Abstract
Multiple-type human papillomaviruses (HPV) infection presents a greater risk for persistence in asymptomatic individuals and may accelerate cancer development. To extend the scope of HPV types defined by probe-based assays, multiplexing deep sequencing of HPV L1, coupled with an HPV-QUEST genotyping server and a bioinformatic pipeline, was established and applied to survey the diversity of HPV genotypes among a subset of healthy men from the HPV in Men (HIM) Multinational Study. Twenty-one HPV genotypes (12 high-risk and 9 low-risk) were detected in the genital area from 18 asymptomatic individuals. A single HPV type, either HPV16, HPV6b or HPV83, was detected in 7 individuals, while coinfection by 2 to 5 high-risk and/or low-risk genotypes was identified in the other 11 participants. In two individuals studied for over one year, HPV16 persisted, while fluctuations of coinfecting genotypes occurred. HPV L1 regions were generally identical between query and reference sequences, although nonsynonymous and synonymous nucleotide polymorphisms of HPV16, 18, 31, 35h, 59, 70, 73, cand85, 6b, 62, 81, 83, cand89 or JEB2 L1 genotypes, mostly unidentified by linear array, were evident. Deep sequencing coupled with HPV-QUEST provides efficient and unambiguous classification of HPV genotypes in multiple-type HPV infection in host ecosystems.

<abstract><p>Multiple-type human papillomaviruses (HPV) infection presents a greater risk for persistence in asymptomatic individuals and may accelerate cancer development. To extend the scope of HPV types defined by probe-based assays, multiplexing deep sequencing of HPV L1, coupled with an HPV-QUEST genotyping server and a bioinformatic pipeline, was established and applied to survey the diversity of HPV genotypes among a subset of healthy men from the HPV in Men (HIM) Multinational Study. Twenty-one HPV genotypes (12 high-risk and 9 low-risk) were detected in the genital area from 18 asymptomatic individuals. A single HPV type, either HPV16, HPV6b or HPV83, was detected in 7 individuals, while coinfection by 2 to 5 high-risk and/or low-risk genotypes was identified in the other 11 participants. In two individuals studied for over one year, HPV16 persisted, while fluctuations of coinfecting genotypes occurred. HPV L1 regions were generally identical between query and reference sequences, although nonsynonymous and synonymous nucleotide polymorphisms of HPV16, 18, 31, 35h, 59, 70, 73, cand85, 6b, 62, 81, 83, cand89 or JEB2 L1 genotypes, mostly unidentified by linear array, were evident. Deep sequencing coupled with HPV-QUEST provides efficient and unambiguous classification of HPV genotypes in multiple-type HPV infection in host ecosystems.</p>

<p>Human papillomaviruses (HPV) are globally ubiquitous DNA viruses found in mucosal and cutaneous anatomical sites and comprised by more than a hundred genotypes. Low-risk HPV genotypes are associated with genital warts, while high-risk HPV genotypes, in particular HPV16, cause a number of cancers in men and women [<xref rid="B1-viruses-08-00028" ref-type="bibr">1</xref>

]. Consequently, identifying infection as multiple HPV types prior to development of symptoms has explicit clinical value. </p>
<p>Studies of multiple-type HPV infection by conventional probe-based assays are hampered by the limited scope of type-specific probes and/or cross-hybridization by probes for related HPV genomes [<xref rid="B26-viruses-08-00028" ref-type="bibr">26</xref>

]. Direct sequencing based on electropherographs or pyrograms is problematic in accurately defining multiple infections present in one specimen [<xref rid="B31-viruses-08-00028" ref-type="bibr">31</xref>
,<xref rid="B32-viruses-08-00028" ref-type="bibr">32</xref>
]. Next-generation deep sequencing (NGS) technology combines the specificity of sequence data with a capacity to analyze large numbers of samples within a clinical setting. In this study, an HPV-genotyping system was developed by coupling NGS with HPV-QUEST, a web server we developed previously for automated HPV genotyping with a capability of handling up to 10 megabases (Mb) of sequences [<xref rid="B33-viruses-08-00028" ref-type="bibr">33</xref>

<p>The study included 22 samples from 18 men from the United States (n = 15), Brazil (n = 1), or Mexico (n = 2), representing a subset of healthy males from the HPV in Men (HIM) Multinational Study recruited between 2005 and 2008 to examine the HPV prevalence in asymptomatic males [<xref rid="B34-viruses-08-00028" ref-type="bibr">34</xref>

,<xref rid="B37-viruses-08-00028" ref-type="bibr">37</xref>
]. The HIM study was approved by the human-subjects’ committees of the University of South Florida (St. Petersburg, FL, USA), the Ludwig Institute for Cancer Research (São Paulo, Brazil), the Centro de Referẽncia e Tratamento de Doencas Sexualmente Transmissiveis e AIDS, and the National Institute of Public Health of Mexico (Cuernavaca, Mexico). Written consent was obtained from all participants. Participants at study entry were a median (25%–75% quartile range (QR)) age of 22 years (19–31 years), had none to 3 sexual partners within 6 weeks before sampling (<xref ref-type="app" rid="app1-viruses-08-00028">Table S1</xref>
), were HIV-1 negative, and received no HPV vaccines before or during the course of the study. Genital sampling and DNA extraction have been described previously [<xref rid="B35-viruses-08-00028" ref-type="bibr">35</xref>
,<xref rid="B38-viruses-08-00028" ref-type="bibr">38</xref>
]. In brief, saline-wetted Dacron applicators (Digene, Gaithersburg, MD, USA) were used to swab three sites of the external genitalia (glans penis/coronal sulcus, penile shaft, and scrotum), and combined into one sample in 450 µL of specimen transport medium (Digene Corporation, Gaithersburg, MD). DNA was extracted using the Media Kit (Qiagen, Valencia, CA, USA) according to the manufacturer’s instructions, and eluted in a 100- to 120 μL elution buffer. The consistency of sample collection reached 91.4% as tested previously [<xref rid="B38-viruses-08-00028" ref-type="bibr">38</xref>
]. To prevent sample cross-contamination, DNA extraction was carefully performed in a clean and plasmid-free environment. HPV L1 genotyping by linear array (LA) method (Roche Diagnostics, Indianapolis, IN, USA) using PGMY11/09 (PGMY) consensus primers and probes for 37 HPV mucosal types (6, 11, 16, 18, 26, 31, 33, 35, 39, 40, 42, 45, 51–56, 58, 59, 61, 62, 64, 66–72, 73 (MM9), 81, 82 (MM4), 83 (MM7), 84 (MM8), IS39 and CP6108) (Linear Array® HPV Genotyping Test, Roche Molecular Diagnostics, Pleasanton, CA, USA) was performed at the H. Lee Moffitt Cancer Center (HLMCC, Tampa, FL, USA). HPV genotyping by LA was highly reproducible with 83.5% or 93.2% concordance rate for single- or multiple-type detection, respectively [<xref rid="B38-viruses-08-00028" ref-type="bibr">38</xref>
]. The deep sequencing sub-study included samples with HPV L1 genomes identified by the LA method (12 samples including longitudinal samples from 8 participants) or with indeterminate HPV infection (10 samples from 10 participants) reflecting failure either to amplify by PGMY primers or to hybridize by probes in the LA assay. DNA from de-identified samples, provided to the University of Florida (UF) with approval by the Institutional Review Boards at HLMCC and UF, was concentrated by speed vacuum, re-suspended in 5 µL of double distilled water, and used in a single PCR to capture all HPV copies in the sample. The median (QR) input of total DNA was 349 ng (182–995 ng), equivalent to approximately median (QR) of 72,000 cells (31,500–150,000 cells), based on a calculation that 600 ng DNA is equivalent to 100,000 cells [<xref rid="B39-viruses-08-00028" ref-type="bibr">39</xref>

,<xref rid="B42-viruses-08-00028" ref-type="bibr">42</xref>
]. Limited sample DNA precluded direct quantification of total cells or HPV genome copies by quantitative PCR. Deep sequencing coupled with HPV-QUEST [<xref rid="B33-viruses-08-00028" ref-type="bibr">33</xref>
] was applied to a cross-sectional study of 18 individuals, and a longitudinal follow-up of 2 participants with 6 samples obtained at 6-month intervals. DNA extracted from epidermoid cervical cancer cell lines CaSki or C-4 II (ATCC, Manassas, VA, USA) was included in the study for sequence pipeline development and genotyping verification [<xref rid="B43-viruses-08-00028" ref-type="bibr">43</xref>
].</p>

<sec id="sec2dot2-viruses-08-00028"><title>2.2. Generation of HPV L1 Amplicon Libraries and Deep Sequencing</title>
<p>Nested PCR with PGMY [<xref rid="B44-viruses-08-00028" ref-type="bibr">44</xref>
] followed by GP5+/6+ (GP+) [<xref rid="B45-viruses-08-00028" ref-type="bibr">45</xref>
] was used to generate HPV L1 amplicon libraries because PGMY/GP+ has greater sensitivity and broader coverage of HPV genotypes compared to PGMY alone, GP+ alone, MY11/09 (MY) alone or MY/GP+ [<xref rid="B46-viruses-08-00028" ref-type="bibr">46</xref>
,<xref rid="B47-viruses-08-00028" ref-type="bibr">47</xref>
]. In addition, PGMY/GP+ amplicon length of 150 nucleotides (nt) falls within the average read length of 400 nt by Titanium pyrosequencing. First-round amplification applied Expand High Fidelity PCR System (Roche, Branchburg, NJ, USA). Ten percent of the product was then used for 2nd-round amplification. Sensitivity of HPV DNA detection reached a single copy based on an amplification of a serially diluted HPV16 L1 clone constructed from PGMY-amplified CaSki DNA by TOPO TA cloning (Invitrogen, Grand Island, NY, USA), which is in agreement with data published previously [<xref rid="B46-viruses-08-00028" ref-type="bibr">46</xref>
]. Inter- and intra-library agreements were over 90%, as evaluated previously [<xref rid="B48-viruses-08-00028" ref-type="bibr">48</xref>
,<xref rid="B49-viruses-08-00028" ref-type="bibr">49</xref>
], which insures reproducibility of HPV testing by deep sequencing. For Titanium amplicon deep sequencing, 5’ ends of PG5+ and PG6+ primers were conjugated with 25-mer nucleotide adaptors A (CGTATCGCCTCCCTCGCGCCATCAG) or B (CTATGCGCCTTGCCAGCCCGCTCAG), respectively. Multiplex identifier (MID) ten-mer nucleotides were added between adaptor A and the GP5+ sequence to allow for automated software identification of samples after pooling for multiplex deep sequencing [<xref rid="B50-viruses-08-00028" ref-type="bibr">50</xref>
]. Primer pairs produced HPV L1 amplicons of 106 nt excluding adaptors, MID and primers (<xref ref-type="fig" rid="viruses-08-00028-f001">Figure 1</xref>

Second-round PCR included denaturation at 95 °C for 2 min, followed by 40 cycles of 95 °C for 1 min, 56 °C for 1 min and 68 °C for 1 min, with a final extension at 68 °C for 10 min. Although 40 °C annealing temperature for GP5+/6+ PCR amplifications was established in 1995 [<xref rid="B45-viruses-08-00028" ref-type="bibr">45</xref>
], our analysis, using Oligo 5.0 (Molecular Biology Insights, Inc., Colorado Springs, CO, USA) of GP5+/6+ annealing efficiencies for all 37 HPV genotypes included in the LA probe set, defined the optimal median (QR) annealing temperature as 47 °C (46–48 °C) and the maximum median (QR) annealing temperature as 62 °C (60–65 °C). To increase PCR efficiency, reduce nonspecific amplification, and accommodate annealing between the HPV L1 region, the 10-mer barcode and the 25-mer adaptor incorporated into the primers, an annealing temperature of 56 °C, between optimal and maximum for all HPV types tested, was used. This annealing temperature was able to detect HPV56, which has the lowest optimal annealing temperature (44 °C) among the 37 HPV types included in LA probe set. HPV L1 DNA amplicon libraries were generated successfully in cross-sectional samples from 18 participants, 6 longitudinal samples from 2 individuals, cell lines CaSki and C-4 II, and an HPV16 L1 clone (<xref ref-type="app" rid="app1-viruses-08-00028">Table S1</xref>

<p>Standard operating procedures were followed at every step of PCR amplifications to prevent cross-contamination, and no template controls were always negative.</p>
<p>Gel-purified amplicons were sequenced from adaptor A using a Genome Sequencer FLX (454 Life Sciences, Branford, CT, USA) with Titanium chemistry (Roche) according to the manufacturer’s protocol in the University of Florida Interdisciplinary Center for Biotechnology Research (ICBR, Gainesville, FL, USA). Multiplex deep sequencing was performed on HPV L1 libraries pooled at equal molar ratio at the bead recovery step, a critical modification as pooling samples at the DNA level produced skewed sequencing output (data not shown). The first 14 samples were pooled in one region of an 8-region PicoTiter plate to obtain a median (QR) of 1,562 (792–1,831) raw reads per sample. To increase the sequence depth and accelerate the turnaround time in the ICBR Sequencing Core Facility, the second set of 11 samples, including 8 samples from 4 participants, 2 control cell lines, and 1 HPV16 molecular clone were sequenced in two regions of a 4-region PicoTiter plate to generate a median (QR) of 26,193 (16,586–36,771) raw reads per sample (<xref ref-type="app" rid="app1-viruses-08-00028">Table S1</xref>

. Raw reads generated from pooled libraries were de-multiplexed in Geneious Pro 5.6.5 (Biomatters Ltd., Auckland, New Zealand) using “Separate Reads by Barcode” function with 454 MIDS selected as the Barcode Set to assign sequences to each individual. Quality control steps were performed first in Geneious Pro 5.6.5 to exclude unassigned reads, reads inaccurately assigned to MIDs unused in multiplexing due to an incomplete MID, no MID, sequencing errors in the MID, reads with more than one mismatch in any of the primers, or reads with a sequence length outside the mean ± 2 SD range. Subsequent analysis in BioEdit (Ibis Biosciences, Carlsbad, CA, USA) identified and excluded reads with ambiguous nucleotide(s) or out-of-reading-frame indels. After quality control, a median (QR) of 1,441 (684–1,670) and 25,928 (16,444–36,038) quality sequences were obtained for the first 14 samples and the 2nd 11 samples, respectively, with correspondent median (QR) removal rate of 9.7% (8.0%–14.5%) and 1.4% (0.7%–3.4%) (<xref ref-type="app" rid="app1-viruses-08-00028">Table S1</xref>

<p>To assess deep sequencing errors, 25,928 quality L1 deep sequences from a molecular clone of HPV16 were aligned to an HPV16 reference sequence (GI│333031) using MUSCLE in Geneious package, followed by BioEdit (Ibis Biosciences, Carlsbad, CA, USA). Errors were evaluated using an in-house code. Overall sequencing error rate was 0.46% (46 errors/10,000 nucleotides) with 0.09%, 0.03%, 0.08% and 0.26% for transitions, transversions, and insertions or deletions (indels), respectively. After correction of indels, rate of misincorporation was 0.12% (12 errors per 10,000 nucleotides), which is 18 times lower than 2%, the maximum dissimilarity within an HPV genotype [<xref rid="B52-viruses-08-00028" ref-type="bibr">52</xref>

Raw deep sequencing reads generated from pooled HPV L1 libraries were separated and assigned to each individual according to MID sequence codes. Quality control removed low quality reads. Quality sequences of an HPV16 clone were aligned to HPV16 reference sequence (GI│333031) to study errors due to PCR and deep sequencing.

<p>With the rapid revolution in technology, NGS applied to HPV genotyping provides high sensitivity in capturing even low frequency types, reflecting unprecedented coverage of viral copies and almost no limit in the number of types detected in a sample by querying reference sequence databases [<xref rid="B72-viruses-08-00028" ref-type="bibr">72</xref>
,<xref rid="B74-viruses-08-00028" ref-type="bibr">74</xref>

,<xref rid="B76-viruses-08-00028" ref-type="bibr">76</xref>
]. NGS has opened up the opportunity to examine viral diversity, monitor persistence, fluctuation and evolution, discover new genotypes and survey vaccine response, which can be detailed at variant level [<xref rid="B74-viruses-08-00028" ref-type="bibr">74</xref>

,<xref rid="B78-viruses-08-00028" ref-type="bibr">78</xref>
]. Studies at the HPV variant level have clinical relevance since some HPV intra-type variants are geographically specific, associated with oncogenicity, or responsible for vaccine escape [<xref rid="B52-viruses-08-00028" ref-type="bibr">52</xref>
,<xref rid="B79-viruses-08-00028" ref-type="bibr">79</xref>

,<xref rid="B82-viruses-08-00028" ref-type="bibr">82</xref>
]. However, the spectrum of HPV genotypes identified by deep sequencing still relies on the primer system used for amplicon generation. </p>
<p>In this study, we applied nested PCR using PGMY, followed by GP+ primers, to generate HPV L1 amplicon libraries since PGMY/GP+ provided greater sensitivity and broader coverage of HPV genotypes compared to MY alone, PGMY alone, GP+ alone, or MY/GP+ [<xref rid="B46-viruses-08-00028" ref-type="bibr">46</xref>
,<xref rid="B47-viruses-08-00028" ref-type="bibr">47</xref>
]. Other pyrosequencing-based HPV-genotyping studies used single-round amplification with MY, PGMY, or GP+ primers [<xref rid="B72-viruses-08-00028" ref-type="bibr">72</xref>
,<xref rid="B74-viruses-08-00028" ref-type="bibr">74</xref>

,<xref rid="B83-viruses-08-00028" ref-type="bibr">83</xref>
]. In addition, a 150 nt amplicon length falls within the average read length of 400 nt by Titanium pyrosequencing. Consensus primer systems all suffer from certain amplification bias towards HPV genotypes with greater priming efficiency [<xref rid="B44-viruses-08-00028" ref-type="bibr">44</xref>

,<xref rid="B85-viruses-08-00028" ref-type="bibr">85</xref>
]; thus, the percent of sequences may not correlate with the actual amount of virus present and cannot serve as a quantitative measure of viral population structure [<xref rid="B72-viruses-08-00028" ref-type="bibr">72</xref>
]. Primer design remains a critical factor for HPV genotyping by deep sequencing. Application of rolling circle amplification using random hexamer followed by deep sequencing may provide unbiased amplification of episomal HPV particles but misses genotypes integrated into the cell genome, which are closely correlated with viral persistence, cancer development, increased carcinogenesis and poor therapy response [<xref rid="B86-viruses-08-00028" ref-type="bibr">86</xref>
,<xref rid="B87-viruses-08-00028" ref-type="bibr">87</xref>

,<xref rid="B95-viruses-08-00028" ref-type="bibr">95</xref>
]. </p>
<p>HPV genotyping of deep sequences relied mainly on querying to NCBI Blastn [<xref rid="B72-viruses-08-00028" ref-type="bibr">72</xref>
,<xref rid="B75-viruses-08-00028" ref-type="bibr">75</xref>
]. NCBI Blastn can only query a single sequence per blast search and thus cannot accommodate large sequence data sets. PaVE PV Specific Blastn is able to handle multiple sequences per blast search, but the capacity is far less than 10 Mb per run provided by HPV-QUEST, and genotyping results returned by PaVE PV Specific Blastn require further processing and organization. HPV-QUEST, a web-based genotyping system we developed [<xref rid="B33-viruses-08-00028" ref-type="bibr">33</xref>
], includes 150 annotated cutaneous and mucosal HPV reference sequences with L1 regions and updated nomenclatures, processes up to 10 Mb of sequences (around 6500 sequences of 100 nt) per run, returns results within one to two minutes, and outputs results in excel and text format, including blast score, e-value, local identity (the percentage of matched nucleotides within the alignment region), genus, species, genotype, infection site (mucosal or cutaneous or both), risk (high or low or unknown), accession number and gene identification number of reference sequence, and alignment of query sequence with reference sequence. Query sequences failing to align with any reference sequences in the HPV-QUEST are designated as “ND”. Any sequences that fail to blast, have low local identity, or with an e-value >1e−15 are considered low quality, a new recombination, or a new genotype. With our NGS/HPV-QUEST genotyping system, large data sets of L1 sequences were easily generated and managed, and were classified rapidly and accurately with stringent quality assurance. The repertoire of HPV genotypes that can be classified unambiguously was extended because all published HPV genotypes were included among the reference sequence database in HPV-QUEST, and analysis was not restricted by availability of HPV type-specific probes. Nevertheless, the consensus nature of PGMY/GP+ primers used in generating amplicon libraries were designed to cover a broad spectrum of HPV types with genetic dissimilarity of at least 10%, rendering amplification bias towards certain HPV types unavoidable, similar to probe-based assays. Less than optimal specificity of GP+ primers for HPV genomes species 3 [<xref rid="B96-viruses-08-00028" ref-type="bibr">96</xref>
] likely accounts in part for lack of concordance between LA and deep sequencing for HPV typing in some samples. Previous studies suggested that PCR amplification-mediated bias is more due to differential primer-template annealing efficiencies of consensus primers than input template copies [<xref rid="B97-viruses-08-00028" ref-type="bibr">97</xref>
,<xref rid="B98-viruses-08-00028" ref-type="bibr">98</xref>
,<xref rid="B99-viruses-08-00028" ref-type="bibr">99</xref>
].</p>
<p>Sequencing allowed the identification of signature polymorphisms among L1 genotypes in more than 75% of individuals in this exploratory study with relatively small sample size, providing a framework to apply to future studies of HPV clearance, persistence, and super-infection by variants of the same HPV genotypes in a larger cohort. In addition, other regions of the HPV genome that may provide more robust molecular information can be incorporated into a deep sequencing platform to track genotypes over time or evaluate HPV gene expression [<xref rid="B100-viruses-08-00028" ref-type="bibr">100</xref>
]. A high frequency of nucleotide variants differing from reference variants among a range of HPV genotypes failed to be typed by LA, potentially reflecting an inefficient hybridization between HPV L1 regions with polymorphism and primers and/probes used in LA.</p>
<p>In the current study, deep sequencing was applied to define the range of HPV genotypes in asymptomatic individuals. Our data clearly demonstrate that healthy men can carry a range of high-risk and/or low-risk types HPV genotypes, including the vaccine types. Infection by multiple-type high-risk HPV, alone or in combination with low-risk genotypes, is a significant clinical issue for prognosis or treatment for a variety of HPV cancers [<xref rid="B4-viruses-08-00028" ref-type="bibr">4</xref>

]. Deep sequencing technology combined with an efficient analysis pipeline offers a platform that can detect HPV genotypes at low frequency in the population, that enables the discovery of the extent to which a repertoire of HPV genotype(s) may relate to subsequent development of disease, that can extend the unambiguous classification of HPV genotypes, and that can provide more robust data about prevalence, dynamics, and competition among genotypes in an ecosystem. Sequence data also provides the basis to implement phylogenetic tools to both assess the organization of HPV genomes within an individual, among transmission pairs, or across geographic locations, and investigate the relationship among new HPV sequences with reference genotypes.</p>
