Description and Significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

Genome Structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?

The genome of Bordetella parapertussis typically consists of a single circular chromosome. The size of this genome is approximately 4.7 million base pairs (Mbp), with a G+C content of around 65%. Comparative genomic studies have revealed ongoing evolutionary changes, with the identification of single nucleotide polymorphisms and short insertions and deletions compared to reference genomes.

B. parapertussis has diverged into two distinct lineages: one that causes whooping cough in infants and another that infects sheep. Unlike B. pertussis, B. parapertussis is oxidase-negative, indicating differences in respiratory mechanisms.

The genome annotation of a recently sequenced B. parapertussis isolate from Iran, IRBP134, revealed approximately 4,620 potential coding sequences and 55 RNA sequences, including 63 tRNAs, as well as one large and one small subunit of ribosomal RNA. The genome assembly generated 72 scaffolds with an N50 value of 106,547. [9]
