Hyperhydricity, or vitrification, is a physiological malformation affecting tissue culture-generated plants. This malformation is associated with excessive hydration and poor lignification and results in poor regeneration of plants. We have tested hyperhydricity prevention in oregano by several nonspecific polysaccharide-producing rhizosphere bacteria.(More)
The polymerase chain reaction (PCR) was used in an attempt to detect Bacteroides fragilis by amplifying a segment of the gene encoding B. fragilis neuraminidase. Forty-five reference strains representing 45 species and 113 clinical isolates were tested. Only B. fragilis was PCR positive, except for Bacteroides merdae ATCC 43184, which gave a band by(More)
The present article describes the recent status of research on anaerobes in Japan by reviewing publications from the last few years in the Japanese Journal of the Association for Anaerobic Infection Research. Most studies were categorized into clinical infection, susceptibility and resistance mechanisms, epidemiology and typing systems, and pathogenesis and(More)
Immunoblotting and pulsed-field gel electrophoresis of Clostridium difficile isolates were employed to differentiate reinfection by a newly acquired strain from relapse by an original strain in a 10-year-old patient with four episodes of C. difficile-associated colitis. Immunoblot typing demonstrated subserogroup K-1 of serogroup K for the first and second(More)
to the final endpoint was not observed for the antimicrobial agents Actinomyces species and Propionibacterium propionicus are tested in this study. well-known causes of actinomycosis. Because histological examiBecause of differences in the experimental conditions, the nation plays a pivotal role in the recognition of actinomycosis, NCCLS (National Committee(More)
The in vitro antibacterial activities of the newly developed 7a-methoxy cephalosporins and 7Imethoxyiminoacetamido cephalosporins against 67 clinical isolates of Bacteroides fragilis and their resistance to the hydrolytic action of a ,-lactamase produced by B. fragilis were simultaneously compared. The minimal inhibitory concentrations that inhibited 90% of(More)
The activity of FK037, a new parenteral cephalosporin, was compared with those of cefpirome, ceftazidime, and flomoxef against 322 recent clinical isolates of anaerobic bacteria. A fastidious facultative anaerobe, GardnereUa vaginalis, was also studied. FK037 inhibited 90% of isolates of Peptostreptococcus anaerobius, Peptostreptococcus asaccharolyticus,(More)
