Nasopharyngeal carriage, antibiotic resistance and serotype distribution of Streptococcus
Abstract Background and objectives: Colonization of nasopharynx by Streptococcus Pneumoniae can lead to pneumococcal disease. This study was performed to determine the carriage rate of nasopharyngeal S.pneumoniae in adolescents and their antibiotic susceptibility and serotype prevalence in Zahedan, Iran Material and Methods: Nasopharyngeal specimens were obtained from 865 adolescents aged 10-19...
متن کاملPurification and characterization of a rhamnose-containing cell wall antigen of Streptococcus mutans B13 (serotype d).
A rhamnose-containing polysaccharide (RCP) was extracted and purified from cell walls of Streptococcus mutans B13 (serotype d) and was chemically and immunologically characterized. Walls were initially extracted with 5% trichloroacetic acid at 4 degrees C to remove the serotype antigen and were then sequentially extracted with increasing concentrations of hot acid. Extracts lacking galactose we...
متن کاملPurification and characterization of cell-associated glucosyltransferase synthesizing water-insoluble glucan from serotype c Streptococcus mutans.
Strains of Streptococcus mutans (serotypes c, e and f) were found to possess high levels of glucosyltransferase (GTase) activity, both cell-associated and in the culture medium, when grown in either sucrose-free or sucrose-containing broth media. The cell-associated GTase of S. mutans MT8148 (serotype c) was effectively extracted by treatment with 8 M-urea at 25 degrees C for 1 h. Approximately...
متن کاملComplete genome sequence of the serotype k Streptococcus mutans strain LJ23.
Streptococcus mutans is the major pathogen of dental caries and occasionally causes infective endocarditis. Here we report the complete genome sequence of serotype k S. mutans strain LJ23, which was recently isolated from the oral cavity of a Japanese patient.
