Journal ArticleDOI
Multiplex PCR detection of vanA, vanB, vanC-1, and vanC-2/3 genes in enterococci.
TL;DR: Multiplex PCR-restriction fragment length polymorphism appears to be a useful and convenient method for rapidly detecting and discriminating genotypes for vancomycin-resistant Enterococcus spp.
Journal ArticleDOI
An Outbreak of Invasive Group A Streptococcal Disease Associated With High Carriage Rates of the Invasive Clone Among School-aged Children
Franklin R. Cockerill,Kristine L. MacDonald,Rodney L. Thompson,Fred Roberson,Peggy C. Kohner,John M. Besser-Wiek,Janice M. Manahan,James M. Musser,Patrick M. Schlievert,James Talbot,Benjamin J. Frankfort,James M. Steckelberg,Walter R. Wilson,Michael T. Osterholm +13 more
TL;DR: A single clone of group A Streptococcus was responsible for 7 cases of invasive streptococcal disease during an outbreak in Minnesota and for a significant number of pharyngitis cases that also occurred during the outbreak.
Journal ArticleDOI
Determination of 16S rRNA Sequences of Enterococci and Application to Species Identification of Nonmotile Enterococcus gallinarum Isolates
Robin Patel,Kerryl E. Piper,Mark S. Rouse,James M. Steckelberg,J. R. Uhl,Peggy C. Kohner,Marlene K. Hopkins,Franklin R. Cockerill,Bruce C. Kline +8 more
TL;DR: 16S rRNA sequences were utilized to confirm the species identification of two nonmotile E. gallinarum isolates which had been previously phenotypically identified as E. faecium and E. solitarius.
Journal ArticleDOI
Comparison of agar dilution, broth microdilution, disk diffusion, E-test, and BACTEC radiometric methods for antimicrobial susceptibility testing of clinical isolates of the Nocardia asteroides complex.
TL;DR: The BACTEC radiometric method appeared to be the best for determining the in vitro susceptibilities of members of the N. asteroides complex to a panel of nine antimicrobial agents, however, none of the test methods, including the BactEC method, accurately predicted the ampicillin resistance of theN.
Journal ArticleDOI
Comparison of a Novel, Rapid Chromogenic Biochemical Assay, the Carba NP Test, with the Modified Hodge Test for Detection of Carbapenemase-Producing Gram-Negative Bacilli
Shawn Vasoo,Scott A. Cunningham,Peggy C. Kohner,Patricia J. Simner,Jayawant N. Mandrekar,Karen Lolans,Mary K. Hayden,Robin Patel +7 more
TL;DR: This study compared carbapenemase detection among 271 Gram-negative bacilli using a novel chromogenic rapid test—the Carba NP test—and the modified Hodge test and found CNP was more specific and faster than MHT.
