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.

SUMMARYRisk factors related to herd and farmer status, farm and pasture management, and environmental factors derived by satellite data were examined for their association with the prevalence of F. hepatica in sheep and goat farms in Thessaly, Greece. Twelve farms (16·2%) and 58 farms (78·4%) of 74 had evidence of infection using coproantigen and serology respectively. The average normalized difference vegetation index (NDVI) of farm location for 12 months before sampling was the most significant environmental risk factor for F. hepatica infection based on high seropositivity. The risk of infection increased by 1% when the value of NDVI increased by 0·01 degree. A geospatial map was constructed to show the relative risk (RR) of Fasciola infection in sheep and goat farms in Thessaly. In addition, geospatial maps of the model-based predicted RR for the presence of Fasciola infection in farms in Thessaly and the entire area of Greece were constructed from the developed model based on NDVI. In conclusion, this study demonstrated that Thessaly should be regarded as an endemic region for Fasciola infection and it represents the first prediction model of Fasciola infection in small ruminants in the Mediterranean basin.

Fascioliasis is an infection of the trematodes of Fasciola hepatica and Fasciola gigantica which causes disease worldwide. This trematode infection commonly attacks ruminants, especially in cattle, buffalo, sheep, goats, pigs and humans, as well. This disease can cause significant economic losses in the livestock industry, mainly through death, liver damage, reduced production of meat, milk and wool, and expenses for deworming. Parasitological examination for identification of fasciola infection was carried out by visually observing fecal samples for adult worms and then examined by simple flotation (using saturated NaCl solution) and formalin-ethyl acetate sedimentation techniques. Here, we were systematically reviewed existing knowledge about sensitive and efficient fasciola observation methods for the identification of fasciola species. Four databases of articles that met the inclusion requirements were compiled for the literature review. This article was published between 2015-2020 and reports on the identification of fasciola species using one or a combination of sedimentation and flotation methods. As a result, the combined method of sedimentation and flotation has the best sensitivity and egg recovery rate (Ef) values for fasciola identification.   Abstrak Fascioliasis merupakan infeksi trematoda spesies Fasciola hepatica dan Fasciola gigantica yang menimbulkan penyakit di seluruh dunia. Infeksi trematoda ini umum menyerang ruminansia, terutama pada sapi, kerbau, domba, kambing, babi dan bisa terjadi pada manusia. Penyakit ini dapat menimbulkan kerugian ekonomi yang cukup besar dalam industri ternak, terutama melalui kematian, kerusakan hati, berkurangnya produksi daging, susu, dan wol, dan pengeluaran biaya untuk obat cacing. Pemeriksaan parasitologi untuk identifikasi infeksi fasciola dilakukan dengan mengamati sampel feses secara visual untuk cacing dewasa dan kemudian diperiksa dengan cara flotasi sederhana (menggunakan larutan NaCl jenuh) dan teknik sedimentasi formalin-etil asetat. Disini, kami meninjau secara sistematis pengetahuan yang ada tentang metode pengamatan fasciola yang sensitif dan efisien dalam identifikasi spesies fascioal. Empat data base artikel yang telah memenuhi syarat inklusi disusun untuk tinjauan literature review. Artikel ini terbit antara tahun 2015-2020 dan melaporkan identifikasi spesies fasciola menggunakan salah satu atau gabungan metode sedimentasi dan flotasi. Hasilnya, metode gabungan antara sedimentasi dan flotasi memiliki nilai sensitivitas dan nilai tingkat pemulihan telur (egg recovery rate, Ef) paling baik untuk identifikasi fasciola.

Fasciolosis is a disease caused by Fasciola gigantica (Cobbold, 1855) or Fasciola hepatica (Linnaeus, 1758) that infected ruminants and caused liver damaged and loss of productivity. To control Fasciola disease in cattle, it is necessary to consider differences in the prevalence or number of cases in various cattle breed. This research was conducted in two slaughterhouses in Batu and Pujon District, Malang Regency, East Java, Indonesia involving 50 livestock in each slaughterhouse, either beef or dairy cattle. Observation was done for 2 mo by performing liver necropsy, observing the presence of fibrosis and calcification of the bile duct, counting the number of worms and weighing the removed liver tissue. Result of this research the number of fasciolosis in Ongole and Limousin cattle (30.95 % and 35.94 %) was fewer compared to Simmental and Frisian Holstein (58.33 %). Average number of worms head–1 in each cattle breed; Limousin, Simmental, Ongole, and FH were (105, 49, 27 and 129) worms. Meanwhile, fibrosis score in each group were 1.48, 1.89, 1.33 and 1.75 respectively. It is suspected that differences in cattle breed had correlation with susceptibility towards infection. It is indicated that Limousin cattle are more tolerant against liver worm infection.
