There are more than 40 human papillomaviruses (HPVs) belonging to the alpha genus that cause sexually transmitted infections; these infections are among the most frequent and can lead to condylomas and anogenital intra-epithelial neoplasia. At least 18 of these viruses are causative agents of anogenital carcinomas. We evaluated the performance of a resequencing microarray for the detection and ...

We compared the performance characteristics of a standardized direct sequencing method (TRUGENE HCV 5'NC; Visible Genetics Inc., Toronto, Ontario, Canada) and a reverse hybridization line probe assay (INNO-LiPA HCV II; Bayer Corp., Tarrytown, N.Y.) for genotyping of hepatitis C virus (HCV). Both methods are based on detection of sequence heterogeneity in the 5' noncoding (5'NC) region. Concorda...

BACKGROUND Researchers often group various HPV types into composite measures based on vaccine subtypes, oncogenic potential, or phylogenetic position. Composite prevalence estimates based on PCR genotyping assay results have been calculated to assess HPV infection burden and to monitor HPV vaccine effectiveness. While prevention and intervention strategies can be made based on these prevalence ...

Hepatitis C virus (HCV) isolates from a cohort of 315 patients from the Benelux countries (Belgium, The Netherlands, Luxembourg) were genotyped by means of reverse hybridization Inno-LiPA (line probe assay). Genotypes 1a, 1b, 2a, 2b, 3a, 4a and 5a were detected. From the cohort, isolates representing all types and those showing an aberrant LiPA pattern were further analysed by sequencing parts ...

A polymerase chain reaction-restriction fragment mass polymorphism (PCR-RFMP) assay protocol using PGMY09/11 primers for the detection and identification of human papillomavirus (HPV) has recently been developed. The present study evaluated the analytical sensitivity and clinical utility of HPV genotyping employing PCR-RFMP as compared to direct sequencing. Serial dilutions of cloned HPV DNA we...

The first detected case of genotype 4 of the hepatitis C virus (HCV) in Salvador, Bahia, is described. RT-PCR tests were used to detect HCV-RNA, and LIPA was used for genotyping. Genotype 4 responds poorly to treatment, and it is therefore important to actively search for people who have been in contact with it.

BACKGROUND Persistent infection with high risk human papillomavirus (hrHPV) is strongly associated with cervical cancer. Normal cervical cells may also harbor hrHPV, and detection of early hrHPV infection may minimize risk of cervical cancer development. This study aimed to compare two commercial HPV genotyping assays that may affordable for early screening in a limited-resource setting in Band...

The United Kingdom Health Protection Agency Mycobacterium Reference Unit offers a national "Fastrack" molecular service for detecting Mycobacterium tuberculosis complex (MTBC) and rifampin resistance by using the INNO-LiPA Rif.TB assay. We analyzed the service in a routine, nontrial context of 1,997 primary clinical specimens, including 658 nonrespiratory specimens. The overall adjusted concord...

BACKGROUND To assess the long-term effectiveness and safety of adefovir (ADV) plus lamivudine (LMV) in LMV-resistant (R) kidney transplants with chronic hepatitis B, 11 such patients were treated with add-on ADV. METHODS Serum alanine aminotransferase, renal function and serum hepatitis B virus (HBV) DNA levels were assessed every 3 months; ADV mutations were searched for by INNO-LiPA HBV DR ...

BACKGROUND There is limited understanding of the health economic implications of cervical screening with human papillomavirus (HPV)-16/18 genotyping. OBJECTIVE The aim of this study was to evaluate the cost effectiveness of cervical cancer primary screening with a HPV-16/18 genotyping test which simultaneously detects 12 other high-risk HPV types. METHODS A Markov cohort model compared four...
