By analyzing and extending earlier work on the concept of pathogen, we propose pathogenicity (or virulence) should be viewed as a dynamical feature of an interaction between a host and microbes. 展开 关键词: ecology evolution disease infection process virulence ...
Genome research: Evolution of Streptococcus pneumoniae - What is a pathogen? The genome of the commensal Streptococcus mitis B6 helps to reveal the evolution of its close pathogenic relative Streptococcus pneumoniae. R. Brückner,D. Denapaite,B. Henrich,... - 《Biospektrum》 被引量: 0发表: 201...
PathogenicityVirulenceThe question ''what is a pathogen?'' derives from pathogen-centered views of microbial pathogenesis that invoke microbial characteristics to explain virulence. However, virulence cannot be an independent microbial variable since it is only expressed in a susceptible host. Hence, ...

What is a pathogen? Question: What is a pathogen? Normal Flora Normal flora are the good microorganisms that live inside the gut. These microorganisms are not seen as antigens by the immune system, do not normally cause illness, and can actually help us to fight off pathogens. By competing...
While sequencing of the human genome surprised us with how many protein-coding genes there are, it did not fundamentally change our perspective on what a gene is. In contrast, the complex patterns of dispersed regulation and pervasive transcription uncovered by the ENCODE project, together with non...
