Amylase of the snail Australorbis glabratus (Mollusca; Planorbidae)

Comparative Biochemistry and Physiology, 1965
Abstract 1. 1. The amylase of the snail Australorbis glabratus was studied. 2. 2. The enzyme is found throughout the entire digestive tract of the snail as well as in the hemolymph and columellar muscle. 3. 3. The optimum pH of digestive gland amylase is 6 sp5. 4. 4.

Anesthetization of Planorbidae (Mollusca): methodology and pharmacology

Experientia, 1984
A slow drip application of sodium pentobarbital was used to anesthetizeHelisoma duryi for surgery. The use of a 0.01 M Trizma buffer in the anesthetic medium expedites recovery and appeared to reduce swelling of the pedal sinus. These observations are attributed to the restriction of ΔpH favoring the entry of anesthetic into tissues and reducing ...

Estivation of Biomphalaria Glabrata (Basommatophora: Planorbidae)

American Journal of Tropical Medicine and Hygiene, 1967
Summary Diapause and estivation were studied in an albino strain of Biomphalaria glabrata. A group of small lamellate B. glabrata showed a persistent tendency, for an average duration of 29 days, to climb out of the water. These snails subsequently produced 36% lamellate offspring, 64% of which showed a spontaneous tendency to climb out of the water ...

Determination of some water-soluble vitamin levels in Planorbidae

Experimental Parasitology, 1966
Some water-soluble vitamin levels were determined in total snail and in digestive gland extracts of Biomphalaria glabrata. Vitamin B12, folic acid, and pyridoxin levels were higher in digestive gland extract than in total snail extract. Conversely, the levels of choline, nicotinic acid, biotin and para-aminobenzoic acid were higher in total snail ...

Bulinus senegalensis (Mollusca: Planorbidae) in northern Nigeria

Annals of Tropical Medicine & Parasitology, 1983
Surveys in the South Chad Irrigation Project Area have revealed the presence of substantial populations of the important potential snail host for Schistosoma haematobium, Bulinus senegalensis. This is the first confirmed record of this species outside the Senegambian region and the habitats in which it occurs differ from those previously reported.

Distribution and Ecology of Lymnaeidae/Planorbidae Snails in India

2021
Lymnaeidae/planorbidae snails are the intermediate hosts of Fasciola hepatica and Fasciola gigantica. Distribution of these vector snails explains the infection of fasciolosis as per geography and climatic condition of place. It also plays a vital role in the pattern of fasciolosis transmission.

Uptake and assimilation of amino acids by Biomphalaria glabrata (Gastropoda: Planorbidae)

Comparative Biochemistry and Physiology Part A: Physiology, 1972
Abstract 1. 1. Biomphalaria glabrata were incubated in aquarium water containing tritiated amino acids. Specific activities of acid-soluble and acid-insoluble fractions of hemolymph and of tissue were measured from groups of snails maintained for various periods of up to 104 hr post-incubation. 2. 2.

Experimental taxonomy of Bulinus (gastropoda: planorbidae)

Journal of Chromatography A, 1979
The problems encountered in the identification of African freshwater snails of medical importance have resulted in a search for new and more standardized characteristics. The methods described for the horizontal starch gel electrophoresis of single individuals of Bulinus make it possible to score the phenotype of ten different enzymes in the individual.

Karyotype delineation in Isidora truncata (Gastropoda: Planorbidae).

Parassitologia, 1985
Metaphase chromosomes of a single Sardinian population of Isidora truncata were examined in an attempt to provide a picture of a standard karyotype to which Sardinian populations could be referred. Several new foci were identified and mapped.
