“…But there are larval forms of these trematods in small intestine while generate pathologic changes there. The pathology of amphistome infection has been systematically studied in goats and sheep (Horak and Clark 2000;Singh et al 1984;Rolfe et al 1994). In present study, in addition to pathologic lesions of Paramphistomum the prevalence and frequency evaluated as well.…”

There are numerous reports of clinical Paramphistomosis in ruminants caused by a variety of species (Boray 2004(Boray , 1969Horak 1989) Singh et al (1984) demonstrated the progressive changes that occur in experimentally infected goats with P. cervi (Singh et al 1984).…”

Prevalence and pathological study of Paramphistomum infection in the small intestine of slaughtered ovine

et al. 2013

Paramphistomiasis, a trematode infectious disease in ruminants, has been neglected but has recently emerged as an important cause of productivity loss. The small intestine of slaughtered sheep was collected weekly from abattoirs (Kermanshah, Sanandaj, Tabriz and Urmia Slaughterhouses) to monitoring the seasonal occurrence of Paramphistomosis, 2,421 sheep carcasses (743 male (30.69 %) and 1,678 female (69.31 %)) were examined, out of which 0.041 % were positive for Paramphistomum infestation. Furthermore, upon evaluation Paramphistomum termatodes, Gastrothylax crumenifer and Cotylophoron detected as well. Overall, the small intestinal infestation by such parasite was 0.041 % which contained hyperemia, severe congestion and haemorrhage. The highest infection in the sheep infected with Paramphistomum spp. was found during the summer (July to August) (6.7, 2 %) and followed by the autumn seasons (November to October) (3.8, 2.3 %). Microscopic study of the small intestine revealed dilatation of intestinal glands, destruction of superficial glands, replacement of fibrin, diffuse infiltration of inflammatory cells and fibrinonecrotic enteritis. Other changes as congestion hemorrhage and nodules of Ostertagia were observed in total examination of small intestines. According to statistical analysis by SPSS software and Chi square test revealed that there is significant difference between pathologic changes, seasons and ecological situations of the region (p \ 0.05). There was no significant difference between age, gender and sample pH of examined sheep (p [ 0.05).According to the results of pathologic changes of sheep small intestines, preventive measurements in the area should be taken to decrease the damages, so applying a parasitic control program is recommended.

“…The immature flukes are plug feeders in the upper part of small intestine and cause haemorrhage, resulting into anaemia, loss of weight gain and decreased production (Soulsby 1982;Singh et al 1984). In the Indian subcontinent, immature paramphistomosis of domestic ruminants ranks next to fasciolosis and the mortality can reached up to 30 % in cattle or 75 to 88 % in sheep and goats (Dutt 1980;Choudhury 1994;Agrawal 2003).…”

Epidemiology of paramphistomosis in sheep and goats in Jammu, India

et al. 2013

View full text Add to dashboard Cite

Epidemiology of paramphistomosis in sheep and goats was studied using field and abattoir samples at Jammu, India. Abattoir examination revealed that 36.2 % of sheep and 30.9 % of goats were positive for paramphistomosis. The mean worm counts (±SEM) were 23.5 ± 5.7 in sheep and 19.9 ± 3.5 in goats. On coprological examination, 16.3 % of sheep and 13.6 % of goats were found positive for paramphistomosis. The mean egg counts (±SEM) were 4.4 ± 2.6 in sheep and 3.6 ± 2.1 in goats. Season was found to have a significant (p \ 0.05) influence on the prevalence of paramphistomosis. A higher percentage of animals were found positive in rainy and post-rainy seasons as compared with summer and winter seasons. The distributions of eggs and adult flukes were significantly (p \ 0.01) different among seasons. The prevalences observed according to age and sex of sheep and goats were not significant. The study conclude that the late summer months are major risk period for paramphistomosis in the pasture grazing sheep and goats and the administration of an efficient anthelmintic in May-June and September-October should be strongly recommended to reduce the infection and minimise the perpetuating financial losses to animal owners in the region.
