Aquascreen® Legionella Species Aquascreen® Legionella Species AquaScreen® Legionella species qPCR Detection Kit INSTRUCTIONS FOR USE FOR USE IN RESEARCH AND QUALITY CONTROL Symbols Lot No. Order No. Expiry date Storage temperature Number of reactions Manufacturer INDICATION Legionella bacteria are ubiquitous in surface water and moist soil. Legionella are well known as opportunistic pathogens causing Legionnaires' disease and Pontiac fever. The incubation period is 20-10 days. An airborne transmission is unlikely; thus infections occur through inhalation of aer- osols bearing amoeba, the natural habitat of legionella. The AquaScreen® Legionella species qPCR Detection kit is specifically designed for the quantita- tive detection of Legionella species in water samples prepared with the AquaScreen® FastExtract kit. EXPLANATION OF THE TEST The AquaScreen® Legionella species kit utilizes qPCR for the quantitative detection of legionella in water samples. In contrast to time-consuming cell culture methods, the AquaScreen® ap- proach needs less than six hours including sample preparation and qPCR to reliably detect le- gionella bacteria. In addition, our qPCR assay is superior in terms of sensitivity and specificity as the assay only detects legionella species. The AquaScreen qPCR assay is insensitive to contamination with other bacterial genera. Also, the assay’s robustness is unsurpassed with linear detection up to 1 x 106 particles per sample. Thus there is no need for diluting sample material. The kit’s design complies with the requirements of AFNOR T90-471 and ISO/TS 12869:2012 TEST PRINCIPLE The PCR system targets a segment of the 16S rRNA region in the legionella genome. The target region is highly preserved within the genus Legionella. Clinically relevant species that are detect- ed are e.g. L. pneumophila (all serogroups), L. longbeachae, L. dumoffii, Fluoribacter bozemanii (L. bozemanii) and L. gormanii (see page 7 for the full list). Cross-reactivity to other waterborne microorganisms are not known. The kit contains the nucleotide dUTP instead of dTTP. The heat-labile Uracil-DNA Glycosylase (UNG) is suitable to prevent carry-over contamination between PCRs. This technique relies on the incorporation of deoxyuridine triphosphate (dUTP) during all amplified reactions and the pre- treatment of all successive PCR mixtures with the heat-labile UNG. UNG is not included. The L. species mix contains all required primer, probes, dNTPs and Taq polymerase. 33-2025/2100/2250 Product Version 2 | Document Version 2 1 REAGENTS Each kit contains reagents for 25, 100 or 250 reactions.

SPECIMEN For sample preparation please see the AquaScreen® FastExtract instructions for users. Extracted samples must be stored at < -18 °C for up to one year. Repeated freeze/thaw must be avoided as it is detrimental to the DNA’s integrity. 33-2025/2100/2250 2 Product Version 2 | Document Version 2 PRECAUTIONS The AquaScreen qPCR kit is for research use only. The kit should be used by trained laboratory staff only. All samples should be considered as potentially infectious and handled with all due care and attention. Always wear suitable lab coat and disposable gloves. This kit does not contain hazardous substances. Remnants can be discarded according to local regulations. IMPORTANT NOTES These instructions must be understood to successfully use the AquaScreen® qPCR Detec- tion kit. The reagents supplied should not be mixed with reagents from different LOT and used as an integral unit. The reagents of the kit must not be used beyond their shelf life. Follow the exact protocol. Any deviation may affect the test method and can affect the re- sults. PCR inhibition is likely to be caused by the sample matrix, or, in case of extracted DNA, caused by the elution buffer. Thus we recommend our AquaScreen® FastExtract kit for sam- ple preparation. Any other DNA extraction kit needs to be qualified. It is important to include control samples on a regular basis to monitor the reliability of your results. Positive and negative controls are essential in case of troubleshooting. The control samples must be processed in the same manner as the test samples. You may want to include other laboratory specific control samples such as high, median and low DNA level (e.g. 3x LOD95). Please note that Minerva Biolabs also offers to participate in external quality control programs. APPENDIX Limited Product Warranty This warranty limits our liability for replacement of this product.

  • 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.

Next generation sequencing (NGS) has led to many discoveries about viruses, but three notable challenges exist in applying NGS to study the viromes of complex matrices. Despite being the most highly abundant members of most communities, viral nucleic acids are a small portion of the total nucleic acids. Efficient viral enrichment methods are needed. Viral isolation and enrichment methods are not equally efficient. Optimized methods are needed to quantitatively compare viral representation across samples. Viral genomes are mosaic with a high mutation rate and, therefore, difficult to assemble with short reads produced with Illumina sequencing technologies. Supplemental sequencing technologies need to be explored. To address these challenges, our research advances NGS methods with a quantitative sequencing approach on the isolated virus fraction from wastewater with a combination of long and short read sequencing. Wastewater viruses are concentrated with tangential and dead-end ultrafiltration 575-fold in influent and 1,150-fold in effluent. The viruses are purified with chloroform to lyse cells and DNase to degrade extra-viral DNA. The concentration and purification protocol recovered approximately half of the viral DNA while removing 4-logs of 16S rRNA. For quantitative comparisons, 86 dsDNA and 5 ssDNA internal standards were spiked into samples at 1% of the total DNA concentration prior to simultaneously sequencing ssDNA and dsDNA on Illumina NovaSeq.

  • The Microbial Ecology and Horticultural Sustainability of Organically and Conventionally Managed Apples
    ABSTRACT Title of Document: THE MICROBIAL ECOLOGY AND HORTICULTURAL SUSTAINABILITY OF ORGANICALLY AND CONVENTIONALLY MANAGED APPLES. Andrea R. Ottesen, PhD, 2008 Directed By: Professor, Dr. Christopher S. Walsh, Plant Sciences and Landscape Architecture Objectives Organically and conventionally managed apple trees (Malus domestica Borkh) were evaluated for three growing seasons (2005-2007) to examine the impact of organic and conventional pesticide applications on the microbial ecology of phyllosphere and soil microflora. An important objective was to establish if organic or conventional selection pressures contribute to an increased presence of enteric pathogens in phyllosphere microflora. The horticultural and economic sustainability of the organic crop was also compared to the conventional crop with regard to fruit yield and input costs. Methods Microbial populations from phyllosphere and soil environments of apple trees were evaluated using clone libraries of 16S rRNA gene fragments. Clones were sequenced and software was used to assess diversity indices, identify shared similarities and compute statistical differences between communities. These measurements were subsequently used to examine treatment effects on the microbial libraries. Phyllosphere Results Eight bacterial phyla and 14 classes were found in this environment. A statistically significant difference between organically and conventionally managed phyllosphere bacterial microbial communities was observed at four of six sampling time points. Unique phylotypes were found associated with each management treatment but no increased human health risk could be associated with either treatment with regard to enteric pathogens. Soil Results Seventeen bacterial phyla spanning twenty-two classes, and two archaeal phyla spanning eight classes, were seen in the 16S rRNA gene libraries of organic and conventional soil samples.
