In a recent paper by Krull (I), Cotylophoron cotylophorum was reported from Puerto Rico, and it was shown by experiments that in the United States a snail.

Complete detachment of tegumental layer was observed in Ac PE-treated flukes [ Figure 2b ]. Reduced responsiveness of oxyclozanide and tetramisole hydrochloride combinations to gastrointestinal parasites of sheep.

Nama HS, Bhatnagar B. This is version 11 of the entry and version 2 of the sequence. ProtoNet; Automatic hierarchical classification of proteins More One micron thick sections were cut, before trimming of the blocks for ultramicrotomy. The results of the present study convincingly showed that Ac PE is an effective anthelmintic causing detrimental effect to C.


Systems used to automatically annotate proteins with high accuracy:. In vitro effect of some anthelmintics on lactate dehydrogenase activity of Cotylophoron cotylophorum Digenea: In the present study, in vitro effect of aqueous extract of pods of Acacia concinna AcP E on the morphology and the histology of the digenetic trematode Cotylophoron cotylophorum have been investigated. Preparation and characterization of excretory and secretory antigen of Cotylophoron cotylophorum and Gastrothylax crumenifer.

Electron microscopic observations of tegumental damage in adult Schistosoma japonicum after in vivo treatment with levo-praziquantel. Bleb formation may be a result of disruption of the brush border cytoskeleton as suggested by Stoitsova cotylophotum Hymenolepis fraterna treated with colchicine.


Morphological and histological analysis of Cotylophoron cotylophorum treated with Acacia concinna

Appropriate control without the plant extract was also maintained simultaneously under same environment. Furthermore, the detailed study on the separation and structural identification of the bioactive compound responsible for the anthelmintic effect would be necessary for the structure—activity relationship.

Severe indentation of the nucleus with vacuoles in the cytoplasm was observed in Ac PE-treated flukes [ Figure 4d ].

Light and scanning electron microscopic studies on the effects cotyloohorum niclosamide and oxyclozanide on Cotylophoron cotylophorum Fischoeder, J Vet Parasitol. Please review our privacy policy. cotglophoron

Light and scanning electron microscopy of Fibricola seoulensis collected from albino rats treated with praziquantel. The in vitro effect of AcPE on the morphology and the histology of a digenetic trematode C.

The present study corroborates with the earlier reports. These results dotylophoron that the uptake of the plant extract by the parasite was not only through the tegument but also through the alimentary canal as reported by Seo et al. The present study delineated the anthelmintic potential of A.

Comparative histochemical observations on the lipids in the immature and mature stages of Cotylophoron cotylophorum Paramphistomatidae: In vitro effect of praziquantel on Paragonimus westermani by light and scanning electron microscopic observation. Vacuolization of parenchyma was also prominent [ Figure 2f ].

Similar phenomenon was observed in nematodes and trematodes treated with praziquantel,[ 2627 ] ivermectin,[ 28 ] niclosamide, and oxyclozanide. Ruptured teguments with blebs were observed on the dorsal surface of Ac PE-treated flukes after 8 h of incubation [ Figure 1b ].

A number of studies on tegumental pathology induced by anthelmintics have suggested that the drug acts to alter the permeability and osmoregularity properties of the tegument.

Four distinct tokens exist: Absorption of monosaccharides by Fasciola hepatica. The prepared paste was then diluted to 0.

Blebs were found near the posterior sucker region of Ac PE-treated fluke with rough tegument [ Figure 1f ]. It lists the nodes as they appear top-down in the taxonomic tree, with the more general grouping listed first. Photomicrographs of the tegument, posterior sucker and parenchyma of untreated Cotylophoron cotylophorum and those treated with aqueous extract of pods of Acacia concinna 0.

The action of many anthelmintics is reflected in their ability to inhibit the activity of enzymes involved in carbohydrate metabolism. Survey of Indian plants for saponins, alkaloids and flavonoids. cptylophoron

Damage to the muscles associated with posterior sucker and those associated with motility may lead to loss of attachment and subsequent expulsion of the parasites from the host’s gut. Severe injury to the tegument due to bleb formation, detachment of tubercles, and vacuolization of the subtegumental region was observed. Adult live flukes numbering to ten were incubated in 25 mL cotylophirum 0.

Parenchyma The parenchyma of untreated fluke appeared intact [ Figure 2e ]. Further, as observed from the LM and TEM studies, cytoplasmic autolysis and cellular necrosis were prominent, which may lead to death of the parasites. The light and TEM observations revealed significant deleterious changes in the internal organization of the fluke.

Structural damage of the brush border of Hymenolepis fraterna Cestoda under the action of colchicine. Journal of parasitic diseases: Narosha Publication House;
