Extended-spectrum β-lactamases (ESBLs) are β-lactamase enzymes produced by Gram-negative bacterial pathogens that harbor the ESBL genes. In addition, most ESBL genes are plasmid-mediated and usually encode a broader spectrum of antimicrobial resistance, especially to penicillins, first-generation, second-generation, and third-generation cephalosporins, as well as monobactam, such as aztreonam. has become an opportunistic pathogen, especially in poultry, and has been implicated in zoonotic diseases that can be transmitted to humans, resulting in public health problems.

Background: The exploratory study assessed trends in the abundance of CTX-M-type extended spectrum beta-lactamase (ESBL) and vancomycin-resistance genes vanA and vanB in the stool samples of German soldiers and police officers returning from predominantly tropical deployments next to the common diarrheagenic Escherichia (E.) coli pathovars enteropathogenic Escherichia coli (EPEC), enterotoxigenic E. coli (ETEC) and enteroaggregative E.

Unlabelled: The prevalence of infections caused by extended-spectrum beta-lactamase (ESBL)-producing (ESBL-EC) and carbapenemase-producing (CP-EC) is increasing worldwide. We investigated the epidemiology of ESBL-EC and CP-EC causing hospital-acquired (HA) infections in a large teaching hospital in Tunisia over the last two decades and compared it with a collection of 107 community-acquired (CA) ESBL-EC isolates. Between 2001 and 2019, the incidence of HA ESBL-EC increased significantly from 0.

Antimicrobials reserved for human medicines are permitted for companion animals and it is important to understand multidrug-resistant pathogens recovered from companion animals in terms of epidemiological correlation with human pathogens and possibility of transmission to human-beings. Seventeen of each CTX-M-type extended-spectrum beta-lactamase-producing Escherichia coli (ESBL-EC) and Klebsiella pneumoniae (ESBL-KP) canine isolates were assessed. Entire genomes of the 34 isolates were sequenced.
