概括
2023年澳大利亚肠球菌监测结果计划 (AESOP) 发现肠球菌细菌病的抗菌素耐药性高,特别是肠球菌中的万科米辛耐药性. 这凸显了澳大利亚对这些感染的治疗选择有限.
科学领域:
- 医学微生物学 医学微生物学
- 传染性疾病 传染性疾病
- 对抗生素耐药性的监测和监测
背景情况:
- 肠球菌细菌病在全球范围内构成了重大临床挑战.
- 肠球菌 (Enterococcus faecium) 和肠球菌 (Enterococcus faecalis) 是医院感染的常见致病原体.
- 肠球菌中的抗菌素耐药性需要持续监测.
研究的目的:
- 为了确定在澳大利亚的肠球菌细菌病分离体中抗菌素耐药性的流行率.
- 为了研究Enterococcus faecium分离物的分子流行病学.
- 评估阻力模式的趋势,并确定关键序列类型.
主要方法:
- 从56个澳大利亚机构 (2023) 分析了1,599个独特的肠球菌性细菌病发作.
- 对常见药物的抗微生物敏感性测试,包括安皮西林,万科米辛和线索利德.
- 对Enterococcus faecium分离物的分子表征,包括多位置序列类型 (MLST) 和抗性基因 (vanA,vanB, optrA) 的检测.
主要成果:
- 其中Enterococcus faecalis (51.8%) 和Enterococcus faecium (41.1%) 是主要的物种.
- 在E. faecium.中观察到高水平的安皮西林 (94.2%) 和万科米辛 (50.8%) 耐药性.
- 确定了两种携带 optrA 基因的对线胺耐药 E. faecalis 隔离物.
- 大多数抗万科胺素的E. faecium含有vanB (72.1%) 或vanA (27.3%) 基因.
- E. faecium分离物主要属于克隆复合体17,有七种主要的序列类型分布在澳大利亚.
- 58.3%的主要ST的分离物携带vanA或vanB基因.
结论:
- 澳大利亚的肠球菌性细菌病常常是由多药耐药的Enterococcus faecium引起的.
- 对于E. faecium中高患病率的万科米辛耐药性仍然令人担忧,在许多欧洲国家超过了率.
- 具有 optrA 的线索利德耐药 E. faecalis 的存在需要密切监测.
- 对于由这些耐药性肠球菌菌株引起的感染,存在有限的治疗选择.

Healthcare Associated Infections II: Preventive Measures
2.4K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

Steps in Outbreak Investigation
105
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Infection
7.7K
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...
