Bacteria use two-component systems (TCSs) to sense and respond to their environments. Free-living bacteria usually contain dozens of TCSs, each of them responsible for sensing and responding to a different range of signals. Differences in the content of two-component systems are related with the capacity of the bacteria to colonize different niches or improve the efficiency to grow under the conditions of the existing niche. This review highlights differences in the TCS content between Staphylococcus aureus and Staphylococcus saprophyticus as a case study to exemplify how the ability to sense and respond to the environment is relevant for bacterial capacity to colonize and survive in/on different body surfaces.

两组分感觉网络对葡萄球菌形态的影响。

细菌使用两组分系统（TCS）来感知和响应其环境。自由生存的细菌通常包含数十个TCS，每个TCS负责感测和响应不同范围的信号。两组分系统含量的差异与细菌在不同生态位定殖或提高在现有生态位条件下生长的能力有关。这篇综述突出了金黄色葡萄球菌和腐生葡萄球菌之间TCS含量的差异，以此为例来说明感知和响应环境的能力与细菌在不同体表内/表面定殖和生存的能力如何相关。
