In 899 women attending a genitourinary medicine clinic Chlamydia trachomatis was tested for using both a Cytobrush and a conventional swab. In 425 cases, the Cytobrush was used for concurrent cytology and chlamydia sampling. Both methods were equally effective in the detection of chlamydia, and, in addition, the Cytobrush gave a higher yield of inclusion bodies per sample. The use of the same i...

abstract   background: wound infection is a frequent and severe complication in burn patients accounting for a high number of mortalities. there are some reports comparing swab and biopsy cultures of wounds of various etiologies or chronic wounds.   objectives: the aim of the study was to evaluate burn wound infection by different bacteriologic methods of surface swab and tissue biopsy culture ...

In recent years, cleaning validation has achieved a position of increasing in the pharmaceutical industry. It provides assurance to the cleaning procedure that ensures equipment is consistently cleaned from the product, detergent and microbial residues to an acceptable level to avoid cross-contamination and adulteration of drug product with other active ingredients. The aim of this study was to...

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...

Medical staff working in a nasopharyngeal swab sampling cabin are exposed to higher exposure risk of COVID-19. In this study, computational fluid dynamics (CFD) used evaluate the medical Chinese customs under four different ventilation strategies, i.e., multiple supply fans (MSFV), exhaust (MEFV), single fan and outer windows closed (SEFV), opened (SEFV-W). The impact physical partitions on is ...

and Implications Submitting tissue samples via mail may present challenges to practitioners with respect to public health, public perception, and regulatory restrictions. Considering these challenges of tissue sampling, the objective of this pilot study was to evaluate alternative sampling techniques for the detection and characterization of Escherichia coli (E. coli) in field cases of diarrhea...

BACKGROUND Chile has broad variations in weather, economics and population from the far desert north (Region 1) to the cold, icy south (Region 12). A home-based self-collected vaginal sampling was nested in the 2003 Chilean population-based health survey in order to explore the possibility of a type-specific geographical variation for human papillomavirus METHODS The population was a national...

Current recommendations suggest that negative rapid Streptococcus pyogenes antigen tests be backed up with a culture, reflecting evidence that culture may have a higher sensitivity and also that testing of a second swab may yield a different (i.e., a positive) result because of variation in sample size or distribution. If the latter is common, the sensitivities of current antigen detection test...
