Phenolic content and antibacterial activity of extracts of Hamelia patens obtained by different extraction methods

Braz. j. microbiol; 49 (3), 2018
Abstract Hamelia patens, is a plant traditionally used to treat a variety of conditions among the Huastec people of Mexico. The objective of this study is to characterize the phenolic content and critically examine the antimicrobial activity of leaf extracts H. patens, obtained by maceration, Soxhlet and...

Primary antibiotic resistance and its relationship with cagA and vacA genes in Helicobacter pylori isolates from Algerian patients

Braz. j. microbiol; 49 (3), 2018
Abstract The epidemiology of Helicobacter pylori resistance to antibiotics is poorly documented in Africa and especially in Algeria. The aim of our study was to determine the antibiotic resistance rates, as well as its possible relationship with VacA and CagA virulence markers of isolates from Algerian p...

Study of pandrug and heavy metal resistance among E. coli from anthropogenically influenced Delhi stretch of river Yamuna

Braz. j. microbiol; 49 (3), 2018
Abstract Escalating burden of antibiotic resistance that has reached new heights present a grave concern to mankind. As the problem is no longer confined to clinics, we hereby report identification of a pandrug resistant Escherichia coli isolate from heavily polluted Delhi stretch of river Yamuna, India....

Antibacterial activity of fractions and isolates of Maytenus guianensis Klotzsch ex Reissek (Celastraceae) Chichuá Amazon

Abstract INTRODUCTION This aim of this study was to evaluate the antibacterial activity of fractions and isolates of Maytenus guianensis, a plant species used in Amazonian folk medicine. METHODS A disk diffusion technique was used to investigate the antibacterial potential. RESULTS The hexanic frac...

Primera comunicación en Chile de la detección del gen mcr-1 en un aislado clínico de Escherichia coli resistente a colistín

Rev. chil. infectol; 35 (4), 2018
Recently it was described the plasmidial gene mcr-1 associated with colistin resistance. We screened by PCR and sequencing for gene mcr-1 in thirteen clinical isolates resistant to colistin. We observed amplification in one E. coli. To our knowledge, this is the first report of the presence of mcr-1 gene...

Fatal case of donor-derived colistin-resistant carbapenemase-producing Klebsiella pneumoniae transmission in cardiac transplantation

Braz. j. infect. dis; 22 (3), 2018
ABSTRACT Herein we report a fatal case of donor-derived transmission of XDR-resistant carbapenemase-producing Klebsiella pneumoniae (KPC-Kp) in cardiac transplantation. A 59-year-old male patient with non-obstructive hypertrophic cardiomyopathy underwent heart transplantation. On day 5 post-operation, bl...

A study of community-acquired Mycoplasma pneumoniae in Yantai, China

Colomb. med; 49 (2), 2018
Abstract Introduction: Community-acquired pneumonia (CAP) is a global disease responsible for a large number of deaths, with significant economic impact. As diagnostic tools have increased in sensitivity, understanding of the etiology of CAP has begun to change. Mycoplasma pneumoniae is one of the majo...

Meropenem Efflux in Pseudomonas aeruginosa at a Tertiary Care Hospital in Jamaica

West Indian med. j; 67 (2), 2018
ABSTRACT Objective: Several mechanisms account for carbapenem resistance in Pseudomonas (P) aeruginosa which is an emerging problem at a tertiary care hospital (TCH) in Jamaica. The observed pattern of carbapenem resistance that results from efflux mechanisms is unique because it is specific to meropene...
