Assessment of screening practices in a subacute clinical setting following introduction of Trichomonas vaginalis nucleic acid amplification testing.

Objective: Trichomonas vaginalis analyte-specific reagent is a highly sensitive assay for T vaginalis detection. We report how this diagnostic innovation influenced the sexually transmitted infection ordering practice patterns of 20 subacute-care clinicians.

Methods: T vaginalis, Neisseria gonorrhoeae, and/or Chlamydia trachomatis screening data were audited on female swab submissions when only wet mount testing was available for detection of T vaginalis (2004-2007) and when T vaginalis detection options included analyte-specific reagent and wet mount (2008-2010).

Screening of male patients for Trichomonas vaginalis with transcription-mediated amplification in a community with a high prevalence of sexually transmitted infection.

Trichomonas vaginalis infection in males has been largely uncharacterized. Past reports indicated increased susceptibility to other sexually transmitted infection (STI) agents such as human immunodeficiency virus and Neisseria gonorrhoeae with concurrent T. vaginalis infection.

Female epidemiology of transcription-mediated amplification-based Trichomonas vaginalis detection in a metropolitan setting with a high prevalence of sexually transmitted infection.

Recent literature has reported increased accuracy of Trichomonas vaginalis transcription-mediated amplification (TMA)-based analyte-specific reagent (ASR) testing in female populations. A retrospective investigation assessed 7,277 female first-void urine, cervical, or vaginal specimens submitted from a high-prevalence sexually transmitted infection (STI) community to characterize prevalence of disease etiologies. The most common STI phenotype reflected detection of solely T.

Three-year history of transcription-mediated amplification-based Trichomonas vaginalis analyte-specific reagent testing in a subacute care patient population.

A total of 7,899 specimens submitted for live clinical Trichomonas vaginalis analyte-specific reagent (ASR) screening from 2008 to 2010 were audited on the basis of patient gender, specimen source, molecular Neisseria gonorrhoeae and Chlamydia trachomatis results, and relative light unit (RLU) data yielded by T. vaginalis ASR. Only 1.

Cost-effective modification of a commercial PCR assay for detection of methicillin-resistant or -susceptible Staphylococcus aureus in positive blood cultures.

Real-time detection of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) in cases of clinical bacteremia may promote appropriate antimicrobial therapy and infection control. Expense inherent to molecular diagnostics may prevent laboratories from utilizing real-time PCR for this purpose.
