Paper-Based Airborne Bacteria Collection and DNA Extraction Kit

Paper-Based Airborne Bacteria Collection and DNA Extraction Kit
The crucial danger from airborne infectious illnesses, bio-weapons, and dangerous micro organism is presently the very best it has ever been in human historical past. The requirement for monitoring airborne pathogens has progressively elevated to defend towards bioterrorism or forestall pandemics, particularly through easy and low-cost platforms which might be utilized in resource-limited settings.
Right here, we developed a paper-based airborne micro organism assortment and DNA extraction equipment appropriate for easy software with minimal devices. Airborne pattern assortment and DNA extraction for PCR evaluation had been built-in within the paper equipment.
We created an easy-to-use paper-based air monitoring system utilizing 3D printing know-how mixed with an air pump. The operation time of your entire course of, comprising air sampling, bacterial cell lysis, purification and focus of DNA, and elution of the DNA analyte, was inside 20 min.
All of the investigations and optimum settings had been examined in a custom-designed closed cupboard system. Within the fabricated cupboard system, the paper equipment operated successfully at a temperature of 25-35 °C and 30-70% relative humidity for air containing 10-106 CFU Staphylococcus aureus. This paper equipment might be utilized for easy, speedy, and cost-effective airborne pathogen monitoring.

New Estimation of Antibiotic Resistance Genes in Sediment Alongside the Haihe River and Bohai Bay in China: A Comparability Between Single and Successive DNA Extraction Strategies

Sediment is considered an important reservoir for antibiotic resistance genes (ARGs). Typically, research describing and evaluating ARGs and their potential hosts in sediment are primarily based on single DNA extractions.
To this point, nonetheless, no examine has been performed to evaluate the affect of DNA extraction effectivity on ARGs in sediment. To find out whether or not the abundance of ARGs is underestimated, we carried out 5 successive extraction cycles with a broadly used industrial equipment in 10 sediment samples collected from the Haihe River and Bohai Bay.
Our outcomes confirmed that gathered DNA yields after 5 extractions had been 1.8-3.1 instances increased than that by single DNA extractions. Excessive-throughput sequencing confirmed that inadequate DNA extraction might generate PCR bias and skew neighborhood construction characterization in sediment.
The relative abundances of some pathogenic micro organism, akin to Enterobacteriales, Lactobacillales, and Streptomycetales, had been considerably totally different between single and successive DNA extraction samples. As well as, real-time fluorescent quantitative PCR (qPCR) confirmed that ARGs, intIextraction cycles.
Among the many measured ARGs, sulfonamide resistance genes and multidrug resistance genes had been dominant subtypes within the examine area. Nonetheless, totally different subtypes of ARGs didn’t reply equally to the extra extraction cycles; some continued to have linear development traits, and a few tended to degree off.
Moreover, extra correlations between ARGs and bacterial communities had been noticed within the successive DNA extraction samples than within the single DNA extraction samples. It’s advised that 3-Four extra extraction cycles are required in future research when extracting DNA from sediment samples.
Taken collectively, our outcomes spotlight that performing successive DNA extractions on sediment samples optimizes the extractable DNA yield and may result in a greater image of the abundance of ARGs and their potential hosts in sediments.

A comparability of various DNA extraction strategies and molecular methods for the detection and identification of foodborne pathogens

Foodborne infections proceed to plague Europe. Meals security monitoring is in disaster as the present methods for detecting pathogens don’t sustain with the worldwide rising of meals manufacturing and consumption. Thus, the event of revolutionary methods for detecting and figuring out pathogenic micro organism has develop into crucial.
The purpose of the current examine was firstly to develop an revolutionary easy and low price methodology of extracting bacterial DNA from contaminated meals and water samples with Salmonella enteric(a) subsp. enteric(a) serovar Typhimurium and Listeria monocytogenes and its comparability with two industrial DNA extraction kits (Qiagen, Macherey-Nagel).
Lastly, pathogens’ detection utilizing two molecular methods (PCR-electrophoresis, LAMP), with the intention to consider one of the best mixture of DNA extraction and identification primarily based on their sensitivity, price, rapidity and ease.
Contemplating the above standards, amongst them, greatest was proved an in-house bacterial DNA extraction methodology, primarily based on the chloroform-isoamyl alcohol protocol, with sure modifications.
This system confirmed statistically comparable outcomes by way of sensitivity, in comparison with the industrial kits, whereas on the similar time maintained excessive rapidity and far decrease price.
Lastly, between the molecular methods, LAMP was discovered extra promising contemplating its simplicity, excessive rapidity and sensitivity. Conclusively, the in-house DNA extraction methodology together with the LAMP approach, was confirmed to be one of the best among the many offered mixtures.

A Easy, Price-Efficient, and Automation-Pleasant Direct PCR Method for Bacterial Group Evaluation

Bacterial communities in water, soil, and people play a necessary position in environmental ecology and human well being. PCR-based amplicon evaluation, akin to 16S rRNA sequencing, is a basic device for quantifying and finding out microbial composition, dynamics, and interactions.
Nevertheless, given the complexity of microbial communities, a considerable variety of samples turns into crucial for analyses that parse the elements that decide microbial composition.
A typical bottleneck in performing these sorts of experiments is genomic DNA (gDNAextraction, which is time-consuming, costly, and infrequently biased primarily based on the kinds of species current. Direct PCR methodology is a probably less complicated and extra correct various to gDNA extraction strategies that don’t require the intervening purification step.
On this examine, we evaluated three variations of direct PCR strategies utilizing numerous heterogeneous bacterial cultures, together with each Gram-positive and Gram-negative species, ZymoBIOMICS microbial neighborhood requirements, and groundwater.
By evaluating direct PCR strategies with DNeasy Blood and Tissue Kits for microbial isolates and DNeasy PowerSoil Kits for microbial communities, we discovered that a particular variant of the direct PCR methodology reveals an general effectivity corresponding to that of the traditional DNeasy PowerSoil protocol within the circumstances we examined.
We additionally discovered that the tactic confirmed increased effectivity for extracting gDNA from the Gram-negative strains in comparison with DNeasy Blood and Tissue protocol. This direct PCR methodology is 1,600 instances inexpensive ($0.34 for 96 samples) and 10 instances less complicated (15 min hands-on time for 96 samples) than the DNeasy PowerSoil protocol.
The direct PCR methodology will also be totally automated and is suitable with small-volume samples, thereby allowing scaling of samples and replicates wanted to help high-throughput large-scale bacterial neighborhood evaluation.
Understanding bacterial interactions and meeting in complicated microbial communities utilizing 16S rRNA sequencing usually requires a big experimental load.
Nevertheless, the present DNA extraction strategies, together with cell disruption and genomic DNA purification, are usually biased, expensive, time-consuming, labor-intensive, and never amenable to miniaturization by droplets or 1,536-well plates as a result of vital DNA loss throughout the purification step for tiny-volume and low-cell-density samples.
A direct PCR methodology might probably clear up these issues. On this examine, we developed a direct PCR methodology which reveals comparable effectivity because the broadly used methodology, the DNeasy PowerSoil protocol, whereas being 1,600 instances inexpensive and 10 instances sooner to execute.
