Tissue tropisms in group A Streptococcus: what virulence factors distinguish pharyngitis from impetigo strains? 来自 Semantic Scholar 喜欢 0 阅读量: 30 作者: DE Bessen 摘要: Purpose of review: Group A streptococci (GAS) are a common cause of pharyngitis and impetigo, and distinct throat strains ...
increased inflammation and destruction of the supporting tissues for the teeth can occur. These organisms include Porphyromonas gingivalis which produces many virulence factors that can promote local tissue destruction around the teeth. In addition, P. gingivalis can enter the blood stream and either act...
In the last decade many studies have been performed on the virulence of Newcastle disease virus (NDV). This is mainly due to the development of reverse genetics systems which made it possible to genetically modify NDV and to investigate the contribution
Bacteria: Bacteria are single-celled organisms that belong to a separate domain of life. They are prokaryotic, meaning they do not have membrane-bound organelles. There are the most abundant forms of life on the planet. Answer and Explanation:1 ...
This relationship is affected by numerous parameters for the pathogen (strain, virulence, cell history), person consuming the pathogen (age, immune status) and food matrix (fat level, acidity). The setting of ALOP and FSO are ultimately value judgments, not scientific calculations. Factors in ...
How does tuberculosis affect the organ system? Is TB a viral disease? What is the etiology of cellulitis? What is the disease process of pneumonia? What is the causative agent of plague? What is virulence factors of TB? What is a zoonotic viral disease?
How does the complement system cause bacterial lysis? What are the virulence factors of Francisella tularensis? How does coagulase enhance the virulence of an organism? Why is virulence important? What is the causative agent of candidiasis?
