Dendrogram for comparison of identification by MALDI-TOF MS with 16S rRNA sequencing. Identification of Gram-positive, catalase-negative cocci (PNC) isolated from milk samples of cows with intramammary infection by sequencing the 16S rRNA gene (reference method) and by mass spectroscopy (MS) using the matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) technology. An illustrative subset of 41 strains is depicted in the dendrogram. The degree of similarity is illustrated in percentage by the scale. Identification included Streptococcus uberis (Strep. uberis), Streptococcus dysgalactiae subsp. dysgalactiae (Strep. dysgalactiae), Streptococcus agalactiae (Strep. agalactiae) and other streptococcal species, Aerococcus viridans (A. viridans), Enterococcus faecalis (E. faecalis), Enterococcus saccharolyticus (E. saccharolyticus), Lactococcus garvieae (L. garvieae), and Lactococcus lactis (L. lactis). Strep. mitis/oralis/pseudopneumoniae: the indicated taxon may be a member of Strep. mitis, of Strep oralis, or of Strep. pseudopneumoniae.
