Studies show COPAN products ideal for pertussis specimen transport
The two studies, published in the Journal for Clinical Microbiology, detailed UTM's versatility as a transport product. Both studies said UTM is a cross-platform medium proven to be good for use with viruses, including bordetella.
One of the studies showed that real-time PCR positivity rates for specimens collected both by rayon swabs in Amies gel with charcoal and flocked swabs in UTMs were comparable.
COPAN products have been featured in past reports as ideal transport and collection systems for pertussis.
Researchers presented a study at the American Society for Microbiology's general meeting in May of 2011 showing the effectiveness of COPAN's ESwab product.
"ESwab maintains sufficient B. pertussis and B. parapertussis viability to permit detection in culture and preserves cell and DNA integrity for DFA and PCR detection after 96 hours of refrigerated storage," the study said.
The Centers for Disease Control and Prevention reported 9,964 cases of pertussis, also known as whooping cough, between January and June of this year in the U.S. That number reflects a 24 percent increase over the same period last year.
California has seen a particularly high number of whooping cough cases. The U.S. Department of Health and Human services called the outbreak a problem of epidemic proportions.
