Co-occurrence of triple carbapenemase genes, blaVIM-2, blaNDM-1, and blaOXA-48 in Enterobacter hormaechei clinical isolates -first report from Croatia.

Two Enterobacter hormaechei isolates harbouring three carbapenemase genes each, were isolated from two patients from different ICUs at University Hospital Centre Zagreb, Croatia, which is to our knowledge, the first report of triple carbapenemase (blaVIM-2, blaNDM-1, and blaOXA-48) co-existence in E. hormachei strains and also among Enterobacterales members in Croatia. Antimicrobial susceptibility testing showed susceptibility only to colistin and amikacin. The production of carbapenemases was phenotypically tested by immunochromatographic assay and confirmed by PCR. Detailed analysis by Whole Genome Sequencing (WGS) of short reads by Illumina and long reads by Oxford Nanopore Technologies (ONT) was additionally performed and showed that both isolates belonged to ST200. They were separated by 98 Single Nucleotide Polymorphisms (SNPs) having variations in the number of blaVIM-2 genes on the chromosome, the number of blaNDM-1 genes on the plasmid, non-identical blaNDM-1 plasmids, different plasmid content in general, and only one isolate carried a 94 kb prophage.

Vancomycin-sensitive Enterococcus faecium bacteraemia - hospital transmission and mortality in a Danish University Hospital.

Introduction. The emergence of vancomycin-resistant Enterococcus faecium (VREfm) has left the vancomycin-sensitive E. faecium (VSEfm) strains almost unnoticed.Hypothesis. Molecular characteristics, hospital transmission patterns and clinical impact of VSEfm have changed, and VSEfm is a predictor of VREfm introduction.Aim. We wanted to do a molecular characterization of VSEfm to identify hospital transmissions and links between VSEfm and VREfm, and to investigate the demographics, treatment and impact on mortality of VSEfm bacteraemia.Methodology. VSEfm and VREfm blood culture isolates from Odense University Hospital, Denmark, from 2015 to 2019 were characterized using whole-genome sequencing and core-genome multilocus sequence typing (cgMLST). Clonal shifts and diversity of the VREfm isolates were compared to the VSEfm isolates. Hospital records were used for clinical data and transmission investigation of VSEfm cases.Results. Six-hundred and thirty VSEfm isolates from 599 patients belonged to 42 sequence types (STs) and 131 complex types (CTs) in several clusters. Multiple types were involved in putative transmission, occurring over the entire period. Twenty-seven VREfm bacteraemia cases were included. No correlation between the VSEfm and VREfm clones was identified. The 30 day mortality was 40 %, but only in 6.3 % of the cases, VSEfm bacteraemia was the likely cause of death.Conclusion. The molecular types of VSEfm bacteraemia isolates are changing and diverse. No direct correlation between VSEfm and the introduction of VREfm was found, but widespread hospital transmission indicates a presence of risk factors that could facilitate transmission of other micro-organisms as well. VSEfm bacteraemia is rarely the cause of death, indicating that 30 day mortality does not reflect the cause of death.

Characterisation of carbapenemase-producing Acinetobacter baumannii isolates from danish patients 2014-2021: detection of a new international clone - IC11.

OBJECTIVES: This study aimed to characterise carbapenemase-producing Acinetobacter baumannii (A. baumannii) isolates from Danish patients using whole genome sequencing (WGS). It also compared typing and epidemiological data for further investigation of the spread and origin of the carbapenemase-producing A. baumannii isolates. METHODS: From 1 January 2014 to 30 September 2021, 141 carbapenemase-producing A. baumannii isolates, received at the national reference laboratory at Statens Serum Institut, were investigated using WGS. Multilocus sequence typing (MLST) and cgMLST data, obtained by SeqSphere+ software, were linked to data related to source of isolation, patient age and sex, hospital admission and travel history. RESULTS: Most of the carbapenemase-producing A. baumannii isolates were from males (n = 100, 71%). Most patients (n = 88, 63%) had travelled outside Scandinavia before admission to a Danish hospital. The most prevalent carbapenemase gene was blaOXA-23 (n = 124). Isolates belonging to the dominating international clone IC2 accounted for 78% of all isolates. A new international ST164/OXA-91 clone, proposed to be named IC11, was recognised and described. The cgMLST analysis revealed 17 clusters, reflecting both sporadic travel to similar geographical areas and confirmed outbreaks in Danish hospitals. CONCLUSIONS: The occurrence of carbapenemase-producing A. baumannii in Denmark was still low; however, isolates belonging to major international clones with a high potential to spread within hospitals, mainly IC2, dominated. OXA-23 was by far the most prevalent carbapenemase detected. Sporadic and travel-related introductions to Danish hospitals, also intra-hospital transmission, could be confirmed, emphasising the need for continuing vigilance.

Contaminated dicloxacillin capsules as the source of an NDM-5/OXA-48-producing Enterobacter hormaechei ST79 outbreak, Denmark and Iceland, 2022 and 2023.

From October 2022 through January 2023, nine patients with NDM-5/OXA-48-carbapenemase-producing Enterobacter hormaechei ST79 were detected in Denmark and subsequently one patient in Iceland. There were no nosocomial links between patients, but they had all been treated with dicloxacillin capsules. An NDM-5/OXA-48-carbapenemase-producing E. hormaechei ST79, identical to patient isolates, was cultured from the surface of dicloxacillin capsules in Denmark, strongly implicating them as the source of the outbreak. Special attention is required to detect the outbreak strain in the microbiology laboratory.

Synergy between Mecillinam and Ceftazidime/Avibactam or Avibactam against Multi-Drug-Resistant Carbapenemase-Producing Escherichia coli and Klebsiella pneumoniae.

Background: Carbapenemase-producing Klebsiella pneumoniae and Escherichia coli have become a significant global health challenge. This has created an urgent need for new treatment modalities. We evaluated the efficacy of mecillinam in combination with either avibactam or ceftazidime/avibactam against carbapenemase-producing clinical isolates. Materials and methods: Nineteen MDR clinical isolates of K. pneumoniae and E. coli were selected for the presence of blaKPC, blaNDM, blaOXA or blaIMP based on whole-genome sequencing and phenotypic susceptibility testing. We tested the synergy between mecillinam and avibactam or ceftazidime/avibactam. We used time−kill studies in vitro and a mouse peritonitis/sepsis model to confirm the synergistic effect. We investigated avibactam's impact on mecillinam´s affinity for penicillin-binding proteins with a Bocillin assay, and cell changes with phase-contrast and confocal laser scanning microscopy. Results: Mecillinam combined with ceftazidime/avibactam or avibactam substantially reduced MICs (from up to >256 µg/mL to <0.0016 µg/mL) for 17/18 strains. Significant log-CFU reductions were confirmed in time−kill and in vivo experiments. The Bocillin assay did not reveal changes. Conclusion: Mecillinam in combination with avibactam or ceftazidime/avibactam has a notable effect on most types of CPEs, both in vitro and in vivo. The mecillinam/avibactam combination treatment could be a new efficient antibiotic treatment against multi-drug-resistant carbapenemase-producing Gram-negative pathogens.

A case of blaNDM-1-positive Salmonella Kottbus, Denmark, November 2020.

We present a case of carbapenemase-producing blaNDM-1-positive Salmonella Kottbus in an 82-year-old Danish man. The blaNDM-1 was also identified in Escherichia coli and Citrobacter freundii in the same patient on the same 43 kb IncN2 plasmid, suggesting in vivo inter-species plasmid transfer. A NCBI BLAST analysis of the plasmid (pAMA003584_NDM-1) identified 12 highly similar plasmids, all originating from east and south-east Asia. This case could be the first confirmed case of blaNDM-1-positive Salmonella not related to travel outside Europe.

Lenient rate control versus strict rate control for atrial fibrillation: a protocol for the Danish Atrial Fibrillation (DanAF) randomised clinical trial.

INTRODUCTION: Atrial fibrillation is the most common heart arrhythmia with a prevalence of approximately 2% in the western world. Atrial fibrillation is associated with an increased risk of death and morbidity. In many patients, a rate control strategy is recommended. The optimal heart rate target is disputed despite the results of the the RAte Control Efficacy in permanent atrial fibrillation: a comparison between lenient vs strict rate control II (RACE II) trial.Our primary objective will be to investigate the effect of lenient rate control strategy (<110 beats per minute (bpm) at rest) compared with strict rate control strategy (<80 bpm at rest) on quality of life in patients with persistent or permanent atrial fibrillation. METHODS AND ANALYSIS: We plan a two-group, superiority randomised clinical trial. 350 outpatients with persistent or permanent atrial fibrillation will be recruited from four hospitals, across three regions in Denmark. Participants will be randomised 1:1 to a lenient medical rate control strategy (<110 bpm at rest) or a strict medical rate control strategy (<80 bpm at rest). The recruitment phase is planned to be 2 years with 3 years of follow-up. Recruitment is expected to start in January 2021. The primary outcome will be quality of life using the Short Form-36 (SF-36) questionnaire (physical component score). Secondary outcomes will be days alive outside hospital, symptom control using the Atrial Fibrillation Effect on Quality of Life, quality of life using the SF-36 questionnaire (mental component score) and serious adverse events. The primary assessment time point for all outcomes will be 1 year after randomisation. ETHICS AND DISSEMINATION: Ethics approval was obtained through the ethics committee in Region Zealand. The design and findings will be published in peer-reviewed journals as well as be made available on ClinicalTrials.gov. TRIAL REGISTRATION NUMBER: NCT04542785.

Herpes Simplex Virus Type 1 Pneumonia-A Review.

BACKGROUND: Pneumonia due to herpes simplex virus (HSV) is uncommon but can be seen in immunocompromised patients and has been associated with poor prognosis in this population. AIM: The aim was to study the results, outcome and mortality of HSV pneumonia in immunocompromised patients and patients receiving mechanical ventilation. Furthermore, it has been unclear whether to initiate prophylactic treatment with acyclovir or not. METHODS: We have conducted a literature search using the keywords herpes simplex pneumonia, critically ill patients and intensive care unit for identification of relevant publications. FINDINGS: HSV pneumonia can cause severe infection or even death in immunocompromised patients and critically ill patients. A clear diagnosis of HSV pneumonia can be difficult to establish. Respiratory condition may improve after initiation of acyclovir but data is scarce. CONCLUSION: HSV pneumonia should be considered in the immunocompromised patient and/or the intensive care patient who continues to deteriorate despite appropriate treatment. The value of prophylactic treatment with acyclovir is unproven but should be considered.

A Unified Approach to Local Quantum Uncertainty and Interferometric Power by Metric Adjusted Skew Information.

Local quantum uncertainty and interferometric power were introduced by Girolami et al. as geometric quantifiers of quantum correlations. The aim of the present paper is to discuss their properties in a unified manner by means of the metric adjusted skew information defined by Hansen.

Beneficial and harmful effects of sacubitril/valsartan in patients with heart failure: a systematic review of randomised clinical trials with meta-analysis and trial sequential analysis.

Current guidelines recommend angiotensin receptor blocker neprilysin inhibitors (ARNI) (sacubitril/valsartan) as a replacement for angiotensin-converting-enzymeinhibitor (ACE-I) in heart failure with reduced ejection fraction (HFrEF) who remain symptomatic despite optimal medical therapy. The effects of ARNIs have not previously been assessed in a systematic review. We searched for relevant trials until October 2019 in CENTRAL, MEDLINE, Embase, LILACS, BIOSIS, CNKI, VIP, WanFang and CBM. Our primary outcomes were all-cause mortality and serious adverse events. We systematically assessed the risks of random errors and systematic errors. PROSPERO registration: CRD42019129336. 48 trials randomising 19 086 participants were included. The ARNI assessed in all trials was sacubitril/valsartan. ACE-I or ARB were used as control interventions. Trials randomising HFrEF participants (27 trials) and heart failure with preserved ejection fraction (HFpEF) participants (four trials) were analysed separately. In HFrEF participants, meta-analyses and Trial Sequential Analyses showed evidence of a beneficial effect of sacubitril/valsartan when assessing all-cause mortality (risk ratio (RR), 0.86; 95% CI, 0.79 to 0.94) and serious adverse events (RR, 0.89; 95% CI, 0.86 to 0.93); and the results did not differ between the guideline recommended target population and HFrEF participants in general. We found no evidence of an effect of sacubitril/valsartan in HFpEF participants. Sacubitril/valsartan compared with either ACE-I or ARB seems to have a beneficial effect in patients with HFrEF. Our results indicate that sacubitril/valsartan might be beneficial in a wider population of patients with heart failure than the guideline recommended target population. Sacubitril/valsartan does not seem to show evidence of a difference compared with valsartan in patients with HFpEF.

Left Ventricular Mass Assessment by 1- and 2-Dimensional Echocardiographic Methods in Hemodialysis Patients: Changes in Left Ventricular Volume Using Echocardiography Before and After a Hemodialysis Session.

RATIONALE & OBJECTIVE: Left ventricular (LV) mass (LVM) is a predictor of cardiovascular morbidity and mortality and commonly calculated using 1-dimensional (1D) echocardiographic methods. These methods are vulnerable to small measurement errors and LVM may wrongly change according to changes in LV volume (LVV). Less commonly used 2-dimensional (2D) methods can accommodate to the changes in LVV and may be a better alternative among patients receiving hemodialysis (HD) with large fluid fluctuations. STUDY DESIGN: Observational study. SETTING & PARTICIPANTS: Patients with end-stage kidney disease receiving HD. EXPOSURE: One HD session. ANALYTICAL APPROACH: Transthoracic echocardiography was performed right before and after HD. LVM was calculated using 1D (Devereux, Penn, and Teichholz) and 2D methods (truncated ellipsoid and area-length). OUTCOMES: Significant differences in LVM after HD. RESULTS: We compared dimensions, LVV and LVM, in 53 patients (mean age, 63 ± 15 years; 66% men). For each 1-L increase in ultrafiltration volume (UFV), LV internal diameter decreased 1.1 mm (95% CI, 0.5-1.7 mm; P = 0.001). Patients were divided into 2 groups by the median UFV of 1.6 L. Patients with UFV > 1.6 L had significant smaller LVV and LV internal diameter after HD. LVM calculated using 1D methods decreased according to changes in LVV. Conversely, LVM calculated using 2D methods was not significantly different after HD. No significant change in differences between diastolic - systolic myocardial thickness or LVM as assessed using 1D and 2D methods was observed before and after HD, indicating that LVM remained constant despite HD. LIMITATIONS: We did not use contrast enhancement, 3-dimensional methods, or cardiac magnetic resonance. CONCLUSIONS: LVM calculated using 2D methods, truncated ellipsoid and area-length, is less affected by fluctuations in fluid and LVV, in contrast to 1D methods. Complementary LVM calculation using 2D methods is encouraged, especially in patients with large fluid fluctuations in which increased LVM using a 1D method has been detected.

Characterisation of extended-spectrum ß-lactamase/plasmid AmpC-ß-lactamase-producing Escherichia coli isolates from long-term recurrent bloodstream infections.

The aim of this study was to investigate recurrent infections in individual patients caused by extended-spectrum ß-lactamase and plasmid AmpC ß-lactamase-producing Escherichia coli (ESBL/pAmpC-Ec) isolates with >12-month interval. The Danish national collection of ESBL/pAmpC-Ec isolates collected from January 2014 through June 2017 was screened for patients with multiple isolates with >12 months between the episodes. Isolates underwent whole-genome sequencing and were analysed for antimicrobial resistance genes, virulence genes and multilocus sequence typing (MLST). Isolates were subtyped by core genome MLST (cgMLST) and CH typing. From a total of 970 patients, 15 unrelated patients experienced recurrent infections with ESBL/pAmpC-Ec. Of the 15 patients, 10 (67%) were found to be infected a second or third time with a genetically identical or similar strain. The resistance and virulence properties of the strains were similar in individual patients, however they were quite diverse when comparing between patients. Recurrent ESBL/pAmpC-Ec bloodstream infections of genetically related strains occurring with >12-month interval might be related to the previous episode and to a lesser extent be caused by re-infection. With >1000 days between the first and second episode of genetically similar strains (four allele differences), the recurrent infection is likely due to long-term host colonisation by ESBL/pAmpC-Ec. From this analysis, strains able to cause such recurrent infection were relatively diverse between patients. Knowledge about host and strain factors influencing such recurrent infections is needed to implement preventive measures.

Molecular characterization of Danish ESBL/AmpC-producing Klebsiella pneumoniae from bloodstream infections, 2018.

OBJECTIVES: The aim of the study was to molecularly characterize third-generation cephalosporin-resistant Klebsiella pneumoniae isolated from bloodstream infections in Denmark in 2018 using whole-genome sequencing (WGS) data, and to compare these isolates to the most common clones detected in 2006 and 2008. METHODS: Sixty-two extended-spectrum beta-lactamase (ESBL)/AmpC-producing K. pneumoniae isolates from Danish blood cultures from 2018 were analysed using WGS to obtain multilocus sequence typing (MLST), core genome MLST (cgMLST), resistance profile and phylogeny. These were compared to the most common ESBL K. pneumoniae clones detected in 2006 and 2008. RESULTS: The most common ESBL clone was ST15 CTX-M-15, the DHA-1 enzyme was the most common in AmpC isolates, and the OXA-48-like group was the most common carbapenemase. Thirty-nine different sequence types (STs) were found, with the most frequent being ST14, ST15 and ST37, accounting for 24% of the isolates. The isolates were subdivided into 55 complex types (CTs) of which 49 were singletons, with the most frequent being ST14-CT2080. Two of the CTX-M-15-producing isolates from 2018 belonged to the ST15-CT105/CT3078 clone, which was first detected in 2006. CONCLUSIONS: The ESBL/AmpC K. pneumoniae isolates detected in Danish blood cultures belonged to many different types. No dominant clones were circulating in Danish hospitals, but the ST15-CT105/CT3078 CTX-M-15 K. pneumoniae clone was seen 13 years after its first detection.

Surveillance of OXA-244-producing Escherichia coli and epidemiologic investigation of cases, Denmark, January 2016 to August 2019.

BackgroundCarbapenemase-producing Escherichia coli are increasing worldwide. In recent years, an increase in OXA-244-producing E. coli isolates has been seen in the national surveillance of carbapenemase-producing organisms in Denmark.AimMolecular characterisation and epidemiological investigation of OXA-244-producing E. coli isolates from January 2016 to August 2019.MethodsFor the epidemiological investigation, data from the Danish National Patient Registry and the Danish register of civil registration were used together with data from phone interviews with patients. Isolates were characterised by analysing whole genome sequences for resistance genes, MLST and core genome MLST (cgMLST).ResultsIn total, 24 OXA-244-producing E. coli isolates were obtained from 23 patients. Among the 23 patients, 13 reported travelling before detection of the E. coli isolates, with seven having visited countries in Northern Africa. Fifteen isolates also carried an extended-spectrum beta-lactamase gene and one had a plasmid-encoded AmpC gene. The most common detected sequence type (ST) was ST38, followed by ST69, ST167, ST10, ST361 and ST3268. Three clonal clusters were detected by cgMLST, but none of these clusters seemed to reflect nosocomial transmission in Denmark.ConclusionImport of OXA-244 E. coli isolates from travelling abroad seems likely for the majority of cases. Community sources were also possible, as many of the patients had no history of hospitalisation and many of the E. coli isolates belonged to STs that are present in the community. It was not possible to point at a single country or a community source as risk factor for acquiring OXA-244-producing E. coli.

Emergence of Enteroaggregative Escherichia coli within the ST131 Lineage as a Cause of Extraintestinal Infections.

Escherichia coli sequence type 131 (ST131) is a major cause of urinary and bloodstream infections. Its association with extended-spectrum ß-lactamases (ESBLs) significantly complicates treatment. Its best-described component is the rapidly expanding H30Rx clade, containing allele 30 of the type 1 fimbrial adhesin gene fimH This lineage appears to have emerged in the United States and spread around the world in part due to the acquisition of the ESBL-encoding blaCTX-M-15 gene and resistance to fluoroquinolones. However, non-H30 ST131 sublineages with other acquired CTX-M-type resistance genes are also emerging. Based on whole-genome analyses, we describe here the presence of an (fimH) H27 E. coli ST131 sublineage that has recently caused an outbreak of community-acquired bacteremia and recurrent urinary tract infections (UTIs) in Denmark. This sublineage has acquired both a virulence plasmid (pAA) that defines the enteroaggregative E. coli (EAEC) diarrheagenic pathotype and multiple genes associated with extraintestinal E. coli (ExPEC); combined, these traits have made this particular ST131 sublineage successful at colonizing its human host and causing recurrent UTI. Moreover, using a historic World Health Organization (WHO) E. coli collection and publicly available genome sequences, we identified a global H27 EAEC ST131 sublineage that dates back as far as 1998. Most H27 EAEC ST131 isolates harbor pAA or pAA-like plasmids, and our analysis strongly implies a single ancestral acquisition among these isolates. These findings illustrate both the profound plasticity of this important pathogenic E. coli ST131 H27 sublineage and genetic acquisitions of EAEC-specific virulence traits that likely confer an enhanced ability to cause intestinal colonization.IMPORTANCEE. coli ST131 is an important extraintestinal pathogenic lineage. A signature characteristic of ST131 is its ability to asymptomatically colonize the gastrointestinal tract and then opportunistically cause extraintestinal infections, such as cystitis, pyelonephritis, and urosepsis. In this study, we identified an ST131 H27 sublineage that has acquired the enteroaggregative diarrheagenic phenotype, spread across multiple continents, and caused multiple outbreaks of community-acquired ESBL-associated bloodstream infections in Denmark. The strain's ability to both cause diarrhea and innocuously colonize the human gastrointestinal tract may facilitate its dissemination and establishment in the community.

Investigation of possible clonal transmission of carbapenemase-producing Klebsiella pneumoniae complex member isolates in Denmark using core genome MLST and National Patient Registry Data.

OBJECTIVES: The aim of this study was to identify clonally-related carbapenemase-producing Klebsiella pneumoniae complex members that could be involved in outbreaks among hospitalized patients in Denmark, and to identify possible epidemiological links. METHODS: From January 2014 to June 2018, 103 isolates belonging to the K. pneumoniae complex were collected from 102 patients. From the whole-genome sequencing (WGS) data, presence of genes encoding carbapenemase and multilocal sequence typing (MLST) data were extracted. Core genome MLST (cgMLST) cluster analysis was performed. Using data from the Danish National Patient Registry (DNPR) and reported travel history, presumptive outbreaks were investigated for possible epidemiological links. RESULTS: The most common detected carbapenemase gene was blaOXA-48, followed by blaNDM-1. The 103 K. pneumoniae complex isolates belonged to 47 sequence types (STs) and cgMLST subdivided the isolates into 80 different complex types. cgMLST identified 13 clusters with 2-4 isolates per cluster. For five of the 13 clusters, a direct link (the patients stayed at the same ward on the same day) could be detected between at least some of the patients. In two clusters, the patients resided simultaneously at the same hospital, but not the same ward. A possible link (same ward within 1-13 days) was detected for the patients in one cluster. For five clusters detected by cgMLST, no epidemiological link could be detected using data from DNPR. CONCLUSION: In this study, cgMLST combined with patient hospital admission data and travel information was found to be a reliable and detailed approach to detect possible clonal transmission of carbapenemase-producing K. pneumoniae complex members.

Medical pluralism in the aftermath of cancer: health seeking actions and cancer patients' shaping of trajectories to healing.

Improved treatment methods for cancer are increasing the number of survivals in Norway. In turn, the group of people struggling with late effects after the treatment is growing. Late effects could be physical, psychological or existential conditions caused by treatment or the experience of illness. This qualitative study explores health-seeking actions among nine Norwegian people with cancer, and how they shape their trajectories to healing. Various health-seeking actions were identified through content analysis, and categorized as conventional, CAM, self-care, religious coping and traditional healing. Medical pluralism particularly flourished in the aftermath of cancer. We found that the phenomenon is characterized by: 1) implementation of contradicting models of reality and making pragmatic choices, 2) continuity and change of health seeking actions, 3) medical pluralism as a process, and 4) increased use of CAM and self-care to improve health and well-being in situations where the conventional care system has few available treatment options. To support people with long-term conditions, we need to know how they choose and make sense of their health-seeking activities. We argue that trajectories to healing are dynamic and shaped by people making choices. This process could be understood in greater depth by applying the concept of medical landscapes.

Bacteremia and urogenital infection with Actinomyces urogenitalis following prolonged urinary retention.

A case of bacteremia with the fastidious bacteria Actinomyces urogenitalis following lengthy urinary retention is reported in a sixty-year-old man. In 2013, the first case of bacteremia due to A. urogenitalis was presented, secondary to a tubo-ovarian abscess following transvaginal oocyte retrieval. To the best of our knowledge, this is the first male bacteremic episode involving A. urogenitalis related to a urinary tract focus. The patient had no prior urogenital medical history. Extensive susceptibility testing was done on isolates from urinary and blood cultures. The organism exhibited fluoroquinolone resistance but was susceptible to most other antibiotics used in the treatment of urinary infections. Due to its unusual growth requirements infections with A. urogenitalis are most likely an underdiagnosed entity.

Taxonomic reassessment of the genus Pseudocitrobacter using whole genome sequencing: Pseudocitrobacter anthropi is a later heterotypic synonym of Pseudocitrobacter faecalis and description of Pseudocitrobacter vendiensis sp. nov.

The taxonomic status of all Pseudocitrobacter species was re-evaluated by comparative genomics based on whole genome sequencing. As a result, it is obvious that Pseudocitrobacter anthropi is a later heterotypic synonym of Pseudocitrobacter faecalis. In addition, genome-based analysis of strain CPO20170097T, isolated from a patient in northern Denmark was allocated to the genus Pseudocitrobacter. This strain showed significant genotypic and phenotypic differences from P. faecalis and it is proposed that this strain represents a novel species of the genus, for which the name Pseudocitrobacter vendiensis sp. nov. is proposed with the type strain CPO20170097T (=CCUG 73096T=LMG 31042T).
