1·Aflatoxins, a group of toxins structurally related to secondary metabolites are produced by some fungal strains.
黄曲霉毒素是由某些真菌产毒菌株产生的次生代谢产物。
2·Methods:The fungal strains were collected and identified, and the history of antibiotic administration was reviewed.
方法：采用菌种收集、鉴定，回顾以往的用药史。
3·Results: 450 cases of patients with a total of isolated strains of 687, including the Gram-negative bacteria 356 (51.8%), Gram positive cocas 298 (43.4%), Fungal 33 (4.8%);
结果：本组450例患者总计分离出菌株687株，此中革兰阴性杆菌356株（51.8％），革兰阳性球菌298株（43.4％），真菌33株（4.8％）；
4·The aflatoxins are second fungal metabolites with highly toxic and carcinogenic properties produced by some strains of A. flavus and A. paraticus which are attented by all countries in world.
黄曲霉毒素主要是由黄曲霉和寄生曲霉产生的次级代谢产物，具有致癌、致畸、致细胞突变的“三致”作用，一直都受到各国的关注；
