Traces of pandemic fluoroquinolone-resistant Escherichia coli clone ST131 transmitted from human society to aquatic environments and wildlife in Japan. One Health 2024; 18:100715. [PMID: 39010959 PMCID: PMC11247291 DOI: 10.1016/j.onehlt.2024.100715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 03/20/2024] [Indexed: 07/17/2024] Open
Abstract
Transmission of antimicrobial-resistant bacteria among humans, animals, and the environment is a growing concern worldwide. The distribution of an international high-risk fluoroquinolone-resistant Escherichia coli clone, ST131, has been documented in clinical settings. However, the transmission of ST131 from humans to surrounding environments remains poorly elucidated. To comprehend the current situation and identify the source of ST131 in nature, we analyzed the genetic features of ST131 isolates from the aquatic environment (lake/river water) and wildlife (fox, raccoon, raccoon dog, and deer) and compared them with the features of isolates from humans in Japan using accessory and core genome single nucleotide polymorphism (SNP) analyses. We identified ST131 isolates belonging to the same phylotype and genome clusters (four of eight clusters were concomitant) with low SNP distance between the human isolates and those from the aquatic environment and wildlife. These findings warn of ST131 transmission between humans and the surrounding environment in Japan.

Genomic landscape of bla GES-5- and bla GES-24-harboring Gram-negative bacteria from hospital wastewater: emergence of class 3 integron-associated bla GES-24 genes. J Glob Antimicrob Resist 2022; 31:196-206. [PMID: 36180037 DOI: 10.1016/j.jgar.2022.09.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Revised: 09/09/2022] [Accepted: 09/13/2022] [Indexed: 12/30/2022] Open
Abstract
OBJECTIVES This study aimed to characterize Gram negative bacteria carrying blaGES carbapenemase genes detected in wastewater from a hospital with no history of detection of clinical isolates producing GES carbapenemases. METHODS Six hospital effluent samples were screened for carbapenemase-producing organisms (CPO) using CHROMagar mSuperCARBA and MacConkey agar with 1 µg/mL imipenem. Polymerase chain reaction (PCR) amplification and sequencing of carbapenemase genes, multilocus sequence typing, antimicrobial susceptibility testing, and whole-genome sequencing were performed. RESULTS Among 21 CPO isolates, 11 Klebsiella spp. and 5 Enterobacter kobei isolates carried blaGES-24, and 4 E. roggenkampii and 1 Pseudomonas aeruginosa isolates carried blaGES-5. Genomic analysis of 8 representative isolates comprising 6 blaGES-24-positive and 2 blaGES-5-positive revealed that class 3 integrons with complete or defective Tn402-like transposition modules were predominantly associated with two tandem copies of blaGES-24. Furthermore, a total of 5 new class 3 integrons, In3-18 to In3-22, were identified among 5 blaGES-24 and 1 blaGES-5 plasmids. One strain each of K. pneumoniae subsp. pneumoniae and K. quasipneumoniae subsp. similipneumoniae harboring blaGES-24 plasmids also carried a rare blaVEB-1-positive class 1 integron on a non-typeable plasmid, where these blaVEB-1 plasmids had high sequence similarity. Virulence gene profiles differed between Klebsiella spp. and Enterobacter spp.; the former harbored type III fimbriae cluster, salmochelin, and T6SS type i2 gene clusters, while the latter had curli pili operon, aerobactin, T2SS gene clusters, and T6SS type i3 gene clusters. CONCLUSION Our findings confirmed the linkage of blaGES-24 with rare Tn402-like class 3 integrons and the structural diversity of their gene cassette arrays.

J Vet Med Sci 2021; 83:1191-1195. [PMID: 34108337 PMCID: PMC8437729 DOI: 10.1292/jvms.21-0108] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 05/24/2021] [Indexed: 11/22/2022] Open
Abstract
Wild birds are recognized as disseminators of antimicrobial-resistant (AMR) bacteria into the environment. Here, we isolated AMR indicator bacteria from 198 Great Cormorant cloacal swabs collected in Shiga (n=90), Oita (n=52), Gifu (n=29), and Gunma (n=27) Prefectures, Japan, in 2018 and 2019. In total, 198 Aeromonas spp. and 194 Escherichia spp. were isolated, and their antimicrobial susceptibility was examined. Aeromonas spp. were resistant to colistin (8.6%), nalidixic acid (4%), and other antimicrobials (<2%), with 3.0% positivity for mcr-3. Escherichia spp. showed resistance to colistin (3.1%), ampicillin (2.6%), tetracycline (2.1%), and other antimicrobials (<2%). This study shows the presence of AMR bacteria in Great Cormorants, indicating that these birds potentially disseminate AMR bacteria.
