Pseudosuccinea columella , the American ribbed fluke snail, is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae, the pond snails.
This snail is an intermediate host for Fasciola hepatica , the liver fluke, a parasite of livestock, especially sheep. [4]
Pseudosuccinea columella is native to North America. [5] and Europe. [6] The indigenous distribution of Pseudosuccinea columella reaches from New Brunswick and south Manitoba throughout the eastern US to Central and South America. [7]
The exact type locality for this species is unknown, but it is somewhere in the Philadelphia area, US. [8]
This snail has been introduced to Australia [5] and Europe. [6]
The non-indigenous distribution of Pseudosuccinea columella includes:
Europe:
The shell quite closely resembles shells in the genus Succinea , which belongs to a different family.
The shell of Pseudosuccinea columella is horny brown, thin, translucent, fragile and very finely striated. The apex is pointed. The shell has 3.5–4 weakly convex whorls with a shallow suture. The last whorl predominates. The aperture is ovate. The upper palatal margin descends steeply. The columellar margin is reflected only at its upper section; the lower columellar margin sharp and straight. [7]
The width of the shell is 8–13 mm. The height of the shell is 15–20 mm. [7]
The animal is dusky with whitish spots. The eyes are small and black and are located at the inner base of the tentacles. [7]
In North America, Pseudosuccinea columella lives in stagnant waters, at the edges of lakes, ponds, muddy and sluggish streams, among lily pads and reeds on sticks and mud. [7]
In Europe it occurs predominantly in greenhouses, but also sometimes in outdoor habitats (Austria, Hungary). [7] It needs warm water and does not survive Central European winter temperatures. [7] It is also found above the water on floating leaves of aquatic plants; in northern Greece it was found in a spring near a road. [7]
Parasites of Pseudosuccinea columella include:
Fasciola hepatica, also known as the common liver fluke or sheep liver fluke, is a parasitic trematode of the class Trematoda, phylum Platyhelminthes. It infects the livers of various mammals, including humans, and is transmitted by sheep and cattle to humans all over the world. The disease caused by the fluke is called fasciolosis or fascioliasis, which is a type of helminthiasis and has been classified as a neglected tropical disease. Fasciolosis is currently classified as a plant/food-borne trematode infection, often acquired through eating the parasite's metacercariae encysted on plants. F. hepatica, which is distributed worldwide, has been known as an important parasite of sheep and cattle for decades and causes significant economic losses in these livestock species, up to £23 million in the UK alone. Because of its relatively large size and economic importance, it has been the subject of many scientific investigations and may be the best-known of any trematode species. F. hepatica's closest relative is Fasciola gigantica. These two flukes are sister species; they share many morphological features and can mate with each other.
Fasciola, commonly known as the liver fluke, is a genus of parasitic trematodes. There are three species within the genus Fasciola: Fasciola nyanzae,Fasciolahepatica and Fasciolagigantica. Fasciola hepatica and F. gigantica are known to form hybrids. Both F. hepatica and F. gigantica and their hybrids infect the liver tissue of a wide variety of mammals, including humans, in a condition known as fascioliasis. F. hepatica measures up to 30 mm by 15 mm, while F. gigantica measures up to 75 mm by 15 mm. Fasciola nyanzae is thought to exclusively infect the common hippopotamus, Hippopotamus amphibius.
Fasciola gigantica is a parasitic flatworm of the class Trematoda, which causes tropical fascioliasis. It is regarded as one of the most important single platyhelminth infections of ruminants in Asia and Africa. The infection is commonly called fasciolosis.
