This article presents the results of a survey of 99 practitioners that explored their attitudes related to the conflicting priorities of maintaining the principles of confidentiality, versus exercising one's duty to warn someone of danger. Social work practitioners face this dilemma in working with individuals who have HIV disease. When clients let workers know that they are engaging in unsafe sexual practices, and have not warned their partner of their HIV+ status, Practitioners are in a bind. Results show deep ambivalence in attitudes and actions. Discussion focuses on the dilemmas involved, and presents recommendations for practice.

Growth of Vibrio parahaemolyticus on the surfaces of solid media induces formation of a specialized bacterium called the swarmer cell. Differentiation to this cell is controlled by an information transduction mechanism which couples perception of signals specific for life on a surface to expression of genes encoding the swarmer cell phenotype. A variety of genetic tools used to analyze surface sensing in V. parahaemolyticus are described. A summary is given of what has been learned about the signals and sensors controlling differentiation and other possible genetic mechanisms for adaptation to growth on a surface or biofilm habitat are discussed.
