Clinical emergent bacterial pathogens are a great threat to the global health system, chiefly Gram-negative carbapenem-resistant Enterobacterales and Klebsiella pneumoniae species complex. Here, we present molecular phenotypic characterization of quasipneumoniae subs. similipneumoniae IEC57090 strain, belonging ST138 showing multidrug resistance phenotype. The blaNDM-7 in one two plasmids carried by isolate, antibiotic genes fosA, oqxAB, acrR, gene mutations on porins ompK36 ompK37, both...
Pseudomonas aeruginosa is a major pathogen in cystic fibrosis (CF), where chronic and intermittent infections significantly affect patient outcomes. This study aimed to investigate the molecular epidemiology of P. CF patients from Brazilian Amazon, focusing on genotypic diversity, resistance profiles, virulence factors. A cross-sectional included 72 isolates 44 treated at regional reference center between 2018 2019. Antimicrobial susceptibility patterns were determined using VITEK-2 system...
Pseudomonas aeruginosa is a high-priority bacterial agent that causes healthcare-acquired infections (HAIs), which often leads to serious and poor prognosis in vulnerable patients. Its increasing resistance antimicrobials, associated with SPM production, case of public health concern. Therefore, this study aims determine the antimicrobial resistance, virulence, genotyping features P. strains producing SPM-1 Northern region Brazil. To presence virulence genes, PCR technique was used. For...

Abstract Objectives To characterize a novel acquired MBL, BIM-1, in Pseudomonas #2 (subgroup P. guariconensis) strain isolated from the Aurá river located Brazilian Amazon hydrographic basin. Methods WGS using an Illumina® MiSeq System was used to genome of sp. IEC33019 strain. Southern blotting/hybridization assays were performed confirm location MBL-encoding gene, blaBIM-1 (Belém Imipenemase). Antimicrobial susceptibility testing, cloning, and biochemical phenotypic characterization...
Abstract Aims The present study aimed to use a conventional and metagenomic approach investigate the microbiological diversity of water bodies in network drainage channels rivers located central area city Belém, northern Brazil, which is considered one largest cities Brazilian Amazon. Methods results In eight analyzed points, both bacterial viral indicators environmental contamination—physical–chemical metals—were assessed. resistance genes, drug mechanisms, viability environment were also A...
Introduction: Genital Chlamydia trachomatis infection is one of the most prevalent sexually transmitted diseases in women, and undetected cases disease are highly associated with long-term complications. Despite high prevalence infections Brazil, very little known about distribution C. genovars. In this study, we determined genotypes women treated at a public hospital Brazilian city Belém, capital state Pará. Methodology: A total 154 were tested for chlamydial by PCR using specific primers...
Background Chlamydia trachomatis is the most prevalent bacterial sexually transmitted infection (STI) in world. Approximately 80% of infected women are asymptomatic, although this can lead to serious complications female reproductive tract. Few data on available rural Amazonian communities. Objectives To evaluate prevalence sexual C. from Marajó Archipelago communities Amazon region Brazil and identify associated factors genotypes. Methods We utilized amplification ompA gene by nested PCR....
Serratia marcescens is a Gram-negative bacterium presenting intrinsic resistance to polymyxins that has emerged as an important human pathogen. Although previous studies reported the occurrence of multidrug-resistance (MDR) S. isolates in nosocomial settings, herein, we described this extensively drug-resistant (XDR) species recovered from stool samples food-producing animals Brazilian Amazon region. Three carbapenem-resistant strains were poultry and cattle. Genetic similarity analysis...
OBJETIVOS: Descrever a prevalência e os fatores associados à infecção endocervical por Chlamydia trachomatis em estudantes de uma universidade da capital três seus campi do interior estado Pará, Amazônia, Brasil.
The multidrug resistance (MDR) phenotype is frequently observed in Acinetobacter baumannii, the most clinically relevant pathogenic species of its genus; recently, other belonging to A. calcoaceticus-A. baumannii complex have emerged as important MDR nosocomial pathogens.The present study aimed verify occurrence metallo-β-lactamase genes among distinct a hospital located Brazilian Amazon Region.Antimicrobial susceptibility profiles were determined by broth microdilution. genetic...
Abstract The One Health concept is a global strategy to study the relationship between human and animal health transfer of pathogenic non-pathogenic species these systems. However, best our knowledge, no data based on genome-centric metagenomics are available in public repositories. Here, we present dataset pilot-study 2,915 metagenome-assembled genomes (MAGs) 107 samples from (N = 34), cattle 28), swine 15) poultry 30) gut microbiomes. Samples were collected five Brazilian geographical...
The epidemiology of antimicrobial resistance (AMR) is complex, with multiple interfaces (human-animal-environment). In this context, One Health surveillance essential for understanding the distribution microorganisms and genes (ARGs). This report describes a multicentric study undertaken to evaluate bacterial communities resistomes food-producing animals (cattle, poultry, swine) healthy humans sampled simultaneously from five Brazilian regions. Metagenomic analysis showed that total 21,029...
Background Approximately 80% of infected women by Chlamydia trachomatis are asymptomatic, although this infection can lead to serious complications in the female reproductive tract. Few data on and genotypes available Amazonian communities. Objectives To describe prevalence associated factors identify sexual C . university students different urban centers (capital interiors) Brazilian state Pará, eastern Amazon region. Methods A cross-sectional study was performed among young attending...
This study aimed to characterize a Klebsiella pneumoniae strain (KP411) recovered from the stool samples of poultry (Gallus gallus) in Brazilian Amazon Region. The whole-genome sequencing KP411 revealed presence an important arsenal antimicrobial resistance genes β-lactams (blaCTX-M-14, blaTEM-1B, blaKPC-2, blaSVH-11), aminoglycosides [aph(3″)- Ib, aph(6)-Id, aph(3′)-Ia], sulfonamides (sul1, sul2), quinolones (oqxAB), fosfomycin (fosAKP), and macrolides [mph(A)]. Furthermore, our analyses...
The horizontal transfer of antibiotic resistance genes in Gram-negative bacteria, mainly through plasmids, is one the greatest concerns for health systems worldwide and has been a growing threat hospitals related to healthcare-associated infections by multidrug-resistant bacteria. Here we present p henotypic genomic characterization KPC-2 MCR-1.27-producing Klebsiella pneumoniae strain isolated from paediatric patient at an oncologic hospital Belém, Pará State, Brazilian Amazon...
Surgical site infection (SSI) following caesarean section is associated with increased morbidity, mortality, and significant health care costs.
