Persistent infections are characterized by the continual presence of the infectious organism, often as latent infection with occasional recurrent relapses of active infection.

As enterococci are present, there's a chance other more infectious organisms that cause gastrointestinal infections could be there.

After transferring the infectious organisms to the host species, the flies leave to rest and during that time transmission was successful only in some cases.

Such substances include infectious organisms such as bacteria and fungi as well as other materials such as keratin and suture fragments.

Present-day analysis shows that they can be composed of coagulated fibrin including platelets, focal ischemia, inflammatory infiltrate, infectious organisms, or neoplastic cells.
