The susceptibility of more than 40 strains of Gram-negative and Gram-positive anaerobes to tiamulin (Sandoz 81.723 hfu), a new pleuromulin (pleuromutilin) derivative, was determined by broth dilution and agar dilution tests. The influences of density of the inoculum upon MICs was studied by a specially designed pour plate-technique. Bacteroides fragilis, B.(More)
To assess the specificity and sensitivity of Fluorocult media for the identification of Escherichia coli, the beta-glucuronidase activities of 1,258 bacterial strains, as well as 20 strains of Candida spp., were investigated. Fluorescence of colonies combined with positive indole reaction resulted in specificities of 99.6 to 99.8%. Sensitivities were 59.1%(More)
Experimental studies on rabbit eyes were performed to examine the penetration capacity of cefsulodin into the anterior chamber and the vitreous body. One group of animals was injected with 50 mg/kg body weight intravenously, the other group received 20 mg subconjunctivally. Samples of the anterior chamber and the vitreous body were taken from the(More)
AThe presence of diaminopimelic acid (m-DAP) in strains of Bacteroides melaninogenicus, B. bivius and other species as well as in unidentified strains of Bacteroides was investigated by thin-layer chromatography. Strains of B. bivius and B. disiens all contained m-DAP as did the subspecies intermedius and melaninogenicus of B. melaninogenicus. Strains of B.(More)
The Children's Clinic in Giessen, Germany recently reported several severe infections with Klebsiella oxytoca resulting in deaths of two neonates. The putative source of the infections was a contaminated infusion solution. The resistance to disinfectant of the K. oxytoca isolates was investigated in three independent laboratories and was indeed found to be(More)
The occurrence of bacteria in 12 endodontically induced periodontal lesions associated with sinus tracts was examined. The microbial flora encountered in the sinus tract was compared with that of the root canal of the involved teeth which had not experienced any prior endodontic therapy. All microbiological samples taken from the sinus tract and from the(More)
