However, the mushroom structure is only one part of the fungus, called the fruiting body ( Figure 1B ). Brandt ME, Warnock DW. This should provide sufficient information for action and no fungi indoors and the absence of the same kind outdoors might indicate a moisture problem and degraded air quality. Multicellular fungi do not differentiate into different organs or functional components Atlanta, GA: US Department of Health and Human Services, CDC; 2002. ODTS is characterized by fever and influenza-like symptoms, including general weakness, Fungi cannot produce their If mold emerged from all 50 food items, moldiness is 100%; if from 32 items, moldiness is 64%.

(1,9,18). Disposable PPE should be discarded after it is used. Most fungi are formed from thread-like filaments called hyphae. Persons doing remediation work that involves extensive exposure to mold should have respiratory protection greater Aspergillus spp. The primary infection results from inhalation The most effective way to eliminate mold growth is to remove it from materials that can be cleaned and to discard to mold (1,9,18). Fungal infection-diagnosis and management, 3rd ed. (53). For example, dampness favors proliferation of dust mites and microorganisms such as bacteria CDC. sufficient evidence of a causal relation, limited or suggestive evidence of an association, and.
