A study was conducted to determine the presence of zoonotic parasite (Fasciola hepatica) in drinking water sources of five different areas madina colony, islamiacolony, deyal road, zafrabad colony and dikhan city in district D.I. Khan, Khyber Pakhtunkhwa and their zoonotic potential. A total of 200 water samples were collected from the three different sources such as tap water, pond water, drain water. The water samples were filtered through Whatt-man filter paper (USA) in water filtration assembly and the residual solid particles containing parasites were collected from the filter paper. The filtered residue was centrifuged at 4000 rpm for 5 minutes, the supernatant was discarded and the pallet was preserved in an eppendorf tubes and stored at 4 °C for further process. In the present study, overall prevalence was 5% (10/200). The presence of Fasiola hepaticain tap water was 1% (1/100), in pond water was 6% (3/50) and in drain water was 12% (6/50).
Fascioliasis is spread through contamination of water sources and cause morbidity throughout the world. In the current study 300 water samples were processed by PCR for detection of Fasciola hepatica. The overall prevalence in different water sources was 9.66 % (29/300). Highest prevalence was recorded in drain water16 % (16/100) followed by tube well water 10% (4/40), open well water 8 % (8/100) and the lowest was recorded in tap water 1.66 %(1/60). The significant difference P < 0.05 was recorded during data analysis. The highest prevalence was recorded in summer. It was concluded from the study that cleaning and filtration should be adopted to avoid the health hazards against water borne zoonotic parasites.
CIAS detection of Fasciola hepatica/F. gigantica intermediate forms in bovines from Bangladesh
Acta parasitologica / Witold Stefański Institute of Parasitology, Warszawa, Poland, 2016
Fascioliasis is an important food-borne parasitic zoonosis caused by two trematode species, Fasciola hepatica and Fasciola gigantica. The characterisation and differentiation of Fasciola populations is crucial to control the disease, given the different transmission, epidemiology and pathology characteristics of the two species. Lineal biometric features of adult liver flukes infecting livestock have been studied to characterise and discriminate fasciolids from Bangladesh. An accurate analysis was conducted to phenotypically discriminate between fasciolids from naturally infected bovines (cattle, buffaloes) throughout the country. Morphometric analyses were made with a computer image analysis system (CIAS) applied on the basis of standardised measurements and the logistic model of the body growth and development of fasciolids in the different host groups. Since it is the first ever comprehensive study of this kind undertaken in Bangladesh, the results are compared to pure fasciolid ...
Human fascioliasis by Fasciola hepatica: the first case report in Nepal
Background: Fascioliasis is a zoonotic disease caused by Fasciola species. Patient may be asymptomatic or presents with jaundice and biliary colic or right hypochondriac pain due to bile duct obstruction with gastrointestinal symptoms. Case presentation: We report a case of human fascioliasis in a 45 years old female presented to Tribhuvan University Teaching Hospital (TUTH), Kathmandu, Nepal on August, 2015 with fever, right hypochondriac pain, jaundice and occasional vomiting with anorexia for 4 months whose alkaline phosphatase was elevated and peripheral blood smear revealed eosinophilia. The patient also gives the history of consumption of watercress. Endoscopic Retrograde Cholagiopancretography (ERCP) showed the presence of a flat worm resembling Fasciola hepatica and stool routine examination revealed ova of F. hepatica. The patient was treated with nitazoxanide by which she got improved. Repeat stool examination 2 weeks after treatment revealed no ova of F. hepatica. Conclusions: Patient with fascioliasis can be simply diagnosed with stool routine microscopy and treated with nitazoxanide. So patient with right hypochondriac pain, sign and symptoms of obstructive jaundice, eosinophilia and history of watercress consumption should be suspected for fascioliasis and investigated and treated accordingly.

The two species common of liver fluke, Fasciola hepatica and Fasciola gigantica, cause human fascioliasis. Hybrids between these species, and introgressed forms of Fasciola, are known from temperate and subtropical regions of eastern Asia. Here, we report the presence of hybrid and/or introgressed liver flukes in Vietnam where it has recently been recognised that human fascioliasis is an important zoonotic disease. Specimens examined came from domestic stock (cattle and buffalo) at slaughter and also from human patients. DNA sequences were obtained from the nuclear ribosomal second internal transcribed spacer (ITS-2) and from portions of two mitochondrial protein-coding genes. Mitochondrial sequences in every case were similar to those of Fasciola gigantica. Nuclear ITS-2 sequences belonged to one or other of the Fasciola species, or, sequences from both were found in the same individual worm. This study extends the known range of hybrids or introgressed forms of Fasciola into tropical regions of Asia. Ó
The diagnosis of a 22 year-old male patient from Kerabari, Morang District, Nepal led to the review of human fascioliasis cases and analysis of the epidemiological situation in that country not included in the WHO fascioliasis map. Symptom onset one month before egg detection and normal levels of ALT and AST did not agree with the 3–4-month migratory period of fascio-liasis. A shorter acute phase may happen when the main biliary duct is reached by the migratory juveniles directly from the intestinal lumen. The causal agent was ascribed to F. gigantica-like worms after considering adult fluke morphology, altitude of the patient's infection area, fasciolid characteristics in the neighbouring Bangladesh, and lymnaeid snail vector species known in Nepal and in the patient's infection area. Previous reports of human infection by Fasciola in Nepal are reviewed. The patient in question proved to be the twelfth case and the first in whom a F. gigantica-like infection is reported. In Nepal, the wide geographical distribution of livestock fascioliasis, with high prevalences in buffaloes, cattle and goats, and the reports of Fas-ciola-infected schoolchildren close to the capital Kathmandu, give rise to concern on the situation in remote rural areas in a country where most of the population lives in rural areas. Moreover, the climate change impact in Nepal remembers Pakistan, where human fascioliasis emergence has been related to climate change and man-made irrigation. All in all, the present analysis suggests that human infection by Fasciola may be underestimated in Nepal.
An Autochthonous Human Case of Fasciolopsiasis in Nepal
The Korean Journal of Parasitology
Fasciolopsiasis is rarely known as the parasitic disease in Nepal. Herein, we report a case of fasciolopsiasis in a 22-year-old man who was admitted in the hospital with abdominal pain, distension and loss of appetite for a month. He had previously diagnosed with acute viral hepatitis but, his abdominal pain was not resolving despite improvement in his liver function and general condition. During endoscopy an adult digenean worm was seen in the first part of the duodenum. After isolation, the worm was identified morphologically as Fasciolopsis buski. Microscogic examination of the patient's stool revealed eggs with a morphology consistent with F. buski. Eggs were yellow-brown, ellipsoidal, unembmbryonated, operculated, filled with yolk cells, with thin shell and ranging 118-130 µm in length and 60-69 µm in width. The abdominal pain of the patient was resolved after treatment with praziquantel. By the present study, it was confirmed for the first time that fasciolopsiasis is indigenously transmitted in Nepal. Accordingly, the epidemiological studies in humans and reservoir host animals should be performed intensively in near future.
Morphological Study of Fasciola Parasites Isolated from Cattle and Sheep in Golestan Province (Iran)
Novelty in Biomedicine, 2017
Background: The genus Fasciola parasite causes fascioliasis infection. Fascioliasis is widespread all around the world and it is finding in abundance in the northern provinces of Iran. Cattle and sheep are the main hosts of the Fasciola parasite and intermediate hosts are lymnaeid snails such as Galba and Fossaria. Two main species of this genus are F. hepatica and F. gigantica. One of the most important methods of diagnosing this worm is morphological method. The aim of this study is to identify Fasciola through the morphological method in Golestan province. M aterials and Methods: Fasciola worms taken from infected livestock livers were washed three times with PBS and were stained with carmine alum. After staining using Valero و and Periago Periago methods, the worms were measured morphologically by و بcalibrated میکروسکوپ microscope, واستریومیکstereomicroscope, and True Chrome II camera. SPSS version 19 was used for analysis of the data. R es ults: A total of 45 livers from inf...
Prevalence of Parasitic Diseases in Four Blocks of Bankura District, West Bengal
– The present work was conducted to isolate and identify different parasites from Indian Major Carps (IMC). During the study period the Severity of Infection and Parasitic Frequency Index (PFI, %) were also estimated in relation to months, seasons and developmental stages of fishes. For investigative purpose 4 different blocks namely Simlapal, Bishnupur, Taldangra and Onda of Bankura districts of West Bengal were selected considering the potential of fishery resources. Approximately 500 fishes were observed during the entire period of observation between January 2014 to December 2015. The parasite infested fishes were found to suffer mainly from respiratory manifestations, blackness of the skin and mortalities. The parasitic infestations were found to be the major problem and the most prevalent disease causative agents among cultured fish spp. All parasites were isolated from gill, fins and body surface of the fishes. The isolated parasites were Myxobolus sp., Thelohanellus sp., Dactylogyrus sp., Argulus sp. and Lernea sp. During the study period, among these parasites Myxobolus sp. showed the highest severity and prevalence (PFI, 33%) in winter months compared to it's zero prevalence in summer. Fry and fingerlings were more susceptible to Dactylogyrus sp., may be due to poor immune power compare to adult fishes. Severity and prevalence of Dactylogyrus sp. is high (PFI, 31.2 %) in summer and rainy season. Remaining all parasites were found throughout the year and adult fishes were found to be more infested with these parasites compare to fingerlings.
