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.

Isseroff H, Read CP. The light and TEM observations revealed significant deleterious changes in the internal organization of the fluke. Complete detachment of tegumental layer was observed in Ac PE-treated flukes [ Figure 2b ]. 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.

gst – Glutathione-s-transferase – Cotylophoron cotylophorum – gst gene & protein

The in vitro effect of AcPE on the morphology and the histology of a digenetic trematode C. Select the link destinations: This is version 11 of the xotylophoron and version 2 of the sequence.

Treatment of fish parasites Update of the situation in the American continent. 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.

For SEM studies, the control and treated parasites were washed in phosphate buffer saline pH 7. Tegument Tegument cotylophotum the control flukes shows smooth spineless tegument followed by subtegumental layer [ Figure 2a ].

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

The action of many anthelmintics is reflected in their ability to inhibit the activity of enzymes involved in carbohydrate metabolism. Conflicts of interest There are no conflicts of interest. The SEM micrograph of treated flukes showed the appearance of few blebs near the oral region and rupture of the dorsal surface of the tegument.


Veerakumari L, Priya P. 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.

Biochemistry of parasitic helminths. Laboratory evaluation of cercaricidal properties of certain plant extracts.

Indian J Anim Sci. Received Jun 22; Accepted Sep Chin Med J Engl ; The posterior sucker of the parasite is highly muscularized and is used for attachment to the host ruminal wall.

Do not show this banner again. Parasites have a potential ability to attain wide variety of physiological and biochemical adaptations to survive within the specialized environment of the host. Tegument of the control flukes shows smooth spineless tegument followed by subtegumental layer [ Figure 2a ]. The results of the present study convincingly showed that Ac PE is an effective anthelmintic causing detrimental effect to C. The prepared paste was then diluted to 0.

Anthelmintic efficacy of extract of Stephania glabra and aerial root of Trichosanthes multiloba in vitro: Eggs The eggs of the untreated flukes are oval in shape, with distinct yolk cells [ Figure 3g ].

Further, as observed from the LM and TEM studies, cytoplasmic autolysis and cellular necrosis were prominent, which may lead to death of the parasites. Anderson HR, Fairweather I. Superfamily database of structural and functional annotation More Severe injury to the tegument due to bleb formation, detachment of tubercles, and vacuolization of the subtegumental region was observed.


Light and scanning electron microscopic studies on the effects of niclosamide and oxyclozanide on Cotylophoron cotyloohoron Fischoeder, J Vet Parasitol. 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. Effect of Cotylophoro concinna on the enzymes of glucose metabolism of Cotylophoron cotylophorum Fischoeder, in vitro.

Select item s and click on “Add to basket” to create your own collection here entries max. These results suggest 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. Your basket is currently empty. One of the major sources of wool and meat production is sheep. For light microscopic LM cogylophoron, the control and treated parasites were washed in physiological saline and fixed in Bouin’s fixative for 12 h.

The Ac PE octylophorum prepared by boiling 10 g of powdered pods in mL of distilled water for 10 corylophorum under constant stirring, which was then made into a fine paste. Narosha Publication House; Scanning electron micrographs of tegument, oral sucker, and posterior sucker of untreated Cotylophoron cotylophorum and those treated with aqueous extract of pods of Acacia concinna 0. The plant is widely used in traditional system of medicine for control of pathogenic bacterial and fungal diseases.

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.
