概括

在法罗群岛,侵袭性B组链球菌 (GBS) 疾病的发病率正在上升. 这项研究提供了基因组和流行病学基线,表明未来的疫苗疗效和持续的青素敏感性.

科学领域:

微生物学微生物学
流行病学流行病学
基因组学就是基因组学.

背景情况:

乙组链球菌 (GBS) 在弱势群体中引起严重的入侵性疾病.
在像法罗群岛这样的孤立地区,侵入性GBS流行病学研究不足.

研究的目的:

为了建立一个基因组和流行病学基线侵入性GBS在法罗群岛从2009-2024.
评估GBS发病率,血清型,抗菌素耐药性和毒性因素的趋势.

主要方法:

在全国范围内对侵袭性GBS病例进行监测.
现型血型定型和抗菌素敏感性测试.
全基因组测序 (WGS),多位置序列类型 (MLST) 和病毒性基因分析.

主要成果:

GBS发病率显著增加,从每10万人口中的3.69增加到7.47.
主要的血清型是II,V,Ib和Ia. 所有的分离物都具有阿尔普家族蛋白质基因.
克隆复合体 (CC) 12占主导地位. 保持了对青素的敏感性;观察到一些对红红/克林达米的耐药性.

结论:

在法罗群岛,侵袭性GBS发病率正在增加.
基因组数据支持未来GBS疫苗的潜在疗效.
持续的基因组监测对于偏远人口的公共卫生和疫苗政策至关重要.

Factors Affecting the Risk of Infection

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
