Evolutionary Dynamics of Vibrio cholerae O1 following a Single-Source Introduction to Haiti
Intensive mutational processes can account for virtually all of the observed genetic polymorphism, with no demonstrable contribution from horizontal gene transfer (HGT), and no evidence that environmental strains have played a role in the evolution of the outbreak strain. Expand
Novel Epidemic Clones of Listeria monocytogenes, United States, 2011
We identified a novel serotype 1/2a outbreak strain and 2 novel epidemic clones of Listeria monocytogenes while investigating a foodborne outbreak of listeriosis associated with consumption ofExpand
Molecular and Phenotypic Characterization of Vibrio navarrensis Isolates Associated with Human Illness
Four of the 18 strains characterized may represent a new Vibrio species, distinct from V. navarrensis, and found that they clustered with two previously characterized VIBrio navar Rensis isolates in a phylogenetic analysis. Expand
Genome Sequences of Vibrio navarrensis, a Potential Human Pathogen
Preliminary analyses of the first genome sequences of three V. navarrensis strains obtained from clinical and environmental sources reveal that the bacterium contains genes commonly associated with virulence in other human pathogens. Expand
Multiplex polymerase chain reaction for identification of Escherichia coli, Escherichia albertii and Escherichia fergusonii.
The assay was 100% sensitive and specific for detecting the expected species and offers a quick and accurate strategy for identifying E. coli, E. albertii, and E. fergusonii in either a single reaction or by in silico PCR with sequence assemblies. Expand
Determination of Evolutionary Relationships of Outbreak-Associated Listeria monocytogenes Strains of Serotypes 1/2a and 1/2b by Whole-Genome Sequencing
ABSTRACT We used whole-genome sequencing to determine evolutionary relationships among 20 outbreak-associated clinical isolates of Listeria monocytogenes serotypes 1/2a and 1/2b. Isolates from 6 ofExpand
Yersinia enterocolitica infections associated with improperly pasteurized milk products: southwest Pennsylvania, March–August, 2011
This study investigated the outbreak's source and scope in order to prevent further transmission of Yersinia enterocolitica infections in southwestern Pennsylvania, USA, and found that consumption of pasteurized milk is common and outbreaks have the potential to become large. Expand
Vibrio furnissii: an Unusual Cause of Bacteremia and Skin Lesions after Ingestion of Seafood
A patient who developed skin lesions and V. furnissii bacteremia and was successfully treated with fluoroquinolones is described, suggesting this organism may be a serious pathogen in patients with underlying comorbidities who are exposed to seafood. Expand

Four Vibrio spp. isolates from the historical culture collection at the Centers for Disease Control and Prevention, obtained from human blood specimens (n=3) and river water (n=1), showExpand
Shiga Toxin-Producing E. coli Infections Associated with Romaine Lettuce - United States, 2018.
The investigation highlights the complexities associated with investigating outbreaks involving widespread environmental contamination and reports on the largest multistate leafy green-linked STEC O157 outbreak in several decades. Expand
