Enterococcus durans
open-in-new
<p><i>Enterococcus durans</i> is a species of <i><a href="/facts/Enterococcus/fHlRoS0V">Enterococcus</a></i>. It is a <a href="/facts/Gram-positive_bacteria/H6WYQ17e">gram-positive</a>, <a href="/facts/Catalase/CcJ9r5KG">catalase</a>- and <a href="/facts/Oxidase_test/UB7VGeWl">oxidase</a>-negative, <a href="/facts/Coccus/51QVlEDC">coccus</a> bacterium. The organism is also a <a href="/facts/Facultative_anaerobic_organism/YS9tdh8N">facultative anaerobic organism</a>. Prior to 1984, it was known as <i>Streptococcus durans</i>. </p><p>Certain strains have also been identified as producers of <a href="/facts/Anti-inflammatory/W27poSUd">anti-inflammatory</a> agents, which are being studied in medical research. <i>E. durans</i> is less commonly isolated in clinical infections than <i><a href="/facts/Enterococcus_faecalis/66cjKlxr">E. faecalis</a></i> and <i><a href="/facts/Enterococcus_faecium/Ek2mFsQP">E. faecium</a></i>, but it has been increasingly recognized in hospital settings, particularly in patients with urinary catheters and prolonged antibiotic exposure. </p> <h3>Metabolism</h3> <p>In terms of metabolism, <i>E. durans</i> primarily shares its substrate utilization profile with <i>E. faecium</i>. It can metabolize <a href="/facts/Arabinose/7WDWSEzV">L-arabinose</a> (weakly), <a href="/facts/Melibiose/WdLyk5N5">melibiose</a> and <a href="/facts/Lactose/lBa5ozYk">lactose</a> which aids in its biochemical distinction from <i>E. faecalis</i>. <i>E. durans</i> is often misidentified in clinical diagnostics due to phenotypic overlap with <i>E. faecium</i>, especially when relying on <a href="/facts/Matrix-assisted_laser_desorption%2fionization/nBBXfb2Q">MALDI-TOF</a> mass spectrometry. <a href="/facts/Whole_genome_sequencing/WNuHaU2K">Whole-genome sequencing</a> are increasingly recommended for accurate identification and characterization. </p>
