Distribution, Diversity, and Seasonality of Waterborne Salmonellae in a Rural Watershed
TLDR
The results of this study suggest that Salmonella abundance and diversity in the environment vary temporally and are strongly influenced by seasonal precipitation and water temperature. Expand

TLDR
Based on the comparative genomics, it is concluded that V. cholerae undergoes extensive genetic recombination via lateral gene transfer, and, therefore, genome assortment, not serogroup, should be used to define pathogenic V.cholerae clones. Expand
Genomic diversity of 2010 Haitian cholera outbreak strains
TLDR
The isolation of both V. cholerae O1 and non-O1/O139 early in the Haiti cholera epidemic from samples collected from victims in 18 towns across eight Arrondissements of Haiti showed two distinct populations of V.cholerae coexisted, and its role in this epidemic, either alone or in concert with V.Cholera O1, cannot be dismissed. Expand
Genome Sequence of Hybrid Vibrio cholerae O1 MJ-1236, B-33, and CIRS101 and Comparative Genomics with V. cholerae
TLDR
The absence of strain- and group-specific genomic islands, some of which appear to be prophages and phage-like elements, seems to be the most likely factor in the recent establishment of dominance of V. cholerae CIRS101 over the other two hybrid strains. Expand
Genomic and Evolutionary Analysis of Two Salmonella enterica Serovar Kentucky Sequence Types Isolated from Bovine and Poultry Sources in North America
Salmonella enterica subsp. enterica serovar Kentucky is frequently isolated from healthy poultry and dairy cows and is occasionally isolated from people with clinical disease. A genomic analysis ofExpand
Environmental factors influencing epidemic cholera.
TLDR
Using data from the 1800s, uniqueness in seasonality and mechanism of occurrence of cholera in the epidemic regions of Asia and Latin America is described. Expand
Comparative genomics of clinical and environmental Vibrio mimicus
TLDR
The results of phylogenetic analysis support the hypothesis that, in the course of evolution, V. mimicus and V. cholerae diverged from a common ancestor with a prototypic sixth pandemic genomic backbone. Expand
Occurrence of the Vibrio cholerae seventh pandemic VSP-I island and a new variant.
TLDR
Results of polymerase chain reaction screening for both known VSP-I variants indicate that the novel variant is present only in non-O1/non-O139 strains of V. cholerae and Vibrio mimicus. Expand
Diversity of Listeria monocytogenes within a U.S. dairy herd, 2004-2010.
TLDR
It is demonstrated that dairy cows can be reservoirs of a diverse population of potentially human pathogenic L. monocytogenes that represents a risk to consumers of milk, dairy products, and meat. Expand
Deep-sea hydrothermal vent bacteria related to human pathogenic Vibrio species
TLDR
Genomic, functional, and phylogenetic analyses indicate an intriguing blend of genomic features related to adaptation and animal symbiotic association, and also revealed the presence of virulence genes commonly found in Vibrio species pathogenic for humans. Expand
