[Antifungal susceptibility among the isolates of yeast from the University Hospital of the Ryukyus].

During the period from 1999 to 2003, A total of 2,255 isolates of yeast from the patients of the University Hospital of the Ryukyus were determined for their antifungal susceptibilities by the ASTY (Kyokuto Pharmaceutical Industrial Co., Ltd., Tokyo) colorimetric microdilution testing.

[Evaluation of a fully automated microbiology system, RAISUS to determine antimicrobial susceptibility for the isolates of Haemophilus influenzae].

A fully automated microbiology system, RAISUS (Nissui Pharmaceuticals Co., Ltd., Tokyo) was evaluated to determine antimicrobial susceptibility of the isolates of Haemophilus influenzae.

[Detection of vancomycin-resistant enterococci by a fully automated microbiology system, RAISUS].

A fully automated microbiology system, RAISUS recently developed (Nissui Pharmaceuticals Co., Ltd., Tokyo) was evaluated for identification of enterococci and for detection of vancomycin-resistant enterococci (VRE).

[Laboratory-based evaluation of a fully automated microbiology system, RAISUS for species-identification and antimicrobial susceptibility tests].

A fully automated microbiology system, RAISUS newly developed (Nissui Pharmaceuticals Co., Ltd., Tokyo) was evaluated for gram-positive and gram-negative clinical isolates.

[Antimicrobial susceptibility and prevalence of beta-lactamase producing clinical isolates in southern Kyushu. The results of collaborative study from 1999 to 2000].

The positivity of beta-lactamase and antimicrobial susceptibility were determined in a total of 1,358 clinical isolates at 15 hospitals and clinics in four prefectures in southern Kyushu (Okinawa, Miyazaki, Kagoshima and Kumamoto) during the period from December 1999 to February 2000. The isolates collected comprised of 176 strains of S. aureus, 203 of H.

[Multicenter evaluation of a newly developed microdilution test, brothMIC NTM to determine minimum inhibitory concentrations of antimicrobial agents for nontuberculous mycobacteria].

We developed a new broth microdilution susceptibility test for nontuberculous mycobacteria to determine minimum inhibitory concentrations(MICs). The test method utilized air-dried microplates containing serially diluted antimicrobial agents and the modified Middlebrook 7H9 broth. The nine agents tested were rifampicin, isoniazid, ethambutol, streptomycin, kanamycin, levofloxacin, clarithromycin, ethionamide and amikacin.
