The aim of the present study was the examination of the boot swab sampling technique for the collection of environmental material in order to identify Mycobacterium avium ssp. paratuberculosis (MAP)-infected herds. Eight dairy herds were included into the study. Four of them had a well-known history of MAP-infection from a herd surveillance programme conducted since 2006. Cows in these herds we...
BACKGROUND Due to frequent infections in cystic fibrosis (CF) patients, repeated respiratory cultures are obtained to inform treatment. When patients are unable to expectorate sputum, clinicians obtain throat swabs as a surrogate for lower respiratory cultures. There is no clear data in adult subjects demonstrating the adequacy of throat swabs as a surrogate for sputum or BAL. Our study was des...
BACKGROUND AND OBJECTIVES Methicillin-resistant Staphylococcus aureus (MRSA) is one of major pathogens in patients with chronic suppurative otitis media (CSOM). In addition to intrinsic MRSA infection of the mastoid air cell system, nasal colonization of MRSA, a known predictor of postoperative surgical site infection, may pose increased risk of postoperative complications. The purpose of this ...
The virologic test results of 415 patients with severe acute respiratory syndrome (SARS) were examined. The peak detection rate for SARS-associated coronavirus occurred at week 2 after illness onset for respiratory specimens, at weeks 2 to 3 for stool or rectal swab specimens, and at week 4 for urine specimens. The latest stool sample that was positive by reverse transcription-polymerase chain ...
BACKGROUND Recent evidence suggests that endoscopically obtained cultures from the middle meatus give comparable results to antral puncture for acute sinusitis. The best method for obtaining middle meatal cultures remains somewhat controversial because it has been theorized that specimens obtained with a swab are contaminated easily. This study compares endoscopic culture results from two diffe...
PURPOSE Measurement of intravaginal pH provides a reasonable assessment of vaginal health but is fraught with the potential for several sampling errors. The purposes of the study were to determine the variability of self-sampled vaginal pH among women using an inexpensive swab-based pH test compared with a clinician-obtained specimen, and variability of vaginal pH within 3 regions of the normal...
background trichomonas vaginalis infection is the most prevalent sexually transmitted disease in the world. it causes vaginitis, urethritis and preterm birth. it has been associated with nongonococcal urethritis in men. in this study, a polymerase chain reaction (pcr) targeting the beta-tubulin genes of t. vaginalis was developed for the detection of the organism in both vaginal swab and urine ...
