| 5703 | 0 | 0.8650 | Genetic determinants and phenotypic characteristics of heavy metal and biocide tolerance among multidrug-resistant and susceptible Gram-negative bacilli clinical isolates. Antimicrobial resistance is a major health care problem as well as a concern for global public health. As a result, the use of nonantibiotic antimicrobials, such as heavy metals and biocides, has increased in a bid to control the spread of antibiotic-resistant bacteria. Consequently, heavy metal tolerance genes (HMTGs) and biocide tolerance genes (BTGs) have been more frequently detected in Gram-negative bacilli. In this study, we searched for acquired HMTGs, BTGs, and antibiotic resistance genes (ARGs) and determined the MICs of common heavy metals and biocides in multidrug-resistant and susceptible Gram-negative bacilli clinical isolates. A high frequency of silA and pcoD genes was mainly detected among Klebsiella spp. and Enterobacter cloacae regardless of their susceptible profile. The merA gene was also found in isolates carrying silA/pcoD genes. ARGs were detected in isolates that harboured silA and/or pcoD genes. BTGs (qacΔE, ydgE, ydgF, mdfA, and emrE) were mostly detected in Klebsiella pneumoniae and E. cloacae isolates regardless of their susceptibility profile, and these isolates often co-harboured HMTGs and/or ARGs. Higher copper sulphate MIC values were obtained under aerobic conditions, regardless of the presence or absence of pcoD and/or silA genes. Nevertheless, in most isolates carrying pcoD/silA, higher copper sulphate MIC values were determined under anaerobic conditions. Regarding AgNO(3), no significant differences in MIC values were observed for isolates with or without the silA gene. Our results show a broad distribution of HMTGs, BTGs, and ARGs in bacteria causing health care-associated infections, which could contribute to the co-selection of hospital pathogens resistant to multiple and diverse antimicrobials. | 2025 | 39984044 |
| 1739 | 1 | 0.8586 | Antimicrobial-resistant Enterobacteriaceae from humans and wildlife in Dzanga-Sangha Protected Area, Central African Republic. Antimicrobial resistance is a worldwide concern of public health. Unfortunately, resistant bacteria are spreading to all ecosystems, including the strictly protected ones. We investigated antimicrobial resistance in gastrointestinal Enterobacteriaceae of wild mammals and people living within Dzangha-Sangha Protected Areas, Central African Republic, with an emphasis on extended-spectrum β-lactamase (ESBL) and plasmid-mediated quinolone resistance (PMQR) genes. We compare resistance genes found in microbiota of humans, gorillas habituated and unhabituated to humans and other wildlife. In gorillas, we additionally investigate the presence of ESBL resistant isolates after treatment by ceftiofur. We found a considerable prevalence of multiresistant Enterobacteriaceae isolates with ESBL and PMQR genes in humans (10% and 31%, respectively). Among wildlife the most significant findings were CTX-M-15-producing Klebsiella pneumoniae in a habituated gorilla and a multiresistant Escherichia coli isolate with gene qepA in an unhabituated gorilla. Other isolates from wildlife were mostly represented by qnrB-harboring Citrobacter spp. The relatedness of resistant E. coli was investigated in a PFGE-based dendrogram; isolates from gorillas showed less than 80% similarity to each other and less than 80% similarity to human isolates. No ESBL-producing isolates were found in animals treated by ceftiofur. Although we did not detect any bacterial clone common to wildlife and humans, we detected an intersection in the spectrum of resistance genes found in humans and gorillas, represented by blaCTX-M-15 and qepA. | 2014 | 24636162 |
| 2270 | 2 | 0.8582 | Antibiotic resistant bacteria and resistance genes in biofilms in clinical wastewater networks. Increasing isolation rates of resistant bacteria in the last years require identification of potential infection reservoirs in healthcare facilities. Especially the clinical wastewater network represents a potential source of antibiotic resistant bacteria. In this work, the siphons of the sanitary installations from 18 hospital rooms of two German hospitals were examined for antibiotic resistant bacteria and antibiotic residues including siphons of showers and washbasins and toilets in sanitary units of psychosomatic, haemato-oncological, and rehabilitation wards. In addition, in seven rooms of the haemato-oncological ward, the effect of 24 h of stagnation on the antibiotic concentrations and MDR (multi-drug-resistant) bacteria in biofilms was evaluated. Whereas no antibiotic residues were found in the psychosomatic ward, potential selective concentrations of piperacillin, meropenem and ciprofloxacin were detected at a rehabilitation ward and ciprofloxacin and trimethoprim were present at a haemato-oncology ward. Antibiotic resistant bacteria were isolated from the siphons of all wards, however in the psychosomatic ward, only one MDR strain with resistance to piperacillin, third generation cephalosporins and quinolones (3MRGN) was detected. In contrast, the other two wards yielded 11 carbapenemase producing MDR isolates and 15 3MRGN strains. The isolates from the haemato-oncological ward belonged mostly to two specific rare sequence types (ST) (P. aeruginosa ST823 and Enterobacter cloacae complex ST167). In conclusion, clinical wastewater systems represent a reservoir for multi-drug-resistant bacteria. Consequently, preventive and intervention measures should not start at the wastewater treatment in the treatment plant, but already in the immediate surroundings of the patient, in order to minimize the infection potential. | 2019 | 30905579 |
| 2493 | 3 | 0.8572 | Multidrug-resistant hypervirulent Klebsiella pneumoniae: an evolving superbug. Multidrug-resistant hypervirulent Klebsiella pneumoniae (MDR-hvKP) combines high pathogenicity with multidrug resistance to become a new superbug. MDR-hvKP reports continue to emerge, shattering the perception that hypervirulent K. pneumoniae (hvKP) strains are antibiotic sensitive. Patients infected with MDR-hvKP strains have been reported in Asia, particularly China. Although hvKP can acquire drug resistance genes, MDR-hvKP seems to be more easily transformed from classical K. pneumoniae (cKP), which has a strong gene uptake ability. To better understand the biology of MDR-hvKP, this review discusses the virulence factors, resistance mechanisms, formation pathways, and identification of MDR-hvKP. Given their destructive and transmissible potential, continued surveillance of these organisms and enhanced control measures should be prioritized. | 2025 | 40135944 |
| 1401 | 4 | 0.8571 | Molecular Surveillance of Multidrug-Resistant Bacteria among Refugees from Afghanistan in 2 US Military Hospitals during Operation Allies Refuge, 2021. In 2021, two US military hospitals, Landstuhl Regional Medical Center in Landstuhl, Germany, and Walter Reed National Military Medical Center (WRNMMC) in Bethesda, Maryland, USA, observed a high prevalence of multidrug-resistant bacteria among refugees evacuated from Afghanistan during Operation Allies Refuge. Multidrug-resistant isolates collected from 80 patients carried an array of antimicrobial resistance genes, including carbapenemases (bla(NDM-1), bla(NDM-5), and bla(OXA-23)) and 16S methyltransferases (rmtC and rmtF). Considering the rising transmission of antimicrobial resistance and unprecedented population displacement globally, these data are a reminder of the need for robust infection control measures and surveillance. | 2024 | 39530854 |
| 2491 | 5 | 0.8571 | Baicalein Inhibits Plasmid-Mediated Horizontal Transmission of the blaKPC Multidrug Resistance Gene from Klebsiella pneumoniae to Escherichia coli. Carbapenem-resistant bacterial infections pose an urgent threat to public health worldwide. Horizontal transmission of the β-lacatamase Klebsiella pneumoniae carbapenemase (blaKPC) multidrug resistance gene is a major mechanism for global dissemination of carbapenem resistance. Here, we investigated the effects of baicalein, an active ingredient of a Chinese herbal medicine, on plasmid-mediated horizontal transmission of blaKPC from a meropenem-resistant K. pneumoniae strain (JZ2157) to a meropenem-sensitive Escherichia coli strain (E600). Baicalein showed no direct effects on the growth of JZ2157 or E600. Co-cultivation of JZ2157 and E600 caused the spread of meropenem resistance from JZ2157 to E600. Baicalein at 40 and 400 µg/mL significantly inhibited the spread of meropenem resistance. Co-cultivation also resulted in plasmid-mediated transmission of blaKPC from JZ2157 to E600, which was inhibited by baicalein. Therefore, baicalein may be used in clinical practice to prevent or contain outbreaks of carbapenem-resistant infections by inhibiting the horizontal transfer of resistance genes across bacteria species. | 2023 | 36543225 |
| 2495 | 6 | 0.8570 | Transmission of Mobile Colistin Resistance (mcr-1) by Duodenoscope. BACKGROUND: Clinicians increasingly utilize polymyxins for treatment of serious infections caused by multidrug-resistant gram-negative bacteria. Emergence of plasmid-mediated, mobile colistin resistance genes creates potential for rapid spread of polymyxin resistance. We investigated the possible transmission of Klebsiella pneumoniae carrying mcr-1 via duodenoscope and report the first documented healthcare transmission of mcr-1-harboring bacteria in the United States. METHODS: A field investigation, including screening targeted high-risk groups, evaluation of the duodenoscope, and genome sequencing of isolated organisms, was conducted. The study site included a tertiary care academic health center in Boston, Massachusetts, and extended to community locations in New England. RESULTS: Two patients had highly related mcr-1-positive K. pneumoniae isolated from clinical cultures; a duodenoscope was the only identified epidemiological link. Screening tests for mcr-1 in 20 healthcare contacts and 2 household contacts were negative. Klebsiella pneumoniae and Escherichia coli were recovered from the duodenoscope; neither carried mcr-1. Evaluation of the duodenoscope identified intrusion of biomaterial under the sealed distal cap; devices were recalled to repair this defect. CONCLUSIONS: We identified transmission of mcr-1 in a United States acute care hospital that likely occurred via duodenoscope despite no identifiable breaches in reprocessing or infection control practices. Duodenoscope design flaws leading to transmission of multidrug-resistant organsisms persist despite recent initiatives to improve device safety. Reliable detection of colistin resistance is currently challenging for clinical laboratories, particularly given the absence of a US Food and Drug Administration-cleared test; improved clinical laboratory capacity for colistin susceptibility testing is needed to prevent the spread of mcr-carrying bacteria in healthcare settings. | 2019 | 30204838 |
| 2518 | 7 | 0.8568 | Plasmids Carrying Antimicrobial Resistance Genes in Gram-Negative Bacteria.

| 1719 | 8 | 0.8561 | Acquisition of Plasmid with Carbapenem-Resistance Gene bla(KPC2) in Hypervirulent Klebsiella pneumoniae, Singapore. The convergence of carbapenem-resistance and hypervirulence genes in Klebsiella pneumoniae has led to the emergence of highly drug-resistant superbugs capable of causing invasive disease. We analyzed 556 carbapenem-resistant K. pneumoniae isolates from patients in Singapore hospitals during 2010-2015 and discovered 18 isolates from 7 patients also harbored hypervirulence features. All isolates contained a closely related plasmid (pKPC2) harboring bla(KPC-2), a K. pneumoniae carbapenemase gene, and had a hypervirulent background of capsular serotypes K1, K2, and K20. In total, 5 of 7 first patient isolates were hypermucoviscous, and 6 were virulent in mice. The pKPC2 was highly transmissible and remarkably stable, maintained in bacteria within a patient with few changes for months in the absence of antimicrobial drug selection pressure. Intrapatient isolates were also able to acquire additional antimicrobial drug resistance genes when inside human bodies. Our results highlight the potential spread of carbapenem-resistant hypervirulent K. pneumoniae in Singapore. | 2020 | 32091354 |
| 1874 | 9 | 0.8561 | Potential sources and characteristic occurrence of mobile colistin resistance (mcr) gene-harbouring bacteria recovered from the poultry sector: a literature synthesis specific to high-income countries. Understanding the sources, prevalence, phenotypic and genotypic characteristics of mcr gene-harbouring bacteria (MGHB) in the poultry sector is crucial to supplement existing information. Through this, the plasmid-mediated colistin resistance (PMCR) could be tackled to improve food safety and reduce public health risks. Therefore, we conducted a literature synthesis of potential sources and characteristic occurrence of MGHB recovered from the poultry sector specific to the high-income countries (HICs). Colistin (COL) is a last-resort antibiotic used for treating deadly infections. For more than 60 years, COL has been used in the poultry sector globally, including the HICs. The emergence and rapid spread of mobile COL resistance (mcr) genes threaten the clinical use of COL. Currently, ten mcr genes (mcr-1 to mcr-10) have been described. By horizontal and vertical transfer, the mcr-1, mcr-2, mcr-3, mcr-4, mcr-5, and mcr-9 genes have disseminated in the poultry sector in HICs, thus posing a grave danger to animal and human health, as harboured by Escherichia coli, Klebsiella pneumoniae, Salmonella species, and Aeromonas isolates. Conjugative and non-conjugative plasmids are the major backbones for mcr in poultry isolates from HICs. The mcr-1, mcr-3 and mcr-9 have been integrated into the chromosome, making them persist among the clones. Transposons, insertion sequences (IS), especially ISApl1 located downstream and upstream of mcr, and integrons also drive the COL resistance in isolates recovered from the poultry sector in HICs. Genes coding multi-and extensive-drug resistance and virulence factors are often co-carried with mcr on chromosome and plasmids in poultry isolates. Transmission of mcr to/among poultry strains in HICs is clonally unrestricted. Additionally, the contact with poultry birds, manure, meat/egg, farmer's wears/farm equipment, consumption of contaminated poultry meat/egg and associated products, and trade of poultry-related products continue to serve as transmission routes of MGHB in HICs. Indeed, the policymakers, especially those involved in antimicrobial resistance and agricultural and poultry sector stakeholders-clinical microbiologists, farmers, veterinarians, occupational health clinicians and related specialists, consumers, and the general public will find this current literature synthesis very useful. | 2021 | 34707919 |
| 1718 | 10 | 0.8560 | Pandrug-resistant Klebsiella pneumoniae isolated from Ukrainian war victims are hypervirulent. OBJECTIVES: Carbapenem- and colistin-resistant Klebsiella pneumoniae were isolated from war victims treated in hospitals in Ukraine. The question was whether these pandrug-resistant K. pneumoniae are pathogenic and capable of causing disease in a broader context. METHODS: Klebsiella pneumoniae clinical isolates (n = 37) were tested for antibiotic resistance and subjected to whole-genome sequencing (WGS). In addition, their pathogenicity was tested by serum resistance and two separate animal models. RESULTS: Isolates belonging to the sequence types (ST) 23, 147, 307, 395, and 512 were found to harbor resistance genes against carbapenems and cephalosporins. Nine isolates carried point mutations in pmrB and phoP genes associated with colistin resistance. All bacteria were equipped with multiple virulence genes, and the colistin-resistant isolates each carried 10 different genes. Colistin-resistant K. pneumoniae were more serum-resistant, more virulent against G. mellonella larvae, and displayed an increased survival in mice compared to colistin-susceptible bacteria. The iucA, peg-344, rmpA, rmpC, and rmpD genes were associated with increased virulence in animals. CONCLUSIONS: Pandrug-resistant K. pneumoniae in Ukraine are hypervirulent and retain their pathogenicity, highlighting the need to prevent disseminated spread. | 2024 | 39396555 |
| 1549 | 11 | 0.8560 | Evaluation of the Inter- and Intrahospital Spread of Multidrug Resistant Gram-Negative Bacteria in Lithuanian Hospitals. Spread of multidrug-resistant pathogenic bacteria became one of the greatest threats in healthcare worldwide. It is generally accepted that both inter- and intrahospital transmissions of these bacteria contribute significantly to this problem. The purpose of the current study was the evaluation of the inter- and intrahospital spread of multidrug resistant Gram-negative pathogenic bacteria in Lithuania. Clinical isolates of Acinetobacter sp., Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa were subjected for the screening for extended spectrum β-lactamase, carbapenemase, as well as plasmid-mediated AmpC β-lactamase genes. BOX-PCR genotyping was used for the genotyping of these isolates. Our results show that all four pathogens are involved in the intra- and/or interhospital dissemination between the Lithuanian healthcare institutions. The level of transmissions differed between pathogens, and the worst situation was detected for Acinetobacter sp. followed by E. coli. In almost all cases, transmissible strains had at least one gene conferring β-lactam resistance, thereby contributing to the dissemination of the resistance determinants in and between Lithuanian hospitals. Our study clearly demonstrated that immediate actions, more effective strategy, and surveillance are needed to confine and prevent further spread of multidrug resistant Gram-negative pathogenic bacteria in Lithuanian healthcare institutions. | 2019 | 30339100 |
| 2492 | 12 | 0.8559 | Mobile Tigecycline Resistance: An Emerging Health Catastrophe Requiring Urgent One Health Global Intervention. Mobile tigecycline resistance (MTR) threatens the clinical efficacy of the salvage antibiotic, tigecycline (TIG) used in treating deadly infections in humans caused by superbugs (multidrug-, extensively drug-, and pandrug-resistant bacteria), including carbapenem- and colistin-resistant bacteria. Currently, non-mobile tet(X) and mobile plasmid-mediated transmissible tet(X) and resistance-nodulation-division (RND) efflux pump tmexCD-toprJ genes, conferring high-level TIG (HLT) resistance have been detected in humans, animals, and environmental ecosystems. Given the increasing rate of development and spread of plasmid-mediated resistance against the two last-resort antibiotics, colistin (COL) and TIG, there is a need to alert the global community on the emergence and spread of plasmid-mediated HLT resistance and the need for nations, especially developing countries, to increase their antimicrobial stewardship. Justifiably, MTR spread projects One Health ramifications and portends a monumental threat to global public and animal health, which could lead to outrageous health and economic impact due to limited options for therapy. To delve more into this very important subject matter, this current work will discuss why MTR is an emerging health catastrophe requiring urgent One Health global intervention, which has been constructed as follows: (a) antimicrobial activity of TIG; (b) mechanism of TIG resistance; (c) distribution, reservoirs, and traits of MTR gene-harboring isolates; (d) causes of MTR development; (e) possible MTR gene transfer mode and One Health implication; and (f) MTR spread and mitigating strategies. | 2022 | 35979498 |
| 1556 | 13 | 0.8557 | Resistance to Colistin in Klebsiella Pneumoniae: A 4.0 Strain? The global rise of multidrug-resistant gram-negative bacteria represents an increasing threat to patient safety. From the first observation of a carbapenem-resistant gram-negative bacteria a global spread of extended-spectrum beta-lactamases and carbapenemases producing Klebsiella pneumoniae has been observed. Treatment options for multidrug-resistant K. pneumoniae are actually limited to combination therapy with some aminoglycosides, tigecycline and to older antimicrobial agents. Unfortunately, the prevalence of colistin-resistant and tigecycline-resistant K. pneumoniae is increasing globally. Infection due to colistin-resistant K. pneumoniae represents an independent risk factor for mortality. Resistance to colistin in K. pneumoniae may be multifactorial, as it is mediated by chromosomal genes or plasmids. The emergence of transmissible, plasmid-mediated colistin resistance is an alarming finding. The absence of new agents effective against resistant Gram-negative pathogens means that enhanced surveillance, compliance with infection prevention procedures, and antimicrobial stewardship programs will be required to limit the spread of colistin-resistant K. pneumoniae. | 2017 | 28626539 |
| 2494 | 14 | 0.8556 | Dissemination of virulence and resistance genes among Klebsiella pneumoniae via outer membrane vesicle: An important plasmid transfer mechanism to promote the emergence of carbapenem-resistant hypervirulent Klebsiella pneumoniae. Klebsiella pneumoniae is well-known opportunistic enterobacteria involved in complex clinical infections in humans and animals. The domestic animals might be a source of the multidrug-resistant virulent K. pneumoniae to humans. K. pneumoniae infections in domestic animals are considered as an emergent global concern. The horizontal gene transfer plays essential roles in bacterial genome evolution by spread of virulence and resistance determinants. However, the virulence genes can be transferred horizontally via K. pneumoniae-derived outer membrane vesicles (OMVs) remains to be unreported. In this study, we performed complete genome sequencing of two K. pneumoniae HvK2115 and CRK3022 with hypervirulent or carbapenem-resistant traits. OMVs from K. pneumoniae HvK2115 and CRK3022 were purified and observed. The carriage of virulence or resistance genes in K. pneumoniae OMVs was identified. The influence of OMVs on the horizontal transfer of virulence-related or drug-resistant plasmids among K. pneumoniae strains was evaluated thoroughly. The plasmid transfer to recipient bacteria through OMVs was identified by polymerase chain reaction, pulsed field gel electrophoresis and Southern blot. This study revealed that OMVs could mediate the intraspecific and interspecific horizontal transfer of the virulence plasmid phvK2115. OMVs could simultaneously transfer two resistance plasmids into K. pneumoniae and Escherichia coli recipient strains. OMVs-mediated horizontal transfer of virulence plasmid phvK2115 could significantly enhance the pathogenicity of human carbapenem-resistant K. pneumoniae CRK3022. The CRK3022 acquired the virulence plasmid phvK2115 could become a CR-hvKp strain. It was critically important that OMVs-mediated horizontal transfer of phvK2115 lead to the coexistence of virulence and carbapenem-resistance genes in K. pneumoniae, resulting in the emerging of carbapenem-resistant hypervirulent K. pneumoniae. | 2022 | 35679514 |
| 6615 | 15 | 0.8556 | Is Africa ready for mobile colistin resistance threat? Antimicrobial resistance is a growing public health problem and a threat to effective treatment and prevention of an array of infections caused by bacteria. Africa is already faced with many socio-economic and health crises. Many countries in Africa can seldom boast of a standardized health care facility comparable to those in developed countries. Yet, the non-therapeutic use of COL has been banned in developed countries. However, in Africa, except for South Africa, COL is an over-the-counter (OTC) medication sold and dispensed by non-professionals/without a veterinarian's supervision. The ban of non-therapeutic COL in developed countries has proven to reduce the development of mobile colistin resistance (MCR) in humans and animals. The unregulated use of COL has been proven to select pathogenic and commensal bacteria resistance. A transmissible plasmid-mediated colistin determinant, mobile COL resistance (mcr) gene, which is rapidly transferred/acquired horizontally or laterally intra/inter-species/genera, has been reported. A highly promiscuous mobile genetic element like plasmids containing transposons, insertion sequences, and integrons aid the carriage/rapid transfer and acquisition of these mcr genes. Hence, we highlight the danger posed by escalating colistin (COL) resistance in the continent and the impetus to halt the indiscriminate and non-therapeutic use of COL to protect public health. | 2021 | 34377360 |
| 1557 | 16 | 0.8555 | Carbapenemase-producing Klebsiella pneumoniae. The continuing emergence of infections due to multidrug resistant bacteria is a serious public health problem. Klebsiella pneumoniae, which commonly acquires resistance encoded on mobile genetic elements, including ones that encode carbapenemases, is a prime example. K. pneumoniae carrying such genetic material, including both blaKPC and genes encoding metallo-β-lactamases, have spread globally. Many carbapenemase-producing K. pneumoniae are resistant to multiple antibiotic classes beyond β-lactams, including tetracyclines, aminoglycosides, and fluoroquinolones. The optimal treatment, if any, for infections due to these organisms is unclear but, paradoxically, appears to often require the inclusion of an optimally administered carbapenem. | 2014 | 25343037 |

| 841 | 18 | 0.8554 | blaOXA-48 carrying clonal colistin resistant-carbapenem resistant Klebsiella pneumoniae in neonate intensive care unit, India. Bacteria resistant to colistin, a last resort antibiotic reflect the pre-antibiotic era. In this study, colistin resistance carbapenem-resistant K. pneumoniae (COL(R)- CRKP) strains from neonate's intensive care unit were evaluated. Molecular analysis showed that all the four colistin resistant K. pneumoniae isolates were clonally related with strong biofilm formation ability and harbored bla(SHV-34) and bla(OXA-48) genes. Our result suggested the need of proper surveillance and adequate infection control to limiting the spread of these organisms. | 2016 | 27622347 |
| 2517 | 19 | 0.8554 | The Epidemiology of Carbapenem-Resistant Enterobacteriaceae: The Impact and Evolution of a Global Menace. Carbapenem-resistant Enterobacteriaceae (CRE) are a serious public health threat. Infections due to these organisms are associated with significant morbidity and mortality. Mechanisms of drug resistance in gram-negative bacteria (GNB) are numerous; β-lactamase genes carried on mobile genetic elements are a key mechanism for the rapid spread of antibiotic-resistant GNB worldwide. Transmissible carbapenem-resistance in Enterobacteriaceae has been recognized for the last 2 decades, but global dissemination of carbapenemase-producing Enterobacteriaceae (CPE) is a more recent problem that, once initiated, has been occurring at an alarming pace. In this article, we discuss the evolution of CRE, with a focus on the epidemiology of the CPE pandemic; review risk factors for colonization and infection with the most common transmissible CPE worldwide, Klebsiella pneumoniae carbapenemase-producing K. pneumoniae; and present strategies used to halt the striking spread of these deadly pathogens. | 2017 | 28375512 |
