RESUMEN
A strategic multilateral dialogue related to biosecurity risks in Southeast Asia, established in 2014, now includes participants from Singapore, Malaysia, Indonesia, Thailand, Philippines, and the United States. This dialogue is conducted at the nonministerial level, enabling participants to engage without the constraints of operating in their official capacities. Participants reflect on mechanisms to detect, mitigate, and respond to biosecurity risks and highlight biosecurity issues for national leadership. Participants have also identified factors to improve regional and global biosecurity, including improved engagement and collaboration across relevant ministries and agencies, sustainable funding for biosecurity programs, enhanced information sharing for communicable diseases, and increased engagement in international biosecurity forums.

INTRODUCTION: Laboratory biosecurity is of continuously growing interest due to increasing concerns about deliberate misuse of biological materials and emerging biological risks. These risks continue to be magnified by globalization, the rapid pace of scientific development, and dual-use technologies. Worldwide laboratory capacities are expanding, which calls for concrete actions to improve laboratory biosafety and biosecurity practices to protect researchers and the community. Hence, laboratories require comprehensive biorisk management programs to minimize the risk of accidental and deliberate release of infectious biological materials. OBJECTIVE: Malaysia has prioritized the concern of national biosecurity and aims to consolidate laboratory biosecurity performance to detect and prevent the deliberate release of biological agents. METHODS: Two 3-day workshops were organized over the course of four months in which Malaysia collaborated with The Netherlands. This bilateral engagement aimed to integrate biosecurity practices in their national biorisk management programs, and resulted into a comprehensive biosecurity checklist for laboratory assessment and monitoring. RESULTS: This biosecurity checklist is based on Malaysian and Dutch expert opinions and national and international guidelines and regulations. The biosecurity checklist is a survey-driven tool that consists of a set of concrete questions for each key biosecurity area, which are discussion points for assessment. CONCLUSION: We display a practical biosecurity checklist for laboratory assessment and monitoring. Although the presented checklist was the template for the specific Malaysia checklist, it could serve as a template for other countries.
RESUMEN
A method was developed for the measurement of the bacterial particle conductivity, based on the measurement of the conductivity of a bacterial cell suspension sigma(s) and the suspending medium sigma(m). A line plotted through sigma(s) - sigma(m) versus sigma(m) crosses the x-axis at sigma(m) = sigma(p), independent of the bacterial cell concentration. The method does not require anything more complex than a centrifuge and a conductivity meter. Knowledge of the bacterial particle conductivity is of importance in, for example, the dielectrophoretic separation, manipulation and trapping of bacterial cells, as well as the study of their physiological state.
