Microbial Pathogenesis > 1999 > 27 > 4 > 243-252

Streptococcal toxic shock syndrome (STSS) is an illness with high mortality. To obtain clues to understanding the pathogenesis of STSS, we investigated the expression of several pathogenic factors in ten group A streptococcus (GAS) isolates from ten patients with STSS in Japan, in comparison with ten GAS isolates from children with scarlet fever. The ten scarlet fever-derived GAS isolates were equally...

Therapeutic Effect of Antimicrobial Drugs against Experimental Infections Due to Yersinia pestis in Mice

Sachiko Goto, Akiyoshi Tsuji, Teiko Murai, Minoru Nishida, more

Journal of Infection and Chemotherapy > 1998 > 4 > 1 > 16-19

Although there are effective antibacterial agents against plague, newer antibacterial agents have been developed which show more potent activity against other bacterial organisms, but have not been tested againstYersinia pestis. A strain ofYersinia pestis was selected (no. 22; National Institute of Infectious Diseases, Tokyo, Japan) that caused a systemic infection in mice.Y. pestis no. 22 was intraperitoneally...

Prevalence of the speA2 and speA3 alleles in Streptococcus pyogenes isolated from TSLS patients in Japan

Masakado Matsumoto, Teiko Murai, Satoshi Ichiyama, Makoto Saito, more

FEMS Microbiology Letters > 1997 > 150 > 2 > 233-237

More than 100 cases have been identified as streptococcal toxic shock-like syndrome (TSLS) in Japan, since the first case was reported in 1993. Of 26 S. pyogenes isolates associated with TSLS, 69% were M-types 1 and 3. This study focused on speA alleles which were carried by all M-type 1 and 3 isolates and isolates of some other M-types, irrespective of sources. We sequenced the nucleotides of the...

In Vitro Activity of Twenty-Three Antimicrobials Against Yersinia pestis Strains

Sachiko Goto, Akiyoshi Tsuji, Teiko Murai, Minoru Nishida, more

Journal of Infection and Chemotherapy > 1995 > 1 > 2 > 133-134

The microdilution method was used to determine the MICs of twenty-three antimicrobials against the 22 strains of Yersinia pestis that have been stocked in the National Institute of Health, Japan. The three fluoroquinolones, ofloxacin, ciprofloxacin and sparfloxacin, were most active, with MIC _90S of 0.125μg/ml. The cephems showed considerable differences in activity: cefdinir and cefotaxime...
