Growth and survival of peritrich ciliates in an urban stream
Oecologia, 1987A computerized system was devised to trace the attachment, growth and disappearance of peritrich ciliates in an urban river. By tracing the development of each Carchesium polypinum colony in the river, it was possible to estimate the actual growth rate of this species without considering the effect of immigration. The survival and colonization rates of

Contractility and its Control in Peritrich Ciliates*†
The Journal of Protozoology, 1973SYNOPSISA review of the recent literature on the structure and physico‐chemical properties of the myoneme and its specialization, the spasmoneme, of peritrich ciliates was made. Myonemes are composed of tightly packed bundles of 3–5 nm microfibrils which parallel, more or less, the long axis of the bundle and are of indefinite length.

Colonization of non-living surfaces in streams by peritrich ciliates
European Journal of Protistology, 1993Cleaned stones or glass slides placed in streams were quickly colonized by vorticellids and Carchesium, whose numbers increased for about 2 weeks before falling to a steady level by about 4 weeks. Platycola populations developed more slowly, but tended to become dominant after 3 or 4 weeks. The populations of peritrichs on surfaces already coated with '

Growth of the Peritrich Opercularia coarctata in Axenic Culture*
The Journal of Protozoology, 1974SYNOPSISA synthetic medium for Opercularia coarctata was developed that contains 20 amino acids, 10 vitamins, an 8‐component balanced salt solution, Fe2(SO4)3·(NH4)2SO4·24H2O, Tween 80, stigmasterol, a 7‐component nucleic acid mixture, phenol red as an indicator, and 2,500 U.S.P. units/ml penicillin to maintain sterility.

Effects of Irradiation on the Peritrich Ciliates Vorticella and Telotrochidium
Transactions of the American Microscopical Society, 1976Vorticella microstoma and Telotrochidium henneguyi were exposed to doses of x- and gamma-radiation ranging from 46 r to 120 Kr. Irradiation was applied to freshly excysted motile organisms. Doses below 2 Kr did not induce noticeable morphological effects in either peritrich.

Opercularia coardata, ein variables Peritrich
Archiv für Protistenkunde, 1979Summary 1. Since the first description of Opercularia coarctata by Clapabede and Lachmann 1854 this peritrich has been described with 28 different names. 2. The zooids of Opercularia coarctata are very variable. All individuals have constant numbers of circular galleries of cils: 1¼–11½. The cils are 8–12μm long. The c.v.

Contraction of protoplasm. IV. Cinematographic analysis of the contraction of some peritrichs†
Journal of Cellular Physiology, 1970AbstractThe contraction and relaxation of Vorticella difficilis, V. campanula and Carchesium sp. were studied by high speed cinematography. In Vorticella it was shown that coiling of the stalk usually started near the zooid and spread downwards; the point of initiation bore no relation to the position of the stimulating electrodes.

A new Peritrich Ciliate from a Hypersaline Habitat in Northern China
Zootaxa, 2016A new peritrichous ciliate, Cothurnia salina n. sp., collected from a brine pond of a salt factory in Yantai, China, was investigated based on live observations, silver staining method and molecular phylogenetic analysis. The diagnosis for this new taxon: body elongated columnar, in vivo 80–98 × 12–19 µm; lorica barrel-shaped, with aboral part heavily ...
