Ascaris suum: A Scanning Electron Microscope Study

The Journal of Parasitology, 1973
The head, cuticle, and caudal region of the adult worm were examined with the scanning electron microscope. The inner and outer ring of papillae were easily visible as well as the amphids of each subventral lip. Each lip has 2 dentigerous ridges formed by 2 rows of conoidal to rectangular denticles.

Poly(ADP-Ribosylation) inAscaris suum

Hoppe-Seyler´s Zeitschrift für physiologische Chemie, 1984
Poly(ADP-ribosylation) was demonstrated in the intestinal parasite Ascaris suum, especially in the reproductive tissues. The activity of the ADP-ribosyltransferase was found to depend on divalent cations and to be stimulated by deoxyribonuclease I about 5-fold. The reaction rate was optimal at a temperature of 30 degrees C and at pH about 8.4.

Ascaris suum: Homocytotropic antibody responses in mice

Experimental Parasitology, 1976
Abstract Homocytotropic antibodies in the sera of CD-1 and DBA/1 mice infected with larval A. suum were titered by PCA reactions. IgG 1 and reaginic antibody responses were similar in both strains of mice. With a dose of 8000 to 10,000 embryonated eggs, reaginic antibody was detected during the second week and IgG 1 antibody during the third week

Origin of intestinal disaccharidases of Ascaris suum

Experimental Parasitology, 1974
Disaccharidases from the gut of Ascaris suum were investigated to determine whether they were synthesized by the worm or whether they were host enzymes adsorbed to the worms' intestinal cells. Alpha-d-glucoside glucohydrolase (maltase) (EC 3.2.1.20), Beta-d-fructofuranoside fructohydrolase (invertase) (EC 3.2.1.26) and 1-glucohydrolase (trehalase) (EC ...

Ascaris suum: Human lymphocyte mitogenic factor content

Experimental Parasitology, 1987
Ascaris suum extract was found to contain a mitogenic factor which stimulates human lymphocytes. The extract (100 micrograms protein/ml) induced an increase in [3H]thymidine incorporation into human lymphocytes at a level similar to that obtained with pokeweed mitogen (11 micrograms/ml).

Tubulin characterization during embryogenesis of Ascaris suum

Developmental Biology, 1980
Tubulin in cytosolic fractions of Ascaris suum embryos was characterized on the basis of its specific colchicine binding and known properties of the tubulin-colchicine complex. Cytosolic fractions of early (eight-cell) and late (gastrula) embryos maintained at 37°C exhibited significant colchicine binding reaching pseudosaturation at 6 hr.

Ascaris suum: Role of ecdysteroids in molting

Experimental Parasitology, 1985
Three studies were conducted to examine the function of ecdysteroids in the development of parasitic nematodes. Ecdysone and 20-hydroxyecdysone were extracted, separated chromatographically, and measured in the reproductive tracts of adult female Ascaris suum.

Phosphoenolpyruvate carboxykinase activity in Ascaris suum muscle

Comparative Biochemistry and Physiology, 1969
Abstract 1. 1. Phosphoenolpyruvate (PEP) carboxykinase activity was measured for four subcellular fractions of Ascaris suum muslce. Mos activity was associated with the soluble fraction. 2. 2. The reaction had a pH optimum of about 7·2. 3. 3. Mn ++ was a more effective promoter of the reaction than Mg ++ . 4. 4.
