Activities to increase provider awareness of early syphilis in men who have sex with men in 8 cities, 2000-2004.

OBJECTIVE: Describe provider awareness campaigns undertaken in response to syphilis epidemics among men who have sex with men (MSM). METHODS: Descriptive data from 8 cities facing MSM syphilis epidemics was compiled. RESULTS: Provider awareness efforts included medical alerts, provider visits, lectures to providers on symptom recognition and treatment, and ongoing provision of syphilis and other sexually transmitted diseases (STD) morbidity information through mailings, visits, and e-mail communications. Increases in private provider reporting of syphilis cases followed provider visits in Atlanta and overall provider education efforts in New York City. Decreases in reporting delays and increases in physician calls to the STD program were reported in San Francisco following provider syphilis lectures. Increases in provider participation in community action meetings followed provider awareness efforts in Houston, Chicago, and Miami. CONCLUSIONS: Various methods were used to increase provider awareness of syphilis in these 8 cities. The cost and impact of these activities merits more formal evaluation to determine their contribution to syphilis control in MSM.

Microbial diversity of extant stromatolites in the hypersaline marine environment of Shark Bay, Australia.

Stromatolites have been present on Earth, at various levels of distribution and diversity, for more than 3 billion years. Today, the best examples of stromatolites forming in hypersaline marine environments are in Hamelin Pool at Shark Bay, Western Australia. Despite their evolutionary significance, little is known about their associated microbial communities. Using a polyphasic approach of culture-dependent and culture-independent methods, we report the discovery of a wide range of microorganisms associated with these biosedimentary structures. There are no comparable reports combining these methodologies in the survey of cyanobacteria, bacteria, and archaea in marine stromatolites. The community was characterized by organisms of the cyanobacterial genera Synechococcus, Xenococcus, Microcoleus, Leptolyngbya, Plectonema, Symploca, Cyanothece, Pleurocapsa and Nostoc. We also report the discovery of potentially free-living Prochloron. The other eubacterial isolates and clones clustered into seven phylogenetic groups: OP9, OP10, Marine A group, Proteobacteria, Low G+C Gram-positive, Planctomycetes and Acidobacteria. We also demonstrate the presence of sequences corresponding to members of halophilic archaea of the divisions Euryarchaeota and Crenarchaeota and methanogenic archaea of the order Methanosarcinales. This is the first report of such archaeal diversity from this environment. This study provides a better understanding of the microbial community associated with these living rocks.
