    Description: As we enter the new millennium the world is still facing the challenge of responding to the AIDS pandemic. A new report from the Joint United Nations Programme on HIV/AIDS presents the latest statistics on prevalence, spread, and impact of the disease. In their Perspective, Schwartlander and his colleagues discuss the newly released statistics and the strategies needed to combat the further spread of HIV/AIDS and to reduce prevalence in the most severely affected countries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schwartlander, B -- Garnett, G -- Walker, N -- Anderson, R -- New York, N.Y. -- Science. 2000 Jul 7;289(5476):64-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UNAIDS, 20 Avenue Appia, Geneva 27 CH-1211, Switzerland. schwartlanderb@unaids.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10928930" target="_blank"〉PubMed〈/a〉

    Description: Legionella pneumophila, the bacterial agent of legionnaires' disease, replicates intracellularly within a specialized vacuole of mammalian and protozoan host cells. Little is known about the specialized vacuole except that the Icm/Dot type IV secretion system is essential for its formation and maintenance. The Legionella genome database contains two open reading frames encoding polypeptides (LepA and LepB) with predicted coiled-coil regions and weak homology to SNAREs; these are delivered to host cells by an Icm/Dot-dependent mechanism. Analysis of mutant strains suggests that the Lep proteins may enable the Legionella to commandeer a protozoan exocytic pathway for dissemination of the pathogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, John -- de Felipe, Karim Suwwan -- Clarke, Margaret -- Lu, Hao -- Anderson, O Roger -- Segal, Gil -- Shuman, Howard A -- NIH-R01 AI23549/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 27;303(5662):1358-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, College of Physicians and Surgeons, Columbia University, 701 West 168th Street, New York, NY 10032, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14988561" target="_blank"〉PubMed〈/a〉
