| "candidatus cryptoprodotis polytropus," a novel rickettsia-like organism in the ciliated protist pseudomicrothorax dubius (ciliophora, nassophorea). | rickettsia-like organisms (rlo) are obligate, often highly fastidious, intracellular bacterial parasites associated with a variety of vertebrate and invertebrate hosts. despite their importance as causative agents of severe mortality outbreaks in farmed aquatic species, little is known about their life cycle and their host range. the present work reports the characterization of "candidatus cryptoprodotis polytropus," a novel rickettsia-like bacterium associated with the common ciliate species ps ... | 2009 | 19457052 |
