The mean minimum generation time in shake culture in urine of 6 urinary isolates of Escherichia coli (21.7 +/- 0.6 min) was significantly shorter (P = 0.0003) than that of 14 isolates of less common urinary pathogens (46.0 +/- 18.6 min). Mixed populations of approximately equal numbers of E. coli cells paired with other urinary, fecal, and urethral(More)
OBJECTIVE This study examined the relative precision of four methods of acupoint location: two traditional methods (directional and proportional) and two contemporary methods (elastic and ruler). DESIGN Seventy-two (72) subjects attempted to locate a fictitious acupoint (FP) with repeated attempts and the resulting coordinates were recorded. LOCATION(More)
Sixteen isolates of Escherichia coli were obtained from women with significant acute urinary tract infections who were subsequently treated with amoxicillin. The activities of amoxicillin and ampicillin against these organisms were compared in urine in a continuous culture apparatus which partly simulated the milieu of the human urinary bladder. After(More)
Disk susceptibility tests for mecillinam were carried out on 167 hospital isolates of Enterobacteriaceae from Vancouver. Inhibition zone sizes with eight experimental variations were compared by three-way analysis of variance. The Association of Clinical Pathologists' method gave significantly (p = 0.0002) larger zones than the Kirby Bauer method (24.9 +/-(More)
