Parasite - an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense

Oocyst - a thick-walled protective case in which Eimeria become infectious. This structure serves to transfer the parasites to new hosts

Sporocyst - a thin protective case within an oocyst that allows sporozoites to develop

Sporozoite - a motile stage of that is the infective agent

Excyst - the action of a sporozoite exiting a sporocyst inside the intestine

Sporulation - the oocyst becoming infective

Pre-patent period - the time between ingestion of an infective oocyst and initiation of oocyst shedding following parasite replication "in-the-gut"

Patent period - time of oocyst shedding

Inoculation - when birds have been given oocysts or have ingested oocysts

Relative humidity (RH) - the amount of water vapor present in air expressed as a percentage of the amount needed for saturation at the same temperature

Dew point - atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form (i.e. the temperature at which air becomes saturated).
