Studies frequently focus on the abundant number of virulence factors present in this genus. However, what is often overlooked is the role of secondary metabolites from Legionella. Following whole genome sequencing, we assembled and annotated the Legionella parisiensis DSM 19216 genome. Together with 14 other members of the Legionella, we performed comparative genomics and analysed the secondary metabolite potential of each strain. We found that Legionella contains a huge variety of biosynthetic gene clusters (BGCs) that are potentially making a significant number of novel natural products with undefined function. Surprisingly, only a single Sfp-like phosphopantetheinyl transferase is found in all Legionella strains analyzed that might be responsible for the activation of all carrier proteins in primary (fatty acid biosynthesis) and secondary metabolism (polyketide and non-ribosomal peptide synthesis). Using conserved active site motifs, we predict Submitted 29 June 2016 some novel compounds that are probably involved in cell-cell communication, Accepted 25 October 2016 Published 24 November 2016 differing to known communication systems. -

To address this issue, genome sequences of 32 Roseobacter isolates were analyzed for patterns in genome characteristics, gene inventory, and individual gene/ pathway distribution using three predictive frameworks: phylogenetic relatedness, lifestyle strategy and environmental origin of the isolate. For the first framework, a phylogeny containing five deeply branching clades was obtained from a concatenation of 70 conserved single-copy genes. Somewhat surprisingly, phylogenetic tree topology was not the best model for organizing genome characteristics or distribution patterns of individual genes/pathways, although it provided some predictive power. The lifestyle framework, established by grouping isolates according to evidence for heterotrophy, photoheterotrophy or autotrophy, explained more of the gene repertoire in this lineage. -
Microbial Diversity Under Extreme Euxinia: Mahoney Lake, Canada V

A dense plate of phototrophic purple sulfur bacteria is found at the chemocline, but to date the rest of the Mahoney Lake microbial ecosystem has been underexamined. In particular, the microbial community that resides in the aphotic hypolimnion and ⁄ or in the lake sediments is unknown, and it is unclear whether the sulfate reducers that supply sulfide for phototrophy live only within, or also below, the plate. Here we profiled distribu- tions of 16S rRNA genes using gene clone libraries and PhyloChip microarrays. Both approaches suggest that microbial diversity is greatest in the hypolimnion (8 m) and sediments. Diversity is lowest in the photosynthetic plate (7 m). Shallower depths (5 m, 7 m) are rich in Actinobacteria, Alphaproteobacteria, and Gammaproteo- bacteria, while deeper depths (8 m, sediments) are rich in Crenarchaeota, Natronoanaerobium, and Verrucomi- crobia. The heterogeneous distribution of Deltaproteobacteria and Epsilonproteobacteria between 7 and 8 m is consistent with metabolisms involving sulfur intermediates in the chemocline, but complete sulfate reduction in the hypolimnion. -

Horizontal Operon Transfer, Plasmids, and the Evolution of Photosynthesis in Rhodobacteraceae
The ISME Journal (2018) 12:1994–2010 https://doi.org/10.1038/s41396-018-0150-9 ARTICLE Horizontal operon transfer, plasmids, and the evolution of photosynthesis in Rhodobacteraceae 1 2 3 4 1 Henner Brinkmann ● Markus Göker ● Michal Koblížek ● Irene Wagner-Döbler ● Jörn Petersen Received: 30 January 2018 / Revised: 23 April 2018 / Accepted: 26 April 2018 / Published online: 24 May 2018 © The Author(s) 2018. This article is published with open access Abstract The capacity for anoxygenic photosynthesis is scattered throughout the phylogeny of the Proteobacteria. Their photosynthesis genes are typically located in a so-called photosynthesis gene cluster (PGC). It is unclear (i) whether phototrophy is an ancestral trait that was frequently lost or (ii) whether it was acquired later by horizontal gene transfer. We investigated the evolution of phototrophy in 105 genome-sequenced Rhodobacteraceae and provide the first unequivocal evidence for the horizontal transfer of the PGC. The 33 concatenated core genes of the PGC formed a robust phylogenetic tree and the comparison with single-gene trees demonstrated the dominance of joint evolution. The PGC tree is, however, largely incongruent with the species tree and at least seven transfers of the PGC are required to reconcile both phylogenies. 1234567890();,: 1234567890();,: The origin of a derived branch containing the PGC of the model organism Rhodobacter capsulatus correlates with a diagnostic gene replacement of pufC by pufX. The PGC is located on plasmids in six of the analyzed genomes and its DnaA- like replication module was discovered at a conserved central position of the PGC. A scenario of plasmid-borne horizontal transfer of the PGC and its reintegration into the chromosome could explain the current distribution of phototrophy in Rhodobacteraceae. -

Aquascreen® Legionella Species Qpcr Detection Kit
AquaScreen® Legionella species qPCR Detection Kit INSTRUCTIONS FOR USE FOR USE IN RESEARCH AND QUALITY CONTROL Symbols Lot No. Cat. No. Expiry date Storage temperature Number of reactions Manufacturer INDICATION The AquaScreen® Legionella species qPCR Detection kit is specifically designed for the quantitative detection of several Legionella species in water samples prepared with the AquaScreen® FastExt- ract kit. Its design complies with the requirements of AFNOR T90-471 and ISO/TS 12869:2012. Legionella are ubiquitous bacteria in surface water and moist soil, where they parasitize protozoa. The optimal growth temperature lies between +15 and +45 °C, whereas these gram-negative bacteria are dormant below 20 °C and do not survive above 60 °C. Importantly, Legionella are well-known as opportunistic intracellular human pathogens causing Legionnaires’ disease and Pontiac fever. The transmission occurs through inhalation of contami- nated aerosols generated by an infected source (e.g. human-made water systems like shower- heads, sink faucets, heaters, cooling towers, and many more). In order to efficiently prevent Legionella outbreaks, water safety control measures need syste- matic application but also reliable validation by fast Legionella testing. TEST PRINCIPLE The AquaScreen® Legionella species Kit uses qPCR for quantitative detection of legionella in wa- ter samples. In contrast to more time-consuming culture-based methods, AquaScreen® assays need less than six hours including sample preparation and qPCR to reliably detect Legionella. Moreover, the AquaScreen® qPCR assay has proven excellent performance in terms of specificity and sensitivity: other bacterial genera remain undetected whereas linear quantification is obtai- ned up to 1 x 106 particles per sample, therefore requiring no material dilution. -
Genomic Analyses of Two Alteromonas Stellipolaris Strains Reveal Traits
www.nature.com/scientificreports OPEN Genomic analyses of two Alteromonas stellipolaris strains reveal traits with potential Received: 7 August 2018 Accepted: 27 November 2018 biotechnological applications Published: xx xx xxxx Marta Torres1,2,3, Kar-Wai Hong4, Teik-Min Chong4, José Carlos Reina1, Kok-Gan Chan 4,5, Yves Dessaux3 & Inmaculada Llamas 1,2 The Alteromonas stellipolaris strains PQQ-42 and PQQ-44, previously isolated from a fsh hatchery, have been selected on the basis of their strong quorum quenching (QQ) activity, as well as their ability to reduce Vibrio-induced mortality on the coral Oculina patagonica. In this study, the genome sequences of both strains were determined and analyzed in order to identify the mechanism responsible for QQ activity. Both PQQ-42 and PQQ-44 were found to degrade a wide range of N-acylhomoserine lactone (AHL) QS signals, possibly due to the presence of an aac gene which encodes an AHL amidohydrolase. In addition, the diferent colony morphologies exhibited by the strains could be related to the diferences observed in genes encoding cell wall biosynthesis and exopolysaccharide (EPS) production. The PQQ-42 strain produces more EPS (0.36 g l−1) than the PQQ-44 strain (0.15 g l−1), whose chemical compositions also difer. Remarkably, PQQ-44 EPS contains large amounts of fucose, a sugar used in high-value biotechnological applications. Furthermore, the genome of strain PQQ-42 contained a large non- ribosomal peptide synthase (NRPS) cluster with a previously unknown genetic structure. The synthesis of enzymes and other bioactive compounds were also identifed, indicating that PQQ-42 and PQQ-44 could have biotechnological applications. -
Immunoproteomic Identification of Biomarkers for Diagnosis of Legionellosis
Immunoproteomic identification of biomarkers for diagnosis of legionellosis Submitted in total fulfilment of the requirements for the degree of Doctor of philosophy by Kaylass Poorun Department of Chemistry and Biotechnology Faculty of Science, Engineering and Technology Swinburne University of Technology Australia 2014 Abstract Abstract Legionellosis, a disease with significant mortality and morbidity rates, is considered to be the second most frequent cause of severe community-acquired pneumonia. It is difficult to distinguish from other types of pneumonia due to similar clinical manifestations. Several studies have demonstrated the inadequacies of current diagnostic tests for confirming Legionella infections. This study was aimed at identifying biomarkers that can be used in an improved test. A comparative proteomic analysis, using DIGE, was carried out between L. pneumophila ATCC33152 and L. longbeachae NSW150 and D4968 isolates. While many homologous proteins were found to be commonly expressed, numerous others were identified to be differentially expressed under similar in vitro conditions suggesting that the two species have different lifestyles and infection strategies. The bacterial immunoglobulin domain containing protein, found to share sequence homology to Type V secretion proteins intimin and invasin, is not known to be present in Legionella. Human sera containing antibodies against Legionella from a set of blind samples were identified by ELISA. Downstream analyses revealed that diverse immunogens may be responsible for eliciting immune response in different Legionella species which in turn show little to no congeneric cross-reactivity. To the best of our knowledge, this is a unique finding not previously reported. Several serological diagnostic tests currently in use do not include many Legionella species in their testing panel, which may be a reason for many Legionella species being under-reported. -
