Media Influence on Bystander Intervention for Health Protective Norms: The Integrative Model of Behavioral Prediction Perspective.

Drawing upon the Integrative Model of Behavioral Prediction (IM) and the Bystander Intervention Model, this study investigates the impact of media health information on individuals' intentions to address violations of health norms, specifically noncompliance with mask-wearing during the COVID-19 pandemic. Our survey results (=1,426) indicate a positive correlation between seeking health information from the media and the intention to confront norm violators regarding mask-wearing. This correlation is mediated through three intermediary pathways: attitudes, normative beliefs, and perceived behavioral control.

CG258 Klebsiella pneumoniae isolates without β-lactam resistance at the onset of the carbapenem-resistant Enterobacteriaceae epidemic in New York City.

Objectives: To examine the epidemiology of β-lactam resistance in 'clonal group 258' (CG258), a successful KPC clonal group, over 14 years.

Methods: Isolates were collected from 1999 to 2013 for a study of antibiotic resistance in Enterobacteriaceae in New York City; 515 bloodstream isolates had antibiotic susceptibility data available and 436 were available for a CG258 PCR assay. The 56 resulting CG258 isolates were characterized by MLST, capsular type and ESBL and KPC carriage.

Coidentification of and in a Clinical Enterobacter cloacae Isolate from China.

We describe the first report of a clinical colistin-resistant ST84 isolate coharboring (previously named ) and from a patient in China. The -harboring IncX3 plasmid and the novel -harboring ColE plasmid were completely sequenced. Although this isolate showed a high level of resistance to colistin, plasmid transformation, gene subcloning, susceptibility testing, and lipid A matrix-assisted laser desorption ionization mass spectrometry analysis indicated that itself does not confer resistance to colistin.
