自1968～1979年间,美国全国有32个州向疾病控制中心(CDC)报告了从脑脊液(CSF)分离到的383株沙门氏菌(S)。各年份报告菌株数量最少的为23株(1972及1975年),最多49株(1979年),平均每年为28.5株。除1949年外,其余年份报告的菌株数都未超过40株。8月份到1月份所报告的菌株数比例最高(66.2%),有非常显著的差异(P<0.001)。检出菌株的男性较女性为多(1.17:1),但无显著性差异。同时
From 1968 to 1979, 383 Salmonella isolates from cerebrospinal fluid (CSF) were reported to the Centers for Disease Control and Prevention (CDC) in 32 states throughout the United States. The least number of isolates was reported in each year (23 strains in 1972 and 1975) and 49 strains (in 1979), with an average of 28.5 strains per year. In addition to 1949, the rest of the reported strains did not exceed 40 strains. The highest number of isolates was reported from August to January (66.2%), with a very significant difference (P <0.001). Strain detected more men than women (1.17: 1), but no significant difference. Simultaneously
