| [the characteristics of protein hydrolysis on the digestive-transport surfaces of the cestode eubothrium rugosum and of the intestines of its host--the burbot]. | the functioning of different proteinases hydrolysing proteins in a wide ph range, most of which display activity in the alkaline zone of ph, on the digestive-absorptive surfaces of the parasite and host has been investigated. the dynamics of desorption of these proteinases from the intestine of fishes and tegument of cestodes has been studied. it has been shown that the worms possess less proteolytic activity and less capacity for adsorption of proteinases as compared to the intestines of their ... | 1991 | 1813843 |
| a molecular study of eubothrium rugosum (batsch, 1786) (cestoda: pseudophyllidea) using its rdna sequences, with notes on the distribution and intraspecific sequence variation of eubothrium crassum (bloch, 1779). | the internal transcribed spacers (its-1 and its-2) of the ribosomal dna (rdna) of fish cestodes of the genus eubothrium were sequenced. the its sequences of eubothrium rugosum were determined and compared with previously analysed congeneric species, eubothrium crassum and eubothrium salvelini. the its-1 sequences of e. rugosum and e. crassum were 535 bp long, the length of e. salvelini its-1 was 536 bp. the its-2 region was found to be 403 bp in e. rugosum and e. crassum, and 401-402 bp in e. sa ... | 2003 | 12658459 |

| [electron microscope investigation of bacteria associated with the tegument of the tapeworm species eubothrium rugosum, a parasite of the intestine of burbot]. | bacteria associated with the tegument of the tapeworm species eubothrium rugosum (cestoda, pseudophyllidea) parasitizing the intestine of burbot (lota lota) were studied using transmission and scanning electron microscopy. three morphological types of the bacteria were revealed. bacteria of the first type are localized between microtrichia and fit to them closely. bacteria of the second (gram-positive) and third (gram-negative) types are localized over microtrichia of the tegument and do not att ... | 2005 | 16134784 |
| [final stages of carbohydrate metabolism in a cestode eubothrium rugosum (cestoda: pseudophyllidea)]. | characteristics of final stages of carbohydrate metabolism in a cestode eubothrium rugosum from the burbot intestine have been studied. it is found out that in the course of in vitro incubation the worms produce lactic acid to the environment with a concomitant acidification of the medium. the rate of ph changes and lactate production eventually fell during the incubation. the medium ph being the result of helminth's metabolism varies within the normal physiological limits of the host intestine ... | 2003 | 14964850 |
| [parasites-invaders of the volga river basin: history of invasion, perspective of dispersion, possibility of epizootic]. | the fauna of fish parasites in the volga river increased by 15 species in last time. these parasites have invaded together with introduced hosts or dispersed after destruction of some physical and ecological barriers. the infusoria ambiphrya ameuri, cestode cestobothrium acheilognathi, trematodes amurotrema dombrovskajae and sanguinicola skrabini have been introduced together with their hosts. a creation of water reservoirs destroyed ecological barriers and created favorable conditions for the m ... | 2001 | 11558337 |
| [iso-osmotic regulation in cestodes from freshwater fishes]. | the content of sodium, potassium, calcium, and magnesium ions was determined in cestodes ligula intestinalis, eubothrium rugosum, and triaenophorus nodulosus. in freshwater fishes the total concentration of na, k, ca, mg ions in cestode tissue water is practically similar to that of fishes muscles and in serum. it was suggested that examined cestodes have isoosmotic regulation of the water-salt balance. | 1994 | 7816510 |
| the karyotype of eubothrium rugosum (cestoda: pseudophyllidea). | the diploid chromosome set of eubothrium rugosum contains 16 elements. the karyotype consists of three pairs of metacentric, three pairs of acrocentric and two pairs of submeta-metacentric chromosomes. their mean absolute length ranges from 2.20 to 8.80 microns. the first two pairs of large metacentric chromosomes comprise over 45% of the total complement length. | 1991 | 2040562 |
