corneus" under high temperatures has been studied by Kartavykh & Podkovkin (2002).
The known first intermediate hosts of "Hypoderaeum conoideum" include the freshwater snails "
corneus", "Indoplanorbis exustus", "Lymnaea stagnalis", "Lymnaea limosa", "Radix ovata" and "Radix rubiginosa".
corneus" is the largest European species of ramshorn snail (family Planorbidae), with a shell typically measuring across when fully-grown.
"Schistosoma bovis" infects two hosts, namely ruminants (cattle, goats, sheep, horses, camels and pigs) and freshwater snails ("Bulinus" sp. and "
is a genus of air-breathing freshwater snails, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails, or planorbids, which all have sinistral or left-coiling shells.
corneus, common name the great ramshorn, is a relatively large species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails, or planorbids, which all have sinistral or left-coiling shells.
Most of these snails are of the family Planorbidae, and they include the species "
corneus". There are two different coloured skin forms: black and red; the latter lack the dark skin pigment melanin and consequently have a bright reddish skin, which is the colour of their blood. Interestingly their blood contains red hemoglobin, unlike other snails' blood, which contains greenish hemocyanin.
Referring to invertebrates, "
corneus" is a mollusc involved in one of the many ionic experiments. To begin with, neurones of molluscan pedal ganglia were isolated and transferred to a special chamber with saline solution and regulated temperature. Then, the observation was based on routine voltage clamp technique. Electrical measurements were obtained from the evaluation of neurones response to various substances (argiopines).
When the female gapeworm lays her eggs in the trachea of an infected bird, the eggs are coughed up, swallowed, then defecated. When birds consume the eggs found in the feces of an intermediate host such as earthworms, snails ("
corneus", "Bithynia tentaculata" and others), or slugs, they become infected with the parasite.
The width of the shell can reach up to 10 mm. In the largest specimen there are almost two teleoconch whorls that initially attach very high onto the protoconch, with the result that the larval shell seems to be embedded rather obliquely within the younger whorls. The diameter of the teleoconch increases rapidly, the result being a shell that strongly resembles "
" (but, of course, dextral). The surface of these younger whorls bears flexuous growth lines, and a dense and very fine, somewhat irregular spiral striation, only visible where light reflects on the shell. On the body whorl a distinct peripheral belt is present on which the growth lines are strongly bent backward, indicating a deep sinus in the apertural margin.
Miracidia penetrate into the intermediate host, the freshwater snails of the "Bulinus" spp., (e.g. "B. globosus", "B. forskalii", "B. nyassanus" and "B. truncatus"), except in Spain, Portugal and Marocco, where "
metidjensis" can transmit. Inside the snail, the miracidium sheds its epithelium, and develops into a mother sporocyst. After two weeks the mother begins forming daughter sporocysts. One month -or more with cooler ambient temperatures- after a miracidium has penetrated into the snail, hundreds to thousands of cercariae of the same sex begin to be released through special areas of the sporocyst wall. The cercariae cycle from the top of the water to the bottom in search of a host. They can enter the host epithelium within minutes.
corneus" is distributed from western Europe, through central Europe and into the Caucasus, north into Siberia and south into the Middle East. In western Europe, it has been recorded in Belgium, France and the British Isles (including Britain, Ireland, the Isle of Man, Guernsey and Jersey). It is not found in Spain, but it has been recorded on some Spanish and Portuguese Atlantic islands, including Madeira, the Azores, the Canary Islands. In the Nordic countries, it has been recorded in Denmark, Finland, Sweden and Norway. Its range extends through central Europe (including Austria, Germany, the Netherlands, Luxembourg, Lichtenstein, Switzerland and the Czech Republic) into southern Europe (where it has been recorded in Greece and Italy) and eastern Europe and the Caucasus (including Albania, Armenia, Azerbaijan, Bosnia and Herzegovina, Bulgaria, Croatia, Estonia, Hungary, Latvia, Lithuania, Macedonia, Montenegro, Poland, Romania, Serbia, Slovakia, Slovenia and the Ukraine). The species is also found in western Asia, having been recorded in Kazakhstan, Iran, western regions of Russia, Turkey, Turkmenistan and Uzbekistan.
