is a high-priority bacterial agent that causes healthcare-acquired infections (HAIs), which often leads to serious infections and poor prognosis in vulnerable patients. Its increasing resistance to antimicrobials, associated with SPM production, is a case of public health concern. Therefore, this study aims to determine the antimicrobial resistance, virulence, and genotyping features of strains producing SPM-1 in the Northern region of Brazil.

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) isolates in the nosocomial settings, herein, we described isolates of this extensively drug-resistant (XDR) species recovered from stool samples of food-producing animals in the Brazilian Amazon region. Three carbapenem-resistant strains were recovered from stool samples of poultry and cattle.

Article Synopsis
  • * Researchers used methods like antibiotic susceptibility tests and whole genome sequencing to characterize the isolate, revealing it as extensively drug-resistant and belonging to a high-risk genetic clone associated with multiple resistance genes.
  • * The findings highlight the urgent need for improved surveillance and research on antibiotic resistance, particularly in vulnerable areas like the Amazon, to combat the threat posed by these resistant bacterial strains.

Carbapenem-resistant Klebsiella pneumoniae is a common cause of healthcare-related infections, and it is widespread in hospitals and diverse environments with potentially serious public health implications. Herein, we have reported the isolation and characterization of an environmental Brazilian Klebsiella carbapenemase (BKC-1)-producing K. pneumoniae strain (IEC1205) isolated in 2018 from a river in the Amazon region, Brazil.

Carbapenem resistance among isolates is often related to carbapenemase genes, located in genetic transmissible elements, particularly the gene, which variants are spread in several countries. Recently, reports of isolates harboring the gene have increased dramatically along with the dissemination of epidemic high-risk clones (HRCs). In the present study, we report the multiclonal spread of New Delhi metallo-beta-lactamase (NDM)-producing in different healthcare institutions in the state of Pará, Northern Brazil.

This study developed a computational tool with a graphical interface and a web-service that allows the identification of phage regions through homology search and gene clustering. It uses G+C content variation evaluation and tRNA prediction sites as evidence to reinforce the presence of prophages in indeterminate regions. Also, it performs the functional characterization of the prophages regions through data integration of biological databases.
