In this study, we demonstrate a portable cellphone-based microphotometer, which combines a microbial viability reagent, a polydimethylsiloxane (PDMS) multiwell array, simple optics, and an iPhone, to allow rapid quantitative assessment of the antimicrobial resistance profiles of pathogens. With the portable system, antimicrobial resistance profiling and antimicrobial susceptibility testing (AST...

Tetracycline class agents vary widely in their activity against emerging important antimicrobial-resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) and Acinetobacter spp. Also, published susceptibility breakpoints are discordant between the Clinical and Laboratory Standards Institute (CLSI), the European Committee on Antimicrobial Susceptibility Testing (EUCAST), and...

OBJECTIVES Antimicrobial resistance of Helicobacter pylori endangers the successful eradication of the bacteria. The aim of this prospective surveillance study (ResiNet) is to continuously keep antimicrobial resistance of H. pylori in Germany under surveillance and to identify risk factors for its development. METHODS From July 2001 until December 2012, we tested the antimicrobial susceptibil...
