## TL;DR

This paper presents the full genome sequences of two bacteria found in a marine nematode, helping to study their interactions.

## Contribution

The novelty lies in reporting genome sequences of Pseudoalteromonas strains from a marine nematode, a less-studied symbiotic relationship.

## Key findings

- Two Pseudoalteromonas undina strains were isolated from a marine nematode.
- The complete genome sequences of these strains are reported for future interaction studies.

## Abstract

Pseudoalteromonas is known to form symbiotic relationships with various marine invertebrates, but association with nematodes has not been well-explored. Here, we report the genome sequences of two Pseudoalteromonas strains isolated from a predatory marine nematode (Oncholaimidae) collected from Tybee Island, GA, that will facilitate the study of nematode-bacterial interactions.
