Abstract
Klebsiella pneumoniae is considered an opportunistic pathogen, constituting an ongoing health concern for immunocompromised patients, the elderly, and neonates. Reports on the isolation of K. pneumoniae from other sources are increasing, many of which express multidrug-resistant (MDR) phenotypes. Three phylogroups were identified based on nucleotide differences. Niche environments, including plants, animals, and humans appear to be colonized by different phylogroups, among which KpI (K. pneumoniae) is commonly associated with human infection. Infections with K. pneumoniae can be transmitted through contaminated food or water and can be associated with community-acquired infections or between persons and animals involved in hospital-acquired infections. Increasing reports are describing detections along the food chain, suggesting the possibility exists that this could be a hitherto unexplored reservoir for this opportunistic bacterial pathogen. Expression of MDR phenotypes elaborated by these bacteria is due to the nature of various plasmids carrying antimicrobial resistance (AMR)-encoding genes, and is a challenge to animal, environmental, and human health alike. Raman spectroscopy has the potential to provide for the rapid identification and screening of antimicrobial susceptibility of Klebsiella isolates. Moreover, hypervirulent isolates linked with extraintestinal infections express phenotypes that may support their niche adaptation. In this review, the prevalence, reservoirs, AMR, Raman spectroscopy detection, and pathogenicity of K. pneumoniae are summarized and various extraintestinal infection pathways are further narrated to extend our understanding of its adaptation and survival ability in reservoirs, and associated disease risks.

Abstract
This study aimed to describe the epidemiology and antimicrobial resistance trends of Klebsiella pneumoniae bloodstream infection (BSI) in Ireland, in conjunction with national antimicrobial consumption data, during the period 2008 to 2013. A retrospective cohort study of K. pneumoniae BSI cases was conducted, based on notifications from Irish microbiology laboratories to the Health Protection Surveillance Centre (HPSC). In total, 1942 K. pneumoniae BSI cases were identified over 6 years, with 310 reported in 2008 and 326 reported in 2013. From 2008 to 2013, the proportion of isolates resistant to co-amoxiclav (24 % versus 29 %), piperacillin-tazobactam (11 % versus 27 %), third generation cephalosporins (3GC) (11 % versus 21 %), fluoroquinolones (13 % versus 21 %) and gentamicin (11 % versus 17 %) increased overall, concurrent with increasing national rates of antimicrobial consumption in Ireland (acute hospitals: 35.87 versus 39.77 defined daily doses (DDD) per 100 bed days used (BDU); and community: 6.38 versus 7.85 DDD per 1000 inhabitants per day (DID)). Enhanced data on the patient's admission route was available for 735 (38 %) cases. Overall, 51 % (n = 378) were categorised as 'acquired in the reporting hospital'. The all-cause mortality was 20 %, with 115 deaths, 101 (88 %) of whom died within 30 days of blood culture sampling date. K. pneumoniae is the second most common cause of Gram-negative BSI in Ireland, with most cases healthcare-associated and an all-cause mortality of 20 % reported in this study. Annual increases in resistance to different antimicrobial classes and in a multi-drug resistant phenotype have been observed, concurrent with increasing national broad spectrum antimicrobial consumption. These trends portend a risk to patient outcomes and highlight the urgency for individual prescribers to evaluate their antimicrobial prescribing habits in hospitals, long-term care and community settings.

Abstract
In 2012, the European Centre for Disease Prevention and Control (ECDC) launched the ‘European survey of carbapenemase-producing Enterobacteriaceae (EuSCAPE)’ project to gain insights into the occurrence and epidemiology of carbapenemase-producing Enterobacteriaceae (CPE), to increase the awareness of the spread of CPE, and to build and enhance the laboratory capacity for diagnosis and surveillance of CPE in Europe. Data collected through a post-EuSCAPE feedback questionnaire in May 2015 documented improvement compared with 2013 in capacity and ability to detect CPE and identify the different carbapenemases genes in the 38 participating countries, thus contributing to their awareness of and knowledge about the spread of CPE. Over the last two years, the epidemiological situation of CPE worsened, in particular with the rapid spread of carbapenem-hydrolysing oxacillinase-48 (OXA-48)- and New Delhi metallo-beta-lactamase (NDM)-producing Enterobacteriaceae. In 2015, 13/38 countries reported inter-regional spread of or an endemic situation for CPE, compared with 6/38 in 2013. Only three countries replied that they had not identified one single case of CPE. The ongoing spread of CPE represents an increasing threat to patient safety in European hospitals, and a majority of countries reacted by establishing national CPE surveillances systems and issuing guidance on control measures for health professionals. However, 14 countries still lacked specific national guidelines for prevention and control of CPE in mid-2015.

Abstract
BACKGROUND Carbapenemase-producing Enterobacteriaceae (CPE) strains are encountered with increasing frequency in Europe. In November 2010 the European Centre for Disease Control (ECDC) graded Ireland as only having sporadic occurrence of CPE. AIM To describe the epidemiological and molecular typing analysis of the first outbreak of OXA-48-producing Klebsiella pneumoniae in an Irish tertiary care referral centre. METHODS Sixteen OXA-48-producing K. pneumoniae isolates were detected, from both clinical and screening specimens, and analysed by pulsed-field gel electrophoresis and by multi-locus sequence typing. FINDINGS Typing analysis revealed that two outbreak strains were circulating in the hospital, one among surgical patients and one among medical patients. The 'medical strain' ST13 had already been identified as an internationally disseminated clone, whereas the 'surgical strain' ST221 had not previously been reported as an OXA-48-carrying strain. CONCLUSION Although the outbreak on surgical wards was successfully controlled by implementing strict infection control measures, intermittent detection of individual patients carrying the 'medical strain' of OXA-48 K. pneumoniae has persisted since then. The experience from this outbreak suggests that OXA-48 K. pneumoniae is endemic at low level in the healthcare setting in the Dublin region.

Abstract
SUMMARY The spread of Enterobacteriaceae, primarily Klebsiella pneumoniae, producing KPC, VIM, IMP, and NDM carbapenemases, is causing an unprecedented public health crisis. Carbapenemase-producing enterobacteria (CPE) infect mainly hospitalized patients but also have been spreading in long-term care facilities. Given their multidrug resistance, therapeutic options are limited and, as discussed here, should be reevaluated and optimized. Based on susceptibility data, colistin and tigecycline are commonly used to treat CPE infections. Nevertheless, a review of the literature revealed high failure rates in cases of monotherapy with these drugs, whilst monotherapy with either a carbapenem or an aminoglycoside appeared to be more effective. Combination therapies not including carbapenems were comparable to aminoglycoside and carbapenem monotherapies. Higher success rates have been achieved with carbapenem-containing combinations. Pharmacodynamic simulations and experimental infections indicate that modification of the current patterns of carbapenem use against CPE warrants further attention. Epidemiological data, though fragmentary in many countries, indicate CPE foci and transmission routes, to some extent, whilst also underlining the lack of international collaborative systems that could react promptly and effectively. Fortunately, there are sound studies showing successful containment of CPE by bundles of measures, among which the most important are active surveillance cultures, separation of carriers, and assignment of dedicated nursing staff.

Abstract
The epidemiology of carbapenemase-producing Enterobacteriaceae (CPE) in Ireland is changing, with an increase in the number of reported cases in late 2010 and early 2011. Reported cases were predominantly linked to critical care units. In June 2011, a four-week national pilot survey took place in 40 Irish critical care units (37 adult and three paediatric) to examine the prevalence of rectal carriage of CPE and inform national CPE screening guidelines. A total of 760 screening swabs were taken over the study period, and CPE were not detected in any of the participating critical care units.

Abstract
Plasmid-acquired carbapenemases in Enterobacteriaceae, which were first discovered in Europe in the 1990s, are now increasingly being identified at an alarming rate. Although their hydrolysis spectrum may vary, they hydrolyse most β-lactams, including carbapenems. They are mostly of the KPC, VIM, NDM and OXA-48 types. Their prevalence in Europe as reported in 2011 varies significantly from high (Greece and Italy) to low (Nordic countries). The types of carbapenemase vary among countries, partially depending on the cultural/population exchange relationship between the European countries and the possible reservoirs of each carbapenemase. Carbapenemase producers are mainly identified among Klebsiella pneumoniae and Escherichia coli, and still mostly in hospital settings and rarely in the community. Although important nosocomial outbreaks with carbapenemase-producing Enterobacteriaceae have been extensively reported, many new cases are still related to importation from a foreign country. Rapid identification of colonized or infected patients and screening of carriers is possible, and will probably be effective for prevention of a scenario of endemicity, as now reported for extended-spectrum β-lactamase (mainly CTX-M) producers in all European countries.
