Abstract Antimicrobial resistance (AMR) is a major threat to global health. Understanding the emergence, evolution, and transmission of individual antibiotic genes (ARGs) essential develop sustainable strategies combatting this threat. Here, we use metagenomic sequencing analyse ARGs in 757 sewage samples from 243 cities 101 countries, collected 2016 2019. We find regional patterns resistomes, these differ between subsets corresponding drug classes are partly driven by taxonomic variation....
OBJECTIVE: To describe the prevalence and antimicrobial resistance of Salmonella spp. in frozen chicken carcasses at retail from 15 Brazilian cities. METHODS: A descriptive study data National Program for Monitoring Prevalence Bacterial Resistance Chicken (PREBAF) was conducted September 2004 to July 2006. The program collected state capitals Brazil five geographic regions country. Standardized methodologies were used isolate Salmonellaspp. identify serotypes. minimal inhibitory...
Whole genome sequencing (WGS) has been used as a powerful technology for molecular epidemiology, surveillance, identification of species and serotype, the sources outbreaks, among other purposes. In Brazil, there is relatively few epidemiological data on Salmonella. this study, 90 Salmonella Typhimurium strains had their sequenced to uncover diversity isolated from humans food, between 1983 2013, different geographic regions in Brazil based single nucleotide polymorphism (SNP) analysis. A...
Salmonella is one of the major causative agents foodborne infections. Salmonellosis becomes more dangerous when strains resistant to several antibiotics are found in food, especially chicken, primary transmission vehicles this pathogen for humans. The present study aimed estimate occurrence chicken carcasses from state Mato Grosso, Brazil, as well determine antibiotic resistance profile and genotypic characteristic multi-drug (MDR) isolates. During a 15-month period, 01/2014 05/2015, 850...
Background/Objectives: Salmonella Saintpaul (SSa) is increasingly linked to foodborne outbreaks in Brazil and globally. Despite its rising public health significance, epidemiology, genomic diversity, pathogenic potential remain underexplored. This study addresses these gaps through a comprehensive global analysis of SSa population dynamics, outbreak patterns, genetic structures, along with an in-depth phenotypic characterization strain PP_BR059, isolated from hospitalized patient Ceará,...
A resistência antimicrobiana (RAM) é uma ameaça à saúde da humanidade, mesmo depois de quase um século progresso do uso compostos antimicrobianos. Estudos estimam que em 2050 as mortes oriundas RAM ultrapassarão a marca 10 milhões. interação homem, animal, vegetal e meio ambiente, o antibióticos aos antimicrobianos são estudadas sob abordagem única. Este artigo teve como objetivo, determinar prevalência enterobactérias, os padrões susceptibilidade antimicrobiana, virulência amostras isoladas...
Out of the twenty-four samples shrimp and fish muscle used for this study, twelve were collected near a large marine sewer waste disposal, 3 km off coast Fortaleza (Brazil) isolation E. coli. Other at Mucuripe fresh market (Fortaleza, Brazil) Staphylococcus aureus. Ethanol, water acetone-diluted extracts guava papaya leaf sprouts tested on bacteria in order to verify their microbicidal potential. The coli strains trials rated LT positive. (Carica Linn) showed no activity while sprout...
Objectives: To determine the occurrence of class 1 and 2 integrons antimicrobial resistance genes among sulphonamide-resistant Shigella strains isolated in Brazil during 1999–2003.
Reports about acquired resistance to colistin in different bacteria species are increasing, including E. coli of animal origin, but reports wild S. enterica serotypes from swine not found the literature. Results obtained with one hundred and twenty-six strains diseased twenty-four carrier showed a frequency 6.3% 21% colistin-resistant strains, respectively. When comparing disk diffusion test agar dilution evaluate it was confirmed that is recommended as described previously. The MIC 90 50...
Salmonella spp. is an important zoonotic pathogen related to foodborne diseases. Despite that quinolones/fluoroquinolones are considered a relevant therapeutic strategy against resistant isolates, the increase in antimicrobial resistance additional difficulty controlling bacterial infections caused by Thus, acquisition of quinolones worrisome scientific community along with possibility transmission through plasmids. This study investigated prevalence plasmid-mediated quinolone (PMQR) and its...
Non-typhoidal salmonellosis is an important zoonotic disease caused by Salmonella enterica. The aim of this study was to investigate the prevalence plasmid-mediated quinolone resistance in spp. and its association with fluoroquinolone susceptibility Brazil. A total 129 NTS isolates (samples from human origin, food animal environmental, animal) grouped as (n = 62) 67) were evaluated between 2009 2013. These investigated through serotyping, antimicrobial testing, presence (PMQR) genes (qnr,...
Abstract Salmonella Dublin is a cattle-associated serovar sporadically causing disease in humans. S. strains isolated Brazil and other countries were analyzed to determine their phylogenetic relationships, the presence of genes, plasmids, genomic regions related virulence antimicrobial resistance genes repertoire, using WGS analyses. Illumina was used sequence genome 112 from humans (n = 82) animals 30) between 1983 2016. Furthermore, 87 analyzed. WGSNP analysis revealed three different...
Introduction This research aimed to identify and quantify potentially pathogenic Vibrio from different cultivations of bivalve shellfish in the State Santa Catarina, Brazil, water regions South Bay, as well correlate incidence these microorganisms with physicochemical parameters marine waters. Methods Between October 2008 March 2009, 60 oyster seawater samples were collected six mollusk cultivation, submitted for counts. Results Twenty-nine (48.3%) revealed be contaminated one or more...
The prevalence of Salmonella spp. was investigated in 109 wild birds poached the illegal wildlife trade Rio de Janeiro; most them are passerines from Thraupidae family and three Psittacidae. One strain ser. Typhimurium two strains Panama were isolated passerine species all showed resistance to multiple antimicrobial drugs, like ampicillin, ceftriaxone, ceftiofur, tetracycline, gentamicin, nalidixic acid, ciprofloxacin, enrofloxacin. PFGE 100% similarity among a Temminck's seedeater...
The illegal wildlife trade may increase the risk of infectious disease transmission, and it not only cause outbreaks in humans but also threaten livestock, native wild populations, ecosystems' health. Bird species act as carriers transmission enteric pathogens. However, epidemiological studies on zoonotic bacteria birds are rare Brazil. From March 2011 to 2012, we investigated frequency Enterobacteriaceae cloacal swab samples from 109 passerine Psittacidae families. These were recovered Rio...
Salmonella is one of the major causative agents foodborne infections. In this study, 225 samples different types cheeses produced by Brazilian dairy industry were analysed. Samples submitted to a spp. investigation using conventional microbiology, multiplex polymerase chain reaction (multiplex PCR) and disc‐diffusion method. The occurrence was 1.33% (3/225); two strains ( S . Infantis Schwarzengrund) detected in Prato cheese, strain S. Anatum) Mozzarella cheese. three showed resistance...
Aeromonads are natural inhabitants of aquatic environments and may be associated with various human or animal diseases. Its pathogenicity is complex multifactorial many virulence factors.
