概括

滋果毒素产生大肠杆菌 (STEC) 可以导致血清性尿素综合征 (HUS). 5岁以下的儿童具有特定的STEC毒素配置,特别是Shiga毒素2 (stx2),面临HUS风险最高.

科学领域:

儿童传染病儿童传染病
微生物学微生物学
腎臟病學 (nephrology) 是一種醫學專業.

背景情况:

血溶性尿性综合征 (HUS) 是滋果毒素产生大肠杆菌 (STEC) 感染的严重并发症.
准确识别STEC毒素概况和预测HUS的临床因素对于指导管理和查协议至关重要.

研究的目的:

确定特定的Siga毒素产生大肠杆菌 (STEC) 毒素配置文件和与发展血清性尿素综合征 (HUS) 的最高风险相关的临床变量.
为制定基于证据的儿童HUS查指南提供信息.

主要方法:

一项为期5年的回顾性研究分析了1071名18岁以下的STEC阳性便儿童的数据.
收集了人口统计数据,临床症状和实验室结果,后勤回归确定了HUS进展的预测因素.

主要成果:

55名儿童患上了HUS,在5岁以下的儿童中观察到更高的风险,并且感染了产生Shiga毒素2 (stx2) 的大肠杆菌O157或非O157菌株.
儿童中没有发生HUS病例,仅有O157,O157和stx1,或非O157stx1和stx2. 吐,脱水和异常的血液细胞计数/化学反应是临床预测因素.

结论:

HUS风险受到大肠杆菌血清型和Shiga毒素 (stx) 类型的显著影响,其中stx2是主要的驱动因素.
查指南应考虑大肠杆菌血清型和stx结果. 家庭需要关于HUS症状和脱水预防的咨询;系列实验室监测是针对高风险儿童的.

Lysogenic Cycle of Bacteriophages

Lysogenic Cycle of Bacteriophages

In contrast to the lytic cycle, phages infecting bacteria via the lysogenic cycle do not immediately kill their host cell. Instead, they combine their genome with the host genome, allowing the bacteria to replicate the phage DNA along with the bacterial genome. The incorporated copy of the phage genome is called the prophage. Some prophages can re-activate and enter the lytic cycle. This often occurs in response to a perturbation, such as DNA damage, but can also transpire in the absence of...
