Wild Rabbits as Reservoir Hosts of the Common Liver Fluke, Fasciola hepatica, in Southern Texas

Histopathological findings of Fasciola hepatica infection in non-native European hare (Lepus europaeus) in Southern Chile

“…In comparison to reports from rabbits, there are similar prevalence recorded from Central Chile; 2.9 to 6.8% (COURTIN et al, 1975(COURTIN et al, , 1979ALCAÍNO et al, 1988;APT et al, 1993) and North America; 4.2% (OLSEN, 1948). In spite of the above, there are reports with higher prevalence in hares from France and Netherlands (12.7% to 39.2%) (BAILENGER et al, 1965;RONDELAUD et al, 2001;WALKER et al, 2011) and North America (18.1%) (OLSEN, 1948), and similarly for rabbits from France (25 to 42%) (MÉNARD et al, 2000;RONDELAUD et al, 2001). The parasitic load recorded in the present study (n= 6) was comparable to previous surveys from North America; 1-7 flukes (OLSEN, 1948) and Europe; 1-8 flukes per animal (SHIMALOV & SHIMALOV, 2000;RONDELAUD et al, 2001;SHIMALOV, 2001;WALKER et al, 2011).…”

“…Nevertheless, Walker et al (2011) and Cuervo et al (2015) recorded highest parasitic loads with 35 and 22 flukes from 1 hare, respectively. In the case of rabbits, a similar situation has been reported from Chile; 1-17 flukes (COURTIN et al, 1975(COURTIN et al, , 1979ALCAÍNO et al, 1988;APT et al, 1993), North America; 3 flukes (OLSEN, 1948) and Europe; 1-6 flukes per animal (CZAPLIŃSKA et al, 1965;RONDELAUD et al, 2001). There is a clear need of additional research about the prevalence, infection intensity and additional wild hosts for this fluke in South America, considering the few records are mainly from rabbits.…”

“…The coprological studies of uncontrolled environments, as occur with samples from wild species, can be biased due to a pseudoparasitism caused by accidental ingestion of fasciolid eggs from pastures (PINTO et al, 2014). In comparison to reports from rabbits, there are similar prevalence recorded from Central Chile; 2.9 to 6.8% (COURTIN et al, 1975(COURTIN et al, , 1979ALCAÍNO et al, 1988;APT et al, 1993) and North America; 4.2% (OLSEN, 1948).

Inventory of wild rodents and lagomorphs as natural hosts ofFasciola hepaticaon a farm located in a humid area in Loire Atlantique (France)

“…cuniculus infection has been reported for a long time (Olsen, 1948) and has been observed in several different countries: in France (Bailenger et al, 1965;Hubard, 1985;Biadi & Le Gall, 1993), in England, USA and Australia (Bailenger et al, 1965), as well as in Rumania (Nesterov et al, 1973), in Czechoslovakia, in Italy and in Chile (Rubilar et al, 1987). The average infection rate measured in our study was in accordance with those reported by the various authors.…”
