Samples for forensic DNA analysis are often collected from a wide variety of objects using cotton or nylon tipped swabs. Testing has shown that significant quantities of DNA are retained on the swab, however, and subsequently lost. When processing evidentiary samples, the recovery of the maximum amount of available DNA is critical, potentially dictating whether a usable profile can be derived f...

Salmonella enterica strains isolated in Okinawa between 1995 and 2005 were analyzed with respect to their serovars and antimicrobial susceptibility, and pulsed-field gel electrophoresis (PFGE) was used to examine their digestion patterns. A total of 1,071 isolates, including 610 from humans, 358 from animal rectal swabs and 103 from meat obtained at grocery stores, were examined. The first 3 mo...

Title: Genotyping of Streptococcus agalactiae (group B streptococci) isolated from vaginal and rectal swabs of women at 35-37 weeks of pregnancy

This paper analyses the results of diagnostic swabs taken from children seen at a pertussis contact clinic between December, 1950, and April, 1952. Two new diagnostic techniques entailing contaminating swabs by cough, which were developed during this period, yielded a high percentage of positive cultures. A preliminary communication on one of these new techniques was published when the initial ...

A recent switch to a less expensive swab transport product initiated by our purchasing department provided a reference point for this report. Copan swabs (Copan Diagnostics, Inc., Corona, Calif.) were replaced by Starswab swabs (Starplex Scientific, Etobicoke, Ontario, Canada). Both products employ a sponge saturated with liquid Stuart’s medium. The Starplex product appeared visually to vary in...

BACKGROUND High-risk human papillomavirus (hrHPV) causes virtually all cervical cancers. Trans masculine (TM) people (those assigned female at birth who identify with a gender other than female) have low uptake of conventional cervical cancer screening. Self-collected hrHPV DNA testing has high levels of acceptability among cisgender (non-transgender) females and may support increased cervical ...

BACKGROUND The microbiome of built environment surfaces is impacted by the presence of humans. In this study, we tested the hypothesis that analysis of surface swabs from clinic toilet/bathroom yields results correlated with sexually transmitted infection (STI) notifications from corresponding human populations. We extended a previously reported study in which surfaces in toilet/bathroom facili...

The ability to directly release 5 aerobic and 5 anaerobic bacterial strains from 3 swab transport systems was evaluated by a time zero roll-plate method. The Copan ESwab (Copan Diagnostics, Murrieta, CA), a new nylon-flocked swab with Amies liquid medium, yielded greater organism release and recovered approximately 10-fold more microorganisms than the Becton Dickinson (Sparks, MD) CultureSwab M...

A burn patient was infected with Acinetobacter baumannii on transfer to the hospital after a terrorist attack. Two patients experienced cross-infection. Environmental swab samples were negative for A. baumannii. Six months later, the bacteria reemerged in 6 patients. Environmental swab samples obtained at this time were inoculated into a minimal mineral broth, and culture results showed widespr...
