The biofilm can present one of the most important species of microorganisms, depending on the duration and its location. Gram-positive, Gram-negative and yeast. In addition, the cellular elements may be attached to the biofilm, such as platelets, for example, when the biofilm is installed on the blood-soaked surface.Several factors contribute to the formation of biofilms.

The physical chemical properties of the surface, the nutritional composition and ambient temperature will also interfere with this speed. The presence of antimicrobials in the medium may affect the formation of biofilms.
