Insights

Campylobacter jejuni subspecies jejuni causes human gastroenteritis. Researchers sequenced the genome of C. jejuni strain P4549 from a rhesus monkey, revealing its chromosome and plasmid structures.

Area of Science:

  • Microbiology
  • Genomics
  • Veterinary Science

Background:

  • Campylobacter jejuni subspecies jejuni is a primary bacterial pathogen responsible for human gastroenteritis worldwide.
  • Understanding the genomic makeup of C. jejuni strains is crucial for tracking its transmission and developing control strategies.

Purpose of the Study:

  • To report the complete genome sequence of Campylobacter jejuni strain P4549.
  • To characterize the genomic structure, including chromosomal and plasmid DNA, of this strain isolated from a non-human primate.

Main Methods:

  • Whole-genome sequencing of Campylobacter jejuni strain P4549.
  • Bioinformatic analysis to assemble and annotate the circular chromosome and plasmids.

Main Results:

  • The genome consists of a single circular chromosome of 1,729,940 base pairs.
  • Two circular plasmids were identified with sizes of 50,482 bp and 7,259 bp, respectively.

Conclusions:

  • The genome sequencing provides a foundational resource for studying Campylobacter jejuni P4549.
  • This genomic data can aid in understanding the evolution and host-pathogen interactions of C. jejuni, particularly in zoonotic contexts.
