Forecasting asthma-causing fungal spores from climate
November 17, 2003The latest research into a weather phenomenon that affects UK wheat quality could have a knock-on effect in the fight against asthma.
Researchers at Harper Adams University College working with MAARA, the Midlands Asthma and Allergy Research Association, and the University of Reading, believe fluctuations in air pressure, known as the North Atlantic Oscillation or NAO, may contribute to the presence of fungal spores in the air. These spores can then cause summer asthma.
The fungi that release these spores, such as Cladosporium, grow on plants, including wheat, in the summer and release spores into the air. Wet weather causes the wheat grains to sprout, which makes the grains unsuitable for bread making, devalues the crop, and also reduces the number of Cladosporium spores released.
Research into the NAO during the winter was initially carried out to monitor its effect on summer rainfall levels in the UK and provide an early prediction about whether or not the wheat grain will have sprouted by the time it is ready to harvest.
Further research, due to be published in the International Journal of Biometeorology in December, has now revealed that the number of Cladosporium spores released during summer may be linked to the NAO.
Dr Peter Kettlewell said: "Our results show that some types of spores causing asthma increase as the NAO rises, and we are currently working on developing an early warning of a high spore year."

Microlife PF 100 Peak Flow Meter for Spirometry with FEV1 by Microlife This device is used to measure Peak Expiratory Flow (PEF) and Forced Expiratory Volume in 1-second (FEV1) in both children and adults. PEF is the fastest speed air can be blown out of the lungs after inhalation. FEV1 measures the volume after exhaling in 1-second. Peak Flow (PEF) and Forced Expiratory Volume in 1-second (FEV1) measurements can tell how well lungs are breathing by monitoring airflow. Doctors can have patients monitor changes in airflow and record the results. The automatic memory stores and provides easy access to the last 240 readings along with the time and date. |
