Patogen [grčki pato i gennan˭da proizvedu] je bilo mikroorganizam izazivač oboljenja. Patogenost je sposobnost mikroorganizma da proizvode patološke promene ili bolest. Primarni patogen svaki organizam koji uzrokuje bolesti u zdravom domaćinu direktnom interakcijom. S druge strane, oportunistički patogen je organizam koji je normalno slobodan u okruženju ili je deo mikrobiote domaćina, ali koji može postati patogen pod određenim okolnostima, kao što je pad imunog sistema.
A pathogen [Greek patho, and gennan, to produce] is any disease-producing microorganism. Pathogenicity is the ability to produce pathologic changes or disease. A primary (frank) pathogen is any organism that causes disease in a healthy host by a direct interaction. Conversely, an opportunistic pathogen is an organism that is either normally free-living, or a part of the host’s normal microbiota, but which may adopt a pathogenic role under certain circumstances, such as when the immune system is compromised.
