A Comparison of Dacron versus Flocked Nylon Swabs for Anal Cytology Specimen Collection

A comparison of dacron versus Flocked nylon swabs for anal cytology specimen collection.

OBJECTIVES We compared the performance of commonly used Dacron versus flocked nylon swabs for anal cytology. STUDY DESIGN From 23 HIV-positive men screened at Kaiser Permanente San Francisco (San Francisco, Calif., USA), 2 anal specimens were collected, 1 with each swab in random order, and placed into liquid cytology medium. Specimens were tested for cellularity by quantifying a genomic DNA ...

Mycoplasma hyopneumoniae detection in nylon-flocked and rayon-bud swabs.

The objective of this study was to compare the absorption and M. hyopneumoniae detection by real-time PCR using nylon-flocked and rayon-bud swabs. Results of this study showed that absorption and detection of M. hyopneumoniae were significantly higher in nylon-flocked swabs with Ct differences only ranging from 0.5 to 1.7.

[Usefulness of flocked swabs for sample collection of adenovirus].

Post-coital vaginal sampling with nylon flocked swabs improves DNA typing.

In the examination of sexual assault cases, DNA typing of vaginal samples mostly occurs after differential DNA extraction. Notwithstanding the differential extraction method, the DNA profiles from the seminal fraction often show the male alleles at low-level in combination with female alleles. This unfavorable ratio male to female DNA is due to a limited amount of sperm cells and an overwhelmin...

Better detection of Staphylococcus aureus nasal carriage by use of nylon flocked swabs.

Flocked swabs (Copan) were compared to rayon swabs (Copan) for the nasal detection of Staphylococcus aureus in 90 healthy volunteers sampled sequentially during a 5-week period. The use of flocked swabs improved the number of nasal carriers (P = 0.026), the number of positive specimens (P = 0.01), and the quantity of bacteria in positive samples (P = 0.004).
