Conjunctivitis is a very common presentation to general practitioners and general paediatricians. The investigation of conjunctivitis can be a significant cost to microbiology laboratories due to the high volume of samples that can be submitted, particularly from patients in the community. The key issue is to send eye swabs in clinical situations where it can make a difference to management, an...
Transmission of methicillin-resistant Staphylococcus aureus (MRSA) from animals to humans is of great concern due to the implications for human health and the health care system. The objective was to investigate the frequency and duration of MRSA carriage in human volunteers after a short-term exposure in a swine farm. The experimental study included 34 human volunteers staying 1 h in a MRSA-po...
Depletion of swabs and viral transport medium during epidemics may prompt the use of unvalidated alternatives. Swabs collected and transported dry or in saline were compared to commercially available swab/medium combinations for PCR detection of influenza, enterovirus, herpes simplex virus, and adenovirus. Each was detected at an ambient temperature (22°C) and 4°C for 7 days. Detection of influ...
This study compared a kit containing a nasopharyngeal nylon flocked swab and a tube with a liquid universal transport medium (UTM) with a kit containing a plastic-shafted rayon-budded swab with a sponge reservoir of viral transport medium for the molecular detection of influenza viruses in children. Respiratory samples were collected from 314 children aged <5 years with influenza-like illness (...
Non-invasive specimens for dengue diagnosis may be preferable where venous blood is difficult to collect and/or process, such as community-based or remote settings or when sampling from young children. We evaluated the performance of oral swabs and dried blood spots (DBS), compared with plasma, in diagnosing acute dengue and screening for past dengue virus (DENV) exposure. DENV-specific immunog...
The environment is implicated as a source of healthcare-associated infections (HAIs) and there is a need for evidence-based approaches to environmental sampling to assess cleanliness and improve infection prevention and control. We assessed, in vitro, different approaches to sampling the environment for meticillin-resistant Staphylococcus aureus (MRSA). In a laboratory-based investigation, the ...
This study investigates the quantitative bacterial recovery of Methicillin-resistant Staphylococcus aureus (MRSA) in nasal screenings by utilizing dry or moistened swabs within an in vivo and an in vitro experimental setting. 135 nasal MRSA carriers were each swabbed in one nostril with a dry and in the other one with a moistened rayon swab. Quantitative bacterial recovery was measured by stand...
BACKGROUND The present study is an evaluation of a self-collected urine dip (SCUD) swab as an alternative sampling method for the detection of Chlamydia trachomatis (CT) in urine samples that conforms to postal service regulations in Australia. METHODS Sixty urine samples, previously identified as CT positive were used to prepare SCUD swabs in vitro. In addition, replicate SCUD swabs were pre...
Rectal swabs and stool specimens were compared for the detection of Campylobacter fetus subsp. jejuni in marmosets. Rectal swabs were superior to stool specimens for detection of Campylobacter fetus subsp. jejuni (P = 0.016). Preliminary human data are also presented.
BACKGROUND The need for the timely collection of diagnostic biosamples during symptomatic episodes represents a major obstacle to large-scale studies on acute respiratory infection (ARI) epidemiology. This may be circumvented by having the participants collect their own nasal swabs. We compared self- and staff-collected swabs in terms of swabbing quality and detection of viral respiratory patho...
