Abstract Background Antimicrobial Photodynamic therapy (A-PDT) has been used to treat infections. Currently, microbial inactivation data is reported presenting survival fraction averages and standard errors as discrete points instead of a continuous curve of inactivation kinetics. Standardization of this approach would allow clinical protocols to be introduced globally, instead of the piecemeal situation which currently applies. Methods To this end, we used a power-law function to fit inactivati...

Multidrug-resistant (MDR) Salmonella enterica has been deemed a high-priority pathogen by the World Health Organization. Two hundred and sixty-four Salmonella enterica isolates recovered over a 16-year period (2000 to 2016) from the poultry and swine production chains, in Brazil, were investigated by whole-genome sequencing (WGS). Most international lineages belonging to 28 serovars, including, S. enterica serovars S. Schwarzengrund ST96, S. Typhimurium ST19, S. Minnesota ST548, S. Infantis ST32...

Abstract Objectives Klebsiella pneumoniae sequence type 307 (ST307) has emerged as a new high-risk clone worldwide. The aim of this study was to report the draft genome sequence of a multidrug-resistant CTX-M-15-positive K. pneumoniae strain causing urinary tract infection in a companion animal in Brazil. Methods Whole-genome sequencing was performed on an Illumina NextSeq platform and the genome was de novo assembled using SPAdes. Data analysis was performed using online tools from the Center f...

Arcobacter butzleri is an emerging foodborne zoonotic pathogen that has been isolated from environmental water sources. This pathogen establishes in vitro endosymbiotic relationships with Acanthamoeba castellanii, a free-living amoeba found in environmental matrices such as soil and water. The principal aim of this study was to analyse the transcriptional pattern of flagellar (flaA-flaB-flgH-motA) and other putative virulence genes (ciaB-cadF-mviN-pldA) of A. butzleri during its interaction with...

Abstract Objectives TEM-52 extended-spectrum β-lactamases (ESBLs) have been detected in members of the family Enterobacteriaceae isolated from human and non-human reservoirs, mainly in European countries. We hereby report the first draft genome of a multidrug-resistant TEM-52b-positive Escherichia coli isolated from a companion animal in France. Methods Whole genomic DNA from E. coli 39590 was extracted and sequenced using an Illumina NextSeq platform. De novo genome assembly was performed using...

Abstract We analyze the evolutionary dynamics of ninety carbapenem-resistant Acinetobacter baumannii (CRAB) isolates collected between 1990 and 2015 in Chile. CRAB were identified at first in an isolate collected in 2005, which harbored the ISAba1-blaOXA-69 arrangement. Later, OXA-58- and OXA-23-producing A. baumannii strains emerged in 2007 and 2009, respectively. This phenomenon was associated with variations in the epidemiology of OXA-type carbapenemases, linked to nosocomial lineages belongi...

Abstract Background International clones of multidrug-resistant Escherichia coli have been a leading cause of human and animal infections worldwide. Microbial inactivation by blue light has been proposed as an effective treatment for superficial infections and surface contamination. Aim To evaluate the inactivation efficacy of blue light irradiation against high-risk multidrug-resistant strains of E. coli. Methods Blue LED light (λ = 410 nm) was used to inactivate in vitro suspensions of colisti...

The class D β-lactamase OXA-143 has been described as an efficient penicillinase, oxacillinase, and carbapenemase. The D224A variant, known as OXA-231, was described in 2012 as exhibiting less activity toward imipenem and increased oxacillinase activity. Additionally, the P227S mutation was reported as a case of convergent evolution for homologous enzymes. To investigate the impact of both mutations (D224A and P227S), we describe in this paper a deep investigation of the enzymatic activities of ...
