Fungi (molds) in the Air

  • Diverse sources: Agricultural and non-agricultural environments.

  • Winds: Major vehicle for transport from sources to other environments

Fungi (molds) in the Air

  • Outdoors and Indoors

  • While you are taking this quiz, you are probably inhaling fungal spores. Which of the following are least likely to be in the air now in the room?

  • A. Conidia

  • B. Sporangiospores

  • C. Zoospores

  • D. Asexual spores

  • E. All of the above

  • F. None of the above

  • Concern: load in the air

Sampling Methods

  • High-volume dust collectors

  • Exposure of petri plates containing growth media outdoors

  • Volumetric air samplers (single-stage and 6-stage Andersen samplers)

  • Rain water collection

  • Sticky tapes mounted on glass slides
