Pathology of infection with Paramphistomum ichika wai in sheep

International Journal for Parasitology, 1994
Lambs were given 40,000 or 50,000 metacercariae of Paramphistomum ichikawai by injection into the rumen and necropsied at 21, 42 and 84 days after infection. Pathological changes were observed grossly and confirmed histologically in the small intestine and rumen.

Seasonal trends of Paramphistomum cervi in Tabasco, Mexico

Veterinary Parasitology, 2003
Thirty rumens were examined every month from May 1989 to April 1992 to establish seasonal trends of infection and their relationship to the climatic factors caused by Paramphistomum cervi in cattle. The cattle were chosen from three municipalities of the Sierra region in Tabasco: Jalapa, Tacotalpa and Teapa. P.

Reliability of coprological diagnosis of Paramphistomum sp. infection in cows

Veterinary Parasitology, 2007
A modified MacMaster method was tested to check its reliability for the diagnosis of bovine paramphistomosis in France. A total number of 148 fecal samples from cows examined post-mortem were analysed. Coprological results were in accordance with necropsic examinations. Bayesian techniques (Markov Chain Monte Carlo) were used to estimate the diagnostic

Molecular identification of the rumen flukes Paramphistomum leydeni and Paramphistomum cervi in a concurrent infection of the red deer Cervus elaphus

Journal of Helminthology, 2016
AbstractParamphistomosis, caused by paramphistomid flukes, is a gastrointestinal parasitic disease of domestic and wild ruminants. Originally thought to be limited to the tropics and subtropics, the disease has recently been reported in temperate regions.

The susceptibility of lymnaeid snails to Paramphistomum cervi infections in Mexico

Veterinary Parasitology, 1990
The occurrence of Paramphistomum cervi has been reported in Mexico, but its intermediate hosts have not been identified. Five species of snails of the genus Lymnaea, L. bulimoides, L. columella, L. cubensis, L. humilis and L. palustris, were collected in Mexico. Only three of the exposed species, L. palustris, L. cubensis and L.

Paramphistomum cervi: Surface topography of the tegument of adult fluke

Experimental Parasitology, 2010
Adult Paramphistomum cervi or rumen fluke are pear-shaped, slightly concave ventrally and convex dorsally. The worm measures about 5-13 mm in length and 2-5 mm in width across the mid-section. As observed by scanning electron microscopy (SEM), the tegumental surface in all part of the body, appears highly corrugated with transverse folds alternating ...

Phosphatase systems in Paramphistomum explanatum Fischoeder, 1901

Zeitschrift f�r Parasitenkunde, 1975
Extracts of adult Paramphistomum explanatum have been shown to contain high concentration of acid phosphomonoesterase with maximum activity at pH 4.5. The enzyme has been characterized by an exhibition of an unexpected increase in the inhibitory action of a mercury at 1 mM concentration by EDTA.

Molecular identification of Paramphistomum leydeni and Paramphistomum cervi in red deer (Cervus elaphus) in Croatia

2016
Paramphistomosis of domestic and wild ruminants is caused by rumi-nal flukes from Paramphistomum genus (Trematoda: Digenea) that parasitize in fore stomachs as adults and in intestines as juveniles, and may cause major economic losses. Given their worldwide distribution and indications that in-fections are becoming more common it seems that the ...

[What is Paramphistomum cervi?].

Angewandte Parasitologie, 1984
It is proved histologically that lacking of tegumented papillae in Paramphistomum cervi is based on the alteration of the tegument furnished with papillae in the normal state. The differences in the dorsal extension of the vitellaria, in the histological structure of the genital opening complex and in other features, used by Eduardo (1982) for the ...
