The aim of this study was to analyze the distribution and phenotypic properties of the indigenous streptococci in chimpanzee (Pan troglodytes) oral cavities. Eleven chimpanzees (aged from 9 to 44 years, mean ± SD, 26.9 ± 12.6 years) in the Primate Research Institute of Kyoto University were enrolled in this research and brushing bacterial samples collected from them. Streptococci were isolated ...

BACKGROUND The soft tissue around dental implants forms a barrier between the oral environment and the peri-implant bone and a crucial factor for long-term success of therapy is development of a good abutment/soft-tissue seal. Sol-gel derived nanoporous TiO2 coatings have been shown to enhance soft-tissue attachment but their effect on adhesion and biofilm formation by oral bacteria is unknown....

Transposon mutagenesis and single-gene deletion are two methods applied in genome-wide gene knockout in bacteria (1,2). Although transposon mutagenesis is less time consuming, less costly, and does not require completed genome information, there are two weaknesses in this method: (1) the possibility of a disparate mutants in the mixed mutant library that counter-selects mutants with decreased c...

We report the first case of infective endocarditis following urinary tract infection (UTI) caused by Globicatella sanguinis in an 87-year-old Japanese woman with recurrent episodes of UTI. We identified the pathogen using the Rapid ID32 Strep system. Accurate identification of this infection is important and essential for the effective antimicrobial coverage to this pathogen.

Single-strand conformation polymorphism (SSCP) analysis is widely used to prescreen mutations in p53 gene. However, standardization of SSCP to detect p53 mutations has rarely been pursued so far. We have developed complete conditions for a temperature-controlled nonradioactive SSCP for mutation detection in amplified p53 exons 4-8, where mutations frequently occur in human tumors. Easily obtain...

Globicatella sanguinis is a rare isolate in clinical samples. We present a case of meningitis in a 70-year-old male patient after a head injury operation. Three consecutive cerebrospinal fluid samples obtained from the patient identified Globicatella sanguinis based on morphology, biochemical profile, and Vitek-2 identification. The patient recovered after antibiotic treatment with vancomycin. ...
