| enterococcus casseliflavus septicaemia associated with hepatobiliary infection in a 75-year-old man. | enterococcus casseliflavus is a rare non-faecium, non-faecalis, vancomycin-resistant enterococcus (vre) that is responsible for up to 2% of all enterococcal infections. septicaemia with this bacterium is usually seen in older patients with multiple comorbidities who have had several previous hospitalisations. septicaemia with e. casseliflavus portends a poorer prognosis, and treatment usually involves administration of antienterococcal beta-lactams or anti-vre medications such as linezolid or da ... | 2017 | 28500123 |
| environmental growth of enterococci and escherichia coli in feedlot catch basins and a constructed wetland in the absence of fecal input. | population structures of fecal indicator bacteria (fib) isolated from catch basins, a constructed wetland, and feces from a beef cattle feedlot were compared over a two-year period. enterococcus hirae accounted for 92% of the fecal isolates, whereas secondary environments were characterized by greater relative abundance of environmentally adapted species including enterococcus casseliflavus. while enterococci densities in the catch basins and wetland were similar under wet and drought conditions ... | 2017 | 28430425 |
| draft genome sequence of enterococcus casseliflavus pavet15 obtained from the oviduct infection of the cattle tick (rhipicephalus microplus) in jiutepec, morelos, mexico. | enterococcus spp. are gram-positive lactic acid-producing bacteria found in the intestinal tracts of animals, like mammals, birds, and arthropods. enterococcus spp. may cause oportunistic infections in vertebrate and invertebrate hosts. we report here the draft genome sequence of enterococcus casseliflavus pavet15 containing 3,722,480 bp, with 80 contigs, an n50 of 179,476 bp, and 41.93% g+c content. | 2017 | 28428300 |
| bloodstream infections caused by enterococcus spp: a 10-year retrospective analysis at a tertiary hospital in china. | in order to discover the risk factors for 30-day mortality in bloodstream infections (bsi) caused by enterococcus spp. strains, we explored the clinical and therapeutic profile of patients with enterococcus spp. bsi and the characteristics of this condition. a total of 64 patients with bsi caused by enterococcus spp. who were treated in our hospital between 2006 and 2015 were included in the study. the clinical features of patients, microbiology, and 30-day mortality were collected from the elec ... | 2017 | 28397040 |
