Protozoan Parasites of the Cane Toad, Bufo-Marinus, in Australia [PDF]

Australian Journal of Zoology, 1988
A survey of the protozoan parasites of the introduced South American cane toad, Bufo marinus, was conducted between 1983 and 1984 in Queensland. In all, 267 fully grown specimens, 7 juveniles and 115 tadpoles were checked for blood, cloaca, gall bladder and, for the tadpoles only, skin protozoans, and results are compared with records of the toad's ...

Microbodies (peroxisomes) in the toad, Bufo marinus [PDF]

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1970
Microbodies (peroxisomes), a group of cytoplasmic organelles enriched in catalase, are demonstrated in the toad, Bufo marinus, by light and electron microscopy by means of a cytochemical staining procedure that demonstrates the peroxidatic activity of catalase with diaminobenzidine (DAB).

Motor innervation of the toad iris (Bufo marinus) [PDF]

American Journal of Physiology-Legacy Content, 1976
The sphincter pupillae muscle cells in the iris of Bufo marinus contract autonomously in response to bright light, causing a rapid constriction of the pupil. A strong sympathetic beta-adrenergic inhibition of the sphincter pupillae is apparent in this species. The inhibitory fibers can originate in the second, third, or fourth ventral spinal roots. No

Pepsin in the toad Bufo marinus

Comparative Biochemistry and Physiology Part A: Physiology, 1986
The macroscopic localization of pepsinogen in the upper gastrointestinal tract of the anuran Bufo marinus was studied by means of biochemical assay. The pH optimum of the anuran pepsin was determined to be 1.6. The effect of lowered ambient temperature on stored pepsinogen and proteolytic activity was studied. Both parameters were reduced.

Neurohypophysial function in the toad Bufo marinus

General and Comparative Endocrinology, 1967
Abstract A method for ureteral catheterization of the toad without need of surgical incision is described. Changes of ureteral urine flow and osmolality as well as the rate of bladder urine reabsorption were studied before and after the injection of hypertonic salt in the toad Bufo marinus.
