Prolonged febrile illness due to CTX-M-15 extended-spectrum β-lactamase-producing <i>Klebsiella pneumoniae</i> infection in Nigeria.

Project description:We report on an 8-year-old patient with septicaemia unresponsive to therapy for five weeks. Undetected, extended-spectrum β-lactamase (ESBL) production by the infecting Klebsiella strain was regarded as responsible for treatment failure. Intravenously administered imipenem during the sixth week led to sustained resolution of fever. Resource-limited hospitals can incur prohibitive costs from ESBL-producer infections because of diagnostic limitations and consequent treatment failure involving prolonged supportive therapy.

First Report of an Extensively Drug-Resistant ST23 Klebsiella pneumoniae of Capsular Serotype K1 Co-Producing CTX-M-15, OXA-48 and ArmA in Spain.

Project description:An extensively drug-resistant (XDR) Klebsiella pneumoniae isolate MS3802 from a tracheostomy exudate was whole-genome sequenced using MiSeq and Oxford Nanopore MinION platforms in order to identify the antimicrobial resistance and virulence determinates and their genomic context. Isolate MS3802 belonged to the clone ST23 and presented a capsular serotype K1, associated with hypervirulent K. pneumoniae (hvKp) isolates. The isolate harboured a chromosomally encoded blaCTX-M-15 gene and contained a large IncHI1B hybrid virulence/resistance plasmid carrying another copy of the blaCTX-M-15 and the virulence factors iucABCD-iutA, iroBCDN, rmpA and rmpA2. The carbapenemase gene blaOXA-48 was found in a Tn1999-like transposon and the 16S rRNA methylase armA gen located in the vicinity of other antibiotic-resistant genes on an IncM2 plasmid. This study represents, to the best of our knowledge, the first description of a blaCTX-M-15-, blaOXA-48- and armA-harbouring K. pneumoniae of ST23 and capsular serotype K1 in Spain. Our report emphasizes the importance of implementing new surveillance strategies to monitor the risk of emergence and spread of such XDR and hypervirulent K. pneumoniae isolates.

ColE1-like plasmid pIP843 of Klebsiella pneumoniae encoding extended-spectrum beta-lactamase CTX-M-17.

Project description:The resistance of Klebsiella pneumoniae BM4493, isolated in Ho Chi Minh City, Vietnam, to cefotaxime and aztreonam was due to production of a novel beta-lactamase, CTX-M-17. The bla(CTX-M-17) gene was borne by 7,086-bp plasmid pIP843, which was entirely sequenced and which was found to belong to the ColE1 family. The 876-bp bla(CTX-M-17) gene differed from bla(CTX-M-14) by 2 nucleotides, which led to the single amino acid substitution Glu289-->Lys. bla(CTX-M-17) was flanked upstream by an ISEcp1-like element and downstream by an insertion sequence (IS) IS903 variant designated IS903-C. The transcriptional start site of bla(CTX-M-17) was located 109 nucleotides upstream from the initiation codon in the ISEcp1-like element, which also provided the promoter sequences. Plasmid pIP843, which was non-self-transferable and nonmobilizable, contained five open reading frames transcribed in the same orientation. Regions homologous to sequences coding for putative RNA II and RNA I transcripts, a rom gene, which is involved in initiation of replication, and a cer-like gene, which is responsible for the stability of ColE1-like plasmids, were identified. Consensus sequences for putative replication (oriV) and transfer (oriT) origins were present. Results of primer extension experiments indicated that ISEcp1 provides the promoter for expression of bla(CTX-M-17) and may contribute to dissemination of this gene.

The K1 beta-lactamase of Klebsiella pneumoniae.

Project description:beta-Lactamase K1 was purified from Klebsiella pneumoniae SC10436. It is very similar to the enzyme produced by Klebsiella aerogenes 1082E and described by Emanuel, Gagnon & Waley [Biochem. J. (1986) 234, 343-347]. An active-site peptide was isolated after labelling of the enzyme with tritiated beta-iodopenicillanate. A cysteine residue was found just before the active-site serine residue. This result could explain the properties of the enzyme after modification by thiol-blocking reagents. The sequence of the active-site peptide clearly established the enzyme as a class A beta-lactamase.

Outbreak of CTX-M-15 Extended-Spectrum β-Lactamase-Producing Klebsiella pneumoniae ST394 in a French Intensive Care Unit Dedicated to COVID-19.

Project description:Infections caused by extended-spectrum β-lactamase-producing Klebsiella pneumoniae (ESBL-KP) are constantly rising worldwide and are often reported as causative agent of outbreaks in intensive care units (ICUs). During the first wave of the COVID-19 pandemic, bacterial cross-transmission was thought unlikely to occur due to the reinforcement of hygiene measures and prevention control. However, we report here an ESBL-producing K. pneumoniae (ST394) isolate responsible for a nosocomial outbreak in an ICU dedicated to COVID-19 patients.

Human pandemic K27-ST392 CTX-M-15 extended-spectrum β-lactamase-positive <i>Klebsiella pneumoniae</i>: A one health clone threatening companion animals.

Project description:Extended spectrum β-lactamase (ESBL)-producing Klebsiella pneumoniae is a medically important pathogen that commonly causes human nosocomial infections. Since veterinary emergency and critical care services have also significantly progressed over the last decades, there are increasing reports of ESBL-producing K. pneumoniae causing hospital-associated infections in companion animals. We present microbiological and genomic analysis of a multidrug-resistant ESBL-positive K. pneumoniae (LCKp01) isolated from a fatal infection in a dog admitted to a veterinary intensive care unit. LCKp01 strain belonged to the sequence type ST392 and displays a KL27 (wzi-187) and O-locus 4 (O4). A broad resistome and presence of the bla CTX-M-15 ESBL gene were predicted. SNP-based phylogenomic analysis, using an international genome database, clustered LCKp01 (60-80 SNPs differences) with K. pneumoniae ST392 from human and animal infections, isolated at 4-year interval, whereas phylogeographical analysis confirmed successful expansion of ST392 as a global clone of One Health concern.

Emergence of multidrug-resistant Klebsiella pneumoniae isolates producing VIM-4 metallo-beta-lactamase, CTX-M-15 extended-spectrum beta-lactamase, and CMY-4 AmpC beta-lactamase in a Tunisian university hospital.

Project description:Klebsiella pneumoniae clinical isolates resistant to carbapenems were recovered from 11 patients in the hospital of Sfax, Tunisia. The isolates were closely related as shown by pulsed-field gel electrophoresis, and they produced VIM-4 metallo-enzyme, CTX-M-15 extended-spectrum beta-lactamase, and CMY-4 AmpC enzyme. The bla(VIM-4) gene is part of a class 1 integron.

CTX-M-15 extended-spectrum ?-lactamase in a shiga toxin-producing Escherichia coli isolate of serotype O111:H8.

Project description:We report the discovery of a CTX-M-15-producing Escherichia coli (STEC) of serogroup O111:H8, a major serotype responsible for human enterohemorrhagic Escherichia coli (EHEC) infections. In line with the recent CTX-M-15/O104:H4 E. coli outbreak, these data may reflect an accelerating spread of resistance to expanded-spectrum cephalosporins within the E. coli population, including STEC isolates.
