BACKGROUND Knowledge of the causative organism(s) in bacterial rhinosinusitis has become the cornerstone of adequate medical and surgical management. Little uniformity and data exist for the best method of obtaining sinus cultures. Most otolaryngologists tend to use the nasal swab for obtaining transnasal middle meatal cultures. A prospective study was carried out to compare the effectiveness o...
OBJECTIVE Detection of meningococcal carriers is key to understanding the epidemiology of Neisseria meningitidis, yet no gold standard has been established. Here, we directly compare two methods for collecting pharyngeal swabs to identify meningococcal carriers. METHODS We conducted cross-sectional surveys of schoolchildren at multiple sites in Africa to compare swabbing the posterior pharynx...
OBJECTIVE To evaluate the frequency and antimicrobial susceptibility pattern of Acinetobacter species isolated from pus and pus swab specimens at a tertiary care setting. STUDY DESIGN Cross-sectional observational study. PLACE AND DURATION OF STUDY Department of Microbiology, Armed Forces Institute of Pathology, Rawalpindi, from July 2008 to July 2012. METHODOLOGY Data regarding positive ...
BACKGROUND In general practice, infectious conjunctivitis is a common and mostly (64%) self-limiting disorder. In case of an aberrant course or severe symptoms, a general practitioner may take a culture. Direct inoculation is considered the reference standard, but usually a swab is sent to a laboratory. OBJECTIVES To compare the diagnostic performance of the swab, transported by surface mail ...
PURPOSE To assess the prevalence of fluoroquinolone resistance among patients undergoing transrectal ultrasound (TRUS)-guided prostate biopsy and the impact of rectal swab culture-directed antibiotic prophylaxis on postbiopsy infectious complications. MATERIALS AND METHODS We prospectively analyzed all patients undergoing TRUS-guided prostate biopsy from April 2013 to February 2015. Antibioti...
BACKGROUND There is paucity of information regarding the epidemiology of Escherichia coli O157: H7 in developing countries. In this study, we investigated the occurrence of E. coli O157: H7 associated with beef cattle at processing plants and at retail shops in Ethiopia. METHODS Various samples were collected from beef cattle at slaughter/processing plants, carcass at retail shops and humans ...
We evaluated the cost-effectiveness of using buccal swab brushes in comparison with blood samples for obtaining DNA for large epidemiological studies of the elderly population. The data reported here are from the third phase of the Integral Study of Depression among the Elderly in Mexico City's Mexican Institute of Social Security, conducted in 2007. The total cost of the two procedures was det...
This study was done to assess the specificity and sensitivity of the DNA amplification assays of ligase chain reaction (LCR) and polymerase chain reaction (PCR) on urine specimens to detect Chlamydia trachomatis infections in both male and female patients seen at a sexually transmitted diseases (STD) clinic in Singapore, compared with other diagnostic methods currently in use. A total of 100 pa...
The cellular quality of the endocervical swab specimen used for the detection of Chlamydia trachomatis may dramatically impact the sensitivity of the diagnostic assay used. An evaluation of the adequacy of 319 endocervical swab specimens from women attending two inner-city sexually transmitted disease and family planning clinics, as well as five high school-based family planning clinics, was pe...
