“…Pantoea and Tatumella differ markedly in terms of KEGG's “Environmental Information Processing” functional category, which includes all signaling and membrane transport pathways (Kanehisa et al, 2002 ). Various ABC transporters (Nohno et al, 1986 ; Scripture et al, 1987 ; Gowrishankar, 1989 ; Stirling et al, 1989 ; Kehres and Hogg, 1992 ; Kempf and Bremer, 1995 ; Van der Ploeg et al, 1996 ; Walshaw et al, 1997 ; Kappes et al, 1999 ; Ko and Smith, 1999 ; Hosie and Poole, 2001 ; Schneider, 2001 ; Vanneste et al, 2001 ; Suzuki et al, 2005 ; Javaux et al, 2007 ; Novikova et al, 2007 ; Metlitskaya et al, 2009 ) and phosphotransferase systems (PTSs) (Hall and Xu, 1992 ; Dahl et al, 2004 ; Uehara et al, 2006 ; Jaeger and Mayer, 2008 ; Plumbridge, 2009 ) were differentially present in the two genera. Among the various ABC transporters identified only in Pantoea , one has been associated with susceptibility to microcin C in the absence of a microcin C-specific efflux pump (Metlitskaya et al, 2009 ), which is part of a group of antibiotic produced by certain Enterobacteriaceae (Vanneste et al, 2001 ; Metlitskaya et al, 2009 ).…”

Bacteriologists have strived toward attaining a natural classification system based on evolutionary relationships for nearly 100 years. In the early twentieth century it was accepted that a phylogeny-based system would be the most appropriate, but in the absence of molecular data, this approach proved exceedingly difficult. Subsequent technical advances and the increasing availability of genome sequencing have allowed for the generation of robust phylogenies at all taxonomic levels. In this study, we explored the possibility of linking biological characters to higher-level taxonomic groups in bacteria by making use of whole genome sequence information. For this purpose, we specifically targeted the genus Pantoea and its four main lineages. The shared gene sets were determined for Pantoea, the four lineages within the genus, as well as its sister-genus Tatumella. This was followed by functional characterization of the gene sets using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. In comparison to Tatumella, various traits involved in nutrient cycling were identified within Pantoea, providing evidence for increased efficacy in recycling of metabolites within the genus. Additionally, a number of traits associated with pathogenicity were identified within species often associated with opportunistic infections, with some support for adaptation toward overcoming host defenses. Some traits were also only conserved within specific lineages, potentially acquired in an ancestor to the lineage and subsequently maintained. It was also observed that the species isolated from the most diverse sources were generally the most versatile in their carbon metabolism. By investigating evolution, based on the more variable genomic regions, it may be possible to detect biologically relevant differences associated with the course of evolution and speciation.

“…Tau metabolism. In relation to Tau metabolism, cysteine or sulfate deficiency leads to tauD (or an orthologue) being essential for growth of E. coli (132,133). The presence of TauD leads to the production of sulfite for use as a source of sulfur by catalyzing the hydroxylation of taurine alpha-(2-aminoethanesulfonic acid) in the sulfonate.…”

Mechanisms of Bacterial Tolerance and Persistence in the Gastrointestinal and Respiratory Environments

SUMMARYPathogens that infect the gastrointestinal and respiratory tracts are subjected to intense pressure due to the environmental conditions of the surroundings. This pressure has led to the development of mechanisms of bacterial tolerance or persistence which enable microorganisms to survive in these locations. In this review, we analyze the general stress response (RpoS mediated), reactive oxygen species (ROS) tolerance, energy metabolism, drug efflux pumps, SOS response, quorum sensing (QS) bacterial communication, (p)ppGpp signaling, and toxin-antitoxin (TA) systems of pathogens, such as , spp., spp., spp., , spp., spp., spp., and , all of which inhabit the gastrointestinal tract. The following respiratory tract pathogens are also considered:, ,, , and Knowledge of the molecular mechanisms regulating the bacterial tolerance and persistence phenotypes is essential in the fight against multiresistant pathogens, as it will enable the identification of new targets for developing innovative anti-infective treatments.

“…Bacteria have developed several molecular mechanisms that enable them to survive under stress conditions in different environments. The general stress response (RpoS) (Battesti et al, 2011), tolerance to reactive oxygen species (ROS) (Zhao and Drlica, 2014; Van den Bergh et al, 2017), energy metabolism (cytochrome bd complex) (Korshunov and Imlay, 2010) and Tau metabolism (Javaux et al, 2007), drug efflux pumps (Blanco et al, 2016), SOS response (Baharoglu and Mazel, 2014), (p)ppGpp signaling under starvation conditions (Hauryliuk et al, 2015), toxin-antitoxin (TA) systems (Wood et al, 2013) and quorum sensing (QS), which we will discuss in detail in this review, are the main molecular mechanisms of tolerance and bacterial persistence (Harms et al, 2016; Trastoy et al, 2018).…”

Relationship Between Quorum Sensing and Secretion Systems

Quorum sensing (QS) is a communication mechanism between bacteria that allows specific processes to be controlled, such as biofilm formation, virulence factor expression, production of secondary metabolites and stress adaptation mechanisms such as bacterial competition systems including secretion systems (SS). These SS have an important role in bacterial communication. SS are ubiquitous; they are present in both Gram-negative and Gram-positive bacteria and in Mycobacterium sp. To date, 8 types of SS have been described (T1SS, T2SS, T3SS, T4SS, T5SS, T6SS, T7SS, and T9SS). They have global functions such as the transport of proteases, lipases, adhesins, heme-binding proteins, and amidases, and specific functions such as the synthesis of proteins in host cells, adaptation to the environment, the secretion of effectors to establish an infectious niche, transfer, absorption and release of DNA, translocation of effector proteins or DNA and autotransporter secretion. All of these functions can contribute to virulence and pathogenesis. In this review, we describe the known types of SS and discuss the ones that have been shown to be regulated by QS. Due to the large amount of information about this topic in some pathogens, we focus mainly on Pseudomonas aeruginosa and Vibrio spp.
