Hirst spore trap
WebbA Hirst spore trap can be used to sample air throughout a 24 hour period to collect fungal spores (7). Clinical Relevance. The allergic conditions that may be caused by Phoma betae can vary. Webb29 aug. 2024 · on the Hirst spore trap (provided with a suction pump) [2,5,10,11]. The efficiencies of volumetric samplers are generally high; however, they depend on particle size, and wind velocity [11]. Pollen analysis is then achieved by microscopic identification, which demands expert knowledge and is time consuming [12–14].

WebbBackground. The Rotorod Sampler and Burkard spore trap are air-sampling instruments commonly used by allergists in the United States. Although both devices are volumetric, their principles of operation and particle recoveries differ. WebbThis design offers an isokinetically stable condition and the trap has an efficiency of approximately 97%. The performance is closely similar to the standard BURKARD …
Webbrecoveries-especially of larger particles-require precise wind orientation of the trap and are affected by continuously changing differences between air speed at the intake and in the free (ambient) stream (Watson, 1954). The Burkard-built (Hirst) spore trap is the most widely used sampler of this type, at present. Webb9 apr. 2024 · The aim of the present work was to study seasonal and site-specific patterns of airborne fungal diversity, focusing on plant pathogens.
