Even though the presence of Curvularia conidia in the tropical air and the role in respiratory allergy symptoms or plant diseases incidence has been reported, traditional aerobiological investigations usually do not consider their profound study. An aeromycological study of the Curvularia propagules in Havana was conducted during the years 2017 and 2018. Monitoring was carried out by means of volumetric viable and non-viable methodologies. Three types of microscopically identifiable airborne spores (Lunata, Geniculata and Maculans) were identified, according to their distinctive features (conidium shape, pigmentation, number and position of the septa), defined by optical microscopy with 400 × magnification. The spores of Curvularia showed prevalence during rainy months and were predominantly abundant through the daytime. The annual distribution showed the prevalence of the Lunata type, with a diurnal pattern and corroborated through the isolated species since all belonged to this morphological group. The average temperature and relative humidity, as well as the precipitations, correlated positively with the concentrations. The wind speed showed a negative correlation, which indicates that the climatic conditions of the Havana influence the aerobiological dynamics of airborne Curvularia propagules.

古巴哈瓦那大气中空气中弯曲菌繁殖体的评估

尽管已经报道了热带空气中存在弯孢霉分生孢子以及在呼吸道过敏症状或植物疾病发病率中的作用，但传统的空气生物学调查通常不考虑他们的深入研究。2017 年和 2018 年对哈瓦那弯孢菌繁殖体进行了空气真菌学研究。监测是通过体积活和非活方法进行的。根据其独特的特征（分生孢子形状、色素沉着、隔膜的数量和位置），通过 400 倍放大倍数的光学显微镜确定了三种显微镜下可识别的空气传播孢子（Lunata、Geniculata 和 Maculans）。Curvularia 的孢子在雨季流行，并且主要在白天大量存在。年度分布显示 Lunata 类型的流行，具有昼夜模式，并通过孤立的物种得到证实，因为它们都属于该形态组。平均温度和相对湿度以及降水量与浓度呈正相关。风速呈负相关，表明哈瓦那的气候条件影响了空气中弯曲菌繁殖体的空气生物学动力学。
