“…This well-known organism has been reported on numerous occasions from sites all over the world and thus its identity is relatively easy to establish (Stein, 1867;Kahl, 1932;Suzuki, 1954;Bhandary, 1962;Cela, 1972;Dragesco & Dragesco-Kernéis, 1991;Lee & Shin, 2009). The Qingdao population corresponds closely with both the original report (Stein, 1867) and the redescription by Kahl (1932) in terms of its bright pink coloration and the pinkish cortical granules, general morphology, pattern of ciliature, possession of two macronuclear nodules, and habitat ( Fig.…”

The morphology and phylogeny of three heterotrich ciliates, Anigsteinia clarissima (Anigstein, 1912) Isquith, 1968, Blepharisma penardi sp. nov., and Blepharisma undulans Stein, 1867, were investigated based on living morphology, infraciliature, and small subunit (SSU) rDNA sequence data. The new species B. penardi sp. nov. is recognized by the following combination of characters: size about 150-180 × 45-55 μm in vivo, cell colour variable from colourless to pale pink to dark brownish; peristome extending to middle of body; 36-63 adoral membranelles; 24-34 somatic kineties; single macronucleus; cortical granules tiny and colourless; freshwater habitat. Anigsteinia clarissima and B. undulans are both reported from China for the first time and are redescribed based on a combination of previous descriptions and new data from the Chinese populations. Phylogenetic analyses based on SSU rDNA sequence data show that B. penardi sp. nov. and B. undulans are both located within a clade comprising only congeners, thus supporting the monophyly of the genus Blepharisma. Anigsteinia clarissima clusters with its only congener forming a clade that is sister to the Spirostomum assemblage. Both the morphological and the molecular data support the placement of Anigsteinia in the family Spirostomidae.

Suspensions of Blepharisma intermedium were fed latex particles for 5 min and then were separated from the particles by filtration. Samples were fixed at intervals after separation and incubated to demonstrate acid phosphatase activity. They were subsequently embedded and sectioned for electron microscopy. During formation of the food vacuole, the vacuolar membrane is acid phosphatase-negative. Within 5 min, dumbbell-shaped acid phosphatasepositive bodies, possibly derived from the the acid phosphatase-positive Golgi apparatus, apparently fuse with the food vacuole and render it acid phosphatase-positive. A larger type of acid phosphatase-positive, vacuolated body may also fuse with the food vacuole at later stages. At about 20 min after formation, acid phosphatase-positive secondary pinocytotic vesicles pinch off from the food vacuoles and approach a separate system of membrane-bounded spaces. By 1 hr after formation, the food vacuole becomes acid phosphatasenegative, and the undigested latex particles are voided into the membrane-bounded spaces. The membrane-bounded spaces are closely associated with the food vacuole at all stages of digestion and are generally acid phosphatase-negative. Within the membrane-bounded spaces, dense, pleomorphic, granular bodies are found, in which are embedded mitochondria, paraglycogen granules, membrane-limited acid phosphatase-containing structures, and Golgi apparatuses. The granular bodies may serve as vehicles for the transport of organelles through the extensive, ramifying membrane-bounded spaces.

“…In 1954, Suzuki separated B. undulans Stein, 1867 as three subspecies under Blepharisma undulans (B. undulans americanus, B. undulans japonicus and B. undulans undulans) by Ma shape as well as performance in division. These three subspecies were elevated to the specific status as a species by Bhandary (1962).…”

“…Suzuki (1954) paid attention to the taxonomic confusion and proposed three subspecies of B. undulans : B. undulans undulans, B. undulans americanus and B. undulans japonicus mostly based on the nuclear behavior in division, as well as vegetative macronuclear configuration. After then, Bhandary (1962) elevated these three subspecies to species level and primarily emphasized the shape and size of macronucleus, body size, nuclear division, and conjugation.…”
