PCR diagnosis of Fasciola hepatica in field-collected Lymnaea columella and Lymnaea viatrix snails [PDF]
Veterinary Parasitology, 2006 Fasciolosis, caused by the trematode Fasciola hepatica, is a zoonosis of economic importance in livestock that is emerging as a chronic disease in humans. The intermediate hosts are lymnaeid snails, in which diagnosis of infection is traditionally based on cercarial shedding, tissue sectioning and crushing.

Lymnaea (Pseudosuccinea) columella Say 1817, described from specimens probably obtained in the vicinity of Philadelphia1, is widely distributed in still and slow-flowing waters in the eastern United States of America, Mexico, Central America, Cuba and the northern and central regions of South America1,2.

Experimental Parasitology, 2006
The snails Lymnaea columella and Lymnaea cousini have both been reported as intermediate hosts of Fasciola hepatica in Colombia. The effect of the exposure to the parasite on survival, fecundity and size of these snails was evaluated by means of experimental infections and the life history traits of control and exposed groups were compared.

Egg Production in Lymnaea Columella
The American Naturalist, 1946Egg production and clutch production in Lymnaea columella were found to be directly related. The correlation, on the basis of the daily records, was + .87; on the basis of 10-day periods, it was + .93. A second factor, the length of the laying period, was also found to be to a small, but significant extent related to egg production. Longevity was found

Influence of shell size ofLymnaea columellaon infectivity and development ofFasciola hepatica
Journal of Helminthology, 2008AbstractExperimental infections ofLymnaea columellawithFasciola hepaticawere carried out to determine the influence of shell size on the infection rate and on the outcome of rediae and cercariae. Snails were divided into seven groups according to shell size: 2–4 mm, 5–6 mm, 7–8 mm, 9–10 mm, 11–12 mm, 13–14 mm and 15 mm or more.

An established population of the eastern North American freshwater snail Lymnaea (Pseudosuccinea) columella Say is reported from Middle Creek and Centennial Park, Sydney. This species is an important intermediate host of the liver fluke (Fasciola hepatica Linné) and its introduction and spread in New Zealand has resulted in an increase in the liver ...

The response of the freshwater gasteropods Lymnaea tomentosa and L. columella to desiccation
Journal of Zoology, 1977At a constant temperature and humidity there was a linear relationship between the log of survival time and the log of shell length in Lymnaea tomentosa and L. columella. Reasons are suggested for this relationship. There was no significant species difference in ability to resist desiccation, provided specimens of either species were of similar shell ...

SUMMARY Field surveys were carried out in the Lismore and Casino area for the presence of fresh water snails potentially responsible for the transmission of trematodes in ruminants. Although the North American snail, Lymnaea columella has previously only been reported from metropolitan areas, large populations of the snail were found east of Lismore ...

Radiolabeled metacercariae of Fasciola hepatica were obtained in vivo by incubating infected Lymnaea columella snails with 20 muCi radioselenomethione (75Se-M) per snail in 5 ml of water for 5 h, or in vitro by incubating a batch of unlabeled F. hepatica metacercariae with 75Se-M for 24 h.
