The emergence and rapid spread of carbapenemase-producing Enterobacterales represents a serious public health concern. Critically, these global priority bacteria have begun to be reported in companion animals, implying a potential risk of cross-transmission between humans and pets. Using long-read (MinION) and short-read (Illumina) sequencing technologies, we have identified and characterized a hypermucoviscous KPC-2-producing Klebsiella pneumoniae strain belonging to the high-risk international clone ST11/CG258, in a dog with urinary tract infection. Strikingly, the bla gene was carried by a 54-kb IncN plasmid assignated to ST15, which shared 99.8 and 96.8% pairwise identity with IncN-pST15 plasmids from human and environmental K. pneumoniae strains, respectively; all come from an area with high endemicity of KPC-2. Our findings suggest that IncN-pST15 plasmids conferring carbapenem resistance can play as important a role as clonal transmission of K. pneumoniae, representing another major challenge for One Health.

Background: As an opportunistic bacterial pathogen, Klebsiella pneumoniae (KP) is prone to causing a spectrum of diseases in rabbits when their immune system is compromised, which poses a threat to rabbit breeding industry. Bacillus coagulans (BC), recognized as an effective probiotic, confers a variety of benefits including anti-inflammatory and antioxidant properties.

Aim: The purpose of this study was to investigate whether dietary BC can effectively alleviate hepatic injury caused by KP.

Rationale: Carbapenem-resistant Klebsiella pneumoniae (CRKP) bloodstream infections are a severe complication resulting from granulocyte deficiency following chemotherapy for hematologic malignancies and have a high mortality rate. However, reports of disseminated organ infections secondary to bloodstream infections are rare.

Patient Concerns And Diagnoses: We report 2 cases of patients with acute lymphoblastic leukemia who both developed CRKP bloodstream infections during the granulocyte deficiency stage following chemotherapy, with 1 case of secondary bacterial liver abscess and 1 case of secondary septic arthritis.

Genes encoding OXA-48-like carbapenem-hydrolyzing enzymes are often located on plasmids and are abundant among carbapenemase-producing (CPE) worldwide. After a large plasmid-mediated outbreak in 2011, routine screening of patients at risk of CPE carriage on admission and every 7 days during hospitalization was implemented in a large hospital in the Netherlands. The objective of this study was to investigate the dynamics of the hospitals' 2011 outbreak-associated plasmid among CPE collected from 2011 to 2021.

is a gram-negative pathogen that can cause multiple diseases including sepsis, urinary tract infections, and pneumonia. The escalating detections of hypervirulent and antibiotic-resistant isolates are giving rise to growing public concerns. Outer membrane vesicles (OMVs) are spherical vesicles containing bioactive substances including lipopolysaccharides, peptidoglycans, periplasmic and cytoplasmic proteins, and nucleic acids.

The emergence of carbapenem-resistant (CRKP) poses a significant public health threat, particularly in low- and middle-income countries (LMICs) with limited surveillance and treatment options. This study examines the genetic diversity, resistance patterns, and transmission dynamics of 66 CRKP isolates recovered over 5 years (2015-2019) after the first case of CRKP was identified at a tertiary care hospital in Lima, Peru. Our findings reveal a shift from to as the dominant carbapenemase gene after 2017.
