Gupta A, Salway T, Jessani A. Cost-related avoidance of oral health service utilization among lesbian, gay, and bisexual individuals in Canada. J Public Health Dent 2023; 83:254-264. [PMID: 37329179 DOI: 10.1111/jphd.12574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Revised: 04/12/2023] [Accepted: 05/17/2023] [Indexed: 06/18/2023]
Abstract
OBJECTIVES This study estimates the frequency of cost-related oral health service avoidance (CROHSA) among lesbian, gay, and bisexual (LGB) individuals in Canada relative to heterosexual persons. METHODS Heterosexual and sexual minority individuals in Canada were compared using the national probability-based Canadian Community Health Survey 2017-2018. Logistic regression was used to quantify associations between LGB status and CROHSA. Mediators were tested following Andersen's behavioral model of health service utilization and included partnership status, oral health status, presence of dental pain, educational attainment, insurance status, smoking status, general health status, and personal income. RESULTS From our sample of 103,216 individuals, 34.8% of LGB individuals reported avoiding oral health care due to cost compared to 22.7% of heterosexual persons. Disparities were most pronounced among bisexual individuals (odds ratio [OR] 2.29 95% confidence interval [CI] 1.42, 3.49). Disparities persisted despite adjustment for confounding using age, gender/sex, and ethnicity (OR 2.23 95% CI 1.42, 3.49). Disparities were fully mediated by eight hypothesized mediators namely, educational attainment, smoking status, partnership status, income, insurance status, oral health status, and the presence of dental pain (OR 1.69 95% CI 0.94, 3.03). In contrast, lesbian/gay individuals did not have elevated odds of experiencing CROHSA compared to heterosexual individuals (OR 1.27 95% CI 0.84, 1.92). CONCLUSION CROHSA is elevated for bisexual individuals relative to heterosexual individuals. Targeted interventions should be explored to improve oral healthcare access among this population. Future research should assess the role of minority stress and social safety on oral health inequities among sexual minority groups.

Abstract
The present study aimed to evaluate the association of genital and oral HPV infection among different sexual practices in both sexes. In total, 6388 unvaccinated men and women aged 16–25 years from all state capitals of Brazil were enrolled in through primary care services between September 2016 and November 2017. Genital and oral HPV genotyping was performed using the Roche Linear Array. Poisson regression analysis with robust variance was conducted to examine factors associated with overall HPV infection. A higher prevalence of genital HPV was found in women who practiced oral sex (57.85%) and in men who practiced all types of sex (65.87%). However, having more sexual partners and being younger were more important than the type of sex practiced. HPV 6 (7.1%) and 16 (10.5%) were significantly more prevalent in women who practiced oral sex, while HPV 6 (23.96%) and 11 (21.49%) were more prevalent in men who practiced anal sex. The type of sex was not associated with oral HPV prevalence. Genital and oral HPV infection were not associated by different sexual practices in the studied population.

Abstract
Oral infection by Human Papillomavirus (HPV) has recently gained great attention because of its involvement in the development of a subset of head and neck squamous cell carcinoma. The role of specific Alpha-HPVs in this regard has been well established, whereas the contribution of other genera is under investigation. Despite their traditional classification as “cutaneous” types, Beta and Gamma HPVs are frequently detected in oral samples. Due to the lack of a standardized protocol, a large variety of methodologies have been used for oral sample collection, DNA extraction, HPV detection and genotyping. Laboratory procedures influence the evaluation of oral HPV prevalence, which largely varies also according to the population characteristics, e.g., age, gender, sexual behavior, Human Immunodeficiency Virus (HIV) status. Nevertheless, oral infection by Beta and Gamma HPVs seems to be even more common than Alpha-HPVs. The latter is 5–7% in the general population, and increases up to 30% approximately in HIV-infected men who have sex with men. Despite major advances in the evaluation of oral HPV prevalence, its natural history is still little understood, especially for Beta and Gamma HPVs. The latest technologies, such as Next Generation Sequencing (NGS), can be exploited to gain new insights into oral HPV, and to improve the identification of novel HPV types.

High-risk HPV genotypes in Zimbabwean women with cervical cancer: Comparative analyses between HIV-negative and HIV-positive women. PLoS One 2021; 16:e0257324. [PMID: 34582476 PMCID: PMC8478215 DOI: 10.1371/journal.pone.0257324] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Accepted: 08/30/2021] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND High-risk human papillomavirus HPV (HR-HPV) modifies cervical cancer risk in people living with HIV, yet African populations are under-represented. We aimed to compare the frequency, multiplicity and consanguinity of HR-HPVs in HIV-negative and HIV-positive Zimbabwean women. METHODS This was a cross-sectional study consisting of women with histologically confirmed cervical cancer attending Parirenyatwa Group of Hospitals in Harare, Zimbabwe. Information on HIV status was also collected for comparative analysis. Genomic DNA was extracted from 258 formalin fixed paraffin embedded tumour tissue samples, and analysed for 14 HR-HPV genotypes. Data was analysed using Graphpad Prism and STATA. RESULTS Forty-five percent of the cohort was HIV-positive, with a median age of 51 (IQR = 42-62) years. HR-HPV positivity was detected in 96% of biospecimens analysed. HPV16 (48%), was the most prevalent genotype, followed by HPV35 (26%), HPV18 (25%), HPV58 (11%) and HPV33 (10%), irrespective of HIV status. One third of the cohort harboured a single HPV infection, and HPV16 (41%), HPV18 (21%) and HPV35 (21%) were the most prevalent. HIV status did not influence the prevalence and rate of multiple HPV infections (p>0.05). We reported significant (p<0.05) consanguinity of HPV16/18 (OR = 0.3; 95% CI = 0.1-0.9), HPV16/33 (OR = 0.3; 95% CI = 0.1-1.0), HPV16/35 (OR = 3.3; 95% CI = 2.0-6.0), HPV35/51 (OR = 6.0; 95%CI = 1.8-15.0); HPV39/51 (OR = 6.4; 95% CI = 1.8-15), HPV31/52 (OR = 6.2; 95% CI = 1.8-15), HPV39/56 (OR = 11 95% CI = 8-12), HPV59/68 (OR = 8.2; 95% CI = 5.3-12.4), HPV66/68 (OR = 7; 95% CI = 2.4-13.5), independent of age and HIV status. CONCLUSION We found that HIV does not influence the frequency, multiplicity and consanguinity of HR-HPV in cervical cancer. For the first time, we report high prevalence of HPV35 among women with confirmed cervical cancer in Zimbabwe, providing additional evidence of HPV diversity in sub-Saharan Africa. The data obtained here probes the need for larger prospective studies to further elucidate HPV diversity and possibility of selective pressure on genotypes.

Abstract
BACKGROUND People living with HIV (PLWH) are more likely to smoke and harbor oral human papillomavirus (HPV) infections, putting them at higher risk for head and neck cancer. We investigated effects of HIV and smoking on oral HPV risk. METHODS Consecutive PLWH (n = 169) and at-risk HIV-negative individuals (n = 126) were recruited from 2 US health centers. Smoking history was collected using questionnaires. Participants provided oral rinse samples for HPV genotyping. We used multivariable logistic regression models with interaction terms for HIV to test for smoking effect on oral HPV. RESULTS PLWH were more likely to harbor oral HPV than HIV-negative individuals, including α (39% vs 28%), β (73% vs 63%), and γ-types (33% vs 20%). HIV infection positively modified the association between smoking and high-risk oral HPV: odds ratios for smoking 3.46 (95% confidence interval [CI], 1.01-11.94) and 1.59 (95% CI, .32-8.73) among PLWH and HIV-negative individuals, respectively, and relative excess risk due to interaction (RERI) 3.34 (95% CI, -1.51 to 8.18). RERI for HPV 16 was 1.79 (95% CI, -2.57 to 6.16) and 2.78 for β1-HPV (95% CI, -.08 to 5.65). CONCLUSION Results show tobacco smoking as a risk factor for oral HPV among PLWH.

Abstract
Human immunodeficiency virus (HIV) infections are spiking in Chinese young men who have sex with men (MSM). To explore alterations in the salivary microbiome and its correlation with demographic characteristics, CD4+ T cell count and viral load (VL) in HIV infections, samples of unstimulated whole saliva were analyzed by 16S rRNA gene sequencing using the Illumina MiSeq platform in 20 HIV newly infected patients before the initiation of antiretroviral therapy (ART) and at three and six months after, and in 20 age- and gender-paired healthy Chinese people. The results showed that the alpha diversity of salivary microbiota in HIV infections did not show differences from the healthy controls, but was reduced after six months under ART treatment. Comparative analysis revealed that Streptococcus was enriched in HIV-infected individuals, while Neisseria was enriched in the healthy control group. After effective ART, the salivary microbiota composition was not completely restored, although some microbiota recovered. In addition, we found Provotella_7, Neisseria and Haemophilus were correlated negatively with CD4+ T cell count, while Neisseria was correlated positively with VL. We conclude that HIV infections experience a dysbiosis of the salivary microbiome. The salivary microbiome test could be a substitute for the blood tests in the diagnosis and prognosis of diseases.

Human Papillomavirus Prevalence in Oral and Oropharyngeal Rinse and Gargle Specimens of Dental Patients and of an HIV-Positive Cohort from Pretoria, South Africa. Adv Virol 2020; 2020:2395219. [PMID: 32908509 PMCID: PMC7471795 DOI: 10.1155/2020/2395219] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 05/27/2020] [Accepted: 06/24/2020] [Indexed: 12/17/2022] Open
Abstract
Introduction Studies on HPV prevalence in the head and neck region of South Africans are sparse. Of the available reports in the literature, there were no studies on the association between HPV-DNA presence in the mouth and oropharynx in relation to high-risk behaviours such as oral sex practice or tobacco and alcohol use. Materials and Methods Following ethical clearance and informed consent, patients attending a regional HIV-management clinic and patients attending a dental hospital were recruited to this study. The participants completed an interview-based questionnaire obtaining demographic information, data on HIV serostatus, and behavioural data including sexual practices and tobacco and alcohol use, and a rinse-and-gargle specimen was taken. Specimens were analysed for HPV DNA on 3 separate PCR/qPCR platforms. Statistical analyses were performed for associations between the study group and categorical variables, HPV status, and data from the questionnaires. Results Of 221 participants, 149 were from a general population and 72 from the HIV-management clinic. Smokers comprised 29.4% of the sample, and 45.2% of participants reported to have ever used alcohol. Open mouth kissing during teenage years was confirmed by 64.7% of participants, 40.3% have given oral sex with their mouth, and 44.8% confirmed to have received oral sex from their partner's mouth. Seven participants (3.2%) had detectable α-HPV DNA, and 1 (0.4%) had detectable β-HPV DNA in their rinse-and-gargle specimens. Two participants were from the HIV-management clinic and 6 from the general dental population (overall 3.6%). Conclusion Five high-risk HPV, 2 low-risk HPV, and one β-HPV types were detected. The low prevalence of 3.6% compares well to similar studies in different cohorts studied in South Africa and falls within the global oral/oropharyngeal prevalence spectrum. Only 4 participants, all from the HIV-management clinic, had palatine tonsils. No significant relationships were found between HPV presence and demographic data or sexual, oral sexual, tobacco use, or alcohol use, and no associations were seen with numbers of sexual and oral-sex partners.

Oral testing for high-risk human papillomavirus DNA and E6/E7 messenger RNA in healthy individuals at risk for oral infection. Cancer 2019; 125:2587-2593. [PMID: 31034590 DOI: 10.1002/cncr.32152] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2018] [Revised: 03/04/2019] [Accepted: 03/29/2019] [Indexed: 01/21/2023]
Abstract
BACKGROUND Testing for oral high-risk human papillomavirus (HPV) DNA may be useful for identifying individuals at increased risk for HPV-driven oropharyngeal cancer (OPC). However, positivity for HPV DNA provides no information on the transforming potential of the infection. In contrast, the detection of high-risk HPV E6/E7 messenger RNA (mRNA) may help to identify clinically significant infections because of the indispensable role of E6/E7 viral oncoproteins in the carcinogenic process. METHODS Oral rinses were collected with a mouthwash from cancer-free individuals at increased risk for oral HPV infection. High-risk HPV DNA and mRNA were evaluated via the testing of the oral rinses with the Linear Array HPV genotyping test and the Aptima HPV assay, respectively. RESULTS Overall, 310 subjects with no clinical evidence of lesions of the oral cavity and oropharynx were included in the study. Thirty-three (10.6%) harbored high-risk HPV DNA in their oral rinse. These cases, together with 10 random samples negative for high-risk HPV DNA, were tested with the Aptima assay. A valid result was obtained for 41 of the 43 specimens (95.3%). Among the 31 cases that were positive for high-risk HPV DNA and had a valid Aptima result, 4 (12.9%) were positive for HPV mRNA. HPV mRNA was not detected in any of the samples negative for high-risk HPV DNA. CONCLUSIONS HPV mRNA is detectable in oral rinses of cancer-free subjects. Oral HPV mRNA testing may be useful in the screening and/or early detection of HPV-driven OPC by possibly identifying active and transforming oral infections. The testing of individuals at increased risk for HPV-related OPC via simply and noninvasively collected oral specimens is an attractive option for future screening strategies.

Abstract
Background The number of oropharyngeal lesions caused by HPV (Human papillomavirus) has been increasing worldwide in the past years. In spite of the clinical relevance of HPV infection in the anogenital tract of HIV-positive patients, the relevance of oropharynx HPV infection in these patients is not clear. The aim of the present study was to detect HPV infection, and clinical and cytological changes in the oropharynx of HIV-positive patients. Methods Samples collected from the oropharynx of 100 HIV-positive patients were subjected to hybrid capture (HC), conventional and liquid-based cytology. Clinical data were also collected to investigate the relation with HPV status. Results High and low-risk types of HPV were present in 8% and 16.7% of the total sample. The mean ± sd (maximum-minimum) of the relative ratio light unit (RLU)/cutoff (CO) was 2.94 ± 2.58 (1.09–7.87) and 1.61 ± 0.65 (1.07–2.8) for high- and low-risk-HPV, respectively. By cytology, dysplasia was not detected, but atypical squamous cells of undetermined significance (ASC-US) were diagnosed in two samples. No clinical change, suggestive of dysplasia/cancer, was detected. Conclusion Our study was able to detect and characterize HPV infection by hybrid capture, which may represent a good tool for screening and follow-up of HPV in the studied population. The frequency and viral load of HPV were low. Neither clinical nor cytological changes suggestive of dysplasia/neoplasia were observed in oropharynx of HIV-positive patients.

Abstract
BACKGROUND Oral high-risk human papillomavirus (HR-HPV) infections are frequent and persistent among the HIV-positive population and are associated with an increased risk for head and neck cancer (HNC). In this study, we sought to determine the incidence, persistence and clearance of HPV infections in oral and oropharyngeal samples from HIV/AIDS subjects. METHODS A longitudinal, observational and analytical study was performed with an ongoing cohort of HIV/AIDS subjects in Mexico City (September 2013-February 2015). The study was approved by institutional committees, and demographic and clinical data were registered. At the baseline and three-month visits, oral examinations and cytobrush samples were obtained. DNA was purified, quantified and used to detect an HPV-L1 gene fragment by nested PCR, using MY09/MY11 and GP5 + /GP6 + primers. HPV DNA products were purified, sequenced and typed according to HPV databases. Risk factors were assessed, and a multivariate modelling approach was used to determine independent effects. RESULTS This study included 97 HIV/AIDS individuals (91% men [86.4% of which are men who have sex with men], median age: 36 years, 72.2% under HAART). From the baseline visit, HPV was observed in 55.7% (HR-HPV: 26.8%; HPV-18: 24.1%), with a higher HPV-positive samples for smokers (61.1 vs 32.6%, P = .005). The three-month overall HPV incidence was 33.9%; type-specific HPV persistence was 33.3% (HR-HPV: 13.3%); and 13 of the 33 (39.4%) baseline HPV-positive individuals cleared the infection (HR-HPV: 53.8%). CONCLUSIONS Although HR-HPV persistence was low, and clearance of the infection was observed in most cases, a close follow-up is necessary, given the increase in HNC among HIV-subjects, particularly HPV-related cancer.

Abstract
Background Oral Human Papillomavirus (HPV) infection is rare in the general population but common in high-risk individuals. Recent data indicate that oral HPV is associated with the development of head and neck carcinomas. HPV16 infection, in particular, increases the risk of oropharyngeal cancer. Methods We evaluated oral HPV prevalence and determinants of infection in cancer-free HIV-infected and uninfected men who have sex with men (MSM) recruited among attendees of an STI/HIV centre. Oral rinse and gargles were collected using a mouthwash and analyzed with the Linear Array HPV Genotyping Test. Socio-demographic and behavioral data were collected through face-to-face interviews. Results Overall, 170 MSM participated: 98 HIV-uninfected and 72 HIV-infected (91.7% under cART). Oral HPV was detected in 17.3% and 27.8% of the subjects, respectively (p = 0.13). Non-carcinogenic HPVs were significantly more common among HIV-infected MSM (18.1% vs. 5.1%, p = 0.01). Prevalence of the HPV types included in the quadrivalent HPV vaccine was similar (6.1% vs. 8.3% for the HIV-negative and positive MSM, respectively, p = 0.76). HPV16 was the most frequent type in HIV-negative (5.1%), and HIV-positive individuals, in the latter group together with HPV18, 72 and 84 (4.2% each). Older age at first sex (AOR: 4.02, 95% CI: 1.17–13.86 for those older than 18 years of age at first intercourse, p = 0.027) and a higher lifetime number of receptive oral sex partners (AOR: 9.14, 95% CI: 2.49–33.62 for those with >50 compared to ≤50 partners, p<0.001) were determinants of oral HPV among HIV-infected MSM. Conclusion Oral HPV infection among MSM attending an urban STI center is very frequent compared to the general population. Sexual behavior appears to be the major determinant of infection among the HIV-infected individuals.

Abstract
In this study, high-risk HPV (hrHPV) incidence, prognostic biomarkers, and outcome were assessed in HIV-positive (case) and HIV-negative (control) patients with head and neck squamous cell cancer (HNSCC). HIV-positive cases were matched to controls by tumor site, sex, and age at cancer diagnosis. A tissue microarray (TMA) was constructed and DNA isolated from tumor tissue. MultiPlex-PCR MassArray, L1-PCR, and in situ hybridization were used to assess hrHPV. TMA sections were stained for p16ink4a, TP53, RB, CCND1, EGFR, and scored for intensity and proportion of positive tumor cells. The HNSCC cohort included 41 HIV-positive cases and 41 HIV-negative controls. Tumors from 11 of 40 (28%) cases, and 10 of 41 (24%) controls contained hrHPV. p16 expression, indicative of E7 oncogene activity, was present in 10 of 11 HPV-positive cases and 7 of 10 HPV-positive controls. Low p16 and high TP53 expression in some HPV-positive tumors suggested HPV-independent tumorigenesis. Survival did not differ in cases and controls. RB expression was significantly associated with poor survival (P = 0.01). High TP53 expression exhibited a trend for poorer survival (P = 0.12), but among cases, association with poor survival reached statistical significance (P = 0.04). The proportion of HPV-positive tumors was similar, but the heterogeneity of HPV types was higher in the HIV-positive cases than in HIV-negative controls. High RB expression predicted poor survival, and high TP53 expression was associated with poorer survival in the HIV-positive cases but not HIV-negative controls. IMPLICATIONS HIV infection did not increase risk of death from HNSCC, and HPV-positive tumors continued to be associated with a significantly improved survival, independent of HIV status.

Abstract
BACKGROUND The epidemiology of oral human papillomavirus (HPV) infection in men who have sex with men (MSM) differs from anogenital HPV infection. The impact of HPV vaccination has, to date, largely focussed on anogenital outcomes. Vaccination of MSM in the UK has been recommended and, if implemented, baseline estimates of oral HPV prevalence will be useful. METHODS We searched Medline, Embase and psycINFO databases for studies reporting prevalence, incidence, and clearance of oral HPV infection in MSM. We performed a random-effects meta-analysis and meta-regression on prevalence estimates and summarised within-study risk factors for oral HPV DNA detection and incidence/clearance rates. We also performed a meta-analysis of the effect of MSM on oral HPV prevalence compared to heterosexual men. RESULTS 26 publications were identified. The pooled prevalence of oral HPV16 from twelve estimates was 3.0% (95%CI 0.5-5.5) in HIV-negative and 4.7% (95%CI 2.1-7.3) in HIV-positive MSM. Median age of study participants explained 38% of heterogeneity (p<0.01) in HPV prevalence estimates (pooled = 17% and 29% in HIV-negative and HIV-positive, respectively; 22 estimates). Nine studies compared MSM to heterosexual men and found no difference in oral HPV prevalence (pooled OR 1.07 (95%CI 0.65-1.74)). The clearance rate was higher than incidence within studies. Type-specific concordance between oral and anogenital sites was rare. CONCLUSION There was substantial heterogeneity between estimates of oral HPV prevalence in MSM populations that was partly explained by HIV status and median age.

Abstract
Anogenital warts (AGW) are one of the most common sexually transmitted diseases worldwide. The determination of groups vulnerable to contracting anogenital warts (AGW) leads to the development of policies for disease control and of prevention programs. The aim of our study was to investigate the demographical features and risk factors of Turkish patients with AGW. This study included 200 patients with AGW and 200 healthy individuals as a control group. The age, gender, education and marital status, age of first sexual intercourse, number of sexual partners, sexual orientation, and smoking status were recorded in both groups. In this study, 88% of the patients were male, and 12% were female. The mean age of the patients was 35.21±0.77 years, and the majority of patients were below 35 years old (63%). Furthermore, 46.0% of the patients were educated at the university level, and 33.5% had graduated high school. No significant differences were found based on sexual orientation or condoms between the patient and control groups. In the patient group, the mean age of first sexual intercourse was significantly earlier, and the number of single individuals and sexual partners were significantly higher. Also, 61% of the patients were current smokers, which was significantly higher than the control group. The duration of smoking and the duration of AGW were found to be correlated. All patients were tested for anti-HIV antibodies, and only one patient was found to be infected. AGW were more common in patients younger than 35 years old, among men, and among those who had graduated from high school or university. Early age of first sexual intercourse, a high number of sexual partners, being single, and smoking were also risk factors for the development of anogenital warts.

Abstract
INTRODUCTION Infection with Human papillomavirus (HPV) has been reported as one of the most prevalent agent sexually transmitted diseases, but its true prevalence in men is not precisely known, mainly due to the near absence of symptoms. Moreover, few studies evaluating the post-vaccination immune response have been performed to date in men, hence the hypotheses tested in this study can be important to enable a better understanding of both the immunopathogenesis and the response to vaccination in HIV-infected patients, and to help in the elaboration of strategies of vaccination against HPV in the HIV-infected population. OBJECTIVES To analyze the specific response to antigens of HPV vaccine in HIV-infected men. METHODS A total of 25 HIV-infected male patients who met the inclusion criteria during the data collection period were vaccinated; however, six (30%) had anti-HPV at baseline, and were not considered further in the analysis. Therefore, 19 HIV-infected individuals were included in the study, along with five healthy, HPV-seronegative controls. RESULTS Patients infected with HIV-1 were subdivided into two groups, A and B, according to their T CD4 cells count at the time of vaccination, namely: Group A: CD4>500; Group B: CD4<500. The proportion of seroconversion after immunization with three doses of a bivalent anti-HPV vaccine was 92%. CONCLUSION HIV-infected patients as well as HIV negative controls responded to anti-HPV vaccination, regardless of their T CD4 cells count and HIV plasma viral load. These results demonstrate that anti-HPV immunization in HIV-infected males is effective and should be encouraged, thus helping to decrease the risk of infection, mortality and morbidity of diseases associated with HPV in men.

Abstract
In 2010, a new mouse papillomavirus, MmuPV1, was discovered in a colony of NMRI- Foxn1(nu)/Foxn1(nu) athymic mice in India. This finding was significant because it was the first papillomavirus to be found in a laboratory mouse. In this paper we report successful infections of both dorsal and ventral surfaces of the rostral tongues of outbred athymic nude mice. We also report the observation that the base of the tongue, the area of the tongue often targeted by cancer-associated high-risk papillomavirus infections in humans, is especially susceptible to infection. A suitable animal model for the study of oral papillomavirus infections, co-infections, and cancers has long been sought. The work presented here suggests that such a model is now at hand.
