Today, cyanobacteria, as the first photosynthetic microorganisms, play an undeniable role in ecosystems and global markets. In this research, the biomass and photosynthetic pigment production under environmental and nutritional factors in C...
Quantitative transcriptomic and metabolic analyses reveal the roles of RpoS and Crp in the acid resistance system 1 in Escherichia coli [0.03%]
定量转录组和代谢分析揭示了RpoS和Crp在大肠杆菌酸抵抗系统1中的作用
Wenbin Zhang,Liang Zhang,Jinxin Xu et al.
Wenbin Zhang et al.
Foodborne pathogens exploit acid resistance (AR) mechanisms to survive harsh environments, such as the stomach, increasing contamination risk. While the sigma factor RpoS and cyclic AMP receptor protein (Crp) are known mediators of AR, thei...
Acclimation temperature influences phage susceptibility in a toxin-producing strain of Microcystis aeruginosa [0.03%]

Kennedi M Hambrick,Laura E Smith,Robbie M Martin et al.
Kennedi M Hambrick et al.
Microcystis aeruginosa is a freshwater cyanobacterium known for its role in the formation of harmful algal blooms. However, less well characterized are the host-phage interactions that occur in these toxic blooms. Here, we describe the rela...
Reliable delineation of Clostridioides difficile and related members of the family Peptostreptococcaceae using phylogenomics and spore coat protein-specific molecular markers [0.03%]
基于基因组和孢子衣蛋白特异性分子标记的可靠区分艰难梭菌及相关肽链球菌科成员的方法
Jianying Han,Yannan Li,Yuxi Xu et al.
Jianying Han et al.
Traditional bacterial classification relies on phenotypic traits (e.g., morphology and metabolic profiles), but these methods lack resolution for closely related taxa and are biased by culture conditions. While 16S rRNA gene sequencing is a...
Direct interaction between avian pathogenic Escherichia coli and H9N2 avian influenza virus promotes bacterial adhesion during their infections [0.03%]
致病性鸡源大肠杆菌与H9N2禽流感病毒的直接互作促进其感染中的细菌黏附作用

Effective diagnosis for pulmonary tuberculosis (TB) remains challenging, especially in the face of no symptom and no sputum. A tongue swab has become a promising alternative to sputum collection. We aimed to optimize the tongue swab process...
PA5201 represses type III secretion system by binding to the P exsC promoter in Pseudomonas aeruginosa [0.03%]
PA5201通过结合铜绿假单胞菌PexsC启动子抑制III型分泌系统
Lepeng Wang,Chenyu Shen,Liwen Yin et al.
Lepeng Wang et al.
The type III secretion system (T3SS) is a major virulence determinant in Pseudomonas aeruginosa, which is activated by the master regulator ExsA. exsA is transcribed from two distinct promoters: its operon promoter PexsC and its own promote...
