Document Summary
Scientific knowledge base: nature of infection i. If the pathogens multiple and cause clinical signs and symptoms, the infection is symptomatic v. If clinical signs and symptoms are not present, the illness is asymptomatic: chain of infection, occurs in a cycle that depends on the presence of all of the following: Infectious agent or pathogen: reservoir, port of exit from the reservoir, mode of transmission, port of entry to host, susceptible host ii. Ideal temp for most human pathogens: 20 to 43 c (68 to. Reproductive tract: blood, modes of transmission, direct, indirect, droplet, airborne, vehicles, vector, direct: physical contact between reservoir and susceptible hose, includes transmission through vectors. Indirect: vehicle transmits pathogen from reservoir to susceptible host: droplet, airborne, port of entry, susceptible host, susceptibility depends on the individual"s degree of resistance ot pathogens, course of infection, box 28-1, p. 401, box 28-2, p. 401.
