Lymnaea Natalensis

This paper focuses on the geographical distribution and the habitats of Lymnaea natalensis, the snail intermediate host of the liver fluke, Fasciola gigantica, as reflected by the collection sites of its 4 552 samples currently on record in the National Freshwater Snail Collection (NFSC) of South Africa. Although this species was represented in a variety of waterbodies, the majority of samples(±70%)came from rivers, brooks and dams and in 70.8% of the cases the water was described as permanent and in 71.8% as slow flowing or standing. The results of life-table studies conducted by various authors indicated that temperature should be a relatively unimportant factor in determining its geographical distribution, but that the availability of permanent water should be decisive for its presence in a given habitat. These results are in agreement with the finding that only 7.5% of the samples of this species in the NFSC were collected in habitats which were described as seasonal. Furthermore, it gives a logical explanation for the sporadic occurrence, or total absence of this species in the more arid regions of South Africa. Water impoundments and irrigation networks contribute to a large extent towards creating perennial habitats which would be suitable for L. natalensis. As intermediate host for one of the liver fluke species which already is an economic factor in South Africa, this certainly is an aspect which ought to be reckoned within the planning and construction of new irrigation schemes.

Liver Flukes

Gall bladders from 80 mature cattle infested with liver flukes were shrunken; their walls were thickened; and mucosa was raised into rugose folds, nodules and papillary projections. All contained thick bile and mature liver flukes, predominantly Fasciola gigantica and to a lesser extent Fasciola hepatica. There was an adenomatous proliferation of the lining epithelium as well as of submucosal glands forming numerous tubuloalveolar structures and cysts lined with a uniform layer of columnar epithelium. Fibrous stroma was more than normal, and there was a mild to heavy infiltration by inflammatory cells. Some bladders had many enterochromaffin cells in the epithelium lining the glandular structures. Mitotic figures were rare, and there was no evidence of malignancy. The condition is inflammatory and hyperplastic and is believed to be common in cattle infested with liver fluke. The clinical effects of this condition have not been studied.

Liver fluke infections is an important parasitic disease that common attack cattle, buffalo and others ruminant. The disease in the tropics is caused by Fasciola gigantica trematodes. Fasciolosis found in Bali cattle besides causing high economic loss also has the opportunity infect humans. This study aims to determine the pathology changes of Bali cattle hepatobiliary system infected by F. gigantica. In January 2019 were examined a hundred of liver tissue Bali cattle. Based on the sex as many as 75 bali cattle are cows and 25 are bulls. On macroscopic examination was found fifteen bali cattles in gallbladder containing of F. gigantica. In positive Fasciolosis the surface of liver look uneven with enlargement of lymph nodes. The tissue of Bali cattle liver infected with F. gigantica is cut into 1x1x1 cm and put in a pot that has been filled with 10% neutral buffered formaline. The fixed tissue then processed in a tissue processor and stained with hematoxylin-eosin (HE). Microscopic examination was found bile ducts proliferation and blocked of the lumen accompanied by cholangio cirrhosis. Found longitudinal pieces of Fasciola gigantica liver fluke surrounded by fibrous connective tissue and multifocal coagulative necrosis with fibroblast proliferation. In some location the infiltration of neutrophil cells around the bile ducts can also be seen. Congestion, bleeding, and neutrophil infiltration are also seen in areas of necrosis. In the bile duct wall bleeding, adenomatus hyperplasia, infiltration of mononuclear cells with mild intensity and foci of calcification are found. It can be concluded that there was a change with severe intensity accompanied by chronic inflammation in the hepatobiliary system of Bali cattle with Fasciolosis.
