We have studied the occurrence of Alternaria, a genus of allergenic interest in the indoor atmosphere of 14 homes in Córdoba throughout 1984. The sampling was carried out by sedimentation on a broad-spectrum mycological culture medium (2% Agar-Malt extract) in Petri dishes. Samples were collected every fortnight in 14 homes (three dishes per home were exposed in the following rooms, namely the kitchen, the toilet and the bedroom, for 20 minutes) located in different areas of the city and as much as possible representing the various physical conditions found. An overall of 727 Alternaria colonies belonging to six species (A. consortiale, A. crassa, A. dendritica, A. japonica, A. tenuis and A. tenuissima) were detected. Some of them were proven allergenics. They accounted for 5.2% of all fungal colonies found indoors. A. tenuis was by far the most frequently found species, followed by A. tenuissima (second in number) and A. consortiale (the most cosmopolitan) as they were the only species found in all 14 homes. On the other hand, A. crassa was the least frequent of all species collected. We have also determined the general variation of Alternaria and that of the different species found indoors throughout the year, finding a trend with the appearance of peaks towards spring and early summer, especially in June.
1984年全年，我们对科尔多瓦14户家庭室内空气中具有致敏作用的链格孢属真菌的出现情况进行了研究。采样是通过将其沉降在培养皿中的广谱真菌培养基（2%麦芽提取物琼脂）上进行的。每两周在该市不同区域的14户家庭中进行采样（每户家庭在厨房、卫生间和卧室等房间放置三个培养皿，暴露20分钟），并尽可能代表所发现的各种物理条件。共检测到属于六个物种（共生链格孢、粗链格孢、枝状链格孢、日本链格孢、细链格孢和极细链格孢）的727个链格孢菌落。其中一些已被证实具有致敏性。它们占室内发现的所有真菌菌落的5.2%。细链格孢是迄今为止最常发现的物种，其次是极细链格孢（数量第二）和共生链格孢（分布最广），因为它们是在所有14户家庭中都能找到的仅有的物种。另一方面，粗链格孢是所有采集物种中出现频率最低的。我们还确定了全年室内链格孢属真菌及其不同物种的总体变化情况，发现有在春季和初夏，尤其是6月出现峰值的趋势。
