U.S.-Brazil: Workshop on Entomopathogenic Bateria; Rio de Janeiro, May 23-26, 1994

这项美国-巴西合作科学项目资助了9名美国研究人员的旅费，他们将参加一个关于内生致病菌的研讨会。10名巴西调查人员和1名哥伦比亚调查人员也将参加5月23日至26日在巴西里约热内卢奥斯瓦尔多·克鲁兹研究所举行的研讨会。合成化学杀虫剂的使用虽然非常成功，但也带来了对人类和其他非目标生物的毒性、环境污染和产生抗药性目标生物的问题。因此，人们对使用天然微生物杀虫剂的兴趣大大增加。美国科学家在细菌毒性领域处于领先地位，而巴西科学家已经开发出发酵方法，这种方法对微生物杀虫剂的大规模生产也至关重要。在确定细菌的致病特性、微生物的作用机制和大规模生产的可能性方面的合作努力将使所有有关国家受益。预计本次研讨会将产生一些新的共同感兴趣的研究合作。

Yousten 9401103 This U.S.-Brazilian Cooperative Science Program award supports travel expenses of nine U.S. researchers who will participate in a workshop on Enthomopathogenic Bacteria. Ten Brazilian and a Colombian investigator will also participate in the workshop, to be held May 23-26, at the Instituto Oswaldo Cruz, Rio de Janeiro, Brazil. The use of synthetic chemical insecticides , while highly successful, presents problems of toxicity to humans and other non-target organisms, environmental pollution,and development of resistant target organisms. As a result, interest in the use of naturally occurring microbial insecticides has increased greatly. U.S. scientists are leaders in the area of bacterial toxicity, while Brazilian scientists have developed fermentation methods that are also essential to the mass production of microbial insecticides. Collaborative efforts at defining pathogenic properties of bacteria, the mechanisms of action of the microorganisms and possibilities for mass production will benefit all countries involved. It is expected that several new research collaborations of mutual interest will emerge from this workshop.
