Analysis of an IncR plasmid carried by carbapenem-resistant Klebsiella pneumoniae: A survey of swine Klebsiella pneumoniae in Jilin Province. J Glob Antimicrob Resist 2023; 34:83-90. [PMID: 37210003 DOI: 10.1016/j.jgar.2023.04.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 04/20/2023] [Accepted: 04/27/2023] [Indexed: 05/22/2023] Open
Abstract
OBJECTIVES This study was conducted in Jilin Province to investigate the mechanism involved in the antibiotic resistance and pathogenicity of Klebsiella pneumoniae. METHODS Lung samples were collected from large-scale pig farms in Jilin Province. Antimicrobial susceptibility and mouse lethality assays were carried out. K. pneumoniae isolate JP20, with high virulence and antibiotic resistance, was chosen for whole-genome sequencing. The complete sequence of its genome was annotated, and the virulence and antibiotic resistance mechanism were analysed. RESULTS A total of 32 K. pneumoniae strains were isolated and tested for antibiotic resistance and pathogenicity. Among them, the JP20 strain showed high levels of resistance to all tested antimicrobial agents and strong pathogenicity in mice (lethal dose of 1.35 × 1011 CFU/mL). Sequencing of the multidrug-resistant and highly virulent K. pneumoniae JP20 strain revealed that the antibiotic resistance genes were mainly carried by an IncR plasmid. We speculate that extended-spectrum β-lactamases and loss of outer membrane porin OmpK36 play an important role in carbapenem antibiotic resistance. This plasmid contains a mosaic structure consisting of a large number of mobile elements. CONCLUSION Through genome-wide analysis, we found that an lncR plasmid carried by the JP20 strain may have evolved in pig farms, possibly leading to multidrug resistance in the JP20 strain. It is speculated that the antibiotic resistance of K. pneumoniae in pig farms is mainly mediated by mobile elements (insertion sequences, transposons, and plasmids). These data provide a basis for monitoring the antibiotic resistance of K. pneumoniae and lay a foundation for an improved understanding of the genomic characteristics and antibiotic resistance mechanism of K. pneumoniae.

Comparative analysis of fecal microbiota composition diversity in Tibetan piglets suffering from diarrheagenic Escherichia coli (DEC). Microb Pathog 2021; 158:105106. [PMID: 34311015 DOI: 10.1016/j.micpath.2021.105106] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 06/29/2021] [Accepted: 07/20/2021] [Indexed: 02/06/2023]
Abstract
This study was ascertained to investigate the adverse effects of pathogenic E. coli on gut microbiota of Tibetan piglets with history of yellow and white dysentery. For this purpose, a total of 18 fecal samples were collected from infected and healthy Tibetan piglets for 16S rRNA gene amplification and sequencing of V3-V4 region. Results showed that Firmicutes, Bacteroidia Fusobacteriota, Proteobacteria and Actinobacteriota were the predominant bacteria in Tibetan piglets at the level of phylum classification. Results on classification at family level showed that Lactobacillus, Bacteroidota, Fusobacteriota and Enterobacteriaceae were the dominant bacteria. Results on classification of bacteria at phylum level compared with normal piglets indicated that Bacteroidota, Actinobacteriota, Euryarchaota and Spirochaetota in fecal microbial community in Tibetan piglets showing yellow dysenteric and diarrhea group were significantly decreased (P ≤ 0.05). Compared with the feces of healthy Tibetan piglets, the abundance of Escherichia-Shigella, Lactobacillus and Enterococcus increased significantly in feces of Tibetan piglets having yellow dysentery and white dysentery. Moreover, results exhibited that the Proteobacteria and Fusobacteriota were significantly increased (P ≤ 0.05) suggesting dominant microbial community. Results revealed that E. coli induced different pathological alterations in intestine including damage to intestinal epithelial cells, infiltration of inflammatory cells, presence of red blood cells in spaces of tissues, hemorrhages and necrosis of intestinal villi in piglets with history of yellow dysentery. This study for the first time reported the composition, characteristics, and differences of the fecal microflora diversity of Tibetan piglets with yellow and white dysentery in Qinghai-Tibet Plateau, which can provide a suitable support for effective control of diarrhoeal disease in these animals.

Abstract
Bacillus cereus is a common and ubiquitous foodborne pathogen with an increasing prevalence rate in dairy products in China. High and unmet demands for such products, particularly milk, raise the risk of B. cereus associated contamination. The presence of B. cereus and its virulence factors in dairy products may cause food poisoning and other illnesses. Thus, this review first summarizes the epidemiological characteristics and analytical assays of B. cereus from dairy products in China, providing insights into the implementation of intervention strategies. In addition, the recent achievements on the cytotoxicity and mechanisms of B. cereus are also presented to shed light on the therapeutic options for B. cereus associated infections.
