We studied strains of an unusual streptococcus that superficially resembles Streptococcus sanguis but has fibrils that are arranged in lateral tufts. These strains were originally isolated from human throats and oral cavities and have been referred to previously as "Streptococcus sanguis I," the "CR

Isolates of Fusobacterium that differ from type strains of various fusobacterial species with respect to DNA sequence, cellular fatty acid composition, and biochemical activity, were obtained from periodontitis lesions in a patient with insulin-dependent diabetes mellitus. These isolates have the

In 2007, a new bacterial disease was observed in greenhouse-cultivated cherry tomatoes in Cheorwon and Iksan provinces, Korea. The disease caused severe wilt of tomatoes (Solanum lycopersicum cv. Koko). Infected young petioles were curled downward. Margins of the leaves rolled upward and whole

The relationship between oral hygiene and oral Group D streptococcal carrier status was examined in two groups of dental clinic patients. Eighteen medically-physically compromised and 20 periodontitis patients were selected for study. Oral hygiene status was assessed and the prevalence of oral Group

Pathogenic properties of the natural isolate of Shewanella algae from the coelomic fluid of the sea cucumber Apostichopus japonicus (Peter the Great Bay, Sea of Japan) were investigated. The isolate had oxydative metabolism, was positive for ornithine decarboxylase, cytochrome oxidase, catalase,

A total of 113 pure cultures of Streptococcus sanguis were obtained from dental plaque samples of 64 subjects. All isolates synthesized glucan from sucrose, elaborated peroxide, and were alpha-hemolytic. Two biotypes and four serotypes were differentiated within the species. Biotype A (95 isolates)
