease Pathogenicity...

Colonization correct answers an attachment to and replication in/on a host Infection correct answers a colonization of the body leading to damage Disease correct answers any deviation from health -not all disease is due to infection -infection does not always cause disease Symptoms correct answers subjective evidence of disease (pain, headache) Signs correct answers objective evidence of disease (rash, fever) Why do microbes cause disease? correct answers -Pathogens evolved to ...

Pathogenicity - ability to cause disease virulence - degree of pathogenicity invasiveness - ability of a bacterial pathogen to rapidly spread through tissue and cause destruction to surrounding tissue exotoxins - Proteins *ex*creted by bacteria with power to inactivate or kill host cells endotoxins - chemical components of the cell walls of certain bacteria At bacterial death, *endotoxins are released* causing inflammation, fever, chills bacteria differentiation - staining (gram +/-) sha...

Which of the following is the most effective way to reduce the number of nosocomial infections? handwashing What is the role of epidemiology? To learn how to treat and prevent various diseases. Which of the following types of diseases develops rapidly and only lasts a short time? acute disease The viral pathogen that causes cold sores can remain inactive in the body for a long time between disease outbreaks. How is this disease classified? It is a latent disease. A young man dies after eatin...

acute disease disorder with sudden onset, relatively severe, and short duration of symptoms chronic disease less severe but of long and continuous duration, lasting over long time periods, if not a lifetime communicable disease a disease that is contagious, or capable of being communicated or transmitted cause a factor that contributes to cause disease; may include intrinsic host factors as well as the agent and the environmental factors of the agent-host-environment triad risk...

1.Etiological Agent - The presence of an infectious agent is a necessary condition for an infection to occur. 2.Reservoir - Common sources are humans, plants, animals, or the general environment. 3.Portal of Exit from reservoir - Places by which the microorganisms can leave the reservoir to reach other surfaces/places. 4.Route of Transmission - A route permitting to reach another person or host though a portal of entry. 5.Portal of entry - This is how the infectious agent enters another p...
