Carrier
Asymptomatic host and can transfer to susceptible individuals or different site on self
Nosocomial
Hospital or healthcare acquired. Often multi abx resistant

microorganism multiplies at normally sterile site
Colonization
Newly introduced microorg outcompetes normal flora and multiplies
Contamination
