概括
多种耐药性食品传递病原体,如大肠杆菌和沙门氏菌种在原始食品中普遍存在,有助于抗生素耐药性的传播. 分子分析证实了耐药性基因,突出了对抗性基因的需求.
科学领域:
- 食品安全和抗菌素耐药性研究.
- 微生物学和分子生物学.
- 公共卫生和兽医科学.
背景情况:
- 食物传播的病原体,包括大肠杆菌,金黄色葡萄球菌和沙门氏菌,是通过食品供应链传播抗生素耐药性的重要贡献者.
- 了解这些耐药病原体在原始食品中的流行和特征对于控制它们的传播至关重要.
研究的目的:
- 为了确定原始食品中多种耐药性食品传播病原体的频率.
- 确定抗生素耐药性病原体传播的潜在来源.
- 描述抗生素敏感性概况和检测孤立病原体中的耐药性基因.
主要方法:
- 从各种原始食品中收集和隔离食源性病原体 (大肠杆菌,沙门氏菌,金黄色杆菌).
- 使用临床实验室标准研究所指导方针确定抗生素敏感性概况.
- 使用聚合酶链反应 (PCR) 检测特定的耐药基因 (blaTEM-1,mecA).
主要成果:
- 总共有268个食品隔离物被回收,病原体回收与食品来源之间存在显著的相关性.
- 观察到同一个食品样本内同时存在多种食源性病原体.
- 几乎所有分离物都对至少一种抗生素表现出耐药性,分别在大肠杆菌,沙门氏菌和黄金氏菌中检测到blaTEM-1和mecA基因.
结论:
- 生食物品含有多种耐药性食品传播病原体,构成抗生素耐药性传播的风险.
- 由于存在特定的抗药性基因,因此需要采用"一个健康"的方法来监测和跟踪人类,动物和环境卫生部门的抗生素耐药性.
- 跨部门的合作对于减轻来自食品来源的抗菌素耐药性的全球威胁至关重要.

Development of Antibiotic Resistance
259
Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...

Biological Methods for Microbial Control
219
Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Infection
8.8K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Defense Against Bacterial Pathogens
1.6K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
