(Submitter supplied) Ralstonia solanacearum, recognized as a pervasive plant pathogen causing lethal wilt disease in over 450 plant species worldwide, represents a substantial threat to economically vital crops including tomato, chili, and eggplant. Within R. solanacearum, pehR serves as a transcriptional regulator, forming part of the pehSR two-component regulatory system. This system governs the production of polygalacturonase (PG), a crucial extracellular enzyme involved in plant cell wall degradation and bacterial wilt development. more...

(Submitter supplied) Biofilm lifestyle is critical for bacterial pathogens to colonize and protect themselves from host immunity and antimicrobial chemicals in plants and animals. The formation and regulation mechanism of phytobacterial biofilm are still obscure. Here, we found that Ralstonia solanacearum Resistance to ultraviolet C (RuvC) is highly abundant in biofilm and positively regulates pathogenicity by governing systemic movement in tomato xylem. more...

(Submitter supplied) Asymptomatic colonization of the upper respiratory tract is a common trait of the two exclusive human pathogens, Neisseria gonorrhoeae and Neisseria meningitidis. In vivo models of pathogenic neisserial infections are heterologous systems that permit short-term persistence but do not fully recapitulate infections in humans. Studying Neisseria musculi (Nmus), an oral commensal, in laboratory mice allows investigation of Neisseria-host interactions that avoids host restriction barriers. more...

(Submitter supplied) The cadmium-resistant Cupriavidus sp. E324 strain has been previously shown to have a high potential for use in cadmium (Cd) remediation, due to its high capacity for cadmium bioaccumulation. According to the comparative genomic analysis, the E324 strain was most closely related to C. nantongensis X1 T , indicating that the E324 strain should be re-identified as C. nantongensis. To unravel the Cd tolerance mechanisms of C. more...

(Submitter supplied) Plant pathogens require lethal virulence factors, susceptible hosts, and optimal environmental conditions for disease establishment. High soil salinity, exacerbated by climate change, significantly impacts agro-biological ecosystems.

(Submitter supplied) The classical bordetellae (Bordetella pertussis, B. parapertussis, and B. bronchiseptica) are obligate aerobes that use only oxygen as their terminal electron acceptor for electron transport-coupled oxidative phosphorylation. Therefore, access to oxygen is critical for these bacteria to survive. To better understand how B. bronchiseptica changes its gene regulation when faced with different levels of oxygen, we grew liquid cultures of B. more...

(Submitter supplied) Bacterial pathogens exhibit a remarkable ability to persist and thrive in diverse ecological niches. Understanding the mechanisms enabling their transition between environments is crucial to control dissemination and potential disease outbreaks.

(Submitter supplied) Volatilization of lower-chlorinated polychlorinated biphenyls (LC-PCBs) from sediment poses health threats to nearby communities and ecosystems. Biodegradation combined with black carbon (BC) materials is an emerging approach to remove PCBs from sediment, but development of aerobic biofilms on BC for long-term, sustained LC-PCBs remediation is poorly understood. This work aimed to characterize cell enrichment and activity of biphenyl- and benzoate-grown Paraburkholderia xenovorans strain LB400 on various BCs. more...

(Submitter supplied) Carbon catabolite repression (CCR) is a gene regulation process that allows bacteria to use carbon-energy sources in a hierarchical manner. Thus, the presence of a preferred sugar, usually D-glucose, results in downregulation of genes participating in the transport and catabolic pathways of secondary carbon sources. Further, CCR controls the expression of global regulators that control expression of many genes involved in multiple aspects of bacterial physiology such as stress response proteins and virulence factors. more...
