Recent genomic characterisation of translocating HMLN-1 isolated from mesenteric lymph nodes (MLNs) and blood of a patient with a fatal case of pancreatitis revealed the presence of a type 6 secretion system (T6SS) that was not present in non-translocating strains. This strain was also genomically similar to adherent-invasive (AIEC) LF82 pathotype. We aimed to identify the role of T6SS-1 in the pathogenesis of this strain and other pathogenic .

Whilst the pathogenic mechanisms underlying IBD remain poorly characterised, adherent-invasive (AIEC) has been implicated as a microbiological factor in disease pathogenesis. These strains show an enhanced ability to diffusely adhere to and invade intestinal epithelial cells, along with the ability to survive and replicate within macrophages.

Article Synopsis
- Isolated strains USC-21046 and USC-21048 were found in foaming coastal waters of Queensland, Australia, and showed typical characteristics of their genus, including specific polar lipids and fatty acids.
- Phylogenomic analysis indicated that strain USC-21046 has 80.4% genome similarity with two reference strains, while USC-21048 has 83.6%, and both were distinguished by differences in physiological and chemotaxonomic traits.
- The strains have genome lengths of approximately 6.9 million bp, with G+C contents of 65.2% and 67.8%, and are proposed as new species, with the names sp. nov. for USC-21046
Introduction: The virulence-associated gene (VAG) repertoire and clonal organization of uropathogenic (UPEC) strains is influenced by host demographic, geographic locale, and the setting of urinary tract infection (UTI). Nevertheless, a direct comparison of these features among Australian and Turkish UPEC remains unexplored. Accordingly, this study investigated the clonal composition and virulence characteristics of a collection of UPEC isolated from Australian and Turkish UTI patients.
