“…Investigations on in vitro F. gigantica infection of L. auricularia revealed: (1) younger snails (1-4 weeks) were not suitable for in vitro infections and had higher mortality (Prasad 1989); (2) a higher intake of infection from the bubaline origin than caprine/ovine origin F. gigantica miracidia (Dhar and Sharma 1986); (3) optimum temperature for in situ development of miracidia and metacercarial production was 25°C ± 0.5°C (Dhar and Sharma 1986); (4) laboratory infected snails had a lower metacercarial production than those collected from water bodies in the nature (Sharma et al 1989); (5) positivity of snails was inversely proportional to availability of space for miracidial migration at the time of in vitro infection (Dhar and Sharma 1986); (6) cercarial production occurred in waves, with an in-between 1 and 12 days resting period(s) and floating cysts of F. gigantica were produced in the first few waves of cercarial production cycles (Dhar and Sharma 1986); (7) no development and emergence of F. gigantica cercariae from L. auricularia occurred below 12°C and above 33°C, however, a temperature of 20°C was optimum for the purpose (Sharma et al 1989); (8) an infected snail, in optimum environmental conditions during autumn months was capable of producing sufficient number of F. gigantica MC, causing acute, clinical and fatal disease in ten buffalo yearlings. On an average 204 F. gigantica MC are produced per day by an infected snail (Sharma et al 1989); (9) over 95% cercariae shedding by the infected snails were observed during night between 6 pm and 6 am next day (Gupta and Yadav 1994); (10) unlike F. hepatica, the escaping site of F. gigantica cercariae from developing rediae in L. auricularia was not confined to birth pore(s) in the rediae.…”

The freely floating cercariae could emerge out from any site of the redial elastic, acellular but sticky tegument, leaving behind a self healing indentation (Yadav et al 1997).…”

On the Indian sub-continent, nearly 5,000 years ago, the domestication of the riverine buffalo-the incredible Asian dairy animal was initiated. It plays a versatile role in socio-economic upliftment of its owners from the rural agricultural communities in Asian, African, South American and a few European countries. Comparatively, buffaloes are lesser evolved and susceptible to infectious diseases than cattle. However, poor body thermoregulation and wallowing nature predisposed them to snail borne infections, especially tropical fasciolosis-an incessant major constraint on buffalo production and improvement programmes. This review article is an insight into the global prevalence, varied epizootiological factors, offers possible explanation to pathophysiological clinical signs, deleterious effects of the tropical liver fluke, involving hepato-biliary system, haemopoitic system, endocrine glands and their secretions, oxidative stress, altered metabolism and significant fall in food conversion efficiency with unaffected digestibility of nutrients. Besides, the authors have briefly discussed and reviewed the developments and significance of successful immunodiagnostic approaches for detecting and forecasting the disease during early pre-patency and feasibility of developing a cost effective immunoprotection strategies against tropical fasciolosis.

“…In the absence of statistically and epidemiologic data, evaluating liver fluke prevalence in livestock based on liver condemnation statistics might be useful. Information about infections of cattle, sheep and goats with liver fluke in south-western Asia were reported from some countries such as Iraq (Al-Khafaji et al 2003), Pakistan (Sharma and Raina 1989), Saudi Arabia (Over et al 1992) and Turkey (Gül and Aydin 2008). An old report has only been published on prevalence of Liver fasciolosis in sheep, cattle, goats and buffaloes from Ahwaz, Iran (Ahmadi and Meshkehkar 2010), although several reports exist on those in other regions of Iran (Daryani et al 2006;Moghaddam et al 2004).…”

Fasciola spp. and Dicrocoelium dendriticum as liver flukes, contaminate ruminants and other mammalian extensively and cause major diseases of livestock that create considerable economic losses. This retrospective study has been done to evaluate contamination rate of slaughtered animals with fasciolosis and dicrocoeliosis at Lorestan abattoirs. In this survey, prevalence rate of fasciolosis and dicrocoeliosis in slaughtered animals in a 3-year period (2010-2013) has been analyzed. A total of 356,605 livestock including 265,692 sheep and 90,913 goats were slaughtered in the 3-year period and overall 39,613 (11.1 %) livers were condemned. Fascioliasis and dicrocoeliosis were responsible for 6.3 and 4.8 % of total liver condemnations in this period, respectively. Fasciola spp. and D. dendriticum infection in sheep (7.1 and 5.6 %, respectively) were considerably higher than goats (3.9 and 2.6 %, respectively). The annual prevalence rates showed a significant decline in the fasciolosis and dicrocoeliosis infection in goats (p \ 0.001). Data showed significant seasonal pattern for distomatosis in sheep and goats (p \ 0.001). Liver condemnations due to fasciolosis were prevalent in sheep and goats slaughtered during spring and autumn, respectively, whereas dicrocoeliosis were common in spring season for both sheep and goats. This survey provides baseline data for the future monitoring of these potentially important parasitic infections in the region.

“…In Turkey, the prevalence rate of fasciolosis and dicrocoeliosis were 3.99 and 23.55 % in sheep, and 0.48 and 2.65 % in cattle, respectively (Gargili et al 1999). The prevalence rate of F. hepatica in sheep and goats in Pakistan was 51.3, and 14.8 %, respectively (Sharma and Raina 1989). In a study performed in Saudi Arabia, the prevalence rate of Fasciola spp.…”

A retrospective survey of liver flukes in livestock based on abattoir data in Kermanshah, west of Iran

2014

View full text Add to dashboard Cite

A retrospective study was carried from 2008 to 2013 to estimate the prevalence of liver flukes in ruminants slaughtered at the abattoir of Kermanshah province, west of Iran. A total of 663,633 animals slaughtered in the 5-year period and totally 1.95 % of livers were condemned due to liver flukes. Fasciolosis were responsible for 0.8, 0.7 and 1.5 % of liver condemnations, whereas 1, 0.8 and 1 % of liver were condemned because of Dicrocoelium dendriticum infection in the sheep, goats and cattle, respectively. A significant difference in the prevalence of liver flukes were observed among studied animals (p \ 0.001) and the highest and lowest prevalence were detected in cattle and goats, respectively. Data showed significant seasonal pattern for distomatosis in sheep and goat (p \ 0.001). Liver condemnations due to fasciolosis were prevalent in sheep and goats and cattle slaughtered during winter, summer and autumn, respectively, whereas dicrocoeliosis were common in autumn season for sheep and cattle and in winter for goats. This survey provides baseline data for the future monitoring of these potentially important parasitic infections in the region.
