Environ Microbiome. ] The BGI sequencing platform is being increasingly used in clinical pathogen mNGS detection due to its low cost, short sequencing time and other advantages. ] bacteria,[ An official website of the United States government. The Kraken 2 algorithm optimizes the storage index of kmers, which reduces the memory required and improves the speed by reducing memory usage by 85%. Tissue samples account for one of the most common types of clinical samples as they allow for the detection of various infections, including lung, brain, skin, and soft tissue. 65 BMC Genomics 9: 312. ], A large proportion of the samples are collected from the respiratory tract, where the microbiome is particularly difficult to characterize, with diverse pathogens causing infectious diseases, as well as colonizers. 2 The output of Illumina sequencing is the highest among all NGS, making it suitable for multiplexing hundreds of samples at the same time [32]. Raw sequencing data can be generated using different platforms, for which the first in silico analysis step involves the separation of data for each sample into independent files per index of the individual sample library. MeSH Wommack, K.E., J. Bhavsar, and J. Ravel. doi:10.1038/nature06810. Applied and Environmental Microbiology 74: 14531463. Mi, B. Lazareva, T. Hatton, A. Narechania, K. Diemer, A. Muruganujan, N.

Publishing on IntechOpen allows authors to earn citations and find new collaborators, meaning more people see your work not only from your own field of study, but from other related fields too. One of the catalysts for this change has been the advent of high-throughput sequencing (aka next-generation sequencing). Lai, Y.D. The ePub format uses eBook readers, which have several "ease of reading" features ] Although sequencing technology has made various strides in the detection of virulence factors and drug resistance genes, there are certain differences between mNGS and WGSbased detection, with challenges persisting in the application of mNGS for practical detection. Kodira, X.Q.H. Generating an ePub file may take a long time, please be patient. A genomewide study on the virulence genes of K. pneumoniae clinical isolates identified 21 new genes in addition to the iroBCD/iucABCD and rmpA/A2 genes already known to be associated with virulence. Notably, nanopore DNA sequencing is orders of magnitude faster than other strategies for the diagnosis of infectious diseases. Qiao H, Chen L, Yang J, Zhi W, Chen R, Lu T, Tan H, Sheng Z. 77 Third, the drug resistance mechanism is complex and diverse; the current databases for drug resistance genes and virulence genes require improvement, and there are inconsistencies in the reports of genotypes and phenotypes of pathogens. The human reference genome (current version: GRCh38.p13, release date 2020.04) consists of chromosomal scaffolds, unplaced scaffolds, and alternate scaffolds, with the latter representing sequences that are divergent from the primary chromosome sequence.

In May 2019, more than 20 units participated in a joint study launched by the National Institutes of Food and Drug Control to evaluate the quality of the metagenome secondgeneration sequencing reagents used for pathogen detection. The bioinformatics analysis process starts with the fastq date, including the removal of lowquality and lowcomplex sequences, host and engineering bacteria sequences, and the identification of pathogens. 133 The features and principles of first-generation sequencing, SGS, and TGS. ] Further, libraries constructed using the Nanopore kits do not require the reverse transcription of RNA into cDNA, as it is possible to directly sequence the single RNA strand. In addition to the aspects mentioned above, it is also important to take note of the following: i) incomplete sequences of rare pathogens or emerging pathogenic strains, ii) biased references toward species, iii) genetically similar pathogens (e.g., contamination of mycobacterial strains), and iv) the presence of normal flora in reagents, which is a common phenomenon that limits specificity. Science 318: 97100. 123 Larger and more complete databases that contain publicly stored sequences, such as the NCBI nucleotide database, are more comprehensive and more accurate than the limited databases, such as FDAArgos or RVDB, though the larger databases may contain more errors. Although beadbeading is more generally applicable, the cell wall cracking efficiency can be highly variable depending on equipment, buffer, and the cell type. The data output of a single flow cell in the platform is 1025Gb, with the sequencing time ranges from 0 to 48 h, and read lengths of 800kbcan be achieved, through the error rate can be as high as 540%.

The revolution in sequencing technologies High throughput technologies promote the accumulation of enormous volumes of genomic and metagenomics data. 140 Processing the samples before library construction can reduce the host genome proportion, significantly increase the sequence coverage of pathogens in the samples, and improve the detection sensitivity. ], The pipeline for the evaluation and analysis of microbe testing can include DisCVR for virus identification and realtime fluorescence quantitative PCR (RTPCR) analysis as a reference. Various pathogenic microbes can infect the CNS, presenting as meningitis, encephalitis, and abscess, which are often lifethreatening; however, routine microbiological tests are often insufficient to detect all neuroinvasive pathogens, especially for rare pathogens. For secondgeneration sequencing to detect viruses, samples can be centrifuged at a low speed of 6000 g for 10 min, and the supernatant filtered using a 0.80 m filter to remove eukaryotic and bacterial cells without affecting the extraction of RNA viruses. The AB SOLiD sequencing approach differs from the other two next-generation sequencing technologies, Illumina, and 454 pyrosequencing. Pinard, R., A. de Winter, G.J. In addition, the Ion Torrent approach is characterized by its high speed and low cost compared with pyrosequencing and Illumina [35]. 76 Untargeted NGS had a high NPV compared with conventional methods. ] Although tissue samples often have high human cell background content, their sequences can be eliminated from analysis by using an appropriate dehosting process to improve the sensitivity of overall detection. Introduction The development of next-generation sequencing (NGS) techniques provides high-throughput sequence analysis with the ability to simultaneously and independently sequence billions of DNA molecules. 189 Plasma samples from 40 returning travelers presenting with a fever of 38C, A single center, proofofprinciple study. During sequencing, repetitive cycles of DNA polymerase and one labeled nucleotide are flowed, resulting in DNA template extension which depends on the flow of nucleotides. 25 mNGS detection of cfDNA can be applied in monitoring organ transplant rejection via genome transplant dynamics, and may have the potential to replace invasive techniques, such as lung and endomyocardial biopsies as the symptoms of infection and rejection are often difficult to discriminate. Therefore, treatment primarily depends on empirically provided therapy. 118 HighThroughput Metagenomics for Identification of Pathogens in the Clinical Settings, Received 2020 Aug 31; Revised 2020 Oct 24. ] (Table , 2001. ] However, negative tests must be interpreted with caution owing to the higher risk of falsenegative results. The advancements in the field of metagenomics are amazing, and it became easier, cheaper, and faster. , 181 , 80 99 ] A combined approach that incorporates annotated sequences from multiple databases may encourage greater confidence in the sensitivity and specificity of microorganism identification. , Illumina, formerly known as Solexa, has been introduced commercially in 2007. mNGS can be used as a supplement of current routine tests. In fact, due to its low cost per base and high yield, Illumina becomes the most widely used and popular NGS platform.

Currently, all dehosting DNA schemes have certain inherent limitations, and a combination of several schemes may be considered in the future to achieve maximum host DNA removal. Wheeler, D.A., M. Srinivasan, M. Egholm, Y. Shen, L. Chen, A. McGuire, W. He, Y.J. Nevertheless, during the novel coronavirus pandemic, the PacBio system has been employed numerous times for whole genome sequencing and reassembly of SARSCoV2. [ ]. [ Pathogenic infections require varying treatments, making it imperative that their detection is accurate, direct, and verifiable. Therefore, although these samples can be preserved for an extended period of time and are important for the detection of infectious diseases, they can be difficult to process and analyze effectively. The application of mNGS in the detection of clinical pathogens remains in the early stage, with no mNGS workflows or methods approved by the Food and Drug Administration or National Medical Products Administration for the diagnosis of infectious diseases. Auch, J. Qi, and S.C. Schuster. 168 8) Report: the possible pathogens were screened out according to the analysis results. Deng, V. Di Francesco, P. Dunn, K. Eilbeck, C. Evangelista, A.E. , Metagenomic data can be used to profile high-importance genes within microbiomes. The optimal threshold of 850 kmers for DisCVR and 150 reads for CLARK and Kraken is appropriate.

W., Weinstock G., The Professional Practice Committee and Committee on Laboratory Practices of the American Society for Microbiology ] However, at present, it is generally recognized that mNGS will not likely universally replace traditional microbiology techniques in the short term for the following reasons: i) some traditional detection methods are highly sensitive and specific with rapid turnaround times, such as CSF CrAg, rapid and specific PCR methods; ii) indirect approaches such as serological tests will continue to play a key part in the diagnostic workup for infections, especially for the emerging infectious diseases;[ Reproducibility of read numbers in high-throughput sequencing analysis of nematode community composition and structure. For taxonomic classification, alignments are performed relative to reference databases regardless of the algorithm used. UNITED KINGDOM, Ahmed Shuikan, Sulaiman Ali Alharbi, Dalal Hussien M. Alkhalifah and Wael N. Hozzein, Metagenomics - Basics, Methods and Applications. Chemistry & Biology 5: R245R249. 153 Smith, M. Yandell, C.A. 4 Next, damage repair and end repair of the DNA template is performed to enable its use in direct sequencing and to avoid negative effects on read length. It is easy now to study and identify organisms directly from their habitats without prior preparations. [ The true dehosting efficiency remains to be confirmed by additional experimental data. 55 163 specimens (CSF, blood, and throat swabs) from 105 patients suspected with viral encephalitis/meningitis or respiratory infection from May 2017 to June 2019. 134 [ Blow, M.J., T. Zhang, T. Woyke, C.F. In the clinical field, NGS was used to inform the real-time incidence and prevention response to human parainfluenza 3 virus infections [7] and for cerebrospinal fluid diagnostics [8]. Begley, and J.M. Mycokeys 39 , 29-40 (2018). [ ] Based on relative abundance, viruses in the blood samples can be filtered for detection, and in clinical samples, thresholds of 1% for relative abundance and 0.01% for total reads classified have been applied. , R. L. M., 2017. 85 Finally, the light emission from PTP is recorded by a CCD camera and is translated to nucleotide sequences [29]. mNGS showed a positive percent agreement of 86.30% in a variety of tissues, higher than culture (45.21%) and other conventional methods (57.53%). doi:10.1371/journal.pcbi.0010024. 2008. (Table Zhejiang 28 Surprisingly, sequencing can be carried out in the field by utilizing a pocket-size portable sequencer. Of these, 82% were > 199 bp in length. 113 Small Methods. 220 Roth, G.J. Sarkis, M.B. Moreover, it remains to be determined how to: i) minimize the influence of human host background and extraneous sources of nucleic acids; ii) differentiate colonization from infection; iii) improve the detection efficiency of intracellular microorganisms; iv) generate more reasonable standardization of the methods, data storage, protection, analysis, and interpretation. Tripp, and J.P. Affourtit. Currently, the most widely employed secondgeneration sequencer in clinical settings is manufactured by Illumina, followed by Beijing Genomics Institute (BGI). ] mNGS is considered to have the potential of being used as an allinone diagnostic test for FUO patients, helping differentiate infections and noninfections, identify causative agents, and discover novel or emerging pathogens. The Trimmomatica or Fastp tools are commonly used for the removal of lowquality reads, adaptors, and short reads. We set up four artificial metagenomic samples involving 41 diverse reference nematodes in known abundances. Chang, H.W. HHS Vulnerability Disclosure, Help [ FOIA 5) Library preparation: library construction method is selected according to the sequencing platform and purpose. Amplified products involved two rapidly evolving ~400-bp sections coding for the small and large subunit of rRNA. , Li, R.J. Mural, G.G. This site needs JavaScript to work properly. , In the BGI prescribed method, the DNA overhangs are filled in to form bluntended molecules, and a sequence of connectors is added to the two DNA fragments ends to connect them, forming a ring structure. PubMedGoogle Scholar. , Incorporation of nucleotides into the growing chain results in the dissociation of the labeling groups, which reduces steric hindrance and helps maintain the continuous synthesis of DNA chains, prolonging the sequence read length. 24 Periprosthetic tissue can be used as an alternative to synovial fluid and sonication fluid. (3) Loaded beads are transferred into the sequencing plate with millions of wells. 2022 Jan 12;11:798367. doi: 10.3389/fcimb.2021.798367. First, samples generally expend a large amount of sequencing output consuming human DNA sequences, leading to insufficient coverage for the detection of pathogen DNA and limiting the comprehensive analysis of drug resistance genes. 204 For example, in 2017, Chinese scientists detected Pseudorabies Virus in vitreous humor for the first time using NGS technology, while Sanger sequencing was used to further verify their findings. Analyzing the human microbiome: a "how to" guide for physicians. The following section will describe the mNGS detection process for samples suitable for different infection systems (Figure 117 , [ , [ It is therefore becoming more widely used to study whole communities of prokaryotes in many niches. [ Upper and lower respiratory tract infections are among the most common illnesses leading to medical consultation, and are associated with significant mortality. Packard, F.Q. Sequencing technology is becoming increasingly available in clinic. The average genome size of viruses is smaller than 50kb. BMC Bioinformatics 9: 386. mNGS has higher sensitivity for pathogen identification. Instead of utilizing DNA polymerase, short nucleotides marked by DNA ligase known as interrogation probes are used. 2017 Nov 10;261:10-23. doi: 10.1016/j.jbiotec.2017.08.012. The current approach is more beneficial than single-cell nucleotide data and RNA sequencing approaches. Bethesda, MD 20894, Web Policies Cell 134: 708713. 130 volume33,pages 944952 (2010)Cite this article. The emergence of several next-generation sequencing (NGS) strategies enriched the metagenomics. Further, the run time required for secondgeneration sequencing is long with most sequencers requiring more than 12 h, hence, the sequencing data cannot be obtained in realtime. For intracellular bacteria, such as MTB and Legionella, the threshold is relatively low, and credible data can be obtained with a threshold of 1 RPM. ] mNGS can overcome the limitations of traditional diagnostic tests, enabling a hypothesisfree, cultureindependent, and universal pathogen detection platform, with which clinical specimens can be directly used for microbe identification of bacteria, viruses, fungi, or parasites, while also assisting in the identification of novel organisms. Proceedings of the National Academy of Sciences of the United States of America 105: 38053810. [ Jackson. 57 (1) Beads coated with either streptavidin or complementary oligonucleotides complementary to adapter sequences attached to the ends of the fragment to be sequenced. MeSH 228 The ePub format is best viewed in the iBooks reader. For more efficient removal of the host sequences, the human mRNA reference sequence of human can be added to the reference genome simultaneously. In general, higher coverage rate, relative abundance, and SMRN are typically reliable with true infections, whereas lower indices are somewhat discredited for infections or are considered to be more likely associated with the presence of commensal/colonizer/contaminant microorganisms of unknown clinical significance. Brady, J. Clardy, and R.M.
