Summary
An outdoor airborne mold survey in Edmonton found Rhodotorula and common Hormodendrum year-round. Molds were prevalent seasonally, peaking in spring and early summer, suggesting periodic surveys for immunotherapy practices.
Area of Science:
- Environmental microbiology
- Aerobiology
- Allergen monitoring
Background:
- Outdoor airborne molds are significant environmental factors.
- Understanding local mold prevalence is crucial for public health and clinical practice.
- Previous surveys in the Edmonton area may not have fully characterized seasonal variations.
Purpose of the Study:
- To conduct an outdoor airborne mold survey in the Edmonton area.
- To identify prevalent mold species and their seasonal distribution.
- To inform clinical practices, particularly immunotherapy, based on local mold data.
Main Methods:
- Airborne mold sampling was conducted in the Edmonton area.
- Collected samples were analyzed to identify and quantify mold species.
- Data was analyzed to determine seasonal prevalence patterns.
Main Results:
- Several previously unrecognized molds, notably Rhodotorula, were identified.
- Hormodendrum was the most frequently identified mold, present throughout the year.
- Outdoor molds were prevalent across all seasons, with higher concentrations observed in spring and early summer.
Conclusions:
- Outdoor mold presence is a year-round phenomenon in Edmonton.
- Seasonal variations in mold prevalence, particularly peaks in spring and summer, are significant.
- Periodic outdoor mold surveys are recommended for clinicians utilizing mold immunotherapy.
