I. INTRODUCTION The microbiota of an individual's gastrointestinal tract, comprising microbes, their genes, and their functional traits, is fundamental to host digestion (McWhorter, Caviedes-Vidal & Karasov, 2009), detoxification (Kohl et al., 2016), development (Parfrey, Moreau & Russell, 2018), immune function (Broom & Kogut, 2018), protection from pathogenic bacteria (Roggenbuck et al., 2014; Mendoza et al., 2017), and cognitive performance (Davidson, Raulo & Knowles, 2020a).

Abstract Acinetobacter baumannii, an important pathogen known for its widespread antibiotic resistance, has been the focus of extensive research within its genus, primarily involving clinical isolates. Consequently, data on environmental A. baumannii and other Acinetobacter species remain limited. Here, we utilised Illumina and Nanopore sequencing to analyse the genomes of ten Acinetobacter isolates representing six different species sourced from aquatic environments in South Australia.

Abstract Antimicrobial resistance (AMR) — the ability of microorganisms to adapt and survive under diverse chemical selection pressures — is influenced by complex interactions between humans, companion and food-producing animals, wildlife, insects and the environment. To understand and manage the threat posed to health (human, animal, plant and environmental) and security (food and water security and biosecurity), a multifaceted ‘One Health’ approach to AMR surveillance is required.
