Metronidazole, an antibiotic with specific activity against anaerobic bacteria, was of clinical and biochemical benefit in two patients with methylmalonic aciduria. The virtual elimination of propionic acid from the stool suggested that propionic acid derived from faecal bacterial metabolism contributes substantially to methylmalonate production. These(More)
In addition to the two major toxins of Clostridium difficile--toxins A and B, which represent the major virulence factors--a number of other putative virulence factors have been described. These factors include fimbriae and the ability to associate with gut cells/mucus, the production of a capsule, the secretion of a range of hydrolytic enzymes, the(More)
The microbial flora and some of its metabolites and enzymes in the stomach were compared in patients with achlorhydria, pernicious anaemia, and primary hypogammaglobulinaemia and in patients with dyspepsia with normal gastric acidity. Detailed analysis of the flora of the gastric juice and of the mucosa from the antrum, body, and fundus in six patients with(More)
Highly purified toxin A of Clostridium difficile was obtained by bovine thyroglobulin affinity chromatography followed by two sequential anion-exchange chromatography steps on Q Sepharose FF and Mono Q. After Q Sepharose FF chromatography of a thyroglobulin affinity-purified toxin A preparation, two major peaks of cytotoxicity representing toxins A and B(More)
Swabs were able to absorb enough extractable volatile fatty acids from broth cultures of anaerobic organisms for detection and analysis by gas-liquid chromatography (GLC). Similarly, volatile fatty acids were often detected in swabs dipped into liquid pus. Fifty-three liquid pus specimens were then investigated fully to determine if GLC analysis of swab(More)
Virulent toxigenic and avirulent non-toxigenic strains of Clostridium difficile gave a positive result in the latex agglutination test (LAT) for C difficile toxin A (D-1). Similar concentrations of latex agglutinating antigen were produced by these strains in vivo. Positive reactions were also given by C sporogenes, proteolytic C botulinum Types A, B, and(More)
Concentrations of air-borne bacteria and particles have been measured in turbulently ventilated operating theatres in full flow, half flow and zero flow conditions. Increased air-borne challenge produced by human activity and by mechanical cleaning procedures is demonstrated: die-away of this contamination is shown to be related to the ventilation rate.(More)
OBJECTIVE To compare angiotensin-converting enzyme (ACE) inhibitor use in patients with type 2 diabetes at 1 year and 3 years after guidelines were published. STUDY DESIGN Retrospective database review. PATIENTS AND METHODS The drug utilization review database of a state managed care plan was accessed to retrieve 2 random samples of 500 patients each.(More)
UNLABELLED This activity is designed for pharmacists, physicians, physician assistants, nurses, and other healthcare team members; payers for health services; and healthcare executives. GOAL To provide basic information on the methods used and computer software available for evaluating invariant factorial structures, such as those found in health status(More)
Thirty-two strains of anaerobic curved rods isolated from vaginal secretions and one isolated from seminal fluid were examined. Growth of all strains on solid media was superior to growth in liquid media, and at 37 degrees C they grew both anaerobically and in O2 5% in N2; they also grew anaerobically at 33 degrees C but not at 42 degrees C. No growth(More)
