An Egyptian isolate of Streptomyces afghanensis was examined for the production of antiviral metabolites. Concentrated broth exudates of this microorganism were tested against tobacco mosaic virus (TMV), tomato mosaic virus (ToMV) and potato virus X (PVX) infecting Nicotiana tabacum L. cv. White Burley. Both concentrated metabolites and their acetone extract inhibited local lesion development of the tested viruses. In all cases, maximum antiviral effect was observed 2 hr after infection. The ultrafiltrate of broth culture reduced the number of local PVX lesions produced on the challenged half leaves in the case of later applications.
对一株来自埃及的阿富汗链霉菌进行了抗病毒代谢产物生产的研究。用该微生物的浓缩肉汤渗出物对感染烟草品种白肋烟的烟草花叶病毒（TMV）、番茄花叶病毒（ToMV）和马铃薯X病毒（PVX）进行了测试。浓缩代谢产物及其丙酮提取物均抑制了受试病毒的局部病斑形成。在所有情况下，感染后2小时观察到最大抗病毒效果。对于较晚施用的情况，肉汤培养物的超滤物减少了在受挑战半叶上产生的局部PVX病斑数量。
