Transient FloraIt is derived from the environment, does notproduce disease, and does not establish itselfpermanently on the surface Members of the transient flora are generally oflitle significance so long as the normal residentflora remains intact If the resident flora is disturbed, transientmicroorganisms may colonize, proliferate, andproduce diseaseSHIHEZIUNIVERSITY
