A comparison of the population structures of methicillin-susceptible <i>Staphylococcus aureus</i> isolates from patients with infective endocarditis (IE) or bloodstream infection (BSI) without IE^a.

aIE and non-IE isolates were collected in 2008 and 2006, respectively. bMLST Clonal Complexes were inferred from microarray analysis. cP-values were calculated for each CC using a two-tailed Fisher's exact test. The P-value for the whole contingency table was 0.592.a 感染性心内膜炎（Infective Endocarditis, IE）与非感染性心内膜炎（non-IE）分离株分别于2008年和2006年采集。 b 多位点序列分型（Multilocus Sequence Typing, MLST）克隆群由微阵列分析结果推断得到。 c 针对每个克隆群（Clonal Complexes, CC）采用双侧费希尔精确检验计算P值。整张列联表的P值为0.592。
