First characterization of K. pneumoniae ST11 clinical isolates harboring blaKPC-3 in Latin America

Rev. argent. microbiol; 52 (3), 2020
Abstract Antimicrobial resistance due to carbapenemase production in Enterobacteriaceaeclinical isolates is a global threat. Klebsiella pneumoniae harboring the blaKPCgene is one ofthe major concerns in hospital settings in Latin America.The aim of this study was to characterize the antibiotic resistance...

Macrolide-lincosamide-streptogramin B resistance phenotypes and their associated genotypes in Staphylococcus aureus isolates from a tertiary level public hospital of Uruguay

Rev. argent. microbiol; 52 (3), 2020
Abstract This study was undertaken to investígate the resistance phenotypes to macrolide-lincosamide-streptogramin B (MLSb) antibiotics and their associated genotypes in isolates of Staphylococcus aureus. We analyzed one hundred, consecutive, non-duplicate isolates (methicillin-susceptible MSSA, n = 53 ...

Caracterización clínica, epidemiológica y microbiológica de bacteriemias producidas por enterobacterias resistentes a carbapenems en un hospital universitario de Córdoba, Argentina

Rev. chil. infectol; 37 (4), 2020
Resumen Introducción: Las enterobacterias son una causa principal de infecciones del torrente sanguíneo y su resistencia antimicrobiana se encuentra en aumento. Esto lleva a un incremento de la morbilidad-mortalidad y de los costos en la salud pública. Las enterobacterias resistentes a carbapenems re...

Evaluation of zinc-oxide nanocoating on the characteristics and antibacterial behavior of nickel-titanium alloy

ABSTRACT Objective: To investigate the effect of ZnO nanocoating on mechanical properties of NiTi orthodontic wires and antibacterial activity. Methods: 0.016 x 0.022-in NiTi orthodontic wires were coated with ZnO nanoparticles using an electrochemical deposition method with three electrodes system in...

Activity of ceftolozane-tazobactam and comparators against gram-negative bacilli: Results from the study for monitoring antimicrobial resistance trends (SMART - Brazil; 2016-2017)

Braz. j. infect. dis; 24 (4), 2020
Abstract Multi-drug resistant Gram-negative bacilli (GNB) have been reported as cause of serious hospital-acquired infections worldwide. The aim of this study was to investigate the in vitro activity of ceftolozane-tazobactam compared to other agents against GNB isolated from patients admitted to Brazili...

Identifying gram-positive cocci in dermatoscopes and smartphone adapters using MALDI-TOF MS: a cross-sectional study

An. bras. dermatol; 95 (3), 2020
Abstract Background: The increasingly frequent use of dermoscopy makes us think about the possibility of transfer of microorganisms, through the dermatoscope, between doctor and patients. Objectives: To identify the most frequent gram-positive cocci in dermatoscopes and smartphone adapters, as well as ...

Chemical characterization, antimicrobial and antioxidant activity of sugar-apple (Annona squamosa L. ) pulp extract

Rev. chil. nutr; 47 (2), 2020
Synthetic preservatives are widely present in processed foods, but most of them have carcinogenic potential, requiring the development of new natural alternatives such as fruit extracts, for microbial control. The objective of the study was to evaluate the chemical characterization, antioxidant, and anti...

Coagulase-negative staphylococci: a 20-year study on the antimicrobial resistance profile of blood culture isolates from a teaching hospital

Braz. j. infect. dis; 24 (2), 2020
ABSTRACT The increasing rates of nosocomial infection associated with coagulase-negative staphylococci (CoNS) were the rationale for this study, aiming to categorize oxacillin-resistant CoNS species recovered from blood culture specimens of inpatients at the UNESP Hospital das Clínicas in Botucatu, Braz...
