As media we used: Standard-I-Nutrient Broth, Todd Hewitt Broth, Mueller-Hinton Broth, Isosensitest Broth and a chemically defined liquid medium. The magnesium content of these media was determined using flame photometry and was subsequently changed using magnesium sulfate to the magnesium concentrations as shown in table 1. In each of these media the TSST-1 positive S. aureus strains MN8 and T 40 were grown at 37 degrees C, 18 h, vigorously shaken. Then the colony forming units (cfu) were determined. Toxin assays were performed by immunodiffusion after concentrating the culture fluids 100-fold using ethanol precipitation. Concentrations of toxin per milliliter were determined by comparison with standard toxin preparations using hyperimmune-TSST-1 antisera as described. The cfu and the amount of TSST-1 produced are shown in table 1. No link could be demonstrated between TSST-1 production and magnesium concentration of the media used. Our results are in agreement with the ones published by Schlievert and disagree with the results from Mills.","PeriodicalId":23821,"journal":{"name":"Zentralblatt fur Bakteriologie, Mikrobiologie, und Hygiene.

A hose pump was used for continuous supply of sterile nutrient to a liquid bacterial culture containing both antibiotics in a preselected concentration and for removal of fluid from the system at an identical flow rate. To account for the different half-life periods of the antibiotics, a solution containing the antibiotic having a longer half-life in a corresponding concentration was continuously added by pumping. Samples were taken at fixed intervals to determine bacterial counts and check the expected concentrations of active substance did not contain antibiotics. This model has been developed to enable a determination of the dynamic relationship between the course of concentrations of antibiotics and their antibacterial activity. To permit a statement on the synergistic, indifferent or antagonistic activity of the combination, in analogy to the FIC indices in the checkerboard technique, the relative reduction of the bacterial count by the combination as compared to the individual components at time t was calculated. The model has been demonstrated by the example of the combined action of azlocillin and gentamicin against a strain of Klebsiella pneumoniae. In a simple way, the model permits any increase in the number of combination partners having different half-life periods. The mathematical development of the model is explained in detail.","PeriodicalId":23821,"journal":{"name":"Zentralblatt fur Bakteriologie, Mikrobiologie, und Hygiene.

Results of 4 laboratories in Austria].","authors":"H Mittermayer, M Rotter, F Riezinger, W Thiel, G Stanek","doi":"","DOIUrl":"","url":null,"abstract":"The susceptibility of 197 strains of the Bacteroides fragilis group (109 B. fragilis, 27 B. thetaiotamicron, 23 B. vulgatus, 1 B. distasonis, 11 B. ovatus and others) to penicillin G, cefoxitin, latamoxef, piperacillin, mezlocillin, clindamycin, metronidazole, tetracycline, doxycycline and chloramphenicol was tested by an agar dilution method. 4 microbiological laboratories in Austria participated in this investigation. In all laboratories the same method was used and a joint quality control carried out. The most active substances were metronidazole and clindamycin (MIC50 1.0 and 0.5 respectively; MIC90 4 mg/l for both). Tetracycline showed only little activity, whereas doxycycline inhibited a major portion of the strains at therapeutically relevant concentrations (MIC50 16 and 2 mg/l, MIC90 32 and 16 mg/l, respectively). The MIC90 of chloramphenicol was 8 mg/l. Piperacillin and mezlocillin were about equally active (MIC50 both 16, MIC90 32 and 64 mg/l, respectively). For penicillin G, the MIC values were also favourable, the MIC90 being 32 mg/l. The possible causes for the discrepancy between the good in vitro activity and the clinical ineffectiveness of penicillin G are discussed. The cumulative MIC values (50, 90%) for cefoxitin were 8 and 32 mg/l, respectively. The MIC's of latamoxef showed a wide distribution resulting in a low MIC50 (4 mg/l) and a high MIC90 (128 mg/l). This distribution was due to the differing susceptibility of the individual species within the Bacteroides fragilis group. For B. thetaiotaomicron the highest MIC values were determined. This species as a whole was less susceptible to the beta-lactam antibiotics tested. The non beta-lactam antibiotics showed no substantial species related differences. No relevant differences between the individual laboratories were observed.","PeriodicalId":23821,"journal":{"name":"Zentralblatt fur Bakteriologie, Mikrobiologie, und Hygiene.
