肠炎沙门氏菌通常因食用受污染的食物而感染，是全球范围内疾病的一个重要病因。需要采取干预措施来控制沙门氏菌；通过血清分型对沙门氏菌进行亚型分类对于确定此类干预措施的目标是有用的。因此，我们分析了2001年至2007年期间从参与世界卫生组织全球食源性感染网络且在全球食源性感染网络外部质量保证体系中证明具有血清分型能力的37个国家的实验室中从人类分离出的15种最常鉴定出的沙门氏菌血清型的全球分布情况。在整个研究期间的所有地区，除大洋洲和北美洲地区外，肠炎沙门氏菌血清型肠炎亚种和鼠伤寒亚种分别是最常见和第二常见的血清型。在北美洲和大洋洲（澳大利亚和新西兰）地区，鼠伤寒沙门氏菌血清型是报告的最常见血清型，肠炎沙门氏菌血清型是第二常见血清型。在研究期间，从人类报告的沙门氏菌分离株中肠炎沙门氏菌血清型肠炎亚种所占比例为43.5%（范围：2007年的40.6%到2003年的44.9%），鼠伤寒沙门氏菌血清型为17.1%（范围：2007年的15%到2001年的18.9%）。新港沙门氏菌血清型（主要在拉丁美洲、北美洲和欧洲国家出现）、婴儿沙门氏菌血清型（在所有地区占主导）、维尔肖沙门氏菌血清型（主要在亚洲、欧洲和大洋洲国家出现）、哈达尔沙门氏菌血清型（在欧洲国家常见）和阿贡纳沙门氏菌血清型（在拉丁美洲、北美洲和欧洲国家较多）也经常被分离出来，总体比例分别为3.5%、1.8%、1.5%、1.5%和0.8%。不同地区之间最常分离出的血清型存在很大差异，但同一地区内的国家之间差异较小。研究结果还凸显了沙门氏菌全球流行病学的复杂性，以及改进对那些具有最高流行病学重要性的血清型的监测数据的必要性和重要性。
Salmonella enterica is commonly acquired from contaminated food and is an important cause of illness worldwide. Interventions are needed to control Salmonella; subtyping Salmonella by serotyping is useful for targeting such interventions. We, therefore, analyzed the global distribution of the 15 most frequently identified serovars of Salmonella isolated from humans from 2001 to 2007 in laboratories from 37 countries that participated in World Health Organization Global Foodborne Infections Network and demonstrated serotyping proficiency in the Global Foodborne Infections Network External Quality Assurance System. In all regions throughout the study period, with the exception of the Oceania and North American regions, Salmonella serovars Enteritidis and Typhimurium ranked as the most common and second most common serovar, respectively. In the North American and Oceania (Australia and New Zealand) regions, Salmonella serovar Typhimurium was the most common serovar reported, and Salmonella serovar Enteritidis was the second most common serovar. During the study period, the proportion of Salmonella isolates reported from humans that were Salmonella serovar Enteritidis was 43.5% (range: 40.6% [2007] to 44.9% [2003]), and Salmonella serovar Typhimurium was 17.1% (range: 15% [2007] to 18.9% [2001]). Salmonella serovars Newport (mainly observed in Latin and North American and European countries), Infantis (dominating in all regions), Virchow (mainly observed in Asian, European, and Oceanic countries), Hadar (profound in European countries), and Agona (intense in Latin and North American and European countries) were also frequently isolated with an overall proportion of 3.5%, 1.8%, 1.5%, 1.5%, and 0.8%, respectively. There were large differences in the most commonly isolated serovars between regions, but lesser differences between countries within the same region. The results also highlight the complexity of the global epidemiology of Salmonella and the need and importance for improving monitoring data of those serovars of highest epidemiologic importance.
