Mold growth in buildings has been shown to be associated with

adverse health effects. The fungal and bacterial growth on moistened

building materials has been studied, but little attention has been

paid to the other organisms spawning in the damaged materials. We

examined moist building materials for protozoa, concentrating on

amoebae. Material samples ( [Formula: see text] ) from moisture-

damaged buildings were analyzed for amoebae, fungi, and bacteria.

Amoebae were detected in 22% of the samples, and they were found to

favor cooccurrence with bacteria and the fungi Acremonium spp.,

Aspergillus versicolor, Chaetomium spp., and Trichoderma spp. In

addition, 11 seriously damaged samples were screened for other

protozoa. Ciliates and flagellates were found in almost every sample

analyzed. Amoebae are known to host pathogenic bacteria, such as

chlamydiae, legionellae, and mycobacteria and they may have a role

in the complex of exposure that contributes to the health effects

associated with moisture damage in buildings.
