Background: The scoring system for bile cytology (SSBC) aims to improve bile cytology diagnostic accuracy. Here, the practicality of SSBC was verified by multiple cytotechnologists.

Methods: Bile cytological specimens were evaluated by 24 cytotechnologists using SSBC.

Three bacterial strains (Red232, Red267 and Red630) were isolated from paddy soils sampled in Japan. Cells of these strains were Gram-stain-negative, facultative anaerobic, long rod-shaped with monotrichous flagella or pilus-like structures for motility, and formed red colonies on agar plates. Phylogenetic trees based on 16S rRNA gene and multiple single-copy gene sequences showed that the three strains formed a cluster with the type strains of species, independent from any other strain genera.

Three bacterial strains, designated Red330, Red736 and Red745, were isolated from forest and paddy soils in Japan. Strains Red330, Red736 and Red745 are flagella-harbouring and strictly anaerobic bacteria forming red colonies. A 16S rRNA gene sequence-based phylogenetic tree showed that all three strains were located in a cluster, including the type strains of species, which were recently separated from the genus within the family .

Article Synopsis
  • Bacteria from a specific family are crucial for biogeochemical processes in soil and freshwater environments.
  • Three iron-reducing bacterial strains (Red96, Red100, Red88) were isolated from Japanese paddy fields and pond sediments, showing unique properties like being anaerobic, rod-shaped, and red-pigmented.
  • Phylogenetic and genomic analysis revealed that these strains form a distinct cluster, differentiating them from other species in the family, leading to the conclusion that they represent a new genus and three novel species, with proposed names for each strain.

Background: Benign and malignant cells need to be distinguished in any cytological examination of bile. Here, we report an original scoring system to improve the diagnostic accuracy of bile cytology.

Methods: The study used 158 bile aspiration samples obtained for cytological examination.
