EXPLIFY RESPIRATORY PATHOGENS BY NEXT GENERATION SEQUENCING Limitations Negative results do not rule out viral, bacterial, or fungal infections. Targeted, PCR-based tests are generally more sensitive and are preferred when specific pathogens are suspected, especially for DNA viruses (Adenovirus, CMV, HHV6, HSV, and VZV), mycobacteria, and fungi. The analytical sensitivity of this test depends on the cellularity of the sample and the concentration of all microbes present. Analytical sensitivity is assessed using Internal Controls that are added to each sample. Sequencing data for Internal Controls is quantified. Samples with Internal Control values below the validated minimum may have reduced analytical sensitivity or contain inhibitors and are reported as ‘Reduced Analytical Sensitivity’. Additional respiratory pathogens to those reported cannot be excluded in samples with ‘Reduced Analytical Sensitivity’. Due to the complexity of next generation sequencing methodologies, there may be a risk of false-positive results. Contamination with organisms from the upper respiratory tract during specimen collection can also occur. The detection of viral, bacterial, and fungal nucleic acid does not imply organisms causing invasive infection. Results from this test need to be interpreted in conjunction with the clinical history, results of other laboratory tests, epidemiologic information, and other available data. Confirmation of positive results by an alternate method may be indicated in select cases. Validated Organisms BACTERIA Achromobacter -

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. -

The Value of UV for Legionella Control in Cooling Towers
The Value of UV for Legionella Control in Cooling Towers By Ytzhak Rozenberg, Assaf Lowentahl, Ph.D. Atlantium Technologies, [email protected], www.atlantium.com. ABSTRACT: Excessive growth of Legionella in cooling towers and water systems can cause significant negative health effects. Legionella and free-living amoebae may be present together and amoebae can act as a shield for Legionella, protecting it from traditional chemical disinfectants. Ultraviolet (UV) disinfection offers a non-chemical treatment approach that is effective for reducing biofilm potential in cooling tower water and provides reliable protection against the spread of Legionella and inac- tivation of amoebae. However, all UV technologies are not created equal; low-pressure (LP) and medium-pressure (MP) UV lamp technology have different effects on a microorganism’s mortality rate at different UV dose rates. In this comparative study, a proprietary MP lamp technology (Hydro-Optic™ [HOD]) manufactured by Atlantium Technologies was evaluated and determined to achieve 100% mortality of Entamoeba Histolytica (E. histolytica) at a dose of 8.8 mJ/cm2, while LP UV systems, even at a dose of 90 mJ/cm2, did not achieve 100% mortality. E. histolytica served as a Legionella host model in the study.

EVALUATION of the P45 MOBILE INTEGRATIVE ELEMENT and ITS ROLE IN
EVALUATION OF THE p45 MOBILE INTEGRATIVE ELEMENT AND ITS ROLE IN Legionella pneumophila VIRULENCE A Dissertation by LANETTE M. CHRISTENSEN Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Jeffrey D. Cirillo Committee Members, James Samuel Jon Skare Farida Sohrabji Head of Program, Warren Zimmer May 2018 Major Subject: Medical Sciences Copyright 2018 Lanette Christensen ABSTRACT Legionella pneumophila are aqueous environmental bacilli that live within protozoal species and cause a potentially fatal form of pneumonia called Legionnaires’ disease. Not all L. pneumophila strains have the same capacity to cause disease in humans. The majority of strains that cause clinically relevant Legionnaires’ disease harbor the p45 mobile integrative genomic element. Contribution of the p45 element to L. pneumophila virulence and ability to withstand environmental stress were addressed in this study. The L. pneumophila Philadelphia-1 (Phil-1) mobile integrative element, p45, was transferred into the attenuated strain Lp01 via conjugation, designating p45 an integrative conjugative element (ICE). The resulting trans-conjugate, Lp01+p45, was compared with strains Phil-1 and Lp01 to assess p45 in virulence using a guinea pig model infected via aerosol. The p45 element partially recovered the loss of virulence in Lp01 compared to that of Phil-1 evident in morbidity, mortality, and bacterial burden in the lungs at the time of death. This phenotype was accompanied by enhanced expression of type II interferon in the lungs and spleens 48 hours after infection, independent of bacterial burden. -

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. -
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. -
