Comparison of direct fluorescent antibody, acridine orange, wet mount, and culture for detection of Trichomonas vaginalis in women attending a public sexually transmitted diseases clinic.

Abstract

To define the performance characteristics of two newer tests for Trichomonas vaginalis (TV), the authors compared direct fluorescent antibody (DFA) (mixed monoclonal antibody, Integrated Diagnostics, Inc, Berkeley, CA) and acridine orange (AO) tests to standard wet mount (WM) preparations and culture (modified Diamond medium) of vaginal wash specimens in consecutively examined women presenting to a public sexually transmitted diseases (STD) clinic. Cultures for Neisseria gonorrhoeae (GC), Chlamydia trachomatis (CT), and yeast were also performed on all patients. Of 104 women, 59 (57%) were infected with one or more pathogens. Trichomonas vaginalis was detected by WM and/or culture in 38 (37%) women and was the most prevalent infection. Of the 38 patients with TV, 95% were detected by culture, 83% by DFA, 66% by AO, and 66% by WM. An additional patient was DFA positive but negative for TV by all other methods. The sensitivity of DFA was superior to AO and WM in women with TV infection alone (96% compared to 67% and 53%, respectively). It was comparable to AO and WM in women with multiple infections (67% compared to 53% and 73%). Even in the presence of other pathogens, DFA appears to be a reasonable alternative to culture for de...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
