Botulism, well known for centuries, continues to preoccupy the Public Health authorities, food and agricultural industries. In its oldest form it results from ingestion of food containing botulinum toxin. To correctly evaluate the incidence of botulism it is fundamental to know the distribution of botulinum toxin-producing clostridia (Clostridium botulinum, C. baratii, C. butyricum and C. argentinense) in nature, specially in the soil, its main reservoir. In our country, this study has been carried out in a partial way. With the aim to contribute to such knowledge, 240 soil samples from Entre Ríos province were examined for C. botulinum and 35 (14.6%) samples resulted positive.
肉毒中毒已为人所知数百年，仍然让公共卫生当局、食品和农业行业忧心不已。其最古老的形式是因摄入含有肉毒杆菌毒素的食物所致。要正确评估肉毒中毒的发病率，关键是要了解自然界中产生肉毒杆菌毒素的梭状芽孢杆菌（肉毒梭菌、巴氏梭菌、丁酸梭菌和阿根廷梭菌）的分布情况，尤其是在其主要储存库土壤中的分布。在我国，这项研究只是部分开展。为了有助于获取此类知识，对恩特雷里奥斯省的240份土壤样本进行了肉毒梭菌检测，其中35份（14.6%）样本呈阳性。
