Community-Associated Extended-Spectrum β-Lactamase–Producing Escherichia coli Infection in the United States
Yohei Doi,Yoon Soo Park,Yoon Soo Park,Jesabel I. Rivera,Jennifer M. Adams-Haduch,Ameet Hingwe,Emilia Mia Sordillo,James S. Lewis,Wanita J. Howard,Laura Johnson,Bruce Polsky,James H. Jorgensen,Sandra S. Richter,Kathleen A. Shutt,David L. Paterson +14 more
TL;DR: A substantial portion of community-onset, ESBL-producing E. coli infections now occur among patients without discernible healthcare-associated risk factors in the United States, which has implications for the empiric management ofcommunity-associated infection when involvement of E. bacteria is suspected.
Journal ArticleDOI
Multicenter Evaluation of BBL CHROMagar MRSA Medium for Direct Detection of Methicillin-Resistant Staphylococcus aureus from Surveillance Cultures of the Anterior Nares
Diane Flayhart,Janet F. Hindler,David A. Bruckner,Geraldine S. Hall,Rabin K. Shrestha,Sherilynn Vogel,Sandra S. Richter,Wanita J. Howard,Rhonda Walther,Karen C. Carroll +9 more
TL;DR: In this study, C-MRSA was superior to TSA II for recovery of MRSA from surveillance specimens obtained from the anterior nares and was comparable to conventional, rapid, and molecular susceptibility methods for the identification ofMRSA isolates.
Journal ArticleDOI
Evaluation of the Bruker Biotyper and Vitek MS Matrix-Assisted Laser Desorption Ionization–Time of Flight Mass Spectrometry Systems for Identification of Nonfermenting Gram-Negative Bacilli Isolated from Cultures from Cystic Fibrosis Patients
Daniel C. Marko,Ryan T. Saffert,Scott A. Cunningham,Jay M. Hyman,John Walsh,Sophie S Arbefeville,Wanita J. Howard,Jon Pruessner,Nedal Safwat,Franklin R. Cockerill,Aaron D. Bossler,Robin Patel,Sandra S. Richter +12 more
TL;DR: The Bruker Biotyper and Vitek MS matrix-assisted laser desorption ionization–time of flight (MALDI-TOF) mass spectrometry (MS) instruments were evaluated for the identification of nonfermenting Gram-negative bacilli (NFGNB) by a blinded comparison to conventional biochemical or molecular methods.
Journal ArticleDOI
Prevalence and Genetic Relatedness of Methicillin-Susceptible Staphylococcus aureus Isolates Detected by the Xpert MRSA Nasal Assay
Sophie S Arbefeville,Kunyan Zhang,J. Kroeger,Wanita J. Howard,Daniel J. Diekema,Sandra S. Richter +5 more
TL;DR: Methicillin-susceptible Staphylococcus aureus isolates lacking mecA yet testing positive on the Xpert MRSA assay were recovered from culture for 7.7% of 248 Xpert-positive nasal samples, suggesting these “false-positive” Xpert results may be attributed to staphylitiscal cassette chromosome (SCC) elements without themecA gene.
Journal ArticleDOI
Multicenter Evaluation of the BD Phoenix Automated Microbiology System for Antimicrobial Susceptibility Testing of Streptococcus Species
Sandra S. Richter,Wanita J. Howard,Melvin P. Weinstein,David A. Bruckner,Janet F. Hindler,Michael A. Saubolle,Gary V. Doern +6 more
TL;DR: The Phoenix system provided reliable and rapid AST results for most of the organism-antimicrobial agent combinations tested, and showed the following trends.
