| 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 |
| molecular epidemiology of beta-lactamase-producing enterococci. | plasmids from the first six reported beta-lactamase-producing (bla+) enterococci were compared for genetic relatedness. bla+ enterococcal plasmids from strains isolated in houston, tex.; philadelphia, pa.; connecticut; and pittsburgh, pa., had heterogeneous haeiii and mspi-clai restriction endonuclease digestion patterns. a staphylococcal beta-lactamase probe hybridized to all six bla+ enterococcal plasmids, but hybridization was detected on different haeiii and mspi-clai fragments of the six pl ... | 1990 | 2109577 |

| classification of bacteria from commercial egg washers and washed and unwashed eggs. | a total of 432 bacterial isolates from washed and unwashed eggs, egg-washer surfaces, and washwaters from five egg-grading plants in maryland and southeastern pennsylvania were classified. counts on equipment surfaces showed considerable variation from plant to plant, reflecting care used in cleaning. unwashed eggs had a higher percentage of gram-positive cocci (71%), and isolates included streptococcus faecalis, aerococcus, and escherichia coli, which were not isolated from equipment surfaces a ... | 1980 | 6893532 |
| vancomycin-resistant staphylococcus aureus--pennsylvania, 2002. | staphylococcus aureus is one of the most common causes of hospital- and community-acquired infections. since the recognition of vancomycin-resistant enterococci in 1988, the emergence of vancomycin-resistant s. aureus (vrsa) (minimum inhibitory concentration [mic] > or = 32 microg/ml) has been anticipated. the transfer of the genetic element containing the vana vancomycin resistance gene from enterococcus faecalis to s. aureus was demonstrated in the laboratory in 1992; the first clinical infect ... | 2002 | 12418544 |
| slaughterhouse survey of pyelonephritis in dairy cows. | twenty-one rejected kidneys from 2426 slaughtered dairy cows (0.87 per cent) had gross signs of pyelonephritis that were confirmed by histopathology. in all the kidneys the findings were consistent with a chronic rather than an acute infection. one species of bacteria was cultured from 12 of the kidneys and two species of bacteria were cultured from six. the most commonly isolated bacteria were escherichia coli, from eight kidneys, arcanobacterium pyogenes, from seven kidneys and corynebacterium ... | 2005 | 16299366 |
