جِین(Gene): A Co-Designed Smartphone App for Genetics Education and Empowerment in the Pakistani Community.

In the Pakistani/British Pakistani community in England it is quite common for people to marry close cousin relatives, which can increase the chances of certain genetic problems in their children. Families in these situations often have little knowledge of genetics and encounter difficulties accessing genetic counselling services and culturally appropriate genetics information is needed to support these families. We describe the co-design of a prototype culturally sensitive smart phone app with the British Pakistani community, to improve understanding of genetics and genetic services.

Iron-binding biomolecules in the soluble hepatic fraction of the northern pike (Esox lucius): two-dimensional chromatographic separation with mass spectrometry detection.

Iron plays vital roles in important biological processes in fish, but can be toxic in high concentrations. The information on metalloproteins that participate in maintenance of Fe homeostasis in an esocid fish, the northern pike, as an important freshwater bioindicator species, are rather scarce. The aim of this study was to identify main cytosolic constituents that sequester Fe in the northern pike liver. The method applied consisted of two-dimensional HPLC separation of Fe-binding biomolecules, based on anion-exchange followed by size-exclusion fractionation. Apparent molecular masses of two main Fe-metalloproteins isolated by this procedure were ~360 kDa and ~50 kDa, with the former having more acidic pI, and indicated presence of ferritin and hemoglobin, respectively. MALDI-TOF-MS provided confirmation of ferritin subunit with a m/z peak at 20.65 kDa, and hemoglobin with spectra containing main m/z peak at 16.1 kDa, and smaller peaks at 32.1, 48.2, and 7.95 kDa (single-charged Hb-monomer, dimer, and trimer, and double-charged monomer, respectively). LC-MS/MS with subsequent MASCOT database search confirmed the presence of Hb-β subunits and pointed to close relation between esocid and salmonid fishes. Further efforts should be directed towards optimization of the conditions for metalloprotein analysis by mass spectrometry, to extend the knowledge on intracellular metal-handling mechanisms.

Mediodorsal thalamus and ventral pallidum contribute to subcortical regulation of the default mode network

Humans and other animals readily transition from externally to internally focused attention, and these transitions are accompanied by activation of the default mode network (DMN). The DMN was considered a cortical network, yet recent evidence suggests subcortical structures are also involved. We investigated the role of ventral pallidum (VP) and mediodorsal thalamus (MD) in DMN regulation in tree shrew, a close relative of primates. Electrophysiology and deep learning-based classification of behavioral states revealed gamma oscillations in VP and MD coordinated with gamma in anterior cingulate (AC) cortex during DMN states. Cross-frequency coupling between gamma and delta oscillations was higher during DMN than other behaviors, underscoring the engagement of MD, VP and AC. Our findings highlight the importance of VP and MD in DMN regulation, extend homologies in DMN regulation among mammals, and underline the importance of thalamus and basal forebrain to the regulation of DMN.

Family-Oriented Living Organ Donation in Bangladesh: A Bioethical Defence.

This study focuses on issues related to living organ donation for transplantation in Bangladesh. The policy and practice of living organ donation for transplantation in Bangladesh is family-oriented: close relatives (legal and genetic) are the only ones allowed to be living donors. Unrelated donors, altruistic donors (directed and non-directed), and paired/pooled or non-directed altruistic living donor chains-as many of these are implemented in other countries-are not legally allowed to serve as living donors in Bangladesh. This paper presents normative arguments explaining why the family-oriented nature of regulations and practices surrounding living organ donation for transplantation is essential for Bangladesh. In this article, I specifically argue that if the Bangladesh government revises the current biomedical policy robustly beyond relatives and allows unrelated donors to donate organs legally, this may foster organ selling due to the poverty and corruption problems in Bangladesh. The family-oriented requirement of the living organ donation policy and practice is defensible and morally justifiable as it preserves common notions of the family unit and family bonding in Bangladesh. Maintaining the current living-donation regulations and promoting deceased donation is the way forward, as this safely preserves the family values, protects against organ selling, and increases access to organ transplantation.

Gray mold disease on bottle gourd caused by Cladosporium tenuissimum in China.

Bottle gourd [Lagenaria siceraria (Mol.) Stand] is a widely cultivated succulent crop species. In December 2022, a serious bottle gourd disease occurred in the protected vegetable planting base of Xingguo County, Ganzhou City, Jiangxi Province, China, with 85% of the 2,100 plants having gray mold disease-like symptoms, including gray spots on the infected fruit. They quickly expanded at suitable temperature and humidity, forming a gray mold layer with inward depressions, which spread to the fruit stem causing watery rot, and the flesh turned black and started to rot. To isolate the pathogen, fruits of the diseased plants were surface-disinfected with 75% ethanol for 30 s, immersed in 0.1% HgCl2 for 1min, rinsed thrice with sterile water, and cultured on a potato-dextrose agar (PDA) medium at 28°C. Mycelia from the diseased tissue were subcultured on fresh PDA medium to obtain pure cultures. After incubation at 25°C for 7 days, olive-green colonies (~2.5mm·d-1) developed. Cultures developed numerous elliptical and limoniform conidia measuring 2.69~9.79 μm to 2.10~5.92 μm (average 5.62×3.12 μm) (n=20). The morphological characteristics of the pathogen resembled those of Cladosporium spp. Fungal genomic DNA was extracted, and the internal transcribed spacer (ITS), partial translation elongation factor-1 alpha (TEF-1α), and actin (ACT) regions were amplified with primers ITS1/4, TEF-728F/986R, and ACT-512F/783R, respectively, and sequenced (Bensch et al. 2012; Jo et al. 2018). Basic Local Alignment Search Tool analysis (BLAST) revealed that the ITS (accession no. OQ186729), ACT (OQ240962), and TEF-1α (OQ240963) sequences of isolate hjt4 shared the highest similarity (99-100%) with those of Cladosporium tenuissimum (accessions no. OM232068, OM256530, OM256526) (Duccio et al. 2015). A phylogenetic tree of the isolate hjt4 and its close relatives within Cladosporium was constructed using the MEGA X neighbor-joining method. The pathogen was identified as C. tenuissimum based on morphological and molecular characteristics. A specimen (JXAU-H2022982) was deposited at the Herbarium of the College of Agronomy, Jiangxi Agricultural University. To confirm its pathogenicity, seven-day-old healthy bottle gourd fruits were disinfected with 75% ethanol, 1 mm-deep wounds were made with sterilized scalpels, and the plants were inoculated with PDA plugs (0.8 cm in diameter) containing actively growing mycelia of isolate hjt4. Plants inoculated with sterile PDA plugs served as controls. Each group contained three fruits, and the experiment was performed in triplicate. All fruits were incubated in a biochemical incubator at 28°C. After 3 days, the fruit surface shrank, and the flesh turned to a black colour and rotten, which rapidly spread to the branches. Control fruits did not develop any symptoms. Reisolated colonies showed the same morphological traits as those of the inoculation isolates, whereas no target colonies were isolated from the control fruits. The pathogen was previously reported to cause leaf blight disease in Coriandrum sativum (Zhou et al. 2022) and sooty spots on Cape gooseberry (Miyake et al. 2022), among others. To our knowledge, this is the first report of gray mold disease caused by C. tenuissimum on bottle gourd in China. The findings provide an important foundation for monitoring and controlling the spread of this disease.

Relatives’ experiences of quality of healthcare services for adults with profound intellectual and multiple disabilities in Sweden

ABSTRACT Introduction There is little research regarding quality of health care for people with profound intellectual and multiple disabilities (PIMD), who often are represented by their relatives, because of their limited communication. The aim of this study was to explore experiences and perspectives of relatives regarding healthcare services for adults with PIMD. Method Twelve semi-structured telephone interviews were conducted involving close relatives of people with PIMD: mothers (n = 7), fathers (n = 2), brothers (n = 2) and a sister (n = 1). Qualitative content analysis was used. Results Three themes emerged from the material: (1) Holistic view and responsibility, (2) Complexity and specialisation require coordination, and (3) Specific knowledge about the individual with PIMD. Conclusions The relatives experienced that quality of health care should be based on a holistic view incorporating special competence and coordination. They emphasised the importance of an alliance, leveraging the relatives’ person-specific knowledge alongside healthcare professionals’ specialist competence.

Phylogenetic relationships and genetic diversity of the Korean endemic Phedimus latiovalifolius (Crassulaceae) and its close relatives

Phedimus latiovalifolius (Y.N.Lee) D.C.Son & H.J.Kim is exclusively distributed in the high mountains in the Korean Peninsula, mainly along the Baekdudaegan mountain range. Despite its morphological and distributional distinction from other Phedimus Raf. species, its taxonomic identity and phylogenetic relationship with congeneric species remain unclear. This study employs genotyping-by-sequencing-derived genome-wide single nucleotide polymorphisms to establish the monophyly of P. latiovalifolius and its relationship with closely related species. Genetic diversity and population differentiation of P. latiovalifolius are also assessed to provide baseline genetic information for future conservation and management strategies. Our phylogenetic analyses robustly demonstrate the monophyletic nature of P. latiovalifolius, with P. aizoon (L.) ‘t Hart identified as its closest sister lineage. There is no genetic evidence supporting a hybrid origin of P. latiovalifolius from P. aizoon involving either P. ellacombeanus (Praeger) ‘t Hart or P. kamtschaticus (Fisch.) ‘t Hart. Population genetic analyses reveal two major groups within P. latiovalifolius. A higher genetic variation is observed in P. ellacombeanus than in the congeneric species. Notably, most of the genetic variation exists within P. latiovalifolius populations. Given its distribution and the potential role of Baekdudaegan as an East Asian Pleistocene refugia, P. latiovalifolius could be considered rare and endemic, persisting in the refugium across glacial/interglacial cycles.

Ectodermal dysplasia and cholesteatoma: A cross-sectional analysis of otologic issues

ObjectivesPrevious studies have also associated cleft palate with increased cholesteatoma risk. Despite this close relation, the incidence of cholesteatoma and associated otologic issues in patients with ectodermal dysplasia types highly associated with cleft palate (EDT-ACPs) has not been formally analyzed. This study provides insight to guide clinicians caring for patients with ED types associated with cleft palate. MethodsIndividuals with TP63 disorders and Goltz syndrome/Focal Dermal Hypoplasia in the National Foundation for Ectodermal Dysplasia database were contacted for participation in an online REDCap survey from Sept–Dec ‘22. Descriptive statistics were generated using SAS JMP Pro 17 statistical software. Results65 individuals participated in the survey (response rate approx. 18 %). The median [IQR] age was 22 [14, 43], 41 (63 %) were female, and Ectrodactyly-Ectodermal Dysplasia-Cleft Lip/Palate Syndrome (EEC) was most common (n = 26, 40 %). We found that, among our respondents with a history of cleft palate, the incidence of cholesteatoma was 39 %. Among respondents without a history of cleft palate, the incidence of cholesteatoma was 13 % ConclusionsOtologic issues, such as cholesteatoma, can have permanent implications including hearing loss that can be minimized by early identification and treatment. The estimated incidence of cholesteatoma among our participants is far above the estimated incidence of cholesteatoma in the general population with and without a history of cleft palate, suggesting an independent contribution of EDT-ACPs to the risk of cholesteatoma.

Expanding the Pseudomonas diversity of the wheat rhizosphere: four novel species antagonizing fungal phytopathogens and with plant-beneficial properties.

Plant-beneficial Pseudomonas bacteria hold the potential to be used as inoculants in agriculture to promote plant growth and health through various mechanisms. The discovery of new strains tailored to specific agricultural needs remains an open area of research. In this study, we report the isolation and characterization of four novel Pseudomonas species associated with the wheat rhizosphere. Comparative genomic analysis with all available Pseudomonas type strains revealed species-level differences, substantiated by both digital DNA-DNA hybridization and average nucleotide identity, underscoring their status as novel species. This was further validated by the phenotypic differences observed when compared to their closest relatives. Three of the novel species belong to the P. fluorescens species complex, with two representing a novel lineage in the Pseudomonas phylogeny. Functional genome annotation revealed the presence of specific features contributing to rhizosphere colonization, including flagella and components for biofilm formation. The novel species have the genetic potential to solubilize nutrients by acidifying the environment, releasing alkaline phosphatases and their metabolism of nitrogen species, indicating potential as biofertilizers. Additionally, the novel species possess traits that may facilitate direct promotion of plant growth through the modulation of the plant hormone balance, including the ACC deaminase enzyme and auxin metabolism. The presence of biosynthetic clusters for toxins such as hydrogen cyanide and non-ribosomal peptides suggests their ability to compete with other microorganisms, including plant pathogens. Direct inoculation of wheat roots significantly enhanced plant growth, with two strains doubling shoot biomass. Three of the strains effectively antagonized fungal phytopathogens (Thielaviopsis basicola, Fusarium oxysporum, and Botrytis cinerea), demonstrating their potential as biocontrol agents. Based on the observed genetic and phenotypic differences from closely related species, we propose the following names for the four novel species: Pseudomonas grandcourensis sp. nov., type strain DGS24T ( = DSM 117501T = CECT 31011T), Pseudomonas purpurea sp. nov., type strain DGS26T ( = DSM 117502T = CECT 31012T), Pseudomonas helvetica sp. nov., type strain DGS28T ( = DSM 117503T = CECT 31013T) and Pseudomonas aestiva sp. nov., type strain DGS32T ( = DSM 117504T = CECT 31014T).

GRAPPA 2023 Patient Research Partner (PRP) Network Update: Enhancing PRP Involvement Within GRAPPA.

Nine patient research partners (PRPs) attended the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting in person in Dublin, Ireland. The importance of close relations between researchers, clinicians, and PRPs was highlighted at the PRP premeeting, with discussion regarding PRP engagement within GRAPPA with the GRAPPA leadership team. A presentation was given by PRPs at the plenary session, and there was continued active engagement of PRPs in breakout sessions, workshops, and plenary sessions compared to previous annual meetings. The GRAPPA PRP Network is committed to supporting the GRAPPA mission and contributing the unique perspectives of dedicated, knowledgeable individuals with the lived experience of psoriatic disease. This report provides a summary of the GRAPPA PRP Network meetings at the GRAPPA 2023 annual meeting and the continued commitment of the GRAPPA PRP Network to enhance PRP involvement within GRAPPA activities.

Resolving the evolutionary history of Ctenium and Kampochloa using phylogenomics, and a new circumscription of Cteniinae (Cynodonteae, Poaceae)

AbstractCtenium has about 20 species distributed in Africa, Arabia, and the Neotropics, with no species occurring on more than one continent. Its relationship with the morphologically similar Kampochloa is still unclear and has not been investigated. In this study, we performed phylogenomic analyses using 71 protein‐coding genes of 24 newly sequenced plastomes, of 13 species of Ctenium and 1 species of Kampochloa to understand their biogeography and the phylogenetic and evolutionary relationships between these two genera and within Ctenium. Our results support two major clades of Ctenium: the Neotropics and Old‐World clades. Kampochloa is shown to be a close relative of the genus Ctenium, and their morphological similarities support this. Divergence time estimation analyses show that Kampochloa and Ctenium diverged around 7.99 Ma, and might have originated in the late Miocene during the rapid expansion of C4 grasslands. With this evidence from morphology and phylogenomic data, we propose the inclusion of the previously unplaced Kampochloa into the subtribe Cteniinae.

Highly Contiguous Genome Assembly of Drosophila prolongata - a Model for Evolution of Sexual Dimorphism and Male-specific Innovations.

Drosophila prolongata is a member of the melanogaster species group and rhopaloa subgroup native to the subtropical highlands of southeast Asia. This species exhibits an array of recently evolved male-specific morphological, physiological, and behavioral traits that distinguish it from its closest relatives, making it an attractive model for studying the evolution of sexual dimorphism and testing theories of sexual selection. The lack of genomic resources has impeded the dissection of the molecular basis of sex-specific development and behavior in this species. To address this, we assembled the genome of D. prolongata using long-read sequencing and Hi-C scaffolding, resulting in a highly complete and contiguous (scaffold N50 2.2Mb) genome assembly of 220Mb. The repetitive content of the genome is 24.6%, the plurality of which are LTR retrotransposons (33.2%). Annotations based on RNA-seq data and homology to related species revealed a total of 19,330 genes, of which 16,170 are protein-coding. The assembly includes 98.5% of Diptera BUSCO genes, including 93.8% present as a single copy. Despite some likely regional duplications, the completeness of this genome suggests that it can be readily used for gene expression, GWAS, and other genomic analyses.

German Art of the 19th Century through the Lens of The Greek Literary Magazine Kleiō (Clio): Academic Formalism Versus Modernism

We examine the work of 19th-century German painters as presented in the Greek-language magazine Kleiō published in Germany in the late 19th century. Through an extensive catalogue of paintings, the article highlights the themes that preoccupied German painters during this period. It places particular emphasis on their approach, aesthetic preferences, the decisive role played by the Academies of Fine Arts, and their attitudes towards the modern movements developing in France during the 19th century. It explores the reasons for which Kleiō magazine promoted academic German painting to its Greek readership. It reports the particularly close relations between Greece and Germany during this period and the fact that many Greek painters completed their studies at the Munich Academy of Fine Arts. Since for most of the 19th century, Germany was deeply influenced by the achievements of ancient Greek art, many German painters opposed modernism, instead upholding what they perceived to be the values and ideals of classical antiquity integrating them into German art

Implications of HIV status disclosure

Disclosure of HIV status is critical for HIV prevention and control. However, although the benefits of HIV disclosure have received extensive documentation, the same cannot be said for its drawbacks. In the current study, we used a descriptive qualitative study design to highlight the implications of disclosure among 30 pregnant and postpartum women living with HIV in Uganda. We conducted a qualitative content analysis and found that healthcare professionals responded positively and supportively when HIV-positive pregnant and postpartum women disclosed their status, and that individuals who disclosed their status to their husbands but not to wider circles also experienced no mistreatment or discrimination. Contrarily, however, some husbands reacted unfavourably to their wife’s HIV-positive status when a larger audience was involved in the disclosure. In particular, we discovered that co-wives and in-laws promoted stigmatization, including violence, by husbands. The interaction between these HIV-positive women and their mothers also demonstrated both positive and negative implications. This counterintuitive attitude has the consequence of reducing the uptake of antiretroviral drugs. There is therefore a need for policies and initiatives that not only encourage disclosure to health professionals, spouses and a few close relatives or friends but prevent stigmatization, violence and other forms of abuse against HIV-positive women.

Core groups

The core group of a classical link was introduced independently by Kelly in 1991 and Wada in 1992. It is a link invariant defined by a presentation involving the arcs and crossings of a diagram, related to Wirtinger’s presentation of the fundamental group of a link complement. Two close relatives of the core group are defined by presentations involving regions rather than arcs; one of them is related to Dehn’s presentation of a link group. The definitions are extended to virtual link diagrams and properties of the resulting invariants are discussed.

Molecular detection of sub-microscopic infections and Plasmodium falciparum histidine-rich protein-2 and 3 gene deletions in pre-elimination settings of South Africa

South Africa’s efforts toward eliminating malaria have positioned the country in the pre-elimination stage. Imported and sub-microscopic cases still contribute to the persistence of malaria in regions of low transmission as identified in this study where diagnostics is built largely on the use of Rapid Diagnostic Test (RDT). However, the presence of Pfhrp2/3 gene deletion is known to interfere with the accuracy of diagnosis with the use of RDT. Malaria elimination and detection of Pfhrp2/3 gene deletion in the pre-elimination setting requires accurate molecular surveillance. With the core objective of this study being the determination of the presence sub-microscopic malaria cases and deleted Pfhrp2/3 gene markers, a total of 354 samples were collected from five districts of KwaZulu Natal, South Africa. These samples were prepared for molecular analysis using primers and PCR conditions specific for amplification of 18S rRNA and msp-1gene. Positive amplicons were analysed for the presence of Pfhrp2/3 and flanking genes, along with Sanger sequencing and phylogenetic studies. Out of 354 samples collected 339 were tested negative with PfHRP2 based RDTs. Of these Pfhrp2 and Pfhrp3 gene deletions were confirmed in 94.7% (18/19) and 100% (19/19) respectively. High migration rate (75%) among the study participants was noted and phylogenetic analysis of sequenced isolates showed close evolutionary relatedness with India, United Kingdom, Iran, and Myanmar and China isolates. Molecular-based test is recommended as an essential surveillance tool for malaria management programs as the target focuses on elimination.

A new geminialphasatellite associated with wheat dwarf virus identified in winter barley in France.

Using a high-throughput sequencing (HTS) approach, we report the discovery of a new alphasatellite identified in a winter barley plant collected in France in 2022 that was also infected by wheat dwarf virus (WDV). The presence of the satellite and of WDV was confirmed by several independent PCR assays, and the complete genome sequence was determined. The circular satellite genome is 1424 nt long and shows typical hallmarks of members of the subfamily Geminialphasatellitinae, including a replication-associated hairpin with a CAGTATTAC sequence and a Rep-encoding open reading frame (ORF). It also possesses a second ORF, embedded in a different frame within the Rep ORF, which is also observed in clecrusatellites and a few other members of the family Alphasatellitidae. Pairwise sequence comparisons and phylogenetic analysis showed that this satellite represents a novel species. Its closest relatives are in the genus Colecusatellite, but it likely represents a new genus given its divergence from other genera of the subfamily Geminialphasatellitinae. Given that WDV was the only virus observed in coinfection with the satellite, the name "wheat dwarf virus-associated alphasatellite" is proposed for this novel agent.

Dynamic Expansions and Retinal Expression of Spectrally Distinct Short-Wavelength Opsin Genes in Sea Snakes.

The photopigment-encoding visual opsin genes that mediate colour perception show great variation in copy number and adaptive function across vertebrates. An open question is how this variation has been shaped by the interaction of lineage-specific structural genomic architecture and ecological selection pressures. We contribute to this issue by investigating the expansion dynamics and expression of the duplicated Short-Wavelength-Sensitive-1 opsin (SWS1) in sea snakes (Elapidae). We generated one new genome, 45 resequencing datasets, 10 retinal transcriptomes, and 81 SWS1 exon sequences for sea snakes, and analysed these alongside 16 existing genomes for sea snakes and their terrestrial relatives. Our analyses revealed multiple independent transitions in SWS1 copy number in the marine Hydrophis clade, with at least three lineages having multiple intact SWS1 genes: the previously studied Hydrophis cyanocinctus and at least two close relatives of this species; H. atriceps-H. fasciatus; and an individual H. curtus. In each lineage, gene copy divergence at a key spectral tuning site resulted in distinct UV and Violet/Blue-sensitive SWS1 subtypes. Both spectral variants were simultaneously expressed in the retinae of H. cyanocinctus and H. atriceps, providing the first evidence that these SWS1 expansions confer novel phenotypes. Finally, chromosome annotation for nine species revealed shared structural features in proximity to SWS1 regardless of copy number. If these features are associated with SWS1 duplication, expanded opsin complements could be more common in snakes than is currently recognised. Alternatively, selection pressures specific to aquatic environments could favour improved chromatic distinction in just some lineages.

Russia’s Participation in the Development of Transport and Logistics Highways of the EAEU Member States

Aim. An overview analysis of the prospects for trade and economic relations in the EAEU, the SCO countries and other interested states, coupled with interests in the geo-economic and geopolitical Eurasian space in the conditions of artificial escalation of local tensions by the collective West.Tasks. Search and evaluation of optimal routes for the development of traditional and new transport and logistics highways, their branched corridors from the perspective of strengthening economic integration agreements, security and interaction of the Eurasian Union with the SCO countries.Methods. The article uses methodological tools of spatial economics, economic, geographical and geopolitical analysis of the interests of states, analysis and synthesis of interests and synergy of interests of the participating states of global Eurasian projects.Conclusions. The study showed the possibilities of new and old transport magistral (the highway) systems (TMS), both through Kazakhstan and through the development of a unique alternative — the Northern Sea Route (NSR) with the construction of a completely new infrastructure and their maintenance. The issues of TMS on the BAM and Trans-Siberian railway were touched upon. An assessment of alternatives to TMS in terms of cost and time is given. The potential opportunities of the expanding TMS and cargo traffic along the Caspian-Caspian corridor, both overland from the east (Turkmenistan — Kazakhstan — Russia) and the western shore of the Caspian Sea (Iran — Azerbaijan — Russia), as well as along waterways along the same “North — South” corridor, are indicated.Results. An assessment of effective routes has been carried out; strategic objectives have been identified for newly opened transport and logistics highways, which are defined as “new lye routes” through the territories of the EAEU and neighboring interested states (China, India, Pakistan, Afghanistan, Iran, etc.), which gradually plan to enter into closer relations from participating observers relations in the international division of labor.

Pseudomonas aeruginosa producing FIM-1-metallo-β-lactamase: emergence and cross-transmission in a long-term acute care rehabilitation hospital.

FIM-1 metallo-β-lactamase was previously detected in sporadic Pseudomonas aeruginosa clinical isolates. Here, we report on FIM-1-positive P. aeruginosa from two patients who had shared the same ward in a long-term acute care rehabilitation hospital. Whole-genome sequencing analysis revealed close relatedness of these isolates, which belonged to an ST235 sublineage (clade 8/14) different from those previously reported. Results highlighted the occurrence of clonal diversity among FIM-positive strains and the possibility of their cross-transmission in some healthcare settings.
