ABSTRACTWe report that multiple symbionts coexist inDermacentor silvarum. Based on 16S rRNA gene sequence analyses, we prove thatCoxiella-like andArsenophonus-like symbionts, with 95.6% and 96.7% sequence similarity to symbionts in the closest taxon, respectively, are novel. Moreover, we also provide evidence that theCoxiella-like symbiont appears to be the primary symbiont.

The 16S Rrna Gene

The hsp60 gene sequences were determined for 121 strains of Gram-negative anaerobic rods, including the genera Bacteroides, Barnesiella, Butyricimonas, Odoribacter, Parabacteroides, Paraprevotella, Porphyromonas, Prevotella and Tannerella. The mean pairwise hsp60 gene sequence similarity (73.8–97.1 %) between species in each genus, except for the genus Tannerella that comprises one species, was significantly less than that of the 16S rRNA gene sequence (88.3–96.3 %). Only pairwise hsp60 gene sequence similarity (97.1 %) of the genus Paraprevotella was higher than that of the 16S rRNA gene sequence (93.8 %). Each genus formed a distinct clade in the phylogenetic analysis of the hsp60 gene sequence as well as the 16S rRNA gene sequence. The phylogenetic analysis indicated a higher evolutionary rate for the hsp60 gene sequence than the 16S rRNA gene sequence, especially in the genera Porphyromonas and Prevotella. This study suggests that the hsp60 gene is a useful alternative phylogenetic marker for the identification and classification of a broad range of Gram-negative anaerobic rods.

Several pectolytic bacterial strains, mainly isolated from monocotyledonous plants and previously identified as Pectobacterium carotovorum , were thought to belong to a novel species after several taxonomic analyses including DNA–DNA hybridization. In 16S rRNA gene sequence analyses, these strains had a similarity of >97.9 % to the 16S rRNA gene sequence of strains representing six other pectobacterial species and subspecies. These strains, represented by strain SCRI 109T, also showed some unique chemotaxonomic features and quantitative differences in polar lipids, lipoquinones and fatty acids. A specific feature of strain SCRI 109T was the presence of DMK-8 lipoquinone, while the dominant fatty acids were the summed feature 3 (iso-C15 : 0 2-OH/C16 : 1ω7c), the unsaturated fatty acid C18 : 1ω7c and straight chain fatty acids, mainly C16 : 0. The DNA G+C content of strain SCRI 109T was 50.2 mol%. The taxonomic status of strain SCRI 109T and related strains in 16S rRNA gene sequence, chemotaxonomic, and physiological analyses was corroborated by the distinct clustering of these strains in multi-locus sequence analyses. It is proposed that these strains represent a novel species for which the name Pectobacterium aroidearum sp. nov. is proposed; the type strain is SCRI 109T ( = NCPPB 929T = LMG 2417T = ICMP 1522T).
