Skin testing of 541 men with coccidioidin was carried out in an investigation of endemism of coccidiodomycosis in the Paraguayan Chaco. In two areas where the climate is hot, dry and windy, positive reactions developed in a considerable number of the employees of an oil company who were of various racial origins, as well as among native Indians. In a third area, where rain is more plentiful and vegetation lush, only 2 per cent of 250 Indians tested had positive reaction to coccidioidin.
在巴拉圭查科地区进行的球孢子菌病地方性调查中，对541名男性进行了球孢子菌素皮肤试验。在气候炎热、干燥且多风的两个地区，一家石油公司中不同种族的大量员工以及当地印第安人都出现了阳性反应。在降雨较多、植被茂盛的第三个地区，接受检测的250名印第安人中只有2%对球孢子菌素呈阳性反应。
