JOURNAL FREE ACCESSThe present studies concern with clinical backgrounds of the patients from whom Ac. calcoaceticus was isolated at the Juntendo University Hospital from Oct. 1976 until May 1977, and in-vitro observations on the susceptibility to antibiotics and chemotherapeutic agents of the organisms isolated from various clinical specimens from Sept.1976 to May 1977.
One hundred and eight strains of Ac. calcoaceticus were isolated from various clinical specimens of 78 patients. Approximately 70% of them was isolated from respiratory tract, and 6-8% from urinary tract, wound or bile. Ninety six of 108 strains were isolated in combination with other organisms.
In retrospective view of 35 patients, all of them had one or more underlying diseases or predisposing factors, e.g., chronic disease, malignancy, infection due to other organism, surgery. Antibiotics had been administrated to 26 patients before onset of their infection with Ac. calcoaceticus.
According to in-vitro susceptibility testing, the most active antimicrobial agents were minocycline and doxycycline. Gentamicin, tetracycline, kanamycin, amikacin, dibekacin, colistin, erythromycin, nalidixic acid were active in this order. Most strains were resistant to ampicillin, sulbenicillin, cephaloridine, cefazolin, chloramphenicol, lincomycin, clindamycin, pipemidic acid and piperamic acid.View full abstractDownload PDF (1290K) -

JOURNAL FREE ACCESSThree hundreds and fifty-one strains of enterococci were isolated from 2,337 clinical materials including urine, blood, pus and others during 6 months of spring and summer in 1977. Urine was the most frequent source of the organism among them.
As for species, S. liquefaciens was isolated most frequently (45.5%), being followed by S.zymogenes (26.5%) and S. faecalis (21.5%) in order.
The susceptibility of the isolates was tested with 10 antibiotics. In general, the majority of the strains was resistant to several antibiotics, but almost all the strains were susceptible to ampicillin and benzylpenicillin. The susceptibility of S. liquefaciens, S. zymogenes and S. faecalis to 10 antibiotics was similar with each other in pattern, while that of S. faecium and S. durans was considerably lower.View full abstractDownload PDF (802K) -

JOURNAL FREE ACCESSThe present studies concern with clinical backgrounds of the patients from whom Ach. xylosoxidans was isolated from the clinical specimens at the Juntendo University Hospital from August 1976 until May 1977, and in vitro studies on the susceptibility of the organisms to antibiotics and chemotherapeutic agents.
Forty strains of Ach. xylosoxidans were isolated from 27 patients during this period; there were 19 strains from urine, 12 from respiratory tract, 8 from ear discharge and one from wound. Thirty six strains were recovered in combination with other organisms.
In three cases with chronic otitis media, Ach. xylosoxidans was apparently playing a causative role in disease. The cases, in which Ach. xylosoxidans was isolated from urine or sputum, had had some kinds of antibiotics, but the clinical details of the cases suggested that this organism was not playing a pathogenic role.
From the results of antibiotic sensitivity test, most of the strains were resistant to cefazolin, cephaloridine, kanamycin, gentamicin, dibekacin, amikacin, erythromycin, lincomycin, clindamycin, chloramphenicol, piperamic acid and pipemidic acid. Almost all were sensitive to minocycline and doxycycline and most were sensitive to colistin and nalidixic acid. About one third of the strains were sensitive to ampicillin and sulbenicillin.View full abstractDownload PDF (972K) -
