TLDR
The supplemental information presented in this document is intended for use with the antimicrobial susceptibility testing procedures published in the following Clinical and Laboratory Standards Institute (CLSI)–approved standards.Abstract:
The supplemental information presented in this document is intended for use with the antimicrobial susceptibility testing procedures published in the following Clinical and Laboratory Standards Institute (CLSI)–approved standards: M02-A12—Performance Standards for Antimicrobial Disk Susceptibility Tests; Approved Standard—Twelfth Edition; M07-A10—Methods for Dilution Antimicrobial Susceptibility Tests for Bacteria That Grow Aerobically; Approved Standard—Tenth Edition; and M11-A8—Methods for Antimicrobial Susceptibility Testing of Anaerobic Bacteria; Approved Standard— Eighth Edition. The standards contain information about both disk (M02) and dilution (M07 and M11) test procedures for aerobic and anaerobic bacteria. Clinicians depend heavily on information from the microbiology laboratory for treatment of their seriously ill patients. The clinical importance of antimicrobial susceptibility test results demands that these tests be performed under optimal conditions and that laboratories have the capability to provide results for the newest antimicrobial agents. The tabular information presented here represents the most current information for drug selection, interpretation, and QC using the procedures standardized in the most current editions of M02, M07, and M11. Users should replace the tables published earlier with these new tables. (Changes in the tables since the previous edition appear in boldface type.) Clinical and Laboratory Standards Institute (CLSI). Performance Standards for Antimicrobial Susceptibility Testing. 26th ed. CLSI supplement M100S (ISBN 1-56238-923-8 [Print]; ISBN 1-56238924-6 [Electronic]). Clinical and Laboratory Standards Institute, 950 West Valley Road, Suite 2500, Wayne, Pennsylvania 19087 USA, 2016. The data in the interpretive tables in this supplement are valid only if the methodologies in M02-A12—Performance Standards for Antimicrobial Disk Susceptibility Tests; Approved Standard—Twelfth Edition; M07-A10—Methods for Dilution Antimicrobial Susceptibility Tests for Bacteria That Grow Aerobically; Approved Standard—Tenth Edition; and M11-A8—Methods for Antimicrobial Susceptibility Testing of Anaerobic Bacteria; Approved Standard— Eighth Edition are followed.read more

Journal ArticleDOI
Antimicrobial activity of six pomegranate (Punica granatum L.) varieties and their relation to some of their pomological and phytonutrient characteristics.
TL;DR: It has been observed that the pomegranate aril extracts had antimicrobial effect on all microorganisms, giving inhibition zones ranging in size from 13 to 26 mm, and the results obtained appeared to confirm the antimicrobial potential of the Punica granatum varieties.
Journal ArticleDOI
Silent dissemination of colistin-resistant Escherichia coli in South America could contribute to the global spread of the mcr-1 gene.

Fernandes,Quézia Moura,Luciana Sartori,Ketrin Cristina da Silva,Marcos Pv Cunha,Fernanda Esposito,Ralf Lopes,Luciana Kazue Otutumi,Daniela Dib Gonçalves,Milena Dropa,Maria Helena Matté,Daniel Fm Monte,Mariza Landgraf,Gabriela Rodrigues Francisco,Maria Fc Bueno,Doroti de Oliveira Garcia,Terezinha Knöbl,Andrea Micke Moreno,Nilton Lincopan +18 more
TL;DR: Evidence that mcr-1-positive Escherichia coli has been emerging in South America since at least 2012 is presented, supporting a previous report on the possible acquisition of mcr -1-harbouring E. coli by European travellers visiting Latin American countries.

A Canadian National Surveillance Study of Urinary Tract Isolates from Outpatients: Comparison of the Activities of Trimethoprim-Sulfamethoxazole, Ampicillin, Mecillinam, Nitrofurantoin, and Ciprofloxacin
George G. Zhanel,James A. Karlowsky,Godfrey K. M. Harding,A. Carrie,Tony Mazzulli,Don E. Low,Daryl J. Hoban +6 more
TL;DR: Ampicillin, trimethoprim-sulfamethoxazole, mecillinam, nitrofurantoin, and ciprofloxacin mean resistance rates for 2,000 urinary tract isolates collected from outpatients across Canada in 1998 were 41.1, 19.2, 14.7, 5.0, and 1.8%, respectively as discussed by the authors.

Emergence of carbapenem-non-susceptible extended-spectrum β-lactamase-producing Klebsiella pneumoniae isolates at the university hospital of Tübingen, Germany
Sabine Gröbner,Dirk Linke,Wolfgang Schütz,Claudia Fladerer,Johannes Madlung,Ingo B. Autenrieth,Wolfgang Witte,Yvonne Pfeifer +7 more
TL;DR: A systematic exploration of intestinal colonization with ESBL isolates should be reconsidered, at least for haemato-oncological departments from where four of the five carbapenem-non-susceptible ESBL isolate originated.

Blue-carba, an easy biochemical test for detection of diverse carbapenemase producers directly from bacterial cultures.
João Pires,A. Novais,Luísa Peixe +2 more
TL;DR: Quick, simple, and reliable methods are needed for laboratory detection of carbapenemases that are widely disseminated among Gram-negative bacteria, in order to improve the detection and surveillance of these clinically relevant bacteria in an epidemiological context.
