Erection of Ibirhynchus gen. nov. (Acanthocephala: Polymorphidae), based on molecular and morphological data.
The genus Southwellina is composed of 3 described species, i.e., S. hispida (the type species), S. dimorpha, and S. macracanthus. All 3 are endoparasites of fish-eating birds that have worldwide distributions.

متن کاملIntestinal spirochetosis: morphological characterization and cultivation of the spirochete Brachyspira aalborgi gen. nov., sp. nov.
The ultrastructure of spirochetes obtained from rectal biopsies of patients with intestinal spirochetosis was studied by means of negative staining and ultrathin sectioning. The cells were sigmoidal with tapered ends, 2 to 6 microns long, with a wavelength of 2 microns. Four flagella were inserted at each end of the cells. The maximal cell width was about 0.2 microns. The spirochetes were cultu...
