概括
在日本,肉中的第三代抗塞法洛斯波林沙门氏菌 (Salmonella Infantis) 已被敏感的沙门氏菌 (Salmonella Schwarzengrund) 取代. 这一转变凸显了减少肉群中的沙门氏菌流行率的重要性,以预防食物传播疾病.
科学领域:
- 食品安全与微生物学
- 对抗生素耐药性的监测和监测
- 兽医公共卫生 兽医公共卫生
背景情况:
- 沙门氏菌感染是导致食物传播疾病的主要原因,对第三代头素 (TGC) 的耐药性构成了全球健康的重大威胁.
- 在日本,未煮熟的肉是沙门氏菌肠炎的主要来源,因此需要持续监测家禽的抗菌素耐药性.
- 之前的研究表明,在日本肉群中存在抗TGC耐药的沙门氏菌.
研究的目的:
- 调查日本肉群和肉制品中第三代抗素 (TGC) 沙门氏菌的流行情况和趋势.
- 随着时间的推移,监测沙门氏菌血清型及其抗菌素耐药性模式的变化.
- 评估家禽加工过程中交叉污染的可能性.
主要方法:
- 在2017年至2022年期间进行了三次调查,涉及日本东部和西部的四个屠宰场.
- 收集和分析 brojiler 群体样本和母乳肉样本以隔离和识别沙门氏菌.
- 确定了孤立的沙门氏菌菌株的抗微生物敏感性概况,重点关注TGC耐药性.
主要成果:
- 在大量肉群中检测到沙门氏菌 (84.4%和90.6%在前两个调查中).
- 最初,确定了抗TGC的萨尔摩内拉婴儿菌,但随后的调查显示,转向了对TGC敏感的沙门氏菌.
- 在一个案例中,有人建议将肉与沙门氏菌交叉污染,这强调了加工卫生的重要性.
结论:
- 对TGC敏感的沙门氏菌Schwarzengrund在很大程度上取代了对TGC耐药的沙门氏菌Infantis在日本肉群中.
- 虽然可以发生交叉污染,但减少肉群体内的沙门氏菌流行率对于公共卫生至关重要.
- 持续监测对于跟踪食物传播病原体中不断演变的抗菌素耐药性趋势至关重要.

00:49Complementation Tests
4.9K
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

02:27Background and Environment Affect Phenotype
6.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
