Background and Aim: Dicrocoelium dendriticum or small liver fluke often causes unnoticed clinical manifestations in cattle. For a live animal, its diagnosis is mainly based on the detection of eggs by coproscopic examination. The objective of this study was to determine the presence or absence of Dicrocoelium spp. never previously reported in the study area but also to establish its prevalence, as well as an association between dicrocoeliasis and sex, age and season of the year, and histological characteristics. Materials and Methods: The study was carried out in slaughterhouses of three districts (Bouira, Tizi-Ouzou, and Bejaia) from January 2017 to December 2017. To this end, of 4053 cattle, representing more than 10% of the total number of animals slaughtered, stool and bile samples were collected and a liver inspection was carried out to investigate lesions of distomial cholangitis. They were processed for histological analysis. The specimens were morphologically identified according to the orientation of the testicles, the length and width of the body, and the level of the maximum width of the body. Results: The total prevalence of dicrocoeliasis obtained of the 4053 cattle inspected is 0.52% with a prevalence of 0.66% in Tizi-Ouzou, 0.54% in Bouira, and 0.27% in Bejaia. About 0.52% of livers had distomial cholangitis (21 of the 4053 livers examined had adult D. dendriticum and 15% had non-distomial cholangitis. About 0.25% of cattle had D. dendriticum eggs in the stool versus 0.52% of cattle had parasite eggs in the bile. Statistical analysis revealed no significant association between dicrocoeliasis infection and the season of the year (p>0.05). However, a significant association was found between dicrocoeliasis infection and sex and age of the animal (p<0.05); females and older animals are more likely to have dicrocoeliasis. Histological analysis of the fluke revealed an anterior positioning of the testicles with a slightly oblique tandem orientation, an average body length of 3.69 mm and an average body width of 1 mm. The maximum body width level is either in the middle of the fluke body or in the rear position. Conclusion: The histological study confirms that the collected fluke is D. dendriticum. Thus, this work reveals for the 1st time in Algeria the presence of D. dendriticum in three districts (Bouira, Tizi-Ouzou, and Bejaia). The results indicate that many cattle farms in the North Central Province of Algeria are infested with D. dendriticum.

“…These parasites have considerable medical, veterinary, and economic complication worldwide [ 11 , 22 , 25 ]. Iran is an important endemic focus of hydatidosis and liver flukes [ 8 , 12 , 13 , 23 , 26 - 28 ]. Various studies on cystic echinococcosis, which have been carried out in Iran, showed that the infection is generally found in sheep, cattle, goats, camels, and human [ 2 , 29 - 33 ].…”

Background and Aim:Cystic echinococcosis, Echinococcus granulosus, and liver flukes, such as Fasciola spp. and Dicrocoelium dendriticum, are important parasitic zoonoses, where they able to cause significant veterinary, medical, and economic problems. The present study was carried out to obtain the updated knowledge on the frequency of hydatidosis, fasciolosis, and dicrocoeliosis in the slaughtered sheep and cattle.Materials and Methods:Information were collected from meat inspection records using systematically visual inspection, palpation, and incision of the visceral organs in the industrial abattoir in Tehran, the capital of Iran, between February 1, 2015, and January 31, 2018. For an analysis of the data, SPSS version 16 was applied.Results:The hydatidosis infection in sheep and cattle was 2.48% and 2.25%, respectively. With respect to liver flukes, 0.62% and 0.25% sheep and cattle were infected by Fasciola spp., respectively; furthermore, 2.86% sheep and 0.79% cattle were positive for D. dendriticum.Conclusion:The findings will provide considerable awareness for the future monitoring and control of these potentially important infections.

“…According to Getachew et al, (2012), the seasonal variation in prevalence rate of E. granulosus, could be associated with different factors such as; temperature change, environmental conditions and rearing patterns. Aminzare et al, (2018), recorded that the highest seasonal prevalence of hydatidosis especially lung form was seen in autumn and winter seasons.…”

Hydatidosis is a parasitic disease caused by Echinococcus granulosus. It is also among the most prevalent zoonotic diseases with special importance for public health that causes drastic financial losses in both developed and developing countries. Among Algerian governorates, M’Sila region includes an important number of sheep flocks. Thus, an epidemiological survey was conducted on sheep hydatidosis during 5 months between December 2017 and April 2018 at three slaughterhouses of M’sila governorate, situated in municipalities of M’Sila, Boussaâda and Sidi Aissa. In parallel, an epidemiological investigation via interviews and questionnaire was conducted from March to April, 2018 on a sample of 46 sheep breeders located in M’Sila region. The questionnaire treated several risk factors (presence and deworming of dogs, informal slaughtering practices, fiability of preventive measures…etc.). Results showed a general prevalence of 24.80% among 9048 slaughtered sheep, and a seasonal prevalence higher in spring (42.02%) than in winter (21.65%) (p>0.05). Sheep of five to six years old and more are the most parasitized (p<0.0001). The lungs (38. 24%) and the livers (30.39%) were the most affected organs, while 31.24% of sheep were affected simultaneously in both organs (liver and lungs). Furthermore, females are more affected (97.99%) than males (2.01%) (p<0.0001).
