Unexplored reservoirs of pathogenic bacteria: protozoa and biofilms

Trends Microbiol. 1999 Jan;7(1):46-50. doi: 10.1016/s0966-842x(98)01425-5.


In the natural, industrial, hospital and domestic environments, there are numerous phenotypes of pathogenic microorganisms, which vary considerably in chemical, physical and biological properties. A link exists between survival, resistance and virulence. In particular, surface-adherent biofilms and bacteria living within protozoa pose potential health problems that are unrecognized by conventional laboratory culture methods.
