Highlights:
- Legionella-like isolates, were isolated from a cold-water distribution system on a cruise ship in 2017.
- Colonies displayed phenotypic characteristics typical of the family Legionellaceae, including a requirement for l-cysteine and testing catalase positive.
- The bacteria were Gram-negative, rod-shaped, grew aerobically on buffered charcoal yeast extract agar and weakly grew on glycine-vancomycin-polymyxin-cycloheximide media at 36 °C with the ability to autofluoresce a blue-white colour when placed under a long-wavelength UV light (365 nm).
- The isolates were closely related to Legionella cherrii. but the results obtained in this study confirm the status of an independent species.
- The name proposed for this species is Legionella sheltonii nov. with PATHC038T(CCUG 76918T, ATCC TSD-370) as the type strain.
