Abstract
The global food trade provides a means of disseminating antimicrobial resistant (AMR) bacteria and genes. Using selective media, carbapenem-resistant species of Enterobacterales (Providencia sp. and Citrobacter sp.), were detected in a single package of imported frozen shrimp purchased from a grocery store in Ohio, USA. Polymerase chain reaction confirmed that both isolates harbored blaNDM-1 genes. Following PacBio long read sequencing, the sequences were annotated using the NCBI Prokaryotic Genome Annotation Pipeline. The blaNDM-1 genes were found in IncC plasmids, each with different antimicrobial resistance island configuration. We found that the blaNDM-1 AMR islands had close relationships with previously reported environmental, food, and clinical isolates detected in Asia and the United States, highlighting the importance of the food chain in the global dissemination of antimicrobial resistance.

Abstract
Raoultella planticola is an emerging bacterial pathogen responsible for causing infections in both humans and animals. Unfortunately, sporadic reports of carbapenem-resistant R. planticola (CRRP) have been documented worldwide. Here we first reported the complete genome sequence of a CRRP isolate RP_3045 co-carrying blaIMP-4 and blaSHV-12, recovered from a patient in China, and its genetic relatedness to 82 R. planticola strains deposited in the NCBI GenBank database, sourced from humans, animals, and the environment. Whole-genome sequencing was performed using the Illumina NovaSeq 6000 and Oxford Nanopore MinION platforms. Phylogenetic analysis was also performed and visualized using a single nucleotide polymorphism (SNP)-based strategy. The complete genome of R. planticola strain RP_3045 was determined to be 6,312,961 bp in length, comprising five contigs that included one chromosome and four plasmids. RP_3045 was found to be multidrug-resistant and harbored several antimicrobial resistance genes, including both blaIMP-4 and blaSHV-12 genes located on a single plasmid. The most closely related strain was hkcpe63, recovered from humans in Hong Kong, China, in 2014, with 506 SNP differences. R. planticola strains were distributed globally and exhibited strong associations among isolates obtained from different sectors. This study provides evidence for the potential of R. planticola to disseminate carbapenem resistance across different sectors, highlighting the critical need for active and continuous surveillance of CRRP.

Abstract
Introduction The tigecycline-resistant Enterobacterales have emerged as a great public concern, and the mobile tet(X) variants and tmexCD-toprJ efflux pump are mainly responsible for the spread of tigecycline resistance. Hospital sewage is considered as an important reservoir of antimicrobial resistance, while tigecycline resistance in this niche is under-researched. Methods In this study, five Escherichia coli and six Klebsiella pneumoniae strains were selected from a collection of tigecycline-resistant Enterobacterales for further investigation by antimicrobial susceptibility testing, conjugation, whole-genome sequencing, and bioinformatics analysis. Results All five E. coli strains harbored tet(X4), which was located on different plasmids, including a novel IncC/IncFIA(HI1)/IncHI1A/IncHI1B(R27) hybrid structure. In addition, tet(X4)-bearing plasmids were able to transfer by conjugation and be stabilized in the recipient in the absence of antibiotics. tmexCD1-toprJ1 was identified in two K. pneumoniae (LZSFT39 and LZSRT3) and it was carried by a novel multidrug-resistance transposon, designated Tn7368, on a novel IncR/IncU hybrid plasmid. In addition, we found that two K. pneumoniae (LZSFZT3 and LZSRT3) showed overexpression of efflux genes acrB and oqxB, respectively, which was most likely to be caused by mutations in ramR and oqxR. Discussion In conclusion, the findings in this study expand our knowledge of the genetic elements that carry tigecycline resistance genes, which establishes a baseline for investigating the structure diversity and evolutionary trajectories of human, animal, and environmental tigecycline resistomes.

Abstract
The spread of antibiotic resistance genes (ARGs) in the environment exacerbates the contamination of these genes; therefore, the role plants play in the transmission of resistance genes in the food chain requires further research. Giant pandas consume different bamboo parts at different times, which provides the possibility of investigating how a single food source can affect the variation in the spread of ARGs. In this study, metagenomic analysis and the Comprehensive Antibiotic Resistance Database (CARD) database were used to annotate ARGs and the differences in gut microbiota ARGs during the consumption of bamboo shoots, leaves, and culms by captive giant pandas. These ARGs were then compared to investigate the impact of bamboo part consumption on the spread of ARGs. The results showed that the number of ARGs in the gut microbiota of the subjects was highest during the consumption of bamboo leaves, while the variety of ARGs was highest during the consumption of shoots. Escherichia coli, which poses a higher risk of ARG dissemination, was significantly higher in the leaf group, while Klebsiella, Enterobacter, and Raoultella were significantly higher in the shoot group. The ARG risk brought by bamboo shoots and leaves may originate from soil and environmental pollution. It is recommended to handle the feces of giant pandas properly and regularly monitor the antimicrobial and virulence genes in their gut microbiota to mitigate the threat of antibiotic resistance.

Abstract
Raoultella ornithinolytica is an encapsulated, Gram-negative, nonmotile, rod belonging to the Enterobacteriaceae family. Infections involving the gastrointestinal tract and the hepatopancreatobiliary system are most frequently reported, especially in immunocompromised patients. The authors present an unusual case of acute complicated sinusitis with orbital and intracranial involvement caused by R. ornithinolytica. The infection was rapidly progressive, even though the patient was a healthy, young person without any co-morbidities. The patient's condition improved after antibiotic treatment and multiple ophthalmic and sinus surgeries. LEARNING POINTS Raoultella ornithinolytica can cause rapidly progressive infections, even in immunocompetent young individuals.Raoultella ornithinolytica identified in sinusitis can be a true pathogen rather than an innocent bystander.

Abstract
Raoultella planticola harboring genes that confer resistance to antimicrobials, such as carbapenems, have been associated with severe infections in immunocompromised patients. In this study, we reported the first whole genome sequence of a Brazilian isolate of R. planticola and the genomic context of antibiotic resistance markers. By whole-genome sequencing (WGS) of a carbapenem-resistant R. planticola isolate, RpHUM1, we found 23 resistance-encoding genes belonging to 9 classes of antibiotics (aminoglycosides, β-lactams, fluoroquinolones, fosfomycin, macrolides, phenicols, sulfonamides, tetracycline, and diaminopyrimidine derivatives) and 3 plasmids (RpHUM1pEaer-4382s, RpHUM1_pFDAARGOS_440, and RpHUM1pRSF1010). This isolate coharbored the genes blaKPC-2, which is carried by the plasmid RpHUM1pEaer-4382s, and blaNDM-1 and blaCTX-M-15 all located in the accessory genome. In addition, these genes were associated with, at least, one mobile genetic element. This comprehensive knowledge is of great importance for implementation of control measures to prevent the rapid dissemination of this neglected microorganism and their genetic resistance background.

Emergence of Raoultella ornithinolytica in human infections from different hospitals in Ecuador with OXA-48-producing resistance. Front Microbiol 2023; 14:1216008.

Abstract
Purpose The purpose of this study was to highlight the clinical and molecular features of 13 Raoultella ornithinolytica strains isolated from clinical environments in Ecuador, and to perform comparative genomics with previously published genomes of Raoultella spp. As Raoultella is primarily found in environmental, clinical settings, we focused our work on identifying mechanisms of resistance that can provide this bacterium an advantage to establish and persist in hospital environments. Methods We analyzed 13 strains of Raoultella ornithinolytica isolated from patients with healthcare associated infections (HAI) in three hospitals in Quito and one in Santo Domingo de Los Tsáchilas, Ecuador, between November 2017 and April 2018. These isolates were subjected to phenotypic antimicrobial susceptibility testing, end-point polymerase chain reaction (PCR) to detect the presence of carbapenemases and whole-genome sequencing. Results Polymerase chain reaction revealed that seven isolates were positive isolates for blaOXA-48 and one for blaKPC-2 gene. Of the seven strains that presented the blaOXA-48 gene, six harbored it on an IncFII plasmid, one was inserted into the bacterial chromosome. The blaKPC gene was detected in an IncM2/IncR plasmid. From the bioinformatics analysis, nine genomes had the gene blaOXA-48, originating from Ecuador. Moreover, all R. ornithinolytica strains contained the ORN-1 gene, which confers resistance for β-lactams, such as penicillins and cephalosporins. Comparative genome analysis of the strains showed that the pangenome of R. ornithinolytica is considered an open pangenome, with 27.77% of core genes, which could be explained by the fact that the antibiotic resistance genes in the ancestral reconstruction are relatively new, suggesting that this genome is constantly incorporating new genes. Conclusion These results reveal the genome plasticity of R. ornithinolytica, particularly in acquiring antibiotic-resistance genes. The genomic surveillance and infectious control of these uncommon species are important since they may contribute to the burden of antimicrobial resistance and human health.

Abstract
Antimicrobial resistance, especially carbapenem resistance, poses a serious threat to global public health. Here, a carbapenem-resistant Comamonas aquatica isolate SCLZS63 was recovered from hospital sewage. Whole-genome sequencing showed that SCLZS63 has a 4,048,791-bp circular chromosome and three plasmids. The carbapenemase gene blaAFM-1 is located on the 143,067-bp untypable plasmid p1_SCLZS63, which is a novel type of plasmid with two multidrug-resistant (MDR) regions. Notably, a novel class A serine β-lactamase gene, blaCAE-1, coexists with blaAFM-1 in the mosaic MDR2 region. Cloning assay showed that CAE-1 confers resistance to ampicillin, piperacillin, cefazolin, cefuroxime, and ceftriaxone, and elevates the MIC of ampicillin-sulbactam two-fold in Escherichia coli DH5α, suggesting that CAE-1 functions as a broad-spectrum β-lactamase. Amino acid sequences analysis suggested that blaCAE-1 may originate from Comamonadaceae. The blaAFM-1 in p1_SCLZS63 is located in a conserved structure of ISCR29-ΔgroL-blaAFM-1-ble-ΔtrpF-ΔISCR27-msrB-msrA-yfcG-corA. Comprehensive analysis of the blaAFM-bearing sequences revealed important roles of ISCR29 and ΔISCR27 in the mobilization and truncation of the core module of blaAFM alleles, respectively. The diverse passenger contents of class 1 integrons flanking the blaAFM core module make the complexity of genetic contexts for blaAFM. In conclusion, this study reveals that Comamonas may act as an important reservoir for antibiotics-resistance genes and plasmids in the environment. Continuous monitoring for the environmental emergence of antimicrobial-resistant bacteria is needed to control the spread of antimicrobial resistance.

Abstract
Introduction Tigecycline and carbapenems are considered the last line of defense against microbial infections. The co-occurrence of resistance genes conferring resistance to both tigecycline and carbapenems in Pseudomononas asiatica was not investigated. Methods P. asiatica A28 was isolated from hospital sewage. Antibiotic susceptibility testing showed resistance to carbapenem and tigecycline. WGS was performed to analyze the antimicrobial resistance genes and genetic characteristics. Plasmid transfer by conjugation was investigated. Plasmid fitness costs were evaluated in Pseudomonas aeruginosa transconjugants including a Galleria mellonella infection model. Results Meropenem and tigecycline resistant P. asiatica A28 carries a 199, 972 bp long plasmid PLA28.4 which harbors seven resistance genes. Sequence analysis showed that the 7113 bp transposon Tn7389 is made up of a class I integron without a 5'CS terminal and a complete tni module flanked by a pair of 25bp insertion repeats. Additionally, the Tn7493 transposon, 20.24 kp long, with a complete 38-bp Tn1403 IR and an incomplete 30-bp Tn1403 IR, is made up of partial skeleton of Tn1403, a class I integron harboring bla OXA-10, and a Tn5563a transposon. Moreover, one tnfxB3-tmexC3.2-tmexD3b-toprJ1b cluster was found in the plasmid and another one in the the chromosome. Furthermore, plasmid PLA28.4 could be conjugated to P. aeruginosa PAO1, with high fitness cost. Discussion A multidrug-resistant plasmid carrying tmexCD3-toprJ1b and two novel transposons carrying bla VIM-2 and bla OXA-10 -resistant genes was found in hospital sewage, increasing the risk of transmission of antibiotic-resistant genes. These finding highlight the necessary of controlling the development and spread of medication resistance requires continuous monitoring and management of resistant microorganisms in hospital sewage.

Front Microbiol 2022; 13:977356. [PMID: 36090113 PMCID: PMC9449695 DOI: 10.3389/fmicb.2022.977356] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Accepted: 08/05/2022] [Indexed: 11/22/2022] Open
Abstract
Multidrug-resistant (MDR) Proteus, especially those strains producing extended-spectrum β-lactamases (ESBL) and carbapenemases, represents a major public health concern. In the present work, we characterized 27 MDR Proteus clinical isolates, including 23 Proteus mirabilis, three Proteus terrae, and one Proteus faecis, by whole-genome analysis. Among the 27 isolates analyzed, SXT/R391 ICEs were detected in 14 strains, and the complete sequences of nine ICEs were obtained. These ICEs share a common backbone structure but also have different gene contents in hotspots and variable regions. Among them, ICEPmiChn2826, ICEPmiChn2833, ICEPmiChn3105, and ICEPmiChn3725 contain abundant antibiotic resistance genes, including the ESBL gene blaCTX-M-65. The core gene phylogenetic analysis of ICEs showed their genetic diversity, and revealed the cryptic dissemination of them in Proteus strains from food animals and humans on a China-wide scale. One of the isolates, FZP3105, acquired an NDM-1-producing MDR plasmid, designated pNDM_FZP3105, which is a self-transmissible type 1/2 hybrid IncC plasmid. Analysis of the genetic organization showed that pNDM_FZP3105 has two novel antibiotic resistance islands bearing abundant antibiotic resistance genes, among which blaNDM-1 is located in a 9.0 kb ΔTn125 bracketed by two copies of IS26 in the same direction. In isolates FZP2936 and FZP3115, blaKPC-2 was detected on an IncN plasmid, which is identical to the previously reported pT211 in Zhejiang province of China. Besides, a MDR genomic island PmGRI1, a variant of PmGRI1-YN9 from chicken in China, was identified on their chromosome. In conclusion, this study demonstrates abundant genetic diversity of mobile genetic elements carrying antibiotic resistance genes, especially ESBL and carbapenemase genes, in clinical Proteus isolates, and highlights that the continuous monitoring on their transmission and further evolution is needed.
