Journal ArticleDOI
Short-term benefit from oral vancomycin treatment of regressive-onset autism.
Richard H. Sandler,Sydney M. Finegold,Ellen R. Bolte,Cathleen P. Buchanan,Anne P. Maxwell,Marja-Liisa Väisänen,Michael N. Nelson,Hannah M. Wexler +7 more
TL;DR: It is speculated that, in a subgroup of children, disruption of indigenous gut flora might promote colonization by one or more neurotoxin-producing bacteria, contributing, at least in part, to their autistic symptomatology.
Journal ArticleDOI
Bacteriology of Skin and Soft-Tissue Infections: Comparison of Infections in Intravenous Drug Users and Individuals with No History of Intravenous Drug Use
Paula H. Summanen,DA Talan,C. A. Strong,Maureen McTeague,Robert S. Bennion,Jesse E. Thompson,Marja-Liisa Väisänen,Gregory J. Moran,M. Winer,Sydney M. Finegold +9 more
TL;DR: The bacteriology of cutaneous or subcutaneous abscesses among intravenous drug users (IVDUs) was compared with the bacteriology in patients with no history of intravenous drugs use (non-IVDU), which yielded 173 aerobes and 131 anaerobes.
Journal ArticleDOI
In vitro activities of OPT-80 and comparator drugs against intestinal bacteria.
Sydney M. Finegold,Denise Molitoris,Marja-Liisa Väisänen,Yuli Song,Chengxu Liu,Mauricio Bolanos +5 more
TL;DR: Opt-80 showed good activity against most clostridia, staphylococci, and enterococci but streptococci , aerobic and facultative gram-negative rods, anaerobic gram- negative rods, and Clostridium ramosum were resistant.
Journal ArticleDOI
Cetobacterium somerae sp. nov. from human feces and emended description of the genus Cetobacterium.
Sydney M. Finegold,Marja-Liisa Väisänen,Denise Molitoris,Thomas J. Tomzynski,Yuli Song,Chengxu Liu,Matthew D. Collins,Paul A. Lawson +7 more
TL;DR: Phenorypic and phylogenetic studies were performed on four isolates of an unidentified gram-negative, microaerotolerant, non-spore-forming, rod-shaped bacterium isolated from the feces of children, and it was proposed that the unknown fecal bacterium be classified in the genus Cetobacterium.
Journal ArticleDOI
Anaerotruncus colihominis gen. nov., sp. nov., from human faeces
Paul A. Lawson,Yuli Song,Chengxu Liu,Denise Molitoris,Marja-Liisa Väisänen,Matthew D. Collins,Sydney M. Finegold,Sydney M. Finegold +7 more
TL;DR: It is proposed that the unknown bacterium should be classified in a novel genus as Anaerotruncus colihominis gen. nov., sp.nov, based on phylogenetic and phenotypic evidence.
