Enterobacter cloacae and E. aerogenes have been increasingly reported as important opportunistic pathogens. In this study, a high prevalence of multi-drug resistant isolates from Brazil, harboring several β-lactamase encoding genes was found. Several virulence were observed in aerogenes, contrasting with the which presented none.
Campylobacter coli and jejuni are two of the most common causative agents food-borne gastroenteritis in numerous countries worldwide. In Brazil, campylobacteriosis is underdiagnosed under-reported, few studies have molecularly characterized spp. this country. The current study genotyped 63 C. strains isolated from humans (n = 12), animals 21), food 10) environment 20) between 1995 2011 Brazil. were using pulsed-field gel electrophoresis (PFGE), sequencing short variable region (SVR) flaA...
This study aimed to identify antimicrobial resistance genotypes in 63 Campylobacter coli strains isolated from humans (12), animals (21), the environment (20), and food (10) Brazil using whole genome sequencing (WGS) tools, comparing them with results obtained by susceptibility testing (AST) against some important antimicrobials clinical use.Phenotypic profiles were determined minimal inhibitory concentrations disk diffusion technique. The prediction of genes was performed ABRicate v.0.8...
Aims: The objectives of this study were to genotype a total 48 Campylobacter jejuni and 39 coli strains isolated in Brazil from 1995 2016 by multilocus sequence typing (MLST) determine their resistance profile. presence or points mutation the related genes was verified. Results: By MLST, C. typed into 36 STs 27 STs. A 70.8% 35.9% resistant at least one antimicrobial tested. tet(O) gene detected 43.7% 12.8% coli. ermB not presented 23S rRNA gene. Besides, 58.3% substitution T86I quinolone...
Resistance of Salmonella Dublin strains to quinolones and tetracycline has been increasing worldwide. Studies regarding the genotypic resistance traits this serovar isolated in Brazil are scarce. This study aims examine genetic characteristics Brazil, which associated with quinolone tetracycline. The minimum inhibitory concentrations (MICs) nalidixic acid, ciprofloxacin, 10 sensitive 21 resistant were determined using Etest.® mutation profiles gyrA, gyrB, parC, parE genes accessed by...
This study compared the capacity of strains Salmonella enterica serovars Enteritidis and Dublin isolated in Brazil to invade epithelial cells, be internalized by survive within macrophages, stimulate cytokine release vitro.Both infected 75 73% Caco-2 (human) MDBK (bovine) cells respectively. S. (i) were at respective rates 79·6 65·0% (P ≤ 0·05) U937 70·4 66·9% HD11 (chicken) macrophages; (ii) multiplied 3·2- 2·7-fold 1·9- 1·1-fold Seventy per cent 10 stimulated IL-8 production, while 70%...
Whole-genome sequencing analyses have provided important data and information on the repertoire of resistance genes in several bacterial species. This study examined to what extent antimicrobial found a set whole-genome-sequenced Salmonella Enteritidis strains from Brazil correlated with phenotypic possibly related these genes. The genotypic studied were compared publicly available isolated other countries. profiles accessed NCBI Pathogen Detection website, determined by disk diffusion...
Campylobacter spp. have been reported as one of the most frequent causes acute gastroenteritis in humans worldwide. Here, we report 17 draft genome sequences C. coli strains isolated from animal and food sources Brazil. These data will improve our understanding this species
Introduction. Salmonella 1,4, [5],12:i:- strains with different antimicrobial resistance profiles have been associated foodborne disease outbreaks in several countries. In Brazil, S . was identified as one of the most prevalent serovars São Paulo State during 2004–2020. Gap Statement. However, few studies characterized this serovar Brazil. Aim. This study aimed to determine isolated from sources Southeast Brazil and compare their genetic diversity. Methodology. We analysed 113 humans ( n...
Campylobacter spp. have been reported as a common cause of gastroenteritis in humans many countries. However, Brazil there is insufficient data to estimate the impact public health. In light importance this foodborne pathogen, aim study was perform comparative analyses on 80 Brazilian coli genomes isolated from human feces, animals, environment, and food. Methods include Average Nucleotide Identity (ANI), Gegenees, genomic plasticity, presence pathogenicity, resistance, metabolic islands....
