Polynucleobacter Heckmann and Schmidt 1987
General information
Description and emendation
Bacterial endosymbionts. Multiple nucleoids. Inhabit the cytoplasm of the following closely related Euplotes spp.: E. aediculatus, E. eurystomus, E. plumipes, E. daiduleos, E. octocarinatus, E. patella, and E. woodrufi. Essential for their host species. Nonmotile.
1: The monotypic genus belongs to the family Burkholderiaceae, and harbours endosymbiotic strains of several Euplotes species and free-living strains dwelling in the water column of freshwater lakes, ponds and streams. According to the description of Heckmann & Schmidt (1987), endosymbionts of the freshwater species E. aediculatus, E. eurystomus, E. plumipes, E. daidaleos, E. octocarinatus, E. patella and E. woodruffi, which are penicillin-sensitive and possess multiple nucleoid-like structures, belong to this genus. Furthermore, endosymbionts of Euplotes moebiusi f. quadricirratus possess the morphological characteristics described for Polynucleobacter species. However, for most of these endosymbionts the examination of their phylogenetic affiliation with the genus Polynucleobacter is lacking. Vannini et al. (2005) demonstrated by phylogenetic and ultrastructural investigations that endosymbionts of the brackish-water species E. harpa also belong to this genus. Not all strains affiliated with the genus possess multiple nucleoid-like structures as indicated by the genus name.
