“…The World Health Organization estimates that at least 2.4 million people in more than 70 countries are affected by fascioliasis (http://www.who.int/foodborne_trematode_infections/fascioliasis/en/). Being a multifactorial disease with limited drugs available for treatment, effective measures are urgently needed to control this important foodborne and zoonotic disease [7]. …”

Identity of Fasciola spp. in sheep in Egypt

et al. 2016

BackgroundIn Egypt, liver flukes, Fasciola spp. (Digenea: Fasciolidae), have a serious impact on the farming industry and public health. Both Fasciola hepatica and Fasciola gigantica are known to occur in cattle, providing the opportunity for genetic recombination. Little is known on the identity and genetic variability of Fasciola populations in sheep.MethodsThis study was performed to determine the prevalence of liver flukes in sheep in Menofia Province as a representative area of the delta region in Egypt, as measured by postmortem examination of slaughtered animals at three abattoirs. The identity and genetic variability of Fasciola spp. in slaughtered animals were determined by PCR-sequence analysis of the nuclear ribosomal internal transcribed spacer 1 (ITS1) and the mitochondrial NADH dehydrogenase subunit 1 (nad1) genes.ResultsPhysical inspection of the liver indicated that 302 of 2058 (14.7%) slaughtered sheep were infected with Fasciola spp. Sequence analysis of the ITS1 and nad1 genes of liver flukes from 17 animals revealed that 11 animals were infected with F. hepatica, four with F. gigantica, and two with both species. Seventy eight of 103 flukes genetically characterized from these animals were F. hepatica, 23 were F. gigantica, and two had ITS1 sequences identical to F. hepatica but nad1 sequences identical to F. gigantica. nad1 sequences of Egyptian isolates of F. gigantica showed pronounced differences from those in the GenBank database. Egyptian F. gigantica haplotypes formed haplogroup D, which clustered in a sister clade with haplogroups A, B and C circulating in Asia, indicating the existence of geographic isolation in the species.ConclusionsBoth F. hepatica and F. gigantica are prevalent in sheep in Egypt and an introgressed form of the two occurs as the result of genetic recombination. In addition, a geographically isolated F. gigantica population is present in the country. The importance of these observations in epidemiology of fascioliasis needs to be examined in future studies.

“…However, this method is not always effective because, during the rainy season, snails can move to fenced habitats and then develop in ditches made by cattle trampling [53]. For example, snail migrations over 30 m have been observed from one spring swamp, in the middle of a pasture grazed by dairy cows, to puddles at the edge of the pasture [72]. Recent studies have explored the use of very high-resolution satellite and drone imagery to map small water bodies and populations of intermediate host snails in pastures, but further research is required to make this approach operational, and to give advice that is adapted to the situation of a specific local farm [73,74].…”

“…However, the risk of promoting resistance to anthelmintics is high, because flukes would be in contact with recently treated cows. Thus, if eggs are eventually shed they will all come from resistant strains [72]. There are also some alternative methods to chemical treatments, such as deworming plants (Agrimonia eupatoria, Urtica dioica, Calendula officinali), but they must be combined with good livestock management, including the rotation of herds between pastures and safe and uncontaminated food and water iii .…”

“…First, farmers can limit the access of herds to snail habitats. It is possible to isolate herds from water sources at risk by fencing [72], and also by adding water tanks that are regularly cleaned to avoid snail invasion. However, this method is not always effective because, during the rainy season, snails can move to fenced habitats and then develop in ditches made by ca Finally, another tool for fasciolosis control is to manage herd genetic resources to enhance the resistance or tolerance to fasciolosis in livestock populations.…”

Fasciolosis is a worldwide disease caused by the liver fluke Fasciola spp. This food- and water-borne disease is a major public health and veterinary issue. It is currently (re)emerging in several regions mainly due to the rapid evolution of human activities. This article reviews the current knowledge of the impact of irrigation-system management, livestock management, and human diet and hygiene habits on the emergence of fasciolosis. We also identify the gaps in this knowledge and the possible solutions for limiting these impacts. Integrated control seems to be the most effective solution for controlling fasciolosis, because it enables monitoring, prevention, and rapid action in case of the (re)emergence of the disease.

. Wat zijn de mogelijkheden om een leverbotinfectie van melkvee te voorkomen? Wageningen Livestock Research, Louis Bolk Instituut, Rapport 1029.Samenvatting NL Infecties met leverbot zijn in toenemende mate een knelpunt in de diergezondheid van grazende (of vers gras gevoerde) herkauwers. Leverbotinfectie leidt tot ziekte met economische gevolgen en voor melkgevende dieren zijn geen anthelmintica vrij beschikbaar. In dit project is het leverbotinstrument ontwikkeld met als doel om veehouders inzicht en handelingsperspectief te geven ten aanzien van de leverbotsituatie op hun bedrijf. In dit rapport worden de resultaten van het leverbotinstrument weergegeven en van een drietal preventieve maatregelen die zijn uitgeprobeerd.Summary UK Liverfluke infections are increasingly a bottleneck in the animal health of grazing (or fresh grass fed) ruminants. Liverfluke leads to disease with economic consequences and for lactating animals no anthelmintics are freely available. This project has been working on the development of the liverfluke instrument with the aim of providing dairy farmers insight and action perspective regarding the liverfluke situation on their farm. This report presents the results of the liverfluke instrument and of three preventive measures that have been investigated.
