Nicoletella is a monotypic genus in the family Pasteurellaceae as determined by a polyphasic approach using 19 strains. They are Gram‐negative, nonmotile pleomorphic rods. Isolates do not grow on MacConkey agar and do not require hemin or β‐NAD. They reduce nitrate to nitrite and are catalase‐, oxidase‐, and urease‐positive. DNA–DNA hybridization data and multilocus phylogenetic analysis, including 16S rRNA gene, rpoB, and infB sequencing, clearly placed Nicoletella as a discrete genus in the family Pasteurellaceae. Otherwise, the only currently known species of the genus N. semolina is biochemically inert. Growth is fastidious, and the isolates have a distinctive colony morphology, with the colonies being dry and waxy and looking like a semolina particle that can be moved around on an agar plate without losing their shape.

DNA G + C content (mol%): 39.4 (genome sequence).

Type species: Nicoletella semolina Kuhnert et al. 2004, VL102.
