Abstract
Human papillomavirus (HPV) is a small DNA virus that infects the basal keratinocytes of squamous epithelium in the skin, and in the oral and genital mucosa. Smoking and sexual behavior have been recognized as significant risk factors for oral HPV infection. In the present review, the findings of recent studies of oral HPV infection in relation to periodontitis are discussed, as well as periodontopathic bacteria and periodontal herpes virus. Previous research suggests that HPV localizes to the inflammatory periodontal tissue. Inflammatory periodontal pockets may thus act as a reservoir for HPV. The interactions between HPV and periodontopathic bacteria remain unclear, but it is hypothesized that oral HPV infection may be related to a characteristic oral microbiome. Smoking is associated with HPV and periodontitis, as smoking induces destruction of periodontal tissue and suppresses the host defense, allowing HPV to infect periodontal tissue. Carcinogenic HPV and periodontitis may lead to the development of oral cavity cancer. However, oral HPV E6/E7 expression (transcriptionally active HPV) has not yet been fully investigated in patients with periodontitis. Collectively, the evidence suggests that oral HPV prevalence may be associated with periodontitis. The effect of clinical factors (age, sex, smoking, immunosuppressive condition and vaccination) on oral HPV DNA prevalence should be considered when clarifying the relationship between oral HPV and periodontitis. Additionally, the sampling method should be carefully chosen to directly detect HPV DNA in periodontal tissues.

Oral and laryngeal HPV infection: Incidence, prevalence and risk factors, with special regard to concurrent infection in head, neck and genitals. Vaccine 2021; 39:2344-2350. [PMID: 33812740 DOI: 10.1016/j.vaccine.2021.03.047] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 03/09/2021] [Accepted: 03/10/2021] [Indexed: 12/20/2022]
Abstract
This review focuses on the importance of oral and laryngeal HPV infection which is present in majority of sexually active individuals at least once in their lifetime. Despite testing, still little is known about prevalence rates, determinants and, especially, the concurrent HPV infection in head and neck, and genitals. The purpose of this review is to clarify some issues of oral HPV incidence, prevalence, and to demonstrate the difficulties in identification of asymptomatic oral HPV carriers. The main premise to take up this topic is the high and still increasing risk for development of oropharyngeal cancer, and potential benefit from screening strategies, education programs and HPV vaccination. Transmission of HPV to the oral cavity and oropharynx is hypothesized to occur mainly through sexual contact. The exposure of oropharyngeal mucosa to HPV infection with consequence of increased risk for oropharyngeal carcinoma depends on specific sexual behavior. Male gender, older age, race or ethnicity, oral hygiene and current cigarette smoking are independently associated with any prevalent oral HPV infection.

Abstract
Papillomaviruses are one of the oldest viruses known, dating back 330 million years. During this long evolution, human papillomaviruses (HPV) have developed into hijackers of human cellular and immune systems in which they replicate and remain silent. Systematic studies on oral HPV infections and their outcomes are still scarce. Oral HPV infections have been linked to sexual behaviour, but recent evidence supports their horizontal, mouth‐to‐mouth, transmission. Most HPV infections in infants are acquired vertically from the mother during the intrauterine period, during delivery, or later via saliva. The best‐known benign clinical manifestations of HPV infection are oral papilloma/condyloma and focal epithelial hyperplasia. Evidence is emerging which suggests that some oral HPV infections might persist. Persistent HPV infection is mandatory for HPV‐associated malignant transformation. However, progression of HPV‐induced lesions to malignancy requires additional cofactors. In the early 1980s, we provided the first evidence that a subset of oral cancers and other head and neck cancers might be causally linked to HPV infection. This review summarizes current knowledge on the virus itself, its transmission modes, as well as the full spectrum of oral HPV infections – from asymptomatic infections to benign, potentially malignant oral lesions, and squamous cell carcinoma.

Abstract
Objectives: Reffering to an increase in cervical cancer in the recent years, rapid, sensitive and economical detection of human papillomaviruses (HPVs) as causative agents of cervical cancer is important. The traditional methods for the detection of HPVs in cervical cancer, such as pap smear, suffer from limitation and PCR has a potential to overcome the limitaitons. The purpose of present research work was to identify the five important strains of HPV (16, 18, 31, 33 and 45) simultaneously by Multiplex PCR application. Methods: Study was done on 100 cervical lesions of women. DNA was extracted from specimens by a genomic DNA purification kit. A 5-plex PCR was developed for the simultaneous detection of major HPV. Five pair of new primers was designed for detection of HPV 16, 18, 31, 33 and 45 by Multiplex PCR. Results: Among the 100 evaluated samples, 82 were found positive to HPVs. In the meantime the highest rate of infection was for HPV 16. Also 30 of HPV positive samples had infections with two or more HPV types. Conclusion: Multiplex PCR assay used in present study can provide a rapid, sensitive and economical method for detection of viral infections and is applicable to small volumes of vaginal samples.

Abstract
OBJECTIVES Squamous cell carcinoma (SCC) is the most common oral malignancy, and verrucous carcinoma (VC) is a less invasive type of SCC. Leukoplakia (LP) is the most frequent premalignant lesion in the oral cavity. The human papillomavirus (HPV) has been recognized as one of the etiologic factors of these conditions. The association of anogenital and cervical cancers with HPV particularly its high-risk subtypes (HPV HR) has been demonstrated. The purpose of our study was to investigate the hypothetical association between HPV and the mentioned oral cavity lesions. METHODS One hundred and seventy-three samples (114 SCCs, 21 VCs, 20 LPs) and 18 normal mucosa samples (as a control group) were retrieved from the Department of Oral and Maxillofacial Pathology of Mashhad Dental School, Iran. The association of HPV genotypes in LP, VC, and SCC was compared to normal oral mucosa using the polymerase chain reaction. RESULTS The results showed the absence of HPV in normal mucosa and LP lesions. In three samples of VC (14.3%), we observed the presence of HPV HR (types 16 and 18). All VCs were present in the mandibular ridge of females aged over 65 years old. No statistically significant correlation between HPV and VC was observed (p=0.230). Additionally, 15 (13.1%) SCCs showed HPV positivity, but this was not significant (p=0.830). The prevalence of SCC was higher on the tongue with the dominant presence of less carcinogenic species of HPV (types 6 and 11). A statistically significant association was not observed between HPV and SCC or VC in the oral cavity. CONCLUSION More studies are necessary to better understand the relationship between HPV and malignant/premalignant oral cavity lesions.

Abstract
Limited data exist regarding whether a high-risk human papillomavirus (HR-HPV) infection increases the risk of developing renal cell carcinoma. The aim of this study was to investigate whether HPV infection has a role in the pathogenesis or development of a certain histological subtype of renal cell carcinoma. Formalin-fixed paraffin-embedded (FFPE) specimens of 122 patients with histopathologically proven renal cell carcinoma and their respective peritumoral tissues were examined. The presence of HPV-DNA was determined by a combination of MY/GP+ consensus primers and HPV-16/18 type specific nested PCRs followed by direct sequencing. Catalyzed signal-amplified colorimetric in situ hybridization (CSAC-ISH) technique was applied to determine the physical status of viral genome. The expression of p16INK4a and HPV L1 capsid proteins was evaluated using immunohistochemistry. HPV genome was detected in 37 (30.3%) tumor specimens and their four (4.1%) corresponding peritumoral tissues. HPV-18 was the most common viral type identified followed by HPV-16 and 58. Immunoexpression of p16INK4a was detected in 24 (20.3%) cases. Data analysis showed a significant correlation between p16INK4a expression and the presence of HR-HPV DNA (P < 0.001). CSAC-ISH analysis confirmed HR-HPV infection in 45% of tumors, which were previously tested positive for HPV-DNA. Diffuse signal pattern was identified in 15 (83.3%) samples whereas a mixed pattern of diffuse and punctate signals was only detectable in three cases. The results indicate an association of HR-HPV types with renal cell carcinoma. It is proposed that HPV infection in high-grade tumors might precede disease progression in a number of tumors, particularly of the papillary subtype.

Abstract
The primary underlying cause of cervical cancer is infection with one or more high-risk (HR) types of the human papilloma virus (HPV). Detection and typing of HPV have been commonly carried out by PCR-based assays, where HPV detection and typing are two separate procedures. Here, we present a multiplex PCR-based HPV typing assay that detects 20 HPV types (15 HR, 3 probably HR and 2 low risk) using type-specific primers and agarose gel electrophoresis. 46 cervical, urethral, and biopsy samples were analyzed by both Multiplex PCR and PGMY09/11 consensus PCR, and results were compared. 611 samples were further analyzed by Multiplex PCR, 282 were positive for HR HPV, and 101 showed multiple HR HPV infections. The relatively ease and economic accessibility of the method and its improved ability to detect high-risk HPV types in multiple HPV-infected samples make it an attractive option for HPV testing.

Abstract
OBJECTIVE Squamous Cell Carcinoma (SCC) is the most common malignancy of the oral cavity and Verrucous Carcinoma (VC) is its least invasive form with no metastasis potential. Leukoplakia (clinical term for hyperkeratosis and acanthosis with and without dysplasia) is the most common pre-malignant lesion of the oral cavity. Human Papilloma Virus (HPV) has been recognized as an etiologic factor for mentioned lesions. In this study the relationship between high risk types of this virus (HPV(HR)) with VC and Leukoplakia is investigated. MATERIALS AND METHOD Forty-one paraffin-embedded blocks including 21 VC, 20 leukoplakias in addition to 18 normal oral mucosal tissues as the control group were studied by Polymerase Chain Reaction (PCR) to detect HPV 16, 18, 31 and 33. RESULTS In three specimens of VCs (14.3%) HPV(HR) was detected. Each of these contained both HPV 16 and 18. All three positive specimens belonged to women older than 65 and were obtained from the vestibule of the mandible. Neither Leukoplakia nor normal mucosa showed HPV presence. No significant relationship between HPV and VC was found compared with the control group (p = 0.23). CONCLUSION This study did not show relationship between HPV and leukoplakia. Although no statistically significant relationship was found between HPV and VC, but considering sample size limitation for such uncommon cases, its presence in three cases of 14 makes more investigations to overcome the controversies necessary.

Abstract
A key issue in oral HPV infection is whether it can be associated with a genital HPV infection, or whether it can be considered as an independent event. This analysis evaluated the frequency and type-concordance of oral HPV infection in women with cervical HPV infection by means of: (i) a cross-sectional study on a sample (n=98) of Italian women; and (ii) a literature-based metanalysis, including the experimental study the subject of this Paper and nine other published studies (n=1017), which also examined the influence of oral sampling procedure (oral brushing vs oral rinse) and HIV status on oral HPV detection. The prevalence of oral HPV infection in the Italian study was 14.3% (95% CI: 7.4-21.2); the prevalence of type-concordance was 21.4% (95% CI: 0.0-43.6) and it was only marginally significant (P=0.05). The prevalence of oral HPV infection in the metanalysis was estimated as 18.1% (95% CI: 10.3-25.9); the prevalence of type-concordance was 27.0% (95% CI: 12.3-41.7), and it was statistically significant (P=0.002). The metanalysis also showed that the oral sampling procedure was not a determinant of HPV detection; however, HIV status increased the likelihood of oral HPV infection (HIV-positive vs negative: 27.2%; 95% CI: 22.1-32.2 vs 15.5%; 95% CI: 6.9-24.2) and type-concordance (HIV-positive vs negative: 46.8%; 95% CI: 34.7-58.9 vs 15.6%; 95% CI: 0.8-30.4). Oral HPV infection and type-concordance in women with cervical HPV infection are more prevalent than could be expected by chance; this finding is consistent with the notion of a degree of dependence of the oral site on the cervical site. Furthermore, oral HPV prevalence and type-concordance are influenced by immunity.

Abstract
Background Previous studies have either investigated the relationship of HPV with oral cancer or the prevalence of HPV on the oral cavity. The purpose of this investigation was to study the prevalence of HPV in oral cavity of women with oral sex practices and cervical lesions. Methods Forty six (46) non-smokers and non-alcoholic patients attended the "Clínica de Displasias" of "Ciudad Juarez" were sampled. This population had a CIN diagnosis sometime between the previous six months. On previous consent they filled out a questionnaire related to their oral sex practices. Afterwards one swab from cheeks and another from palate/gum were taken; PCR was used to determine generic HPV, HPV16 and HPV18. Results Seventy two percent (72%) of the patients stated to have oral sex practices regularly which all of them were positive to HPV either in oral mucus, palate/gum or both. The total of the given results showed that 35% had HPV16; among those distributed in 26% with regular oral sex practices and 9% stated as never practiced oral sex. An association was found between oral HPV16 positivity and progression to cervical CIN advanced lesions. On the other hand HPV18 was not detected. The frequency of HPV16 was higher in buccal mucosa (23%) versus palate/gum (16%). Conclusions This study suggests that buccal HPV16 infection is associated with CIN progression.

Abstract
Squamous cell carcinomas of the head and neck (HNSCC) are a frequent diagnosis in anatomic pathology practice. Tobacco use and heavy alcohol consumption are known risk factors for HNSCC but in other cases human papillomavirus (HPV) is linked to carcinogenesis. HPV proteins E6 and E7 promote oncogenesis by blocking the action of p53 and pRB, respectively. An absence of p53 mutations in addition to expression of p16 are part of the distinct molecular profile identified in the subset of HNSCCs because of HPV. Various methods are available for HPV detection but polymerase chain reaction and in situ hybridization techniques are commonly used. Both methods are amenable for testing formalin-fixed paraffin-embedded tissue that is a sample type readily available to the pathologist. HPV is detectable in approximately a quarter of all HNSCCs, and is particularly prevalent in the oropharynx in which the positivity rates approach 40%. A vast majority of HPV-related HNSCCs are owing to HPV type 16 with types 18, 31, and 33 accounting for almost all of the remaining cases. HPV-related HNSCCs are associated with better prognosis for both recurrence and survival. This group of tumors has also been shown to respond well to radiation treatment. As the clinical relevance of HPV in HNSCCs continues to emerge, anatomic pathologists are likely to receive increasing requests for testing. Herein, the authors review the biological and clinical aspects of HPV-associated HNSCC and review techniques for HPV detection.

Abstract
Head and neck malignancies are characterized by a multiphasic and multifactorial etiopathogenesis. Tobacco and alcohol consumption are the most common risk factors for head and neck malignancy. Other factors, including DNA viruses, especially human papilloma virus (HPV), may also play a role in the initiation or development of these lesions. The pathways of HPV transmission in the head and neck mucosal lesions include oral-genital contact, more than one sexual partner and perinatal transmission of HPV to the neonatal child. The increase in prevalence of HPV infection in these lesions may be due to wider acceptance of oral sex among teenagers and adults as this is perceived to be a form of safe sex. The prevalence of HPV in benign lesions as well as malignancies has been assessed by many techniques. Among these, the polymerase chain reaction is the most sensitive method. Review of literature reveals that HPV may be a risk factor for malignancies, but not in all cases. For confirmation of the role of HPV in head and neck squamous cell carcinoma, large population studies are necessary in an assortment of clinical settings. Prophylactic vaccination against high-risk HPV types eventually may prevent a significant number of cervical carcinomas. Of the two vaccines currently available, Gardasil (Merck & Co., Inc.) protects against HPV types 6, 11, 16 and 18, while the other vaccine, Cervarix (GlaxoSmithKline, Rixensart, Belgium) protects against HPV types 16 and 18 only. However, the HPV vaccine has, to the best of our knowledge, not been tried in head and neck carcinoma. The role of HPV in etiopathogenesis, prevalence in benign and malignant lesions of this area and vaccination strategies are briefly reviewed here.

Abstract
Head & Neck Cancer (HNC) represents the sixth most common malignancy worldwide and it is historically linked to well-known behavioural risk factors, i.e., tobacco smoking and/or the alcohol consumption. Recently, substantial evidence has been mounting that Human Papillomavirus (HPV) infection is playing an increasing important role in oral cancer. Because of the attention and clamor surrounding oral HPV infection and related cancers, as well as the use of HPV prophylactic vaccines, in this invited perspective the authors raise some questions and review some controversial issues on HPV infection and its role in HNC, with a particular focus on oral squamous cell carcinoma.

Abstract
Background Infection with high-risk human papillomavirus is an important factor associated with cervical cancer, and the distribution of HPV types varies greatly worldwide. Determination of type-specific HPV prevalence constitutes an important step towards the development of vaccines for the prevention of cervical cancer. Methods The human papillomavirus (HPV) genotypes in 190 cervical cancer specimens taken from the Sichuan province, the most populous province of Southwest China, were detected by a combination of MY09/11 consensus primers PCR (MY09/11 PCR), type-specific primers one-step PCR (One-step TS PCR) and E6/E7 gene type-specific primers nested PCR (Nested TS PCR). The prevalence and distribution of HPV in patients with cervical cancer, especially for HPV types 16, 18, 52, 58 and 59, suspected to be most common in certain parts of China, was investigated. Results The HPV infection rates detected by MY09/11 PCR, One-step TS PCR and Nested TS PCR were 159 (83.7%), 145 (76.3%) and 172 (90.5%), respectively. The overall HPV prevalence was 93.2% (177/190). The positive specimens for HPV16, 18, 52, 58 and 59 detected by One-step TS-PCR were 111 (58.4%), 14 (7.4%), 6 (3.2%), 13 (6.8%) and 4 (2.1%), respectively. By Nested TS-PCR analysis, the detection rates of HPV16, 52, 58 and 59 were increased to 140 (73.7%), 30 (15.8%), 37 (19.5%) and 25 (13.2%), while only 4 (2.1%) additional specimens were found to be infected with HPV18. Conclusion Our data demonstrate that, besides HPV 16, which was found to be the most prevalent type, HPV types 58, 52 and 59 are more prevalent than HPV18 in women with cervical cancer in the Sichuan area of China.

Abstract
PCR is an established technique providing rapid and highly productive amplification of specific DNA sequences. The demand for equally rapid, sensitive and objective methods to achieve detection of PCR products has led to the coupling of PCR with ELISA. PCR-ELISA involves direct incorporation of labeled nucleotides in amplicons during PCR-amplification, their hybridization to specific probes and hybrid capture-immunoassay in microtiter wells. PCR-ELISA is performed in 1 d and is very flexible, with the ability to process simultaneously up to 96 or 384 samples. This technique is potentially automatable and does not require expensive equipment, and thus can be fundamental in laboratories without access to a real-time PCR thermocycler. PCR-ELISA has mainly been used to detect infectious agents, including viruses, bacteria, protozoa and fungi. A PCR-ELISA protocol for the qualitative detection of papillomavirus genomes and simultaneous typing of different genotypes are detailed here as an example of the technique.

Abstract
The aim of this study was to evaluate the sensitivity, specificity, reliability and reproducibility of the EasyChip HPV blot for human papillomavirus (HPV) genotyping. Type-specific sensitivity and specificity for 39 types of HPV (HPV 6, 11, 16, 18, 26, 31, 32, 33, 35, 37, 39, 42, 43, 44, 45, 51, 52, 53, 54, 55, 56, 58, 59, 61, 62, 66, 67, 68, 69, 70, 72, 74, 82, CP8061, CP8304, L1AE5, MM4, MM7 and MM8) were examined. The operating environment, reliability, reproducibility and blot interpretation were assessed by a quality assurance system. Each batch experiment contained samples from 89 cervical specimens and 7 extrinsic controls. Caski, HeLa and Jurkat cells, male human blood cell DNA and sterile water were used to assess reliability. Furthermore, pairs of sibling controls were used to assess reproducibility. The overall sensitivity of HPV detection was 1-50 copies of HPV genome equivalent. There was no cross-reactivity with amplicons of other HPV genotypes. One hundred batch experiments demonstrated that the reliability was excellent. The intra-batch and inter-batch reproducibility was 98 and 97%, respectively. It was concluded that the EasyChip HPV blot is a highly sensitive, reliable and reproducible tool for detection and identification of HPV genotypes.

Abstract
BACKGROUND Restriction fragment length polymorphism (RFLP) methods for genotyping genital human papillomavirus (HPV) are considered labor consuming and constrained by the reduced set of restriction enzymes capable of detecting specific mutations. However, we think that these methods have not taken full advantage of the high diversity of the known restriction enzymes. OBJECTIVE We have set out to find the best restriction enzyme for HPV typing. STUDY DESIGN An extensive search for enzymes was carried out by combining statistical methods and database information. The search maximized the discrimination between high- and low-risk types by examining the sequence of the L1 gene flanked by primers MY09/11. Different electrophoretic resolutions and two variations of the RFLP method were considered. RESULTS HpyCH4V is the best enzyme for discriminating between risk types. Moreover, HpyCH4V generates different patterns for virtually all the HPV types. The typical pattern consists of two or three fragments, which facilitates typing in mixed infections. The typing of a set of clinical samples confirmed the expectations. CONCLUSIONS This result illustrates the possibilities of statistical methods to exploit the high diversity of restriction enzymes in order to classify samples in a pre-established hierarchy of types for which DNA sequences are known.

Abstract
Twenty-nine laboratories in 12 countries participated in a study to assess the performance of various human papillomavirus (HPV) detection assays through the use of a recombinant HPV DNA standard reagent panel. The panel was designed by a group of HPV experts, and samples were prepared and distributed by the World Health Organization International Laboratory for Standards and Biologicals in The Netherlands. Each panel consisted of 24 coded samples including a dilution series for HPV types 16 and 18, alone or in combination with five other high-risk (HR) HPV types including HPV types 31, 33, 35, 45, and 52, the low-risk HPV type 6, and a negative control. Qualitative assays were generally consistent across laboratories, and most invalid results reflected a lack of HPV test sensitivity. The combined data sets had a proficiency for HPV 16 of 62.5% (15/24) and for HPV 18 of 73.9% (17/23). HPV 31 was the least accurately detected by participating laboratories. Approximately half of participating laboratories failed to detect high concentrations of HPV 31 and, to a lesser extent, to detect HPV types 35, 52, and 6. The panel sample materials offer a source of renewable and reproducible material that could be used in the future development of international standard reagents for calibration of HPV DNA assays and kits.

Abstract
OBJECTIVE A newly introduced HPV detection technique in cervical lesion, the HPV DNA Chip test, contains 24 HPV probes and has the advantage of being able to detect 24 HPV types at once. We performed HPV DNA sequencing and compared the results with that of the HPV DNA Chip for evaluation of the accuracy of the DNA Chip test. METHODS The HPV DNA sequencing was performed in samples of 282 patients, where specific HPV type had been shown in HPV DNA Chip test. The sixteen cases where multiple HPV types had been found in HPV DNA Chip test were included in 282 cases. The sequencing was also performed in HPV-other type samples of 95 patients, where positive in HPV-PCR, but specific HPV type had not been found. RESULTS In 257 cases (91.1%) of 282 cases, the HPV types of the HPV DNA sequencing test were in agreement with types of the HPV DNA Chip. In 16 cases (5.7%), the sequencing types were different from the types of HPV DNA Chip. But, in 9 of 16 cases, types in HPV DNA sequencing were absent types in HPV DNA Chip test. The interpretation of HPV DNA sequencing was impossible in nine cases (3.2%). The HPV DNA sequencing test of 95 cases of HPV-other type showed that the sequencing types from 94 cases (98.9%) were absent types in HPV DNA Chip test. In sequencing test of HPV-other type, HPV-81 (20.0%), HPV-62 (14.7%), HPV-84 (13.7%), and HPV-61 (13.7%) were frequently detected. CONCLUSION HPV DNA Chip is an accurate method for detecting the 24 HPV genotypes.

Abstract
Bovine Papillomavirus type 2 (BPV-2) and chronic intoxication by bracken fern ingestion were associated with urinary bladder lesions and the clinical signs of enzootic haematuria in adult cattle. Clinically enzootic haematuria is characterized by intermittent haematuria followed by animal death. Enzootic haematuria causes considerable economical impact on extensive cattle breeding worldwide. The demonstration of BPV-2 participation in the etiology of bovine urinary bladder carcinoma by conventional virological methods is not easy and the integrity of epidemiological studies relies on methods that are sensitive and specific for BPV-2 detection and typing. A multiplex-PCR was evaluated for BPV-2 L1 gene and bovine mitochondrial genome ND5 gene (internal control) detection followed by a second round of BPV-2 amplification by a semi-nested PCR (SN-PCR). Six skin papilloma samples were used for PCR technique development. Twenty-two urinary bladder samples from symptomatic (n = 12) and asymptomatic (n = 10, control group) cows and 25 blood samples from cows grazed on enzootic haematuria-endemic (n = 14) and enzootic haematuria-free (n = 11, control group) geographical regions of Parana State, Brazil were analyzed. The SN-PCR detected BPV-2 in seven urinary bladder and 10 whole blood samples collected from cows with enzootic haematuria and in one urinary bladder and one whole blood samples of asymptomatic cows. The specificity of the amplicon was performed by restriction fragment length polymorphism and sequence analysis. The SN-PCR technique developed in this study will make possible the realization of diagnosis and comparative epidemiological studies to evaluate BPV-2 infection rates in cattle, and the association of this infection with bracken fern chronic intoxication in the etiology of enzootic haematuria and opens the possibility of ante mortem studies by lymphocytes analysis.

Abstract
We report a case with the inconsistency that the red blood cells lacked both A- and B-antigens while the serum showed reactivity with control B-red cells but not with A-red cells. A- and B-antigens were examined by serological blood typing and immunohistochemical staining, and DNA analyses were performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), DNA sequencing, and hot-stop PCR. A-antigens were demonstrable in the nail of the subject by serological study and immunostaining. DNA analyses showed that the nail retained a small amount of A-allele comparing to that of O-allele. Those genomic analyses of ABO genes were useful for demonstration of A allele in the nail of an individual with the absence of A antigen on red blood cells and the corresponding antibody in serum.

Abstract
BACKGROUND AND OBJECTIVES Human papillomaviruses (HPV) are the causal agent for the development of carcinomas in the cervix uteri and further pathological changes of the skin including mucosa, particularly warts, condylomas and dysplasias. Therefore, we investigated the efficacy of different consensus primers pairs for HPV detection by PCR using brushed samples from the oral cavity in comparison with samples from the cervix uteri. STUDY DESIGN In the present study, we used two well-established sets of PCR primers in different combinations for the detection of HPV DNA in 106 non-invasive brush biopsy samples of the oral mucosa and 56 samples from the cervix uteri. Direct sequencing of PCR products in all cases determined HPV genotype and specificity. RESULTS Overall, HPV was detected in 69 of 106 oral mucosa samples. HPV specific amplicons were obtained in 35.8% (N = 38) when using GP5+/6+ primers. The positivity rate was increased to 65.1% in a GP5+/6+ auto-nested PCR approach. In contrast, MY9/11 PCR and nested PCR with MY9/11 outer followed by GP5+/6+ inner primers yielded 2.2% and 16.1%, respectively. In gynaecological samples, PCR results were similar independent of the primer combination used. Thus, DNA quality and DNA content could be additional factors influencing the rate of positivity. CONCLUSION For oral mucosa samples, auto-nested GP5+/6+ PCR is in our hands the most suitable approach for epidemiological studies because of its high sensitivity, high reliability and reproducibility as well as its relatively simple laboratory procedure.

Abstract
Despite the high prevalence of cervical cancer and cervical neoplasias in South Africa, few studies have been performed in this region to establish which human papillomavirus (HPV) types are associated with the development of high-grade cervical intraepithelial neoplasia lesions and cervical cancer. To investigate these prevalence rates, punch biopsies were obtained from 56 women with cervical cancer and 141 women with histologically diagnosed cervical intraepithelial neoplasia 2 or 3 lesions. Nested polymerase chain reaction (PCR) using consensus degenerate PCR primers was performed for the detection of HPV DNA and HPV typing was done by restriction fragment length polymorphism. Forty-seven (94%) of the cervical cancer and 114 (88%) of the cervical intraepithelial neoplasia 2/3 biopsies were positive for HPV DNA. The prevalence rates of the HPV types detected in the cervical cancer biopsies were HPV 16 (82%), HPV 18, (10%), HPV 33 (10%), HPV 31 (2%), HPV 58 (2%), HPV 35 (2%), and HPV 59 (2%). The cervical intraepithelial neoplasia lesions contained HPV 16 (56.6%), HPV 33 (14%), HPV 31 (10.9%), HPV X (7%), HPV 52 (3.9), HPV 58 (3.1%), HPV 35 (2.3%), HPV 18 (1.6%), HPV 11 (0.8%). Five of the nine fragments that were not typed by the RFLP, designated HPV-X, were sequenced to give HPV6 (1/5), HPV 26 (2/5), HPV 68 (1/5), and candHPV 87 (1/5). HPV 58 was detected in one cervical cancer biopsy and four biopsies from cervical intraepithelial neoplasia grade 3 lesions and was shown to be a previously described variant [Williamson and Rybicki (1991) J. Med. Virol. 33:165-171]. In addition, a cervical intraepithelial neoplasia grade 2 lesion was shown to harbour HPV type HAN2294 (cand HPV 87). The results of this study indicate that cervical cancer and cervical intraepithelial neoplasia 2/3 are largely associated with HPV 16 infection in this group of South African women and, therefore, an effective HPV 16 based vaccine should prevent the development of cervical cancer in a large proportion of women from this region of South Africa.

Abstract
Despite the high prevalence of both human papillomavirus (HPV) infections and cervical cancer among Zimbabwean women, the ability to test for HPV infection of the uterine cervix is limited by a lack of an easy sample collection method that does not require gynecological examination. The presence of HPVs in urine and cervical swab samples collected from 43 women who presented with invasive cervical cancer was investigated. HPV detection was done by means of degenerate primers in a nested polymerase chain reaction (PCR). Typing of HPVs was done using restriction fragment length polymorphism (RFLP) analysis. HPV was identified and typed in 98% (42/43) of cervical swabs and 72% (31/43) of paired urine samples. HPV type 16 was the most common (25/42, 59%), followed by types: 33 (13/42, 31%), 18 (6/42, 14%), and 31 (1/42, 2%). Type-specific concordance between cervical and urine samples was high (22/28, 79%). Therefore, the HPV types identified in urine samples in most cases represent the same HPV type infecting the cervical epithelium. The results suggest that urine may be a practical sample for testing of HPV urogenital infection. Further research is required before the detection of HPV in urine can be applied in the routine cervical screening programs.

Abstract
O Papilomavírus humano (HPV) é um vírus ubíquo de DNA, epiteliotrópico, que tem a pele e as mucosas como principais sítios de infecção. Ultimamente, a sua associação com neoplasias benignas e malignas da cavidade oral, principalmente o carcinoma epidermóide, tem sido mais evidente. O seu achado comum em epitélio de mucosa oral normal, amplamente divulgado na literatura, não permite inferências mais precisas quanto ao seu papel na carcinogênese (se agente etiológico principal, coadjuvante ou simples habitante do epitélio de revestimento da mucosa oral). São mais de 100 tipos já identificados, dos quais 24 já foram localizados na cavidade oral. Desses, 4 são particularmente importantes, os tipos 6 e 11 (que estão envolvidos nas lesões benignas do epitélio oral) e 16 e 18 (comprovadamente carcinogênicos e possivelmente envolvidos na etiologia de determinados carcinomas epidermóides orais). A ação desses dois últimos tipos está principalmente associada às oncoproteínas E6 e E7 produzidas pelos mesmos. A E6 liga-se, seqüestra e degrada a p53, importante proteína supressora de tumor. A segunda liga-se e seqüestra a pRb, também supressora de tumor, facilitando a liberação de E2F. Apesar do aprimoramento das técnicas de detecção do HPV nas lesões de mucosa oral, o seu envolvimento direto com os carcinomas orais não foi ainda devidamente comprovado, todavia a sua ação sinérgica com outros carcinógenos químicos e físicos, tais como o fumo e o álcool, em determinados carcinomas epidermóides nos parece o caminho mais correto para explicar a ação do papilomavírus humano na carcinogênese oral.

Abstract
BACKGROUND Cervical cancer affects 1 in 2000 Zimbabwean women. We investigated the type-specific distribution of human papillomavirus (HPV) infection in Zimbabwean women with invasive cervical cancer. METHODS We conducted a descriptive study on 98 women with invasive cervical cancer. The methods used were a nested polymerase chain reaction (PCR) for amplification of HPV-DNA and restriction fragment length polymorphism (RFLP) to characterize the HPV types. RESULTS HPV-DNA was identified in 97% of the cases. HPV types 16, 33, 18 and 31 were identified in 61%, 39%, 18% and 4% of the patients, respectively. We typed one case each of HPV types 35 and 58. Multiple HPV infections were present in 24%. All patients (n = 3) with adenocarcinoma of the cervix were infected with the HPV. Patients infected with HPV-16 alone presented at a median age of 46 years while those infected with HPV-33 alone presented at 43 years. However, patients coinfected with both HPV-16 and HPV-33 were between 10 and 13 years older (median age of 56 years) than patients with either HPV-16 or HPV-33 as single infections. These differences were marginally significant (p = 0.08) or significant (p = 0.02), respectively. CONCLUSION We present the first prevalence data on HPV types in patients with cervical cancer in Zimbabwe and show that, provided appropriate techniques are employed, HPV infection can be identified in a majority of the patients. The distribution of HPV types should be taken into consideration in tailoring locally relevant vaccines against HPV.
