Oral regeneration in the ciliate Stentor coeruleus: a scanning and transmission electron optical study.
SYNOPSIS. Elaboration of ciliated feeding organelles in the protozoon Stentor coeruleus was reinvestigated for the first time by scanning electron microscopy which gives the most realisticExpand
Trypanosoma cruzi infection of BSC-1 fibroblast cells causes cytoskeletal disruption and changes in intracellular calcium levels.
The disruption of vimentin and actin filaments of host BSC-1 fibroblast cells by Trypanosoma cruzi was investigated using a mouse monoclonal anti-vimentin antibody and rhodamine phalloidin,Expand
Presence and localization of vinculin in Giardia.
The correspondence of close contact sites with vinculin localization suggests a role for vincoxin in Giardia attachment and adherence. Expand

SYNOPSIS. An electron-microscopic investigation of gluaraldehyde-and osmium-vapor-fixed Nyctotherus cordiformis has revealed the following: (1) A thin epiplasmic layer lies directly beneath a singleExpand
Cytochrome P-450 and drug metabolism in Trypanosoma cruzi: effects of phenobarbital.
The epimastigotes of Trypanosoma cruzi hydroxylate drugs at substantial rates is paralleled by increases in free and membrane-bound ribosomes. Expand
Hemoproteins in Trypanosoma cruzi with emphasis on microsomal pigments
It is suggested that the cytochrome-P-450-linked monooxygenase system in T. cruzi may be responsible for the resistance of the parasite to antimicrobial drugs. Expand
The chondriome of selected trypanosomatids. A three-dimensional study based on serial thick sections and high voltage electron microscopy

  • 1 August 1975
The unitary nature of the chondriome of two species of trypanosomatids, Blastocrithidia culicis and Trypanosoma cruzi, has been demonstrated by utilizing serial thick-sectioning techniques combinedExpand
The Somatic and Oral Infraciliature of the Enigmatic Giliate Cyathodinium piriforme
It is suggested that a combination of fine structural and morphogenetic studies is required to elucidate both the form and the function of the several unique features of Cyathodinium and that a new understanding of these will permit resolution of the problem of the systematic status of the ciliate. Expand
Ultrastructural and other observations which suggest suctorian affinities for the taxonomically enigmatic ciliate Cyathodinium.
Data obtained strongly suggest suctorian affinities for Cyathodinium, since a number of structures or features are strikingly reminiscent of similar structures recently discovered in ciliates belonging to the order Suctorida. Expand
The cellulolytic enzyme complex of Clostridium thermocellum is very large.
The cellulolytic enzyme system bound to cellulose during the early stages of growth of C. thermocellum was resolved into two major complexes which are spherical particles with diameters of 210 A and 610 A and calculated molecular weights of 4.2 million and 102 million daltons, respectively. Expand
