概括
韩国在分类和包装 (GP) 工厂强制洗蛋. 这项研究发现,在18.3%的蛋和20.0%的蛋含量中发现了非伤寒型沙门氏菌,其中S. Infantis是最常见的和多药耐药的.
科学领域:
- 食品安全 食品安全
- 微生物学 微生物学
- 兽医公共卫生 兽医公共卫生
背景情况:
- 韩国将在2020年对拥有超过1万只母的养殖场强制在分类和包装 (GP) 工厂洗蛋.
- 了解洗后的沙门氏菌患病率对于公共卫生和食品安全至关重要.
研究的目的:
- 在韩国GP工厂洗后的蛋中调查非伤寒型沙门氏菌的流行率和特征.
- 为了识别特定的沙门氏菌血清病毒及其毒性基因和抗菌素耐药性概况.
主要方法:
- 从60个GP植物收集了16800个蛋,这些蛋来自商业层农场的60个GP植物.
- 测试了840个聚合的蛋和蛋含量样本,以检测沙门氏菌spp. 使用微生物学方法.
- 标志着检测到的沙门氏菌分离物对血清菌,毒性基因和抗菌耐药性的特征.
主要成果:
- 沙门氏菌 spp. 沙门氏菌 检测到18.3%的蛋和20.0%的卵子含量从测试的GP植物.
- 在超过80周的母的蛋中,患病率最高 (33.3%的蛋,40.0%的蛋含量).
- 沙门氏菌Infantis是最常见的血清在两个蛋和内容,表现出多药性耐药性 (MDR).
- 在某些血清病毒中确定了特定的毒性基因 (spvB,sefC),MDR在隔离物之间有所不同.
结论:
- 来自GP植物的洗蛋仍然可以携带非伤寒型沙门氏菌,特别是来自老群的蛋.
- 沙门氏菌因其流行率和多药耐药性而构成重大风险.
- 需要加强卵子GP植物的监测和管理策略,以减少污染.

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...
