Abstract We characterized 57 isolates from a 2-phase clonal outbreak of New Delhi metallo-β-lactamase–producing Eschericha coli, involving 9 Israeli hospitals; all but 1 isolate belonged to sequence-type (ST) 410. Most isolates in the second phase harbored blaKPC-2 in addition to blaNDM-5. Genetic sequencing revealed most dual-carbapenemase–producing isolates to be monophyletically derived from a common ancestor.

Here, we report the draft genome sequence of a sequence type 111 Pseudomonas aeruginosa strain isolated in 2014 from a patient at the NIH Clinical Center. This P. aeruginosa strain exhibits pan-drug resistance and harbors the bla KPC-2 gene, encoding the Klebsiella pneumoniae carbapenemase enzyme, on a plasmid.

Abstract Background Carbapenemase-producing Klebsiella pneumoniae has become a global priority, not least in low- and middle-income countries. Here, we report the emergence and clinical impact of a novel Klebsiella pneumoniae carbapenemase–producing K. pneumoniae (KPC-KP) sequence type (ST) 16 clone in a clonal complex (CC) 258–endemic setting. Methods In a teaching Brazilian hospital, a retrospective cohort of adult KPC-KP bloodstream infection (BSI) cases (January 2014 to December 2016) was established to study the molecular epidemiology and its impact on outcome (30-day all-cause mortality). KPC-KP isolates underwent multilocus sequence typing. Survival analysis between ST/CC groups and risk factors for fatal outcome (logistic regression) were evaluated. Representative isolates underwent whole-genome sequencing and had their virulence tested in a Galleria larvae model. Results One hundred sixty-five unique KPC-KP BSI cases were identified. CC258 was predominant (66%), followed by ST16 (12%). The overall 30-day mortality rate was 60%; in contrast, 95% of ST16 cases were fatal. Patients’ severity scores were high and baseline clinical variables were not statistically different across STs. In multivariate analysis, ST16 (odds ratio [OR], 21.4; 95% confidence interval [CI], 2.3–202.8; P = .008) and septic shock (OR, 11.9; 95% CI, 4.2–34.1; P < .001) were independent risk factors for fatal outcome. The ST16 clone carried up to 14 resistance genes, including blaKPC-2 in an IncFIBpQIL plasmid, KL51 capsule, and yersiniabactin virulence determinants. The ST16 clone was highly pathogenic in the larvae model. Conclusions Mortality rates were high in this KPC-KP BSI cohort, where CC258 is endemic. An emerging ST16 clone was associated with high mortality. Our results suggest that even in endemic settings, highly virulent clones can rapidly emerge demanding constant monitoring.

Abstract Klebsiella pneumoniae carbapenemase-producing P. aeruginosa (KPC-CRPA) are rare in the United States. An outbreak of KPC-CRPA was investigated in Texas using molecular and epidemiologic methods and 17 cases of KPC-CRPA were identified. The isolates were genetically related and harbored the emerging P. aeruginosa multilocus sequence type 235, the first in the United States.

AbstractWe describe transmission of Klebsiella pneumoniae carbapenemase-producing Escherichia coli sequence type (ST) 1193 in a group home. E. coli ST1193 is an emerging multidrug-resistant clone not previously shown to carry carbapenemases in the United States. Our investigation illustrates the potential of residential group homes to amplify rare combinations of pathogens and resistance mechanisms.

We report here the draft genome sequence of Acinetobacter baumannii strain M3AC14-8, sequence type 2 (ST2), carrying a chromosomally carried bla KPC-2 gene. The draft genome consists of a total length of 4.11 Mbp and a G+C content of 39.25%.
