The next set was on saliva samples, directly on saliva samples

Mu Free Donor (MFDpir) or B2155, which contain integrated rp4-based transfer machinery

LOD was defined as <x>bi + ksbi, where <x>bi equals the mean of the no-template controls, sbi is s.d. of no-template controls and k = 2.479 (99% confidence interval)

combining:5.5 μL probe; 19.8 μL forward primer; 19.8 μL reverse primer; 64.9 μL dH2O(volumes can be scaled up). This 20× master mix can be frozen and used in subsequent experiments

Bacteria-specific primer pairs used were 27F (AGAGTTTGATCMTGGCTCAG) and 1492R (TACGGYTACCTTGTTACGACTT) [26] and 63F (CAGGCCTAACACATGCAAGTC) and M1387R (GGGCGGWGTGTACAAGRC)

Nutrient Agar is a general purpose, nutrient medium used for the cultivation of microbes supporting growth of a wide range of non-fastidious organisms.

Different nutrient media were used for selective cultivation of bacteria: kanamycin esculin azide (KAA, Merck Eurolab, Darmstadt, Germany) for enterococci, and Chromocult® agar (Merck) as a selective agent for Enterobacteriaceae. For the heterotrophic plate count the bacterial dilutions were plated on R2A agar

R-2A Agar is formulated as per Reasoner and Geldreich (5). Stressed or injured organismsduring water treatment are unable to grow on high nutrient media, since the faster growing organisms outgrow the former(2). Therefore the use of a low nutrient medium like R-2A Agar incubated for longer incubation periods allows these stressedorganisms to grow well.

MacConkey agar is selective for Gram-negative organisms and helps to differentiate lactose fermenting gram-negative rods from non-lactose fermenting gram-negative rods. It is primarily used for the detection and isolation of members of family enterobacteriaceae and Pseudomonas spp.

genetic devices have been designed for suppressing leaky basal expression levels through the engineering of super‐repressors (Ruegg et al, 2018), exploitation of antisense RNAs (O'Connor & Timmis, 1987), or physical decoupling of regulatory elements along with conditional proteolysis

The neighbour‐joining tree was prepared with the R package {Ape} (Paradis, Claude, & Strimmer, 2004) and visualized using the R package {ggtree} (Yu, Smith, Zhu, Guan, & Lam, 2017).

except for E. coli (which requires Eiken agar

enabling precise control over agronomically-relevant outputs such as flowering time, stress response, or the biosynthesis of added value metabolites.

Despite the potency, curcumin has not yet been approved as a therapeutic antiviral agent.

In order to reduce false-negative results related to strain variation, TaqMan oligonucleotides were designed in a very conserved region of the M gene.

The relationship between this diversity and the invasion of antibiotic resistance was investigated using a dilution-to-extinction approach coupled with high-capacity quantitative PCR

our previous studydemonstrated that the manure-borne ARGs proliferated moreeasily ing-irradiated soil than natural soil, indicating thatindigenous soil microorganisms could prevent the dissemina-tion of ARGs from manure to soil

Eachflask received 1.2 g of pig manure as the sourceof ARGs

Four concentrations of the soilsuspension were used as inocula to create a diversity gradient

showing the relationships of ARG abundance with OTU richness, diversity andevenness.

Bars represent averages of four replicates

Little is known, however, about the barriers that microbial diversity provides against microbial invasion

If that is too limited, you need to use a nested or split workflow

Designing Probes for a ddPCR Assay

ultimate conclusion of the thesis reads “the unknown virus lead to severe pneumonia could be: The SARS-like-CoV from the Chinese rufous horseshoe bat.

However, we recommend that other qPCR targets, including the RdRp or envelope (E) genes are used for the routine detection of 2019-nCoV

we measured the relative abundance of dead cells in cultures of the resistant strain grown at sub-MICR concentrations of streptomycin

LoD = LoB + 1.645(SD low concentration sample)

There is a simple mathematical relationship between the fraction of droplets that are unoccupied (black bar) and the concentration of target molecules.

Some droplets are lost in transfer steps and others are eliminated by the stringent metrics applied by QuantaSoft Software as the droplets pass through the Droplet Reader, resulting ultimately in data from 12,000–16,000 droplets being used in subsequent concentration calculations

Mathematical Analysis of Copy Number Variation in a DNA Sample Using Digital PCR on a Nanofluidic Device.

An estimate of par-titioning error can be found based on the analysis of Dube et al.,39 which models the partitioning as a binomial process.

Digital assays have two sources of error: subsampling error and partitioning error

Partitioning the sample into small containers results in a statistical distribu-tion of targets

because it measures indi-vidual molecules rather than an ensemble concentration

purifying the target of interest from interfering compounds.

Subsampling error sets the lower detection limit at low concentrations and is independent of the instrument, while partitioning error domi-nates at high concentrations and may depend on the sampling and partitioning instrument

The average number of droplets read for each ddPCR was 13,825 with a standard deviation of 1,892 droplets

NTCs showed a low-level background signal of approximately three positive droplets per NTC assay, which could possibly be attributed to low-level template contamination during the preparation of the reaction mixture

simple calibration procedure generated an instrument-specific color compensation matrix that was subsequently stored on the droplet reader and automatically applied to data to eliminate cross talk between FAM and VIC labeled probes.

Poisson distribution can be used in place of other standard curves to determine template concentration, which means that data can be reliably obtained from the same samples across multiple instruments and laboratories.

minimizing the need for local variables

the lowest copy number sample points impacted faster and sronger, then you just need to stabilize by adding a neutral nucleic acid background in your standard curve. I usually use water containig 10ng/microl yeast tRNA to perform serial dilutions. This will first create a reaction background similar to your RTQPCR reaction, but also stabilize your DNA copies; I can freeze and thaw (min 20C) more than 50 times the same standard curve sample without any loss in Cts, from 10E6 to 10E2 copies. When I tested the same standard curve but diluted in water only, then the 10E2 started to be slightly affected after one freeze and thaw and then crashed further; then higher copy numbers samples were also affected after 2 to 3 freeze and thaw.

t is important that the threshold is set at a fixed level for all samples that are to be compared

If you use an inter-plate calibrator for each different GOI and reference gene, then you would have the rationale to use a different threshold for each target and ref. gene on each different plate.

In most programming languages, you can only access the values of a function’s arguments. In R, you can also access the code used to compute them. This makes it possible to evaluate code in non-standard ways: to use what is known as non-standard evaluation

a single TaqMan Fast Virus 1-Step Master Mix protocol has been developed to assay both types of nucleic acid, so you can perform RNA and DNA virus queries next to each other on the same plate using the same handling steps

The present study identifies the best assay for norovirus GI and GII to amplify norovirus genomes efficiently.

A known copy (104/reaction) of Oncorhynchus keta (O. keta) was added in the DNAse and RNAse free water and the Cq value obtained acted as a reference point. If the Cq value of a wastewater sample increases compared to the reference Cq value, the sample is considered to have PCR inhibitors.

adjusted for the time lag, the virus RNA concentrations were highly correlated with the COVID-19 epidemiological curve (R2=0.99) and local hospital admissions (R2=0.99)

The Rn value, or normalized reporter value, is the fluorescent signal from SYBR Green normalized to (divided by) the signal of the passive reference dye for a given reaction. The delta Rn value is the Rn value of an experimental reaction minus the Rn value of the baseline signal generated by the instrument. This parameter reliably calculates the magnitude of the specific signal generated from a given set of PCR conditions

But if we do not lift the lockdown with immediate effect, we shall be confronted with mass ruin and a breakdown of all our structures — social, economic and emotional.

Rosario et al. recovered between 63 and 77% of spiked PMMoV in treated wastewater using centrifugal ultrafiltration

Although unnecessary for simple singleplex amplifications, spectral calibration is critical for multiplexed assays so that overlapping fluorescent signals can be resolved from one another.

to concentrate the viruses, the 1‐l aliquot was acidified with 1 mol l−1 acetic acid to pH ~3·0 and then viruses were filtered onto a 47‐mm, 0·45‐μm HA negatively charged nitrocellulose filter

PMMoV concentrations vary over space and time, 106 to 1010 gene copies per liter of domestic wastewater are consistently detected

By far, the most abundant RNA virus identified in the feces of healthy individuals was PMMoV [6], which has also been readily identified in untreated wastewater from numerous locations

may be due to bacterial extracellular enzyme activity and protozoan or metazoan predation

Samples were spiked to achieve final virus concentrations of 5 × 104 PFU mL–1 for MHV, and 6—8 × 105 PFU mL–1 for ϕ6, MS2, and T3—these were low enough to be feasible concentrations present in wastewater (<106 PFU mL–1)

The spiked samples were stirred and then incubated at 4 °C; this temperature is at the low-end of mean municipal wastewater temperatures in the U.S.

Likewise, methods to concentrate and recover nonenveloped enteric viruses from wastewater and other environmental matrices may not be suitable for enveloped viruses.

The period from the beginning of antibiotic treatment (50 to 60 years ago) to the emergence of bacteria expressing effective resistance mechanisms is too short to explain the development of resistance factors from other proteins by spontaneous mutation

plasmid fitness benefits in multiple phylotypes

To persist, plasmids lacking stringent post-segregational killing systems thus depend on one or both of two mechanisms: fitness cost amelioration and horizontal transfer

The harsh environmental conditions found on leaf surface require high metabolic performances of the bacteria in order to survive.

Remove secreted beta-lactamase from the starter cultures. This can be done by pelleting and re-suspending the starter culture in fresh, antibiotic-free medium before innoculating the main culture.

These and other breakthroughs promoted a feeling of optimism that, with the tools of quantum mechanics, the secrets of life could finally be laid bare.

It only takes a few changes ("exchange of a relatively small sequence segment") between two coronaviruses to result in a third coronavirus that can infect other animals ("host-switching")

The odds of this happening are pretty good!

it is equally possible that the virus originated somewhere else entirely

While Mr. Fu here seems to believe the virus originated from the market, we know from the Lancet study that it is unlikely

Because 34% of cases did not have exposure to the market yet were exposed to the virus, it is highly unlikely the market is the origin point of SARS-CoV-2

meaning that the first patient at the market was not responsible for spreading the virus to other cases

Research on enveloped virus presence and fate in water is hindered by the lack of proven detection methods. Detecting and quantifying viruses in environmental samples requires first concentrating the viruses in the sample into a smaller volume to improve detection limits

virus-loaded filters were rinsed with an acidic solution to eliminate remaining cations before elution with NaOH or other alkaline buffers

The 1MDS-method and the HA-method did not provide as high recovery yields of the virions as the Mg-method.

a defined quantity of a nonhuman control virus (seal herpes virus [SHV], kindly provided by H. G. M. Niesters, University of Rotterdam, The Netherlands) was spiked into each sample prior to DNA and RNA extraction. Since constant DNA quantities of the control virus are coextracted even when RNA isolation kits are used (H. G. M. Niesters, personal communication; our own unpublished observations), the virus can also serve as a control in RNA virus detection assays.

on the topic of working with sewage to detect viruses, there are new guidelines from the US CDC that require BSL-3 PPE.

wastewater monitoring in Israel, for example, picked up a polio outbreak before any clinical cases appeared at all, according to a 2018 study.

transfer

However, using metabolites as reporters requires more precise control than what is necessary for most metabolic engineering applications, since small amounts of enzyme can produce visible amounts of pigment and overproduction of certain metabolites can be toxic to the cell.

In this paper, we designed a system that could fully repress lycopene production in the absence of an inducer and produce visible lycopene within two hours of induction. We engineered Lac, Ara, and T7 systems to be up to 10 times more repressible, but these improved systems could still not fully repress lycopene. Translational modifications proved much more effective in controlling lycopene. By decreasing the strength of the ribosomal binding sites on the crtEBI genes, we enabled full repression of lycopene

More than a dozen research groups worldwide have started analysing wastewater for the new coronavirus as a way to estimate the total number of infections in a community

de Roda Husman’s group detected traces of SARS-CoV-2 in wastewater at Schiphol Airport in Tilburg only four days after the Netherlands confirmed its first case of COVID-19 using clinical testing

ultrafiltration method resulted in mean recoveries (±SD) of 25.1% (±3.6%) and 18.2% (±9.5%) for the enveloped MHV and ϕ6, respectively

The SARS outbreak was fueled by bioaerosol generation during the collection and transport of sewage that allowed for distant disease transmission (Roy and Milton, 2004; Yu et al., 2014)

wastewater treatment disease transmission studies from that time did not usually consider respiratory pathogens.

To collect, process, and act on information, cells must be able to accurately record signals.

In an attempt to mitigate the problem of DNA from inactive cells influencing microbial analysis, molecular techniques have been developed to remove or bind the extracellular DNA prior to cell lysis

It is unlikely that colistin pressure in the environment and animals, especially in water environment, may be the only cause of the existence of such an ubiquitous presence of these enzymes that could be mobilized within bacteria.

Our innovative approach, i.e. massive genome analysis, appears to be a powerful tool and a new concept that opens a new field of big data analysis and research
