Detection of total and faecal coliforms in the oysters Resource Report Resource Website |
Sade Aisha Folashade John, Patrick E. Akpaka, Chandrashekhar Unakal, Arvind Kurhade, Angel Justiz-Vaillant | DOI:10.17504/protocols.io.bj6hkrb6 | University of the West Indies, [email protected] | Enterobacteriaceae the leading cause of gastroenteritis. These gram- negative bacteria from species like Escherichia, Shigella, Salmonella, Vibrio and Helicobacter etc are among those that cause severe disease in consumers, especially those that indulge in uncooked seafood. Oysters have been shown to harbour these pathogenic organisms, which pose a major health risk. Numerous outbreaks of gastroenteritis due to oyster consumption have been reported worldwide because of the enteric bacteria as well as viral pathogen contaminationThis research was conducted to identify the Enterobacteriaceae present in oysters sold by vendors in Trinidad. During a five-month period (the rainy season, May - September), a total of 156 oyster samples (comprising 104 oysters samples and 52 water samples of the prepared, unprepared oyster cocktails plus the water used by vendors) were analysed. These samples were collected from roadside vendors operating near to the coastal line of the Western part of Trinidad These were processed at the microbiology unit of the Department of Para-clinical Sciences of the University of the West Indies, St. Augustine using standard microbiology techniques. The antibiotic susceptibility profiles of the recovered organisms were performed using the Kirby Bauer method for the following antibiotics- Tetracycline, Ampicillin, Trimethoprim-Sulfamethoxazole, Cefuroxime and Ceftazidime. The SPSS 21 programme was used to analyse the biometric data and a chi-square test was used to determine if there was any significant difference between the kinds of preparation cocktails with respect to the coliform and organisms found.Results of the 104 oyster samples tested, 112 isolates were obtained, 13.4% (15/112) were E.coli of which 0.1% (1/15) was the 0157:H7 strain; 72.3% (81/112) were Shigella species of which 27.2% (22/81) were Shigella dysenteriae; 14.3% (16/112) were Salmonella species of which 25% (4/16) were Salmonella cubana. The susceptibility profiles of the organisms revealed that 86.5% of Shigella, 100% of E.coli and 93.7% of the Salmonella were resistant to multiple antibiotics. With the recovery of these organisms from these samples, the health of the Trinidadian and foreign consumers of mangrove oysters is at risk particularly from Shigella, E.coli and Salmonella species. As a result, there should be an increased need for public awareness as well as regulations by the Ministry of Health to be made so that illness from these hazardous Enterobacteriaceae can be prevented. | University of the West Indies St. Augustine, University of the West Indies St. Augustine, University of the West Indies St. Augustine, University of the West Indies St. Augustine, University of the West Indies St. Augustine | 1 | 2020 | Sade Aisha Folashade John, Patrick E.

Standard method for microCT-based additive manufacturing quality control 3: surface roughness Resource Report Resource Website |
Anton Du Plessis | DOI:10.17504/protocols.io.sbweape | The use of microCT of 10 mm coupon samples produced by AM has the potential to provide useful information of mean density and detailed porosity information of the interior of the samples. In addition, the same scan data can be used to provide surface roughness analysis of the as-built surfaces of the same coupon samples. This can be used to compare process parameters or new materials. While surface roughness is traditionally done using tactile probes or with non-contact interferometric techniques, the complex surfaces in AM are sometimes difficult to access and may be very rough, with undercuts and may be difficult to accurately measure using traditional techniques which are meant for smoother surfaces. This standard workflow demonstrates on a coupon sample how to acquire surface roughness results, and compares the results from roughly the same area of the same sample with tactile probe results. The same principle can be applied to more complex parts, keeping in mind the resolution limit vs sample size of microCT. | University of Stellenbosch | https://www.liebertpub.com/doi/10.1089/3dp.2018.0060 | 1 | 2018 | Anton Du Plessis 2018.

Tissue Preparation for Spatial Metabolomics Resource Report Resource Website |
Guanshi Zhang, Dusan Velickovic, Annapurna Pamreddy, Jessica Lukowski, Theodore Alexandrov, Chris Anderton, Kumar Sharma | DOI:10.17504/protocols.io.bcraiv2e | KPMP, Metabolomics Protocols & Workflows | Mass spectrometry imaging (MSI) is a cutting-edge molecular technology that enables simultaneous analysis of multiple molecular components directly from single cells, tissues, and organs. For MSI, cryosections are prepared from flash-frozen tissue and mounted on a contuctive glass slide. We use matrix-assisted laser desorption ionization (MALDI)-MSI, where tissue sections are coated with a MALDI matrix in order to facilitate laser ionization and detection of metabolites with mass spectrometry. We do it using an automated robotic sprayer (TM-Sprayer) with 2,5- dihydroxybenzoic acid (DHB) MALDI matrix for positive ion mode analysis, N-(1-naphthyl) ethylenediamine hydrochloride (NEDC) for negative ion mode analyses, or 1,5-Diaminonaphthalene (DAN) for dual-polarity analysis, prior to being loaded into the MALDI-Q Exactive HF-X Orbitrap-MSI or MALDI-FTICR-MSI for untargeted metabolomics analysis. We have optimized a method for matrix application to maximize analyte extraction from tissue and increase MALDI sensitivity and to create the most homogenous matrix films possible for best lateral resolution of lipids. A key capacity that will be critical for scale-up in KPMP is the use of a TM-sprayer robotic sprayer for MALDI matrix application. This will make inter-lab studies viable, by increasing the reproducibility of sample preparation and is currently in use at UTHSA and PNNL. Our lipid extraction protocol for LC-MS/MS is a robust and universal protocol for single-sample integrative proteomics, metabolomics, and lipidomics analyses (see citation). | University of Texas Health San Antonio, Pacific Northwest National Laboratory, University of Texas Health San Antonio, Pacific Northwest National Laboratory, European Molecular Biology Laboratory, Pacific Northwest National Laboratory, University of Texas Health San Antonio | 1 | 2020 | Guanshi Zhang, Dusan Velickovic, Annapurna Pamreddy, Jessica Lukowski, Theodore Alexandrov, Chris Anderton, Kumar Sharma 2020.

Illuminated Orbital Shaker for Microalgae Culture Resource Report Resource Website |
Jakub Nedbal | DOI:10.17504/protocols.io.8wuhxew | Microalgae are grown for the research on photosynthesis, biotechnology, and water-environment ecology. Specialized laboratories typically use calibrated commercial equipment, which agitates the microalgae culture by shaking or bubbling, controls the irradiance, temperature, and CO2 content. Such commercial incubators may be out of reach for some laboratories, like those not specializing in microalgae research, teaching laboratories, or laboratories in low resource settings. Our research uses microalgae cultures during the development and validation of advanced microscopy techniques. We lacked access to and the budget for a commercial incubator. We solved the problem by building a stand-alone orbital shaking incubator with an in-built variable light source and a 24-hour timer. The shaker features a homogeneously illuminated growth area of 20 cm × 15 cm, which is suitable for three T75 tissue culture flasks or four 100 ml Erlenmeyer flasks. The overall material cost was around £300 and assembly time of about two days. We tested the shaker with fresh-water microalgae Desmodesmus quadricauda and Chlorella vulgaris. Both microalgae cultures have been grown continuously for seven months in the incubator. We studied their growth under different light conditions to validate the function of the shaker. The protocol outlines the step-by-step process to the building of this microalgae shaker. | King's College London | https://app.labstep.com/sharelink/221d4460-8591-4ab5-ac0c-70b54c93532a | 1 | 2020 | Jakub Nedbal 2020.

RNA-Stable Isotope Probing Resource Report Resource Website |
Roey Angel, Eva Petrova, Ana Lara | DOI:10.17504/protocols.io.bjaakiae | SoWa RI Anaerobic and Molecular Microbiology (public) | The following protocol describes how to perform an RNA-Stable Isotope Probing experiment. The scope of this protocol only covers the parts involving separating labelled RNA from unlabelled RNA using ultracentrifugation in a caesium trifluoroacetate density gradient and downstream quantification to evaluate whether the labelling and separation of the RNA were successful. Total RNA should be extracted from an environmental sample or an enrichment culture that was incubated with an isotopically-labelled substrate. Labelling can be of the carbon, oxygen or nitrogen in the RNA (or any combination of the 3). For environmental samples, we recommend extracting RNA using our protocol Total Nucleic Acids Extraction from Soil and purifying it using the Purification of RNA from Crude NA Extract protocol. This protocol is based on the following papers: Whiteley et al. (2007); Dumont et al. (2011); Angel and Conrad (2013). For a comprehensive discussion on how to design a SIP experiment and how to analyse the resulting data, we recommend referring to the recent book on the subject: Stable Isotope Probing: Methods and Protocols, especially chapters: 1-3 and 9-18. | Soil and Water Research Infrastructure, Soil and Water Research Infrastructure, Soil and Water Research Infrastructure | 2 | 2020 | Roey Angel, Eva Petrova, Ana Lara 2020.
