Draft genome sequence of Enterobacter chengduensis ECC445, isolated from fresh water in the West Indies

OBJECTIVES

The Enterobacter cloacae complex is considered an important opportunistic pathogen. It comprises many members that remain difficult to delineate by phenotypic approaches. Despite its importance in human infection, there is a lack of information on associated members in other compartments. Here we report the first de novo assembled and annotated whole-genome sequence of a E. chengduensis strain isolated from the environment.

DATA DESCRIPTION

ECC445 specimen was isolated in 2018 from a drinking water catchment point in Guadeloupe. It was clearly related to E. chengduensis species according to hsp60 typing and genomic comparison. Its whole-genome sequence is 5,211,280-bp long divided into 68 contigs, and presents a G + C content of 55.78%. This genome and associated datasets provided here will serve as a useful resource for further analyses of this rarely reported Enterobacter species.

An Update on Novel Taxa and Revised Taxonomic Status of Bacteria Isolated from Domestic Animals Described in 2018 to 2021

Novel bacterial taxonomy and nomenclature revisions can have significant impacts on clinical practice, disease epidemiology, and veterinary microbiology laboratory operations. Expansion of research on the microbiota of humans, animals, and insects has significant potential impacts on the taxonomy of organisms of clinical interest. Implications of taxonomic changes may be especially important when considering zoonotic diseases. Here, we address novel taxonomy and nomenclature revisions of veterinary significance. Noteworthy discussion centers around descriptions of novel mastitis pathogens in Streptococcaceae, Staphylococcaceae, and Actinomycetaceae; bovine reproductive tract pathogens in Corynebacteriaceae; novel members of Mannheimia spp., Leptospira spp., and Mycobacterium spp.; the transfer of Ochrobactrum spp. to Brucella spp.; and revisions to the genus Mycoplasma.

Summary of Novel Bacterial Isolates Derived from Human Clinical Specimens and Nomenclature Revisions Published in 2018 and 2019

Knowledge of novel prokaryotic taxon discovery and nomenclature revisions is of importance to clinical microbiology laboratory practice, infectious disease epidemiology, and studies of microbial pathogenesis. Relative to bacterial isolates derived from human clinical specimens, we present an in-depth summary of novel taxonomic designations and revisions to prokaryotic taxonomy that were published in 2018 and 2019. Included are several changes pertinent to former designations of or within Propionibacterium spp., Corynebacterium spp., Clostridium spp., Mycoplasma spp., Methylobacterium spp., and Enterobacteriaceae Future efforts to ascertain clinical relevance for many of these changes may be augmented by a document development committee that has been appointed by the Clinical and Laboratory Standards Institute.

Complete Genome Sequence of Duncaniella muris Strain B8, Isolated from the Feces of C57/BL6 Mice

Here, the complete genome sequence of Duncaniella muris strain B8 is presented. The anaerobic strain was isolated from the feces of C57/BL6 mice and is closely related to D. muris strain DSM 103720, which is the type strain of the recently proposed genus Duncaniella of the Muribaculaceae.
