Profound damage to the eggs such as disintegration of the yolk cells was observed in Ac PE-treated flukes [ Figure 3h ].

Morphofunctional changes in the tegument and the intestinal wall of adult Fasciola hepatica under the action of oxyclozanide and VUFB Paramphistomosis stomach fluke disease is a parasitic infection caused by digenetic trematodes and is considered to be one of the most important parasitic diseases affecting livestock worldwide. One of the major sources of wool and meat production is sheep. Tegument of the control flukes shows smooth spineless tegument followed by subtegumental layer [ Figure 2a ].

Acacia concinnaanthelmintic, Cotylophoron cotylophorummorphology, paramphistome, ruminant. Journal List Trop Parasitol v. Update of the situation in the American continent. The results of the present study convincingly showed that AcPE is an effective anthelmintic causing detrimental effect to C. The walls of the testes were lined by germinal epithelium where from the spermatocytes were formed and liberated into the lumen [ Figure 3c ]. Characterization and localization of saposin-like protein-2 SAP-2 in Fasciola gigantica.

Detachment of tegumental layer was much profound in Ac PE-treated flukes [ Figure 4b ].

Morphological and histological analysis of Cotylophoron cotylophorum treated with Acacia concinna.

Preparation of plant extract Pods of A. Intestinal cecum of untreated fluke has a thin wall and large lumen. Blebs were found near the posterior sucker region of Ac PE-treated fluke with rough tegument [ Figure 1f ].


Numerous smaller blebs were observed near the oral region of Ac PE-treated fluke [ Figure 1d ]. Transmission electron micrographs of the cotylophhorum and gastrodermis of untreated Cotylophoron cotylophorum and those treated with cotylophorkn extract of pods of Acacia concinna 0. All the flukes treated with Ac PE survived till 8 h with reduction in motility compared to the control flukes.

J Appl Anim Res. Double fixation gives stability during dehydration, embedding, and also during electron bombardment. The external surface of trematodes is composed of multifunctional syncytial tegument, the major interface through which various physiological functions such as digestion and absorption take place.

The musculature of the posterior sucker of control fluke is strongly developed and is used for the attachment of the fluke to the host ruminal wall [ Figure 2c ]. EMBL nucleotide sequence database More Priya and L Veerakumari. In vitro effect of praziquantel on Paragonimus westermani by cotylphorum and scanning electron microscopic observation. Inner medulla consisted of germ cells.

It lists the nodes as they appear top-down in the taxonomic tree, with the more general grouping listed first. Severe injury to the tegument due to bleb formation, detachment of tubercles, and vacuolization of the subtegumental region was observed. The swelling of the intracellular organelles may be attributed to a change in the tegumental permeability of the apical plasma membrane of the fluke as proposed by Anderson and Fairweather in Fasciola hepatica treated with diamphenethide.

These fixed flukes were washed in distilled water and dehydrated through graded alcohol series, cleared in xylene, and embedded in paraffin wax. Integrated resource of protein families, domains and functional sites More 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.

Priya P, Veerakumari L. Severe indentation of the nucleus with vacuoles in the cytoplasm was observed in Ac PE-treated flukes [ Figure 4d ]. October 16, Last modified: Medicinal Plants of the World: Ruptured teguments with blebs were observed on the dorsal surface of Ac PE-treated flukes after 8 h of incubation [ Figure 1b ].


Numerous lesions were observed in the gastrodermis of the parasite [ Figure 3b ]. The effect of flukicidal agents on the morphological integrity of trematodes usually exhibited the tegumental distortions and vacuole formation.

An immunofluorescent study of antigenic changes in the tegument during development in the rat and the sheep. Parenchyma The parenchyma of untreated fluke appeared intact [ Figure 2e ]. Studies on intestinal trematodes in Korea XIX. Survey of Cohylophoron plants for saponins, alkaloids and flavonoids. Anthelmintic resistance in sheep farms: Intestine Intestinal cecum of untreated fluke has a thin wall and large lumen.

The posterior sucker of untreated fluke appeared smooth [ Figure 1e ]. Papers overview Semantic Scholar uses AI to extract papers important to this topic.

Morphological and histological analysis of Cotylophoron cotylophorum treated with Acacia concinna.

The tegument of the untreated fluke consists of compact tubercles, and tegumental syncytium is intact [ Figure 4a ]. Treatment of fish parasites Role of the tegument and gut in nutrient uptake by parasitic platyhelminths. Severe lesions were observed in the gastrodermis of Ac PE-treated flukes [ Figure 3b ]. Therefore, the present study aimed to investigate the efficacy of Ac PE on the surface topography and various organ systems of C.

The cotglophorum spreads internally to affect subtegumental region. Support Center Support Center. The paramphistome Cotylophoron cotylophorum causes parasitic gastroenteritis in small ruminants resulting in severe morbidity and mortality.
