An epidemic of nosocomial ceftazidime-resistant Klebsiella pneumoniae was correlated with production of a ceftazidime-hydrolyzing enzyme with an isoelectric point of 5.6 (BMH-1). BMH-1 was encoded on a large transferable plasmid conferring multiple antibiotic resistance. The gene that encodes BMH-1 was identical to the gene that encodes the TEM-26 extended-spectrum beta-lactamase.

Objectives: To assess the antimicrobial activity of ceftolozane/tazobactam, imipenem/relebactam and comparator agents against clinical isolates of Gram-negative bacilli collected in Israel from 2018 to 2022.

Methods: Six clinical laboratories each collected up to 250 consecutive Gram-negative isolates per year from patients with bloodstream, intra-abdominal, lower respiratory tract and urinary tract infections. MICs were determined by CLSI broth microdilution and interpreted with 2024 EUCAST breakpoints.

Objectives: To evaluate the activities of ceftolozane/tazobactam and imipenem/relebactam against clinical isolates of Gram-negative bacilli collected in four central and northern European countries (Belgium, Norway, Sweden, Switzerland) during 2017-21.

Methods: Participating clinical laboratories each collected up to 250 consecutive Gram-negative isolates per year from patients with bloodstream, intraabdominal, lower respiratory tract or urinary tract infections. MICs were determined by CLSI broth microdilution and interpreted using 2022 EUCAST breakpoints.

This review describes the translational in vivo and non-clinical pharmacokinetics/pharmacodynamics (PK/PD) research that supported clinical trialling and subsequently licensing approval of ceftazidime/avibactam, a new β-lactam/β-lactamase inhibitor combination aimed at the treatment of infections by Enterobacterales and Pseudomonas aeruginosa. The review thematically follows on from the co-published article, Nichols et al. (J Antimicrob Chemother 2022; 77: 2321-40).

The dissemination of antibiotic-resistant bacteria (ARB) from water used for crop irrigation to vegetables is poorly studied. During a year, five farmer markets in a city in Central Chile were visited, and 478 vegetable samples (parsleys, corianders, celeries, lettuces, chards, and beets) were collected. Simultaneously, 32 water samples were collected from two rivers which are used to irrigate the vegetables produced in the area.

Background: are major players in the spread of resistance to β-lactam antibiotics through the action of CTX-M β-lactamases. We aimed to analyze the diversity and genetic characteristics of ESBL-producing and isolates from patients in a Northern Portuguese hospital.

Methods: A total of 62 cefotaxime/ceftazidime-resistant ( = 38) and ( = 24) clinical isolates were studied.
