Analysis of Airborne Fungal Spores in Lima, Perú (2021–2024): Seven Clinically Important Spore Types

Detalhes bibliográficos
Resumo:Fungal spore calendars help illustrate the abundance and distribution of spores throughout the year, enabling clinicians and patients to predict and treat allergic symptoms based on spore presence and concentration. This three-year study (2021–2024) established the first fungal spore calendar for the most clinically important spore types in Lima, Perú: Alternaria, Cladosporium, Nigrospora, Curvularia, Drechslera, Fusarium, and Stemphylium. Air sampling was performed using a Burkard volumetric spore trap placed on the rooftop of SANNA Clínica el Golf in San Isidro, Lima. Cladosporium was the most abundant (37,945 spores/m3), followed by Nigrospora (11,558), Curvularia (3946), Fusarium (2454), Alternaria (2138), Drechslera (1850), and Stemphylium (201). The highest concentrations of Alternaria, Nigrospora, Curvularia, and Drechslera were recorded in 2023–2024, with seasonal peaks mainly during spring/summer. Meteorological correlations showed that Alternaria, Cladosporium, Nigrospora, and Curvularia were positively correlated with temperature while Drechslera had a negative correlation. Cladosporium, Curvularia, Fusarium, and Stemphylium were negatively correlated with relative humidity, while other types showed a mix of both positive and negative responses or inverse responses. These two meteorological parameters are likely the main influences on spore concentrations; however, other factors may include other meteorological parameters. Cladosporium correlated positively with southwesterly winds, and negatively with northwesterly, winds, and Curvularia was positively correlated with northeasterly winds.
