Imagem de Giardia

Descrição:

This scanning electron micrograph (SEM) of an untreated water specimen extracted from a wild stream mainly used to control flooding during inclement weather, revealed the presence of unidentified organisms, which included bacteria, protozoa, and algae. In this particular view, it appears that a diatom had been fractured in the processing of this specimen. Surrounding this diatomic microorganism, was a large biofilm mass within, and around which were numerous protozoan amoeboid and bacterial microorganisms. See PHIL 11686 for a larger view of this diatom. For a colorized version of this image see PHIL 11701.
