Fully Closed Genome Sequences of Five Type Strains of the Genus Cronobacter and One Cronobacter sakazakii Strain
نویسندگان
چکیده
Cronobacteris associated with infant infections and the consumption of reconstituted infant formula. Here we sequenced and closed six genomes ofC. condimenti(T),C. muytjensii(T),C. universalis(T),C. malonaticus(T),C. dublinensis(T), andC. sakazakiithat can be used as reference genomes in single nucleotide polymorphism (SNP)-based next-generation sequencing (NGS) analysis for source tracking investigations.

BACKGROUND The genus Cronobacter (formerly called Enterobacter sakazakii) is composed of five species; C. sakazakii, C. malonaticus, C. turicensis, C. muytjensii, and C. dublinensis. The genus includes opportunistic human pathogens, and the first three species have been associated with neonatal infections. The most severe diseases are caused in neonates and include fatal necrotizing enterocolit...

BACKGROUND Species of Cronobacter are widespread in the environment and are occasional food-borne pathogens associated with serious neonatal diseases, including bacteraemia, meningitis, and necrotising enterocolitis. The genus is composed of seven species: C. sakazakii, C. malonaticus, C. turicensis, C. dublinensis, C. muytjensii, C. universalis, and C. condimenti. Clinical cases are associated...
متن کاملMolecular characterization of Cronobacter lipopolysaccharide O-antigen gene clusters and development of serotype-specific PCR assays.
Cronobacter (formerly Enterobacter sakazakii) is a recently defined genus consisting of six species, C. sakazakii, C. malonaticus, C. dublinensis, C. muytjensii, C. turicensis, and Cronobacter genomospecies 1. In this study, MboII restriction fragment length polymorphism (RFLP) patterns of O-antigen gene clusters, located between galF and gnd, were used to identify serotypes in Cronobacter spp....

We introduce draft genome sequences of strains CDC1121-73 (human bronchial wash isolate) and GK1025 (powdered infant formula manufacturing facility isolate), which are both malonate-positive Cronobacter sakazakii serogroup O:2, sequence type 64. Assemblies for these strains have sizes of 4,442,307 and 4,599,266 bp and % G+C contents of 56.9 and 56.7, respectively.
متن کاملDraft Genome Sequence of a Meningitic Isolate of Cronobacter sakazakii Clonal Complex 4, Strain 8399
The Cronobacter sakazakii clonal lineage defined as clonal complex 4 (CC4), composed of nine sequence types, is associated with severe cases of neonatal meningitis. To date, only closely related C. sakazakii sequence type 4 (ST4) strains have been sequenced. C. sakazakii strain 8399, isolated from a case of neonatal meningitis, was sequenced as the first non-ST4 C. sakazakii strain.
