current decline in the number and size of galba truncatula and omphiscola glabra populations, intermediate hosts of fasciola hepatica, on the acidic soils of central france.field investigations on the habitats colonized by galba truncatula or omphiscola glabra were carried out on 162 farms of the limousin region, central france, to determine whether there is currently a decline in the number and size of snail populations. seven types of snail habitats were considered here. compared to the numbers of snail populations recorded from 1976 to 1992, the values noted from 2013 to 2016 were significantly lower, with a decline rate of 34% for g. truncatula and 23% for o. g ...201627774956
fasciola hepatica: the developmental patterns of redial generations in naturally infected galba truncatula.a retrospective study on 1,211 snails naturally infected with fasciola hepatica in central france was carried out to determine the numbers of full-grown sporocysts from which infections derived, to specify the developmental patterns of redial generations (normal or abnormal) and to count live and free rediae. in the department of haute vienne (siliceous subsoils), most snails showed single-sporocyst infections, with normal (46.3%) or abnormal (33.9%) development of redial generations. two-sporoc ...200415338285
the definitive and intermediate hosts of fasciola hepatica in the natural watercress beds in central france.field investigations were carried out over a two-year period in 52 natural watercress beds located in the limousin region of central france to list the mammal and bird species that frequented these sites. this enabled detection of the definitive hosts of fasciola hepatica and determination of the prevalence of natural infection in snails. a total of 13 mammal and five bird species were listed in these watercress beds. adult flukes were found in lepus capensis (39.2%), oryctolagus cuniculus (42.0 ...200111411948
larval trematode infections in galba truncatula (gastropoda, lymnaeidae) from the brenne regional natural park, central france.adult galba truncatula ( ≥ 4 mm in shell height) were collected from 135 habitats for 3 years (2012-2014) to identify parasite species via the study of cercariae, and to determine the prevalence of each digenean infection in relation to the type of snail habitat (six types). a total of 323 infected snails and ten digenean species were noted in the bodies of 11,025 g. truncatula after their dissection. snails with calicophoron daubneyi and/or fasciola hepatica were found in 20.7% and 12.5% of the ...201625804319
[epidemiological data on human distomatosis (fasciola hepatica l.) in the limousin region of france. the species of plants eaten and snail hosts].these epidemiological studies concern 187 cases of human fasciolasis which occurred in the region of limousin, france on a period of 24 years. four species of plants have been eaten: nasturtium officinale, roripa silvestris, taraxacum gr. officinale, valerianella olitoria. these plants have been eaten during all months of the year, but with higher numbers in july-august and from november to february. the cases of human fasciolasis almost take place on all years, but their numbers are high in yea ...19807458166

fasciola hepatica: epidemiological surveillance of natural watercress beds in central france.a total of 59 natural watercress beds in the limousin region (central france) was surveyed over a 15-year period (1990-2004) to detect the contamination of watercress by the metacercariae of fasciola hepatica and to determine the presence of larval forms in the two species of lymnaeids which live in these waterholes in june and july. the number of beds contaminated with f. hepatica metacercariae varied over the years, and the burden of the larvae on plants was low: a mean of 2.6-6.3 per bed. the ...200515682341
[epidemiological studies on 121 case of human fascioliasis occurring during 25 years (author's transl)].epidemiological investigations in haute-vienne (france) showed the occurrence of 121 cases of human fascioliasis between 1955 and 1979. 39 cases were counted in limoges and 82 cases in the other districts of haute-vienne with a higher number of cases located in the western districts of low altitude (under 300 m). human cases occurred nearly through all the years, but they were more abundant on years with an important f. hepatica infection of cattle and sheep. the infected plants' ingestion occur ...19827105299
[experimental studies on competition between potamopyrgus jenkinsi against lymnaea (g.) truncatula in vienna and haute-vienne (france) (author's transl)].p. jenkinsi is not an intermediate vector of fasciola hepatica. in lymneae habitats with periodical dessiccation, potamopyrgus can not live long. permanent water is necessary: under these conditions, potamopyrgus competition has a positive effect upon lymnaea ecology.1977907287
[the water-cress pools in connection with cases of human fasciolasis in limousin, france. experimental studies of trematode snails and their biological control (author's transl)].experimental studies on 16 water-cress pools with cases of human fasciolasis in limousin were undertaken. two species of snails, lymnaea glabra and l. truncatula are here trematode hosts. l. glabra alone lives in 5 pools. the introduction of zonitoides nitidus -- predatory snail -- without vegetation modification produces a progressive elimination of lymnaea in 3 years. the author insists on the use of determine the trematode host-aptitude of l. glabra and its limits when the two species -- l. g ...1978754620
changes in human fasciolosis in a temperate area: about some observations over a 28-year period in central france.a retrospective study of 616 patients affected by fasciolosis was carried out to determine the numerical fluctuations of this disease over time, the recruitment of patients, and the modes of infection in a cattle-rearing area under a temperate climate (region of limousin, central france). the annual number of patients showed irregular fluctuations between 1955 and 1987, after which it showed subsequent decreases until 1998. before 1980, 66.3% of the persons under study were living in villages, w ...200011002984
prevalence of paramphistomum daubneyi infection in cattle in central france.investigations at the slaughterhouse of limoges (central france) were performed in 1994-1996 to determine the prevalence of paramphistomum daubneyi infection in cattle. in 1994/1995, higher prevalences of p. daubneyi were recorded in may, october, and january. in 1996, smaller variations were recorded, and prevalence in april and may was higher. the prevalence of p. daubneyi in summer was lower. breed and age of cattle were not significantly associated to p. daubneyi infection, but females were ...200010622604
a field study of natural infections in three freshwater snails with fasciola hepatica and/or paramphistomum daubneyi in central france.natural infections of three freshwater snails with fasciola hepatica and/or paramphistomum daubneyi were studied during two periods in 1996 and 1997 (june-july and september-october) on 18 farms located in the departments of vienne and haute vienne (central france), and known for low prevalences of f. hepatica infections in ruminants. a total of 1573 lymnaea glabra and 1421 l. truncatula 6 mm high or more were collected in the meadows of 13 farms and dissected under laboratory conditions. snails ...200010953217
