| a house for two--double bacterial infection in euplotes woodruffi sq1 (ciliophora, euplotia) sampled in southeastern brazil. | several ciliated protists form symbiotic associations with a diversity of microorganisms, leading to drastic impact on their ecology and evolution. in this work, two euplotes spp. sampled in rio de janeiro, brazil, were identified based on morphological and molecular features as euplotes woodruffi strain sq1 and e. encysticus strain sq2 and investigated for the presence of endosymbionts. while e. woodruffi sq1 stably hosts two bacterial populations, namely polynucleobacter necessarius (betaprote ... | 2016 | 26381539 |
