Article Abstract
We developed a faster and more convenient method to determine integration frequency mediated by integron integrase intI1. This method based on real-time fluorescent quantitative PCR. By using this method, we revealed that the integration frequency of aadA2 gene cassette was 1.87x10(-4) when integrase intI1 was present, and the background frequency was less than 5.23x10(-8) without integrase intI1.

Unlabelled: The environmental pollution from the misuse of antimicrobial drugs is fueling selection pressure in bacteria, thereby exacerbating the threat to global health. In Iraq, the situation is made worse by the poor implementation of the World Health Organization's Global Antimicrobial Resistance and Use Surveillance System (WHO-GLASS). Consequently, this study aimed to increase surveillance of the spread of antimicrobial resistance in Sulaymaniyah, Iraq.

Improperly treated wastewater and surface runoff can degrade water quality by introducing microbial contaminants, including antibiotic-resistant bacteria (ARB) and their genes (ARGs). Constructed treatment wetlands (CTWs) offer a low-resource solution for managing impaired watersheds. However, their ability to mitigate microbial contaminants, particularly ARGs, requires further study.

Introduction: A retrospective study of non-typhoidal isolation from poultry and pig farms in Nakhon Pathom and Suphan Buri provinces was conducted from 2008 to 2015. The aim of study was to examine the prevalence of antimicrobial resistance and class I integrons related to gene resistance of in livestock and its environment.
Methods: A total of 636 isolates was collected from livestock and environmental samples.

Stenotrophomonas maltophilia is an opportunistic pathogen that can cause infections especially in hospital settings and in immunocompromised individuals. Due to its resistance to many broad-spectrum antibiotics, treatment options that can be used in clinical practice are limited. This study aims to evaluate the susceptibility profiles of S.

: Poultry litter is the main waste of poultry farming and is widely used as an agricultural fertilizer. However, owing to the use of antimicrobials in animal production, it can accumulate antimicrobial residues, antimicrobial-resistant bacteria (ARB), and antimicrobial resistance genes (ARGs). This study aimed to evaluate the impact of poultry litter use on the microbiome and resistome of agricultural soils.
