“…The possible explanation could be hypoalbuminemia and decrease in intravascular osmotic pressure, which allowed fluids accumulation within the abdominal and thoracic cavities (Braun, 2009;Mohamed, 2012). That concurs with Edith et al (2012) who demonstrated that hypoalbuminemia is a marked syndrome in the chronic phase of liver fluke infection.…”

Regular updating of our knowledge on the epidemiological determinants of bovine fascioliasis is necessary to increase the awareness of the disease's significance and subsequently, improve the control measures. The objectives of this study were (1) to estimate the prevalence of bovine fascioliasis, and identify the association of epidemiological characteristics under traditional householders' production systems, (2) to describe the association between the clinical picture, Fasciola spp. egg count and hepatobiliary ultrasonography findings. In total, 270 faecal samples were examined microscopically for the presence or absence of Fasciola spp. egg, using the sedimentation-flotation method. Copro-positive animals were subjected to ultrasonographic examination. Overall prevalence of copro-positive animals was 27.4% (22.4-33.0%, 95% CI). The final multivariate analysis showed that there was a significant association between fascioliasis and animal species (P < 0.03), and administration of anthelmintic (P < 0.0001). Cattle have a less chance of being positive to Fasciola spp. by 0.55 (95% CI: 0.30 - 0.99) compared to water buffaloes. Administration of anthelmintic to animals on a regular basis decreased the risk of copro-positivity to Fasciola spp by 0.17 (95% CI: 0.07 - 0.36) compared to animals received anthelmintic on an irregular basis. Infected animals having different Fasciola spp. egg burden revealed different clinical symptoms associated with hepatobiliary changes on ultrasonographic examination ranged from normal hepatic parenchyma and bile system in low faecal egg load to hyperechogenic hepatic parenchyma, hyperechogenic with distal shadowing bile duct, and distended gallbladder in high faecal egg load of Fasciola spp. In conclusion, the prevalence of bovine fascioliasis is high under the traditional household's production system. Regular administration of anthelmintic significantly reduces the animal's chance of being copro-positive to Fasciola spp. Ultrasound poses a valuable prognostic technique for assessment of bovine fascioliasis.

“…In large ruminants, including buffalo, anaemia and hypoalbuminaemia are being the most common and glaring manifestations, consistent of the fasciolosis (Kumar et al 1982;Ganga et al 2007;Edith et al 2010b). The developing F. gigantica juveniles and the adults have been considered non-haematophagous and tissue feeding parasites yet cause severe anaemia in the host suffering from acute and/or chronic disease (Ganga et al 2004b).…”

“…Various factors, such as haematophagia, haemorrhages during migratory phase and injurious nature of the fluke metabolites discharged into the host circulation significantly contribute to the development of anaemia (Ganga et al 2004a). Buffalo calves, suffering from the acute course of the disease, with mean fluke load of 300 and above had a significant fall in erythrocytic indices during late prepatency caused normocytic normochromic anaemia (Yadav et al 1999b;Ganga et al 2007), whereas in the chronic phase, hypoalbumineamia is more marked than anaemia and an immune carrier host, on partial recovery from the acute course of the disease, continues to suffer from normocytic hypochromic anaemia (Edith et al 2010b). …”

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.
