Department of Bacteriology, Pasteur Institute of Iran, Tehran, Iran.
Background: is a significant cause of healthcare-associated infections, with rising antimicrobial resistance complicating treatment. This study offers a genomic analysis of , focusing on sequence types (STs), global distribution, antibiotic resistance genes, and virulence factors in its chromosomal and plasmid DNA.
Methods: A total of 19,711 genomes were retrieved from GenBank.
Resistance to medically important antimicrobials in broiler and layer farms in Cameroon and its relation with biosecurity and antimicrobial use.

Introduction: Poultry production accounts for 42% of Cameroonian meat production. However, infectious diseases represent the main hindrance in this sector, resulting in overuse and misuse of antimicrobials that can contribute to the emergence and dissemination of antimicrobial resistance (AMR). This study aimed to evaluate the prevalence of antimicrobial resistance genes (ARGs) conferring resistance to carbapenems ( and ), (fluoro) quinolones (, , and ), polymyxins ( to ), and macrolides ( and ) in the poultry farm environment.

The effect of on the viability and antimicrobial activity of the ectoparasitoid was evaluated in laboratory experiments. Two lines of the parasitoid, -infected (W+) and -free (W-), were used. Parasitoid larvae were fed with a host orally infected with a sublethal dose of (Bt) and on the host uninfected with Bt.

Electronic address:
The usage of quaternary ammonium compounds (QACs) as disinfectants has surged dramatically during the COVID-19 pandemic and thereafter. QACs can promote antimicrobial resistance, but the combined effects of QACs and antibiotics in driving resistance evolution were yet revealed. This study aimed to evaluate antibiotic resistance of wastewater microorganisms under coexposure to typical antibiotics and the most widely used QAC, dodecyl dimethyl benzyl ammonium chloride (DDBAC).

Laboratoire de Bactériologie, CHU Félix Guyon, Allée des Topazes, 97400, Saint-Denis, La Réunion, France.
Aim: Located in the Southwest Indian Ocean area (SIOA), the two French overseas territories (FOTs) of Reunion and Mayotte islands are heavily impacted by antimicrobial resistance. The aim of this study was to investigate all cases of NDM-5 and OXA-181 carbapenemase-producing Escherichia coli (CPEc) in these two FOTs between 2015 and 2020, to better understand the regional spread of these last-line treatment resistant bacteria.
