In 1873, Charles Harrison Blackley recognised pollen as the cause of hay fever and ‘‘hay asthma’’ [1]. For the first time, he collected pollen grains with a kite that had a sticky tail and then he counted them. Being affected by seasonal asthma himself, he also performed the first skin prick test on his own arm. Since then, aerobiology (from Greek á r, aēr, ‘‘air’’; bioz, bios, ‘‘life’’; and -l...

A unique agar drum sampler is described which indicates, continuously, the number of viable, bacterial particles per unit volume of air at the time and point of sampling. By selection of the timer and the sampling rate the sampler is suitable for quite a wide range of concentration and time. An impaction line of 484 in. greatly increases the capacity of this device over slit samplers and other ...

The study was carried out in the field of Aerobiology, Which deals with Microorganism, pollen grains, dust practices and other biological systems in air. This study was conducted to monitor the microbial population present in Neyveli Lignite Corporation Limited (NLC) Environment. The samples were collected on Indoor and outdoor Locations of Neyveli to measure the microbial load like, Bacteria, ...

*[email protected] 2007). In the last 50 years the cave suffered several microbiological crises (outbreak of microorganisms threatening the paintings) due to the invasion of the alga Bracteacoccus minor in 1963 (Lefèvre, 1974) and the fungus Fusarium solani in 2001 (Dupont et al., 2007). At present, the paintings are threatened by black stains produced by the fungus Ochroconis lascauxensis (M...

Wheat blast, caused by the ascomycetous fungus Pyricularia oryzae Triticum lineage (PoTl), is mainly controlled fungicide use, but resistance to main groups—sterol demethylase (DMI), quinone outside (QoI), and succinate dehydrogenase inhibitors (SDHI)—has been reported in Brazil. In order rationalize inputs (e.g., choice, timing, dose-rate, spray number, mixing/alternation) for managing wheat w...

The aerobiology of caves in Southern Spain possesses special characteristics, different from located Northern Spain. Previous studies demonstrated the influence outdoor air on north and existence two patterns, depending season. In summer there is an abundance Ascomycota, whereas winter Basidiomycota predominates, which are related to periods stagnation ventilation, respectively. presence airbor...
