“…The infection rate of fasciolosis in sheep, goats and cattle were 7.28%, 3.37% and 10.19% respectively as shown in Table 1. The result agreed with (Kordshooli et al, 2017) in Iran, who detected that the prevalence rate of F. hepatica were 5.22% of sheep, 2.15% of goat, and 11.15% of cattle. Fasciola species are usually found in herbivores in various parts of Iraq (Hamoo et al, 2019, Raoof et al, 2020, Abdulwahed and Al-Amery, 2019.…”

“…The observation could be a return to husbandry practices and climatic variation including rain and warmth which had significant effects on the remainder of both intermediate host and the larval stages (miracidium and cercariae) of the parasite. Other factors; soil effect according to the epidemiological aspects of fasciolosis, distribute intermediate host in the environment (Kordshooli et al, 2017). In this study, The prevalence was higher in cattle, followed by sheep and goats, which may be due to free-ranged pasture grazing.…”

52 Fasciola hepatica worms (22 sheep, 3 goats and 27 cattle) from livers and bile ducts were collected. The prevalence rate of Fascioliasis was 7.28%, 3.37% and 10.19%, respectively. Among the three hosts regarding the sex, females of sheep and goats show a higher infection rate than males (4.3% and 2.25% versus 2.98% and 1.12%). Simultaneously, the prevalence rate was slightly higher in female cattle (5.28%) than male cattle (4.91%). Used the adult worms for DNA extraction followed by PCR amplification. The sequences of amplified products were identified under accession number (MT951586) of sheep were 99.51%, and (MT951587) of goat was 99.75% homologous to Iranian goat Fasciola hepatica (KF992219). Furthermore, the cattle Fasciola hepatica (MT951585) was 99.2% homologous with the reference of Iranian goat. Using phylogenetic tree analysis, isolated F. hepatica in sheep, goats, and cattle is positively related to various global F. hepatica.

“…In Iran, another study also reported a lower prevalence of Fasciola in goats and sheep compared to cattle. This observation was explained by the fact that goats consume leaves and heaths in elevated areas, sheep graze on open land, while cattle pasture near the springs and streams, and hence, cattle are at a higher risk of exposure to snail-infested freshwater [46].…”

Background Schistosoma and Fasciola are zoonotic parasites of public health and veterinary importance. However, while the epidemiology of schistosomiasis in humans is well studied, little is known about fascioliasis and schistosomiasis in livestock in Côte d’Ivoire. This study aimed to determine the prevalence and the distribution of livestock schistosomiasis and fascioliasis across Côte d’Ivoire. In 2018, we conducted a cross-sectional survey in abattoirs and farms in 13 departments of Côte d’Ivoire. In abattoirs, the mesenteric veins and livers of slaughtered cattle, sheep and goats were examined for adult Schistosoma and Fasciola flukes. Faeces from live cattle, goats and sheep were collected and examined for Schistosoma and Fasciola eggs using a sedimentation technique. Results A total of 386 cattle, 174 goats and 151 sheep from abattoirs and 435 cattle, 22 goats and 176 sheep from farms were sampled. The observed prevalence of schistosomiasis was higher in slaughtered animals. Fascioliasis was more prevalent in farm animals. The prevalence of schistosomiasis in slaughtered cattle varied between 5.9% (95% confidence interval (CI): 0.7–19.7%) and 53.3% (95% CI: 37.9–68.3%) with the highest prevalence observed in Ouangolodougou in the North. Cattle from farms had a relatively low prevalence of schistosomiasis, with the highest prevalence found in Ouangolodougou (2.4%, 95% CI: 0.7–6.1%). The prevalence of fascioliasis varied considerably from one department to another, ranging from nil (95% CI: 0.0–18.5%) to 50.8% (95% CI: 43.4–58.2%), with the highest prevalence found in farm cattle in Dikodougou in the North. Sheep and goats had a lower prevalence of schistosomiasis and fascioliasis than cattle. In slaughtered animals, cattle aged 4 years and older were at highest risk for schistosomiasis (odds ratio (OR): 2.4; 95% CI: 1.0–5.6) and fascioliasis (OR: 2.1; 95% CI: 1.1–3.9). In farm animals, male cattle had higher odds of being infected with Schistosoma (OR: 4.3; 95% CI: 0.7–26.9) than females. Conclusions Our study confirms that schistosomiasis and fascioliasis are endemic in livestock across Côte d’Ivoire. A strategic control programme should be considered, especially for cattle, including providing drinking water in troughs to reduce faecal contamination of water sources by cattle.

“…The highest rate of fasciolosis among cattle followed by sheep and lowest among goats could be due to the difference in the grazing style of animals on grassland as goats eat leaves and heaths in mountain areas, high percentage of fasciolosis among cattle may be due to that cattle were more frequently grazing near springs, pools, streams and river where naturally snails are present, hence getting more contacts with encysted metacercariae, regarding sheep they often graze on open land where getting less chance of contact with infected metacercariae and therefore the risk of their infection with fasciolosis is reduced (Kordshooli et al, 2017).…”

Fascioliasis is one of the most common neglected zoonotic disease caused by Fasciola species. The current study was conducted during January to December 2019,in which five districts were selected in various parts of Duhok governorates which differ in their environmental and geographical conditions they included: Duhok city, Zakho, Shelidiza, Aqrah and Bardarash. Each slaughter house was visited once monthly to determine the rate of fascioliasis among domestic animals; cattle, sheep and goats. The infected livers were examined grossly and the bile duct and gall bladder were inspected for the presence of Fasciola species, the work was performed in Parasitology Laboratory, Biology Dept., Faculty of Science, Zakho University. Fascioliasis was diagnosed in 2.0% (195/9757) of total slaughtered livestock, with the highest rate of infection in cattle which was 3.27% (66/2021), followed by sheep 1.76% (122/6932) and the lowest in goats 0.87% (7/804). Slightly higher prevalence rate from positive cases was found in local livestock compared to imported one (2.10% versus 1.88%). According to gender, males showed higher prevalence than females (2.08% versus 1.08%). Regarding Fasciola species, among sheep and goats; the prevalence of F. hepatica was higher than Fasciola gigantica. While among cattle, F. gigantica was the most common species. With respect to parasite burden, the heaviest burden was recorded in 38.46% (20-100 flukes/liver) of slaughtered livestock with the heaviest being in sheep (55.74%), followed by goats (71.43%) while lightest burden was recorded in cattle in 62.12% (1-10 flukes/liver). Most of the liver flukes were recovered from the bile ducts (67.69 %), followed by gall bladder (21.54%) and the least (10.77%) from both the bile ducts and gall bladder.
