PURPOSE To describe two outbreaks of Angiostrongylus cantonensis infection that occurred in Kaohsiung, Taiwan, during 1998 and 1999, and to characterize the source of the outbreaks and the clinical manifestations of the disease. SUBJECTS AND METHODS We performed a retrospective cohort study among Thai laborers with eosinophilic meningitis who ate raw(More)
OBJECTIVE Indwelling urinary catheters are the most common source of infections in intensive care units (ICUs). The aim of this study was to evaluate the efficacy of nurse-generated daily reminders to physicians to remove unnecessary urinary catheters 5 days after insertion. DESIGN A time-sequence nonrandomized intervention study. SETTING Adult ICUs(More)
Staphylococcus saprophyticus is a leading cause of cystitis in young women. S. saprophyticus shares many clinical features of urinary tract infection caused by Escherichia coli, but differs in pathogenesis, seasonal variation, and geographic distribution. This review summarizes what is known and what still needs to be learned about this microorganism.
OBJECTIVES Fluoroquinolones are being used more frequently for the treatment of multidrug-resistant (MDR) strains of Mycobacterium tuberculosis complex (MTB). This study was designed to determine the frequency of the emergence of fluoroquinolone-resistant strains in Taiwan and to assess whether this might be due to use of fluoroquinolones for treatment of(More)
Glycine betaine is believed to be the most active naturally occurring osmoprotectant molecule for Escherichia coli and other bacteria. It is a dipolar ion possessing a quaternary ammonimum group and a carboxylic acid group. To examine the molecular requirements for osmoprotective activity, dimethylthetin was compared with glycine betaine. Dimethylthetin is(More)
The purchase of antimicrobial agents in drugstores in a district in Manila. The Philippines was examined in order to determine how these agents might be used. Most antimicrobial agents are imported as bulk products and repackaged by a large number of small firms into 1491 different preparations including 206 marketed as combinations with other drugs.(More)
The objective of the study was to determine the patterns of use of antimicrobial drugs in the general population of the large, industrial city of Nagpur, India. Interviews of pharmacists and clients were carried out in a stratified, random sample of 34 pharmacies to determine beliefs and practices in prescribing and self-prescribing of antibiotics by(More)
Growth of Escherichia coli was inhibited in a defined minimal medium by high concentrations of electrolytes and sugars in direct relation to their osmotic strength. Choline, betaine, proline, and human urine increased resistance to these substances. In contrast, the toxic effect of urea was not altered directly by betaine or urine, but was reduced in the(More)
