摘要： 为了防范恐怖分子使用“生物武器”发动的袭击，日本政府计划“派遣”小鱼到供水系统中，希望这些“侦察兵”可以及早“发现”污染事件。

摘要： Human V gamma 9V delta 2 T cells play a crucial role in early immune response to intracellular pathogens. Moreover, in brucellosis, these cells are drastically increased in the peripheral blood of patients during the acute phase of infection. In vitro, V gamma 9V delta 2 T cells are capable of inhibiting Brucella growth and development through a combination of mechanisms: 1) cytotoxicity, 2) macrophage activation and bactericidal activity through cytokine and chemokine secretion, and 3) antibacterial effects. We previously described that antibacterial factors were found in supernatants from activated V gamma 9V delta 2 T cells. In this study, we show that V gamma 9V delta 2 T cells express the human cathelicidin hCAP18 and its mature form, known as LL-37, is released upon activation of V gamma 9V delta 2 T cells. We also show that LL-37 has an antibacterial effect on Brucella suis. Overall, our results demonstrate that LL-37 is a soluble factor responsible for a part of the bactericidal activity of V gamma 9V delta 2 T cells.

摘要： Brucella has traditionally been considered a biological weapon. It was the subject of extensive offensive research in the past, and still belongs to category B pathogens on most lists. Its propensity for airborne transmission and induction of chronic debilitating disease requiring combined antibiotic regimens for treatment, its abundance around the world and its vague clinical characteristics defying rapid clinical diagnosis are some of the characteristics that apply to the pathogen's weapons potential. Yet minimal mortality, availability of treatment options, protracted inoculation period and the emergence of new, more virulent potential weapons means that its inclusion among agents of bioterrorism is nowadays mainly of historical significance. Nevertheless, in the interest of literacy and of avoiding panic, physicians and the public both should be aware of the most common zoonosis worldwide.

摘要： Next month, Biological Weapons Convention (BWC) member states will gather fora review conference five years after a previous meeting dissolved amid acrimony. So far, the signsare that countries participating in November's BWC review meeting will avoid a repeat of late 2001'sscarring experience. Since 2002, a modest work program has helped to rebuild a measure ofconfidence in the BWC process.

摘要： 眼下，正值防治夏秋蔬菜病虫害的高峰期。在云南元谋县无公害蔬菜种植园区，却出现了与往年不同的景象：菜农们不是忙着给蔬菜喷洒农药，而是往蔬菜田里释放蚜茧蜂和丽蚜小蜂蛹这些“生物武器”。这是全县实施生物防治战略，“以虫治虫”防治病虫害，进一步提升元谋无公害蔬菜品质的新举措。
