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)
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 in vitro activity of cefpodoxime against anaerobic respiratory tract and oropharyngeal pathogens 77 strains belonging to 18 gram-negative and 7 gram-positive species were studied by means of agar dilution tests. For comparison cefuroxime, amoxicillin, amoxicillin + clavulanic acid and clindamycin were also tested. Cefpodoxime was found to be(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)
Acute alcohol intake produces marked damage to gastric mucosa. Whether gastric mucosa develops tolerance to repeated alcohol administration is unknown. To test this, we compared the effects of acute and chronic alcohol administration in male rats. Thirty-one Sprague-Dawley rats maintained on Chow diet received the following: group A, water for 4 weeks;(More)
The in vitro activity of doxycycline against 147 strains of gram-positive and gram-negative anaerobes was determined by broth dilution, agar dilution and agar diffusion tests. The strains were isolated from clinical specimens in 1977. Saccharolytic Bacteroides strains (39 B. fragilis, 6 B. thetaiotaomicron, 4 B. vulgatus) showed broth dilution MICs of less(More)
