“…Depending on the number of parasite, the intensity of egg excretion will be different. The higher the number of parasites, the greater the amount of egg excretion (Manga-Gonzalez & Gonzalez-Lanza 2005). According to the parasite life stage, it takes a long time for the egg to appear in feces.…”

From economical point of view, Dicrocoelium Dendriticum (D. dendriticum) causes a lot of damages to the livestock industry annually. So, the rapid diagnosis of infection is very important. The diagnosis is based on egg per count of feces (EPG) test because detection according to clinical symptoms is difficult. Since EPG is not accurate and sensitive, the serological methods become important for the diagnosis of this parasite as they are more accurate in comparison to EPG test and they are able to diagnose infection in a short time. In this study, somatic and Excretory-secretory antigens (EsAg) were isolated. The ELISA test was set up according to positive and negative sera and the results which were obtained compared to those obtained by the EPG test. The prevalence of infection in 550 samples by ELISA and EPG methods were 56% and 7% respectively, which shows the significant difference between these methods in examining the rate of infection. Based on the results, the specificity and sensitivity in ELISA test were 95% and 94%, respectively. The results showed that the ELISA is a more reliable test in comparison to EPG test for the rapid diagnosis of D. dendriticum infection.

Arazi koşullarında ise sıcak ayların salyangozdaki larval gelişimi hızlandırdığı tespit edilmiştir (14). Kara salyangozlarının hepatopankreaslarında yaşayan larval safhaların bu organ üzerinde etkileri olduğu tespit edilmiştir.…”

ÖZDicrocoeliosis, küçük karaciğer kelebeği Dicrocoelium spp. (Trematoda, Dicrocoeliidae)' nin geviş getiren hayvanlar ve insan da dahil diğer bir çok hayvan türünün safra kanallarında ve safra kesesinde parazitlenmesiyle sebep olduğu helminthosis bir hastalıktır. Dicrocoelium'un biyolojik yaşam döngüsünde, kara salyangozları birinci ve karıncalar ikinci ara konak olarak görev yaparlar. Kara salyangozlarının hepatopankreaslarında sporosist ve serkarya larval safhaları, karıncaların abdomen ve beyinlerinde metaserkarya larval safhası yaşamaktadır. Türkiye'de bu parazite birinci ara konaklık yapan kara salyangozları Helicopsis derbentina, H. protea, H. krynickii, Cernuella virgata, Trochoidea pyramidata

“…Regarding the prevalence rates of this fluke parasitization in herbivore animals in our country, there are some studies that report variable rates ranging between 23% and 100%. 2,4,[13][14][15] However, there is still little epidemiological data, making it difficult to know the real situation of this parasitism and to establish control guidelines to combat it. Our findings could be important for public health because of the increased relevance of uncontrolled markets, the traditional food preparation practices among the immigrant population, and the lack of veterinary control guidelines assigning potential sources of this trematode infection.…”

Abstract. Finding Dicrocoelium dendriticum eggs in human feces is exceptional and there are few prevalence data available. True infection occurs after accidental ingestion of ants containing metacercariae and spurious infection through the consumption of infected animal liver. Differential diagnosis between true and pseudo-infections is performed through stool examination after a diet free of liver. In addition, microscopy can help to differentiate the type of infection. We report six cases, all from sub-Saharan Africa, detection of this fluke at the Tropical Medicine Unit Vall d'Hebron-Drassanes (Barcelona, Spain). Dicrocoelium dendriticum transit eggs were visualized in five cases and there were no subsequent visualizations after diet, which reinforces that all these cases were false parasitism. In one case, few embryonated eggs were observed and the patient was treated for a possible true parasitism. There is a need to investigate the prevalence of D. dendriticum in our country focusing on the distinction between true and spurious infections.Dicrocoelium dendriticum, known as the lancet liver fluke, is a worldwide-distributed trematode with a complex cycle.
