Airborne asthma allergens

t fungi and correlated the general family groups, the fungal genus, with precise location. Using the Geographic Information Systems they could address factors of geology, geography, vegetation abundance, atmospheric conditions and human activities such as industry and vehicle traffic that might influence fungal distribution.

Airborne fungi are a potential health hazard to everyone. They can impact human health in four main ways: infecting people, acting as allergens, they can be toxic and carcinogenic, or they can cause inflammatory reactions.

Rivera Rentas and colleagues found that two particular fungal groups - Cladosporium and Mycelia sterilia were more common than others. When they classified the sampled regions they saw that four of the six locations sampled having the highest number of fungal colonies as urban. These developed areas have moderate to high vehicular traffic. The work provides evidence of asthma-related fungi in the area, although this alone does not account for the observed high asthma prevalence.

"This work revealed the presence of fungal allergens that can be potential asthma triggers and establishes a rationale for future research in this area," the researchers conclude.
