Need Help Identifying 2 Unknown Viruses


S. et al. De Bolle L, Naesens L, De Clercq E. doi: 10.1002/rmv.524. [PubMed]44. Source

We utilized a barcoding strategy to simultaneously deep sequence multiple serum specimens, generating on average over 1 million reads per sample. Y.L. Nevertheless, the sensitivity of such techniques has not been evaluated with regard to the detection of low levels of viruses and/or viruses that are genetically distant from known viruses, which is Y.L., H.W.

We have considered that a fair comparison between the two techniques corresponded to a number of reads corresponding to around 1/20 of a run; that is, a range of 2 × Identification of herpesvirus-like DNA sequences in AIDS-associated Kaposi's sarcoma. et al.

Science 300, 1394–1399 (2003).ISICASPubMedArticleDawood, F. We found that whereas Omniscript RT was more efficient at amplifying 200 bp cDNA species, SuperScript II RT was more efficient at amplifying 1.4 Kb fragments (Figure ​(Figure5A).5A). Proc. Med.

Metagenomic approaches to pathogen detection, such as viral microarrays and deep sequencing, are promising tools to address emerging and non-diagnosable disease challenges. Virus Identification Methods doi: 10.1073/pnas.242579699. [PMC free article] [PubMed]15. Virochip analysis produced putative viral hits in 10/123 (8%) of the previously negative samples, whereas deep sequencing revealed virus or virus-like sequences in 45/123 (37%). We also inoculated human plasma with Respiratory Syncytial Virus B and were able to amplify and identify genomic RNA using the 5'-VVVVVVVVAA-3' primers (data not shown).

Urisman A, Molinaro RJ, Fischer N, Plummer SJ, Casey G, et al. We postulated that "locking" the 3' end of the primers with 2 adenosines and not incorporating any thymidines into the upstream 5' portion of the primers would prevent primer-dimer amplification (i.e., L., Peret, T....Zaki, S. For each genus, coverage map(s) for the reference sequence(s) were then generated.Phylogenetic analysis and multiple k-mer based de novo assemblyThe construction of a phylogenetic tree allows us to visualize the underlying

Human Herpesvirus 6 Latently Infects Early Bone Marrow Progenitors In Vivo. Thus, Illumina sequencing with a depth of ∼7 millions reads per sample allowed identification of viruses at a level close to dedicated and optimized quantitative (RT-)PCRs. Quantification was performed using a standard dilution curve using a plasmid encompassing the nucleotide target, with limits of quantification and detection for both primer sets of >20 and 0.5 copies/μl, respectively.

Primary infection in adolescents or adults can manifest as infectious mononucleosis, and chronic infection is associated with various malignancies later in life. N Engl J Med. 1994;331:432–438. We were surprised that the cloned DNA from Coxsackievirus A7 aligned with the known sequence for Coxsackievirus A16 until we learned that the Coxsackievirus A7 strain had not been fully sequenced This virus is a dsDNA virus.
