| evidence for clonal spread of a single strain of beta-lactamase-producing enterococcus (streptococcus) faecalis to six hospitals in five states. | beta-lactamase-producing (bla+) enterococci have been reported in three state and two countries. pulsed-field gel electrophoresis was used to compare 14 bla+ enterococcus (streptococcus) faecalis isolated from hospitalized patients in seven states and three continents. the restriction endonuclease digestion patterns of isolates from connecticut, massachusetts, lebanon, and argentina were all markedly different, indicating that these were different strains. however, isolates from delaware, texas, ... | 1991 | 1901330 |
| distribution of indicator bacteria and vibrio parahaemolyticus in sewage-polluted intertidal sediments. | the impact of a sewage point source on the bacterial densities in an intertidal mud flat in boston harbor, mass., was investigated. the area, savin hill cove, acts as a receiving basin for a combined storm and sewage outlet (cso). preliminary examination of sediments and overlying water at high tide demonstrated that fecal coliforms were present in sediments at abundances 2 to 4 orders of magnitude higher than in the overlying water column. the following bacterial counts were determined from sed ... | 1987 | 3116932 |
| hiv-infected children in the pediatric emergency department. | forty-three nonhemophiliac, confirmed hiv-positive children followed by the children's hospital aids program made 184 visits to the children's emergency department (ed) during 1988 and 1989. the mean age was 30 +/- 28 months with a median of 25 months, a mode of 10 months, and a range from two days to 19 years. cd4 counts from within six months of the visit were available in 87% and were low enough to require pneumocystis carinii pneumonia prophylaxis under current guidelines in 52%. chief compl ... | 1993 | 8247930 |
| comparison of the duration of antimicrobial activity of 2 different antimicrobial central venous catheters. | we compared the duration of antimicrobial effectiveness of 2 different antimicrobial catheters. the baseline activity of minocycline-rifampin catheters was greater than that of silver-platinum-carbon catheters against staphylococcus aureus, staphylococcus epidermidis, and enterococcus faecalis. the antimicrobial activity of the minocycline-rifampin catheters against these pathogens persisted for up to 12 days, while that of the silver-platinum-carbon catheters was depleted by day 10 (p < .05). | 2010 | 20100086 |
| emergence of gentamicin-resistant bacteremia in hemodialysis patients receiving gentamicin lock catheter prophylaxis. | antibiotic locks in catheter-dependent chronic hemodialysis patients reduce the rate of catheter-related blood stream infections (cris), but there are no data regarding the long-term consequences of this practice. | 2010 | 20595689 |
| american crows as carriers of vancomycin-resistant enterococci with vana gene. | we studied the vana-carrying vancomycin-resistant enterococci (vre) isolated from american crows in the united states during the winter 2011/2012. faecal samples from crows were cultured selectively for vre and characterized. pulsed-field gel electrophoresis (pfge) and multilocus sequence typing (mlst) were used to examine epidemiological relationships of vana-containing vre. isolates were tested in vitro for their ability to horizontally transfer the vancomycin resistance trait. vre with the va ... | 2014 | 23919480 |
