“…Tarlo et al (1979) found Ganoderma basidiospores to be the most prevalent fungal airborne fungal spores in Canada. Studies from New Zealand also reported that Ganoderma basidiospores constituted a major component of the airspora (Hasnain et al, 1984(Hasnain et al, , 1985Cutten et al, 1988;Hasnain, 1993). Ganoderma has been reported as an important and prevalent fungal airspora component worldwide (Halwagy, 1994;Hasnain, 1993;Hasnain et al, 1984Hasnain et al, , 1985Herxheimer et al, 1969;Lehrer et al, 1986Lehrer et al, , 1994Levetin, 1990Levetin, , 1991Li & Kendrick, 1994Mitakakis & Guest, 2001;Stępalska & Wołek, 2005).…”

The investigation of airborne fungal spore concentrations was carried out in Szczecin, Poland between 2004 and 2006. The objective of the studies was to determine a seasonal variation in concentrations of selected fungal spore types due to meteorological parameters. The presence of spores of ten taxa: Cladosporium, Ganoderma, Alternaria, Epicoccum, Didymella, Torula, Dreschlera-type, Polythrincium, Stemphylium and Pithomyces was recorded in Szczecin using a volumetric method (Hirst type). Fungal spores were present in the air in large numbers in summer. The highest concentrations were noted in June, July and August. The peak period was recorded in August for most of the studied spore types: Ganoderma, Alternaria, Epicoccum, Dreschlera-type, Polythrincium and Stemphylium. Cladosporium and Didymella spores reached their highest concentrations in July while concentrations of Torula were highest in May and Pithomyces in September. Multiple regression analysis was performed for three fungal seasons: 2004, 2005, and 2006. Spore concentrations were positively correlated with minimum temperature for seven spore types in 2004, for five spore types in 2005, and for eight spore types in 2006 (significance level of a50.05). Some spore types are also significantly correlation among their concentrations, pressure, relative humidity and rain. Minimum temperature appeared to be the most influential factor for most spore types.

“…Sabariego et al (2004) observaron una relación positiva entre la concentración de conidios de Cladosporium y el promedio de las temperaturas máximas y mínimas. Hasnain (1993) encontró una fuerte correlación entre la temperatura máxima y la concentración de Cladosporium. Sánchez & Almaguer (2014), afirman que, en La Habana, en donde la temperatura varía entre 25 °C y 30 °C y la humedad relativa se mantiene por encima del 70%, prevaleció Cladosporium.…”

“…También se ha determinado que existe una gran variación estacional en la concentración de conidios de Cladosporium, la más alta concentración ocurre durante el verano (Hasnain, 1993;Burch & Levetin, 2002;Peternel et al, 2004;Kasprzyk, 2008;Kumari et al, 2011;Grinn-Gofroń & Strzelczak, 2012). Varios factores meteorológicos como la humedad, temperatura, radiación solar, precipitación, velocidad del viento y presión atmosférica afectan la producción y dispersión conidial en Cladosporium (Sakiyan & Inceoglu, 2003;Erkara et al, 2008;Kumari et al, Cladosporium EN ATMÓSFERA DE LIMA EN RELACIÓN CON FACTORES METEOROLÓGICOS Enero -Julio 2018 __________________________________________________________________________________________ 40 2011; Zoppas et al, 2011;Grinn-Gofroń & Bosiacka, 2015).…”

ResumenEl objetivo de este estudio fue detectar el hongo alergénico Cladosporium en la atmósfera de la Plaza San Martín de Lima (Perú) y analizar la influencia de las variables meteorológicas sobre su concentración. El muestreo del aire se ha realizado utilizando un equipo de impacto volumétrico tipo Andersen de una sola etapa. Se observó que los conidios de Cladosporium estuvieron presentes en la atmósfera durante todo el período de estudio, sin embargo, las concentraciones más altas se observaron en los meses de marzo y septiembre. Se ha encontrado una correlación estadística positiva entre la concentración de conidios de Cladosporium y la velocidad del viento e índice UV. El efecto de la temperatura del aire presentó una débil correlación positiva sobre la concentración de Cladosporium a diferencia de la humedad relativa que presentó una correlación negativa. La identificación de los factores climáticos que favorecen la liberación de conidios puede mejorar significativamente los métodos actuales de prevención de la alergia, la detección temprana de infecciones en plantas o enfermedades respiratorias en humanos. Palabras clave: bioaerosol, conidios, esporas, alergia, variables climáticas. AbstractThe objective of this study was to detect the allergenic fungus Cladosporium in the atmosphere of the Plaza San Martín of Lima (Perú) and to analyze the influence of the meteorological variables on its concentration. Air sampling was performed using a one-stage Andersen type volumetric impact equipment. Cladosporium conidia are present in the atmosphere of Plaza San Martín throughout the study period, however, the highest concentrations were observed in the months of March and September. A positive statistical correlation was found between the concentration of Cladosporium conidia and the wind speed and UV index. The effect of the air temperature showed a weak positive correlation on the concentration of Cladosporium, however, the relative humidity presented a negative correlation. Identification of climatic factors favoring the release of conidia may improve current methods of allergy prevention, early detection of plant infections or respiratory diseases in humans.

“…In moderate climate most of spores occur in summer or early autumn (Kasprzyk & Worek 2006), whereas in tropical areas they are more abundant in cold seasons of the year (Hasnain 1993). Microclimate greatly influences the release and appearance of spores, what relates not only to local rainfalls or the effect of ponds, lakes and water reservoirs, but it may also relate to temperature.…”

Air is a natural environment for spores of many genera and species of fungi. Despite its small size and a significant dispersion they have a great impact on human health and different areas of our activities, such as agricultural production. The study on spores of fungi that belong to aeroplankton or bioaerosole is called aeromycology. The most frequent fungi present in the air are Cladosporium and Alternaria species. Their numbers are abundant regardless of latitude and height above the sea level and above the ground. They mostly originate from agricultural environment. Other frequently listed species of fungi, whose spores are present in the air include of Aspergillus, Penicillium, Fusarium, Sclerotinia and Ganoderma. The concentration of spores in the air strongly depends on the abundance of their formation during the studied period. This in turn relates to geobotanical region, vegetation, degree of urbanization, climatic conditions, season, current weather, wind force and direction, local microclimate, and many other factors. Changes in humidity affect the concentration of different types of fungal spores. In general they are divided to ‘dry’ (Alternaria, Cladosporium, Puccinia, Ustilago, Melampsora, Epicoccum, Drechslera) and ‘wet’ (Didymella, Fusarium, Ganoderma, Gliocladium, Leptosphaeria, Verticillium). Study of the composition of species and genera are being done using different types of spore samplers, mostly volumetric instruments. Visual identification is based on colony morphology of the fungus and the shape and size of spores. The identification at the species level is possible with molecular tools. Methods based on DNA/RNA amplification are very sensitive and accurate. They allow the identification below the species level, e.g. chemotypes, mating types or isolates with genes or alleles of interest. Aerobiological monitoring is widely used in the epidemiology of human diseases (inhalant allergies) and infections of arable crops (decision support systems for the protection of cultivated plants). Aeromycology is interconnected with such diverse areas as industrial aerobiology, bioterrorism, ecology, climatology or even speleology and cultural heritage.
