As aerosols are important sources of infection, care should be taken to reduce the extent of their formation and dispersion Hazardous aerosols can be generated by many laboratory operations, e.g. blending, mixing, grinding, shaking, stirring, sonicating and centrifuging of infectious materials. Even when safe equipment is used, it is best to carry out these operations in an approved biological safety cabinet whenever possible

A basic knowledge of disinfection and sterilization is crucial for biosafety in the laboratory. Since heavily soiled items cannot promptly be disinfected or sterilized, it is equally important to understand the fundamentals of cleaning prior to disinfection (precleaning). In this regard, the following general principles apply to all known classes of microbial pathogens

Human error, poor laboratory techniques and misuse of equipment cause the majority of laboratory injuries and work-related infections. This chapter provides a compendium of technical methods that are designed to avoid or minimize the most commonly reported problems of this nature

The Laboratory biosafety manual has in the past focused on traditional biosafety guidance for laboratories. The manual emphasizes the use of good microbiological work practices, appropriate containment equipment, proper facility design, operation and maintenance, and administrative considerations to minimize the risk of worker injury or illness. In following these recommendations, the risk to the environment and surrounding community-at-large is also minimized

Chapter 6. Laboratory animal facilities Those who use animals for experimental and diagnostic purposes have a moral obligation to take every care to avoid causing them unnecessary pain or suffering. The animals must be provided with comfortable, hygienic housing and adequate wholesome food and water At the end of the experiment they must be dealt with in a humane manner

The employing authority, through the la boratory director, is responsible for ensuring that there is adequate surveillance of the health of laboratory personnel. The objective of such surveillance is to monitor for occupationally acquired diseases Appropriate activities to achieve these objectives are:

Brucellosis is an infectious disease caused by the bacteria of the genus Brucella These bacteria are primarily passed among animals, and they cause disease in many different vertebrates Various Brucella species affect sheep, goats, cattle, deer, elk, pigs, dogs, and several other animals Humans become infected by coming in contact witl animals or animal products that are contaminated with these bacteria

当我们伴随着 Windows2000和ASP3.0进入21世纪时,发现微软在企业应用程序开发方面 扩展和改进了对开发人员来说非常有用的工具和技术。在前面两章中讨论了如何使用ASP和 com构建b应用程序。通过使用功能强大的IS,使用所选择的程序语言开发COM组件,使 b应用程序远远超越仅使用ASP脚本创建互相链接的简单网页的水平。可以开发安全高效的 基于组件的可扩展应用程序,以此来支持面向数以千计用户的业务处理
