Salmonella Heidelberg is frequently found in poultry and products associated with antimicrobial resistance strains infections mortality humans. Whole-genome sequencing used to monitor understand epidemiological factors related resistance. This study aimed characterize the phenotypic sequence whole genome of isolated from Brazil. Fourteen broiler chicken carcasses portions Brazil between 2013 2019 were this study. Genus confirmation was performed by polymerase chain reaction. The disk...
ABSTRACT: Enteropathogenic Escherichia coli (EPEC) and Shigatoxigenic E. (STEC) strains are among the major pathotypes found in poultry their products, which capable of causing human enteric infections. Colistin has been claimed drug choice against diseases caused by multidrug-resistant Gram-negative bacteria (MDRGN) humans. The mcr-1 gene was first plasmidial that described to be responsible for colistin resistance also detected birds products. Our study aimed detect enteropathogenic order...
Avian mycoplasmosis is a disease of significant economic impact, potentially leading to restrictions on the international trade poultry products. Mycoplasma synoviae (MS) and gallisepticum (MG) are well-established as pathogenic, while gallinaceum (Mgc) considered commensal. Nevertheless, latter can exacerbate clinical conditions in cases co-infections with other pathogens. Due slow growth rates MS MG, they susceptible being outpaced by fast growing mycoplasmas, thereby complicating...
The draft genome sequence of Campylobacter jejuni (Cj26) was analysed to investigate genetic mechanisms antimicrobial resistance, virulence-associated genes, and phylogenetic context. Antimicrobial resistance assessed by agar dilution disk diffusion. Cj26 sequenced using NovaSeq 6000 technology. assembled annotated. Resistance genes chromosomal mutations were the Center for Genomic Epidemiology services, multilocus type, SVR-flaA, porA determined. virulome determined Virulence Factor...
1. This study evaluated the minimal inhibitory concentration (MIC) of ciprofloxacin and presence plasmid-mediated quinolone resistance (PMQR) mechanisms in 97 nontyphoidal Salmonella spp. isolated from broilers carcases three different regions Brazil. The mutations determination (QRDRS) was investigated ciprofloxacin-resistant strain by DNA sequencing.2. Most (85.6%) had intermediate to only one isolate resistant. MIC breakpoints ranged ≤0.03 1 µg/ml 67.0% strains a 0.25 (n=65). Thirteen...
Enteropatogenic Escherichia coli (EPEC) and shigatoxigenic E. (STEC), are generally poultry product isolate can cause serious human infections. Many strains may become resistant to various antimicrobials, which hinder the treatment of bacterial diseases. Organic farming seeks avoid selection frequency antimicrobial-resistant bacteria. This study aims verify resistance EPEC STEC from organic conventional (industrial) broiler isolates antimicrobials. All were submitted disk diffusion test with...
Broiler chickens and derived products are a key source of Shiga toxin-producing Escherichia coli (STEC) in humans. This pathotype is responsible for causing severe episodes diarrhea, which can progress to systemic complications. A rapid accurate diagnosis the disease, early treatment infection with antimicrobials, prevent it worsening. However, multidrug-resistant strains have potentially negative implications success. In this context, aim present study was isolate identify STEC from broiler...
