|
|
Term
|
Definition
process in which an organism establishes a parasitic relationship with the host |
|
|
Term
Definition of transmission |
|
Definition
movement of organism from environment, vector, or another host to a new host |
|
|
Term
Definition of colonization |
|
Definition
the successful transmission, invasion and replication of the pathogen in the host with the development of clinically silent, asymptomatic or subclinical disease states |
|
|
Term
Definition of incubation period |
|
Definition
the variable time period from when the pathogen first enters the host until an evident disease state is reached |
|
|
Term
Definition of latent infection |
|
Definition
the microorganism has penetrated and replicated, but remains inactive in the host |
|
|
Term
Definition of the period of communicability |
|
Definition
the time when the organism is present in sufficient number to be shed and passed to others which may precede symptoms and continue through part or all of the clinical disease state and into convalescence (aka infectious period) |
|
|
Term
|
Definition
individual capable of transmitting the disease to others without having symptoms of the disease themselves |
|
|
Term
Definition of communicable disease |
|
Definition
the pathogen may be passed or carried from one person to another directly or indirectly |
|
|
Term
|
Definition
bacteria lacking cell walls (have cell membranes instead), host cell dependent |
|
|
Term
|
Definition
pathogen to reservoir to portal of exit to mode of transmission to portal of entry to susceptible host |
|
|
Term

|
Definition

|
|
Term
|
Definition
environment where organisma can live and multiply at specific stages of the organisms' life cycle |
|
|
Term
Definition of portal of exit |
|
Definition
how the parasite leaves reservoirs usually corresponds to the site of entry into the host (ex. feces, fluids) |
|
|
Term

|
Definition
contact, airborn, enteric, vector bourne (mosquitoes and WNV and fomites), nosocomial infections |
|
|
Term

|
|
Term

|
|
Term
|
Definition
inflammatory processes and local rxns, wall off/destroy/neutralize pathogens, can become chronic with destruction of healthy tissue |
|
