Medicinal plant Potentilla fulgens and its effect in vitro against Fasciola gigantica

Fascioliasis is a one of the most important serious parasitic zoonotic disease which caused by trematode giant liver fluke Fasciola hepatica and F. gigantica among cattle’s and humans. The infection of Fasciola can be control by the use of phytochemicals as anthelmintic components. The anthelmintic activities of dried root powder of medicinal plant Potentilla fulgens and their different preparations (organic extracts and column purified fraction) are uses in vitro against liver fluke F. gigantica. The dried root powder, different organic extract, and column fractions were time and concentration-dependent. Among all the organic extracts, ethanol extract was high toxic than other organic extracts. The toxic effect of ethanolic extract of P. fulgens after 2h exposure the LC50 value is 5.22 mg/ml against F. gigantica. The column purified fraction of dried root powder of P. fulgens shows more toxicity. The 2h LC50 of column purified fraction was 3.25 mg/ml whereas in 8h exposure the LC50 is 1.24 mg/ml. The phytochemicals of the P. fulgens may be used as anthelmintic components against liver fluke F. gigantica.

Prevalence of the giant liver fluke (fascioloides magna, bassi, 1875) in red deer (cervus elaphus) in the region of floodplain forests of northern Serbia

This is the first study offering insights into the prevalence of giant liver fluke in the population of red deer in the territory of Serbia. Giang liver fluke (Fascioloides magna, Bassi, 1875) is the most important liver parasite among wild ruminants in Europe, especially in the region of floodplain forests along the upper watercourse of Danube river. The main objective of this research was establishing the prevalence of giant liver fluke in the region of floodplain forests of northern Serbia. In the observed regions (hunting grounds), the population prevalence rates ranged from 0 to 80% with an average prevalence in positive herds being 70.6%. The total population of red deer, from the observed hunting grounds, exposed to the giant liver fluke includes 47.9% of red deer population in Serbia, which is 0.7% of the total hunting area of Serbia. Giant liver fluke is present in north-western regions of Serbia in a narrow area of floodplain forests along the watercourse of Danube and Sava rivers next to the border with Croatia. The red deers populating the wetland basin of “Gornje Podunavlje” migrate freely through the tri-border area of Hungary, Croatia and Serbia making a consistent epizootical unit. Moreover, the game migrates freely between Croatia and Serbia in the area of Posavina forests along the river Sava. All data obtained in this research are essential for further activities aimed at preventing the spread of this parasite within red deer population and thus decreasing consequent damages and losses.

Mitochondrial genotyping of Fascioloides magna from Bavaria, Germany

In last few years, a great effort has been made to understand genetic interrelationships of European and North American populations of giant liver fluke

A long-term survey of Fascioloides magna in red deer (Cervus elaphus) in Slovakia (Danube floodplain forests) during the period of 2005 – 2015

Summary Fascioloidosis of wild and domestic ruminants is caused by giant liver fluke, Fascioloides magna (Trematoda; Fasciolidae). In Slovakia, the parasite is present in the Danube floodplain forests permanent focus for almost 30 years. Here we provide data on 11-year survey of F. magna acquired from 137 red deer (Cervus elaphus) hunted in the southwestern hunting grounds (districts Komárno and Dunajská Streda). Almost 47 % of all examined deer, including males, females and fawns, were infected with F. magna. During the studied period, the prevalence ranged between 33.3 % (2009) and 63.6 % (2007). Prevalence of fascioloidosis varied between sexes and age categories; while the lowest overall prevalence was detected in females (33.3 %), higher values were documented for red deer males (50.6 %) and fawns (43.3 %). A presence of giant liver fluke in studied regions of southwestern Slovakia deserves future attention and ongoing monitoring due to a possible threat of F. magna infection of domestic ruminants in overlapping regions.
