美科学家在孟山都引入中国的转基因作物中发现令人类绝种的新型病原体
实验室试验证实这种微生物经历自然流产和不孕症种类繁多牲畜中存在。在进行研究的初步结果也得以在临床中重现这样的流产。这些病原体有可能解释美国的牛、奶牛、猪和马养殖中过去数年不断上升的不孕和自然流产的原因。最近的一些报告提出小母牛不孕症超过20％，牛的自然流产则高达45％以上。 例如，喂食小麦的1000头怀孕的母牛有450头发生自然流产。同一时期，同一牛群喂食干草的另外1000头母牛则没有任何流产的情况。喂食怀孕母牛的小麦中确认有高浓度的上述病原体，它们种植时治理野草中使用了草甘膦除草剂。 总之，鉴于抗草甘磷作物检测出了高浓度的这种新的动物病原体，它与植物和动物疾病的关联性，已经达到流行病比率的程度，我们要求美国农业部参与一项多机构的调查，并且立即暂停对抗除草剂转基因作物的控制放松，直至草甘膦除草剂和/或抗草甘膦转基因作物与它们对农作物和畜牧生产和人类健康构成威胁的因果关系可以排除为止。 迫切需要研究草甘膦的使用的副作用是否可能促进了这种病原体的生长，或允许它们对植物和动物宿主造成更大的削弱性伤害。有良好的记录证明草甘膦促进土壤中病原体的发展以及知道它与40多种植物疾病的增加有牵连；它通过螯合对植物维持生命必须的营养物，破坏了植物的防御系统；从而也降低了动物对饲料营养素的生物利用度，这反过来又可以导致动物机能失调。为了正确地评估这些因素，我们要求查阅美国农业部有关的数据。 我本人对植物的病原体已经进行了50多年研究。我们现在看到一个植物和动物疾病和病症日益严重的前所未有的趋势。这种病原体可能对认识和解决这个问题有所帮助。它值得立即关注和投入大量资源，以避免我们的关键性的农业基础设施发生普遍性的崩溃。 诚挚的， 上校（退休）顿·M·胡伯 （美国）普渡大学名誉教授 APS协调员，美国农业部国家植物疾病恢复系统（NPDES） 信件原文： Dear Secretary Vilsack: A team of senior plant and animal scientists have recently brought to my attention the discovery of an electron microscopic pathogen that appears to significantly impact the health of plants, animals, and probably human beings. Based on a review of the data, it is widespread, very serious, and is in much higher concentrations in Roundup Ready (RR) soybeans and corn—suggesting a link with the RR gene or more likely the presence of Roundup. This organismappears NEW to science! This is highly sensitive information that could result in a collapse of US soy and corn export markets and significant disruption of domestic food and feed supplies. On the other hand, this new organism may already be responsible for significant harm (see below). My colleagues and I therefore moving our investigation forward with speed and discretion, and seek assistance from the USDA and other entities to identify the pathogen’s source, prevalence,implications, and remedies. We informing the USDA of our findings at this early stage, specifically due to your pending decision regarding approval of RR alfalfa. Naturally, if either the RR gene or Roundup itself is a promoter or co-factor of this pathogen, then such approval could be a calamity. Based on the current evidence, the only reasonable action at this time would be to delay deregulation at least until sufficient data has exonerated the RR system, if it does. For the past 40 years, I have been a scientist in the professional and military agencies that evaluate and prep for natural and manmade biological threats, including germ warf and disease outbreaks. Based on this experience, I believe the threat we facing from this pathogen is unique and of a high risk status. In layman’s terms, it should be treated as an emergency. A diverse set of researchers working on this problem have contributed various pieces of the puzzle, which together presents the following disturbing scenario: Unique Physical Properties This previously unknown organism is only visible under an electron microscope (36,000X), with an approximate size range equal to a medium size virus. It is able to reproduce and appears to be a micro-fungal-like organism. If so, it would be the first such micro-fungus ever identified. There is strong evidence that this infectious agent promotes diseases of both plants and mammals, which is very r. It is found in high concentrations in Roundup Ready soybean meal and corn, distillers meal, fermentation feed products, pig stomach contents, and pig and cattle placentas. The organism is prolific in plants infected with two pervasive diseases that driving down yields and farmer income—sudden death syndrome (SDS) in soy, and Goss’ wilt in corn. The pathogen is also found in the fungal causative agent of SDS (Fusarium solani fsp glycines). Laboratory tests have confirmed the presence of this organism in a wide variety of livestock that have experienced spontaneous abortions and infertility. Preliminary results from ongoing research have also been able to reproduce abortions in a clinical setting. The pathogen may explain the escalating frequency of infertility and spontaneous abortions over the past few years in US cattle, dairy, swine, and horse operations. These include recent reports of infertility rates in dairy heifers of over 20%, and spontaneous abortions in cattle as high as 45%. For example, 450 of 1,000 pregnant heifers fed wheatlege experienced spontaneous abortions. Over the same period, another 1,000 heifers from the same herd that were raised on hay had no abortions. High concentrations of the pathogen were confirmed on the wheatlege, which likely had been under weed management using glyphosate. In summary, because of the high titer of this new animal pathogen in Roundup Ready crops, and its association with plant and animal diseases that reaching epidemic proportions, we request USDA’s participation in a multi-agency investigation, and an immediate moratorium on the deregulation of RR crops until the causal/predisposing relationship with glyphosate and/or RR plants can be ruled out as a threat to crop and animal production and human health. It is urgent to examine whether the side-effects of glyphosate use may have facilitated the growth of this pathogen, or allowed it to cause greater harm to weakened plant and animal hosts. It is well-documented that glyphosate promotes soil pathogens and is already implicated with the increase of more than 40 plant diseases; it dismantles plant defenses by chelating vital nutrients; and it reduces the bioavailability of nutrients in feed, which in turn can cause animal disorders. To properly evaluate these factors, we request access to the relevant USDA data. I have studied plant pathogens for more than 50 years. We now seeing an unprecedented trend of increasing plant and animal diseases and disorders. This pathogen may be instrumental to understanding and solving this problem. It deserves immediate attention with significant resources to avoid a general collapse of our critical agricultural infrastructure. Sincerely, COL (Ret.) Don M.
