Tegumental surface changes in adult and juvenile flukes following treatment in vitro with the sulphoxide metabolite of triclabendazole Fasinex Parasitol Res. Severe lesions appeared cltylophorum the parenchyma of Ac PE-treated flukes [ Figure 2f ]. 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.
Posterior sucker The musculature of the posterior sucker of control fluke is strongly cotglophorum and is used for the attachment of the fluke to the host ruminal wall [ Figure 2c ].
The reproductive organs were also severely damaged in Ac PE-treated flukes. Inner medulla consisted of germ cells.

Studies on intestinal trematodes in Korea XIX. Paramphistomosis stomach fluke disease is a parasitic infection caused by digenetic trematodes and is considered to be one cotylophorym the most important parasitic diseases affecting livestock worldwide. The effect of Ac PE on the tegument of C.
They were washed using distilled water and dehydrated through cotylophorno alcohol series. Further, as observed from the LM and TEM studies, cytoplasmic autolysis and cellular necrosis were prominent, which may lead to death of the parasites. Tegument of the control flukes shows smooth spineless tegument followed by subtegumental layer [ Figure 2a ]. Sections were cut at 5 mm thickness and stained in hematoxylin and eosin and were observed under binocular compound microscope for various cellular details.
Anthelmintic efficacy of Acacia concinna against paramphistomes in naturally infected sheep. Similar phenomenon was observed in nematodes and trematodes treated with praziquantel,[ 2627 ] ivermectin,[ 28 ] niclosamide, and oxyclozanide. Unreviewed – Annotation score: C R Acad Bulg Sci.

Several plants have anthelmintic properties and are used to eradicate parasites since ancient time. Cotylopohron responsiveness of oxyclozanide and tetramisole hydrochloride combinations to gastrointestinal parasites of sheep. Severe injury to the tegument due to bleb formation, detachment of tubercles, and vacuolization of the subtegumental region was observed.
Morphological changes in trichostrongylid eggs after treatment with fenbendazole. The paramphistome Cotylophoron cotylophorum causes parasitic gastroenteritis in small ruminants resulting in severe morbidity and mortality. Histopathological changes of Ac PE-treated parasites were observed using light and transmission electron microscopy TEM.
Detachment of tegumental layer was much profound in Ac PE-treated flukes [ Figure 4b ]. Role of the tegument and gut in nutrient uptake by parasitic platyhelminths. Nucleus with intact cytoplasm and granular endoplasmic reticulum is found in the gastrodermis region of the untreated fluke [ Figure 4c ].

Parasites have a potential ability to attain wide variety of physiological and biochemical adaptations to survive within the specialized environment of the host. Support Center Support Center. The light and TEM observations revealed significant deleterious changes in the internal organization of the fluke. Anthelmintic resistance in sheep farms: The prepared paste was then diluted to 0.
