Complete Genome Sequence of Escherichia coli Strain M8, Isolated from ob/ob Mice

Area of Science:

• Microbiology
• Genomics

Background:

• Escherichia coli is a common gut bacterium.
• Ob/ob mice are a model for studying obesity and metabolic disorders.

Purpose of the Study:

• To characterize the genome of an E. coli strain isolated from an ob/ob mouse.
• To identify genetic elements such as chromosomes and plasmids within the isolated strain.

Main Methods:

• Isolation of Escherichia coli from an ob/ob mouse.
• Whole-genome sequencing of the bacterial strain.
• Analysis of chromosomal and plasmid DNA sequences.

Main Results:

• Successfully sequenced the whole genome of the E. coli strain.
• Determined the size of the chromosome to be approximately 5.1 Mb.
• Identified three plasmids with sizes of approximately 160 kb, 6 kb, and 4 kb.

Conclusions:

• The study provides a comprehensive genomic description of an E. coli strain from a specific mouse model.
• The identified plasmids may play a role in the bacterium's adaptation or function within the host.
• This genomic data can serve as a reference for future studies on E. coli in metabolic disease models.
