| leech mycetome endosymbionts are a new lineage of alphaproteobacteria related to the rhizobiaceae. | mycetomal organs attached to the esophagus of hematophagous leeches which are known to harbor endosymbiotic bacteria were removed from three species in the leech family glossiphoniidae. anatomical observations indicated that placobdellid mycetomes are paired and caecate, inserting into the esophagus posterior to the proboscis. light and electron microscopy demonstrated that there is a single layer of mycetome epithelial cells harboring gram-negative rods and that these epithelial cells are ultra ... | 2004 | 15022768 |
| removal of organic load from olive washing water by an aerated submerged biofilter and profiling of the bacterial community involved in the process. | the present work aims to use a biofilter technology (aerated submerged filters) for the aerobic transformation at laboratory-scale of olive washing water (oww) generated in the first steps of olive oil processing, as well as the genetic profiling and identification to the species level of the bacteria involved in the formation of the biofilm, by means of tgge. chemical parameters, such as biological oxygen demand at five days (bod5) and chemical oxygen demand (cod), decreased markedly (up to 90 ... | 2007 | 18051300 |
| Phylogenomics of Reichenowia parasitica, an Alphaproteobacterial Endosymbiont of the Freshwater Leech Placobdella parasitica. | Although several commensal alphaproteobacteria form close relationships with plant hosts where they aid in (e.g.,) nitrogen fixation and nodulation, only a few inhabit animal hosts. Among these, Reichenowia picta, R. ornata and R. parasitica, are currently the only known mutualistic, alphaproteobacterial endosymbionts to inhabit leeches. These bacteria are harbored in the epithelial cells of the mycetomal structures of their freshwater leech hosts, Placobdella spp., and these structures have no ... | 2011 | 22132238 |
