''Streptococcus pseudopneumoniae'' is a gram-positive coccus that may cause pneumonia in humans. It was first described in 2004.〔 The organism is often mistaken for ''S. pneumoniae''〔 and its clinical importance is as yet uncertain. It seems likely that most cases of ''S. pseudopneumoniae'' pneumonia are misdiagnosed as ''S. pneumoniae''.〔 The bacterium has a number of features that allows it to be distinguished from ''S. pneumoniae'':〔 * There is no pneumococcal capsule (and is therefore not typable).〔 * It is not soluble in bile.〔 * It is sensitive to optochin when incubated in ambient air, but appears resistant or to have indeterminate susceptibility when incubated in 5% carbon dioxide.〔 * Commercial DNA probe hybridization tests (e.g., AccuProbe ''Streptococcus pneumoniae'' culture identification test; Gen-Probe, San Diego, CA) are falsely positive.〔 Penicillin is the treatment of choice.〔 Most reported isolates are resistant to erythromycin and to tetracycline. == References == 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Streptococcus pseudopneumoniae」の詳細全文を読む スポンサード リンク
