ABSTRACT Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae have become more common in the United States and throughout the world. We used pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) to examine the molecular epidemiology of KPC-producing K. pneumoniae isolates sent to the Centers for Disease Control and Prevention (CDC) for reference testing from 1996 to 2008. A dominant strain, sequence type 258 (ST 258), was found and likely accounts for 70% of the CDC's K. pneumoniae PFGE database. Isolates with PFGE patterns related to ST 258 were identified in 10 of the 19 U.S. states currently reporting KPC-producing K. pneumoniae, in addition to one isolate from Israel. KPC subtyping and analysis of the surrounding genetic environment were subsequently performed on 23 representative isolates. Thirteen isolates identified as ST 258 possessed either bla KPC-2 or bla KPC-3 and some variability in the Tn4401 element upstream of the bla KPC gene. Escherichia coli DH10B was successfully transformed by electroporation with KPC-encoding plasmid DNA from 20 of the 23 isolates. Restriction analysis of plasmid DNA prepared from transformants revealed a diversity of band patterns, suggesting the presence of different plasmids harboring the bla KPC gene, even among isolates of the same ST.

ABSTRACT Retrospective molecular epidemiology was performed on samples from four sooty mangabey (SM) colonies in the United States to characterize simian immunodeficiency virus SIVsm diversity in SMs and to trace virus circulation among different primate centers (PCs) over the past 30 years. The following SIVsm sequences were collected from different monkeys: 55 SIVsm isolates from the Tulane PC sampled between 1984 and 2004, 10 SIVsm isolates from the Yerkes PC sampled in 2002, 7 SIVsm isolates from the New Iberia PC sampled between 1979 and 1986, and 8 SIVsm isolates from the California PC sampled between 1975 and 1977. PCR and sequencing were done to characterize the gag, pol, and env gp36 genes. Phylogenetic analyses were correlated with the epidemiological data. Our analysis identified nine different divergent phylogenetic lineages that cocirculated in these four SM colonies in the Unites States in the past 30 years. Lineages 1 to 5 have been identified previously. Two of the newly identified SIVsm lineages found in SMs are ancestral to SIVmac251/SIVmac239/SIVmne and SIVstm. We further identified the origin of these two macaque viruses in SMs from the California National Primate Research Center. The diversity of SIVsm isolates in PCs in the United States mirrors that of human immunodeficiency virus type 1 (HIV-1) group M subtypes and offers a model for the molecular epidemiology of HIV and a new approach to vaccine testing. The cocirculation of divergent SIVsm strains in PCs resulted in founder effects, superinfections, and recombinations. This large array of SIVsm strains showing the same magnitude of diversity as HIV-1 group M subtypes should be extremely useful for modeling the efficacy of vaccination strategies under the real-world conditions of HIV-1 diversity. The genetic variability of SIVsm strains among PCs may influence the diagnosis and monitoring of SIVsm infection and, consequently, may bias the results of pathogenesis studies.
