概括

城市化增加了野生鸟类中动物性传染病原体Campylobacter jejuni的多样性. 靠近人类息地与更多的病原体基因型和抗菌素耐药性 (AMR) 基因有关.

科学领域:

生态生态学生态生态学
微生物学微生物学
公共卫生公共卫生

背景情况:

人类活动,特别是城市化,正在显著改变全球生态系统.
城市化破坏了生态基质,增加了人类和野生动物之间的接触,这可以促进动物感染病原体的传播.
了解息地破坏如何影响病原体传播对于公共卫生至关重要.

研究的目的:

调查城市化对动物性肠道病原体Campylobacter jejuni.遗传多样性和抗菌素耐药性的影响.
确定靠近人类居住地是否会影响野生鸟群中C. jejuni基因型和抗菌素耐药性 (AMR) 基因的流行.

主要方法:

基因组分析700个C. jejuni从8个国家的30种鸟类中分离出来.
利用可扩展的通用线性模型方法来分析病原体基因组.
比较行为和生态特征,重点关注人类居住和病原体特征之间的关系.

主要成果:

发现靠近人类居住地促进了C. jejuni的血统多样性.
与非城市种群相比,城市野生鸟类携带的C. jejuni基因型多达三倍.
抗微生物耐药性 (AMR) C. jejuni菌株的流行率增加与城市地区的野生鸟类有关.

结论:

城市化对基因库的多样性和C. jejuni.等动物感染病原体的传播产生重大影响.
城市环境中的野生鸟类作为C. jejuni基因型和AMR基因更大的多样性储存库.
这项研究提供了量化证据,将城市化与动物性传染病原体多样性和AMR的增加联系起来,突出显示出严重的公共卫生问题.

Viral Recombination

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
