Intereactions between doripenem and clavulanate — Application of minimal inhibitory concentration analysis and cytometry flow for bactericidal studies

Background: In view of the current low efficacy of bacterial infection treatment the common trend towards searching for antibiotic systems exhibiting synergistic action is well justified. Among carbapenem analogues a particularly interesting option is provided by combinations of clavulanic acid with mero...

Draft genome sequence of Chryseobacterium limigenitum SUR2T (LMG 28734T) isolated from dehydrated sludge

Braz. j. microbiol; 49 (1), 2018
ABSTRACT The type strain SUR2 of the novel species Chryseobacterium limigenitum was isolated from a dehydrated sludge of the municipal sewage treatment plant in Dogoše near Maribor in Slovenia. The draft genome, with 60 contigs, 4,697,725 bp, 34.4% of G+C content, was obtained using the Illumina HiS...

Removal and killing of multispecies endodontic biofilms by N-acetylcysteine

Braz. j. microbiol; 49 (1), 2018
ABSTRACT Removal of bacterial biofilm from the root canal system is essential for the management of endodontic disease. Here we evaluated the antibacterial effect of N-acetylcysteine (NAC), a potent antioxidant and mucolytic agent, against mature multispecies endodontic biofilms consisting of Actinomyces...

Impacto das mudanças da microbiologia na peritonite bacteriana espontânea em três diferentes períodos ao longo de 17 anos

Arq. gastroenterol; 55 (1), 2018
ABSTRACT BACKGROUND: Spontaneous bacterial peritonitis is a serious complication in cirrhotic patients, and changes in the microbiological characteristics reported in the last years are impacting the choice of antibiotic used for treatment. OBJECTIVE: The aim of the present study is to evaluate the ch...

Combined effect of bacteriocin produced by Lactobacillus plantarum ST8SH and vancomycin, propolis or EDTA for controlling biofilm development by Listeria monocytogenes

Rev. argent. microbiol; 50 (1), 2018
The Listeria monocytogenes strains selected in the present study exhibited similar behavior in biofilm formation, independently of the tested conditions (bacteriocin from L. plantarum ST8SH, vancomycin, propolis (a natural antimicrobial product) and EDTA (chelating agent)), individual or in associations....

Sensibilidad a fosfomicina en Escherichia coli productoras de betalactamasas de espectro extendido

RESUMEN Las infecciones urinarias son causadas mayormente por Escherichia coli (E. coli), el uso indiscriminado de antibióticos ha originado un aumento de infecciones por cepas productoras de betalactamasas de espectro extendido (BLEE). Con el objetivo de determinar la sensibilidad a fosfomicina se real...

Detection of the mecA gene and identification of Staphylococcus directly from blood culture bottles by multiplex polymerase chain reaction

Braz. j. infect. dis; 22 (2), 2018
ABSTRACT Introduction: Staphylococcus spp. - both S. aureus, including methicillin-resistant strains (MRSA) and coagulase negative staphylococci (CoNS) - are relevant agents of healthcare-associated infections. Therefore, the rapid recognition of MRSA and methicillin-resistant CoNS from blood stream inf...
