Ligase chain reaction (LCR)-based tests for the diagnosis of Chlamydia trachomatis and Neisseria gonorrhoeae infections in men and women attending a sexually transmitted disease clinic were evaluated. LCR testing of urethral swab and urine specimens from men and cervical swab and urine specimens from women was compared with culture of male urethral swabs(More)
Carbapenem resistance among Enterobacteriaceae is an emerging problem worldwide. Klebsiella pneumoniae carbapenemase (bla(KPC)) enzymes are among the most common beta-lactamases described. In this study, we report the development and validation of a real-time PCR (q-PCR) assay for the detection of bla(KPC) genes using TaqMan chemistry. The q-PCR(More)
Population HIV-1 sequencing is currently the method of choice for the identification and follow-up of HIV-1 antiretroviral drug resistance. It has limited sensitivity and results in a consensus sequence showing the most prevalent nucleotide per position. Moreover concomitant sequencing and interpretation of the results for several samples together is(More)
The emergence of oseltamivir-resistant influenza A pandemic (H1N1) 2009 virus highlights the need for rapid oseltamivir resistance screening. We report the development and validation of high-throughput real-time reverse transcriptase PCR assays for the detection of the H275Y substitution in the neuraminidase 1 gene that can be accomplished in 3 to 4 h.
We investigated coinfection of human bocavirus (HBoV) and other respiratory viruses in hospitalized children by real-time PCR. A high rate (69.2%) of adenovirus infection was found among children infected with HBoV. Such high rates of HboV-adenovirus coinfection have not been previously reported, underscoring the need to investigate the contribution of HBoV(More)
Differences in baseline polymorphisms between subtypes may result in development of diverse mutational pathways during antiretroviral treatment. We compared drug resistance in patients with human immunodeficiency virus subtype C (referred to herein as "subtype-C-infected patients") versus subtype-B-infected patients following protease inhibitor (PI)(More)
BACKGROUND Expanded access to HIV therapy in the developing world raises serious concerns regarding the potential emergence and transmission of drug-resistant HIV strains. Although HIV drug resistance surveillance is recommended to track transmitted HIV drug resistance among newly infected individuals, the financial constraints in resource-limited countries(More)
BACKGROUND Centralized data collection and analytic tools facilitate tracing HIV transmission trends at the patient-population level with increasing resolution, complementing behavioral studies while avoiding sampling biases. By several measures, the rate of HIV infection among men who have sex with men (MSM) in Israel increased in the past several years(More)
Rapid detection of drug-resistant bacteria in clinical samples plays an instrumental role in patients' infection management and in implementing effective infection control policies. In the study described in this report, we validated a multiplex TaqMan real-time quantitative PCR (qPCR) assay for the detection of bla(KPC) genes and the human RNase P gene in(More)
