Nucleoli of the overwintering strobilal cells of scotch pine

Protoplasma, 1980
Monthly collections from October to April revealed seasonal alterations in the structure of the nucleoli of the microsporangiate strobili of the Scotch pine (Pinus sylvestris L.). By classifying the nucleoli in five types, two of them with subtypes, it was possible to list the amount and the sequence of the changes.

Cnidarian–algal partnerships structure bacterial communities during strobilation in Cassiopea xamachana

ISME Communications
Cnidarian–algal (Symbiodiniaceae) symbioses rely on complex interactions among the cnidarian host, algal symbionts and associated bacterial communities.

Hymenolepis diminuta: Immunogenicity of the strobilate worm

Zeitschrift f�r Parasitenkunde Parasitology Research, 1983
Mice were immunized against challenge with Hymenolepis diminuta by feeding cysticercoids or by surgically implanting into the duodenum strobilate worms of different ages. Young worms stimulate stronger immunity than older ones, although the latter presents the host with a greater amount of strobilar tissue per unit time.

SEM Studies of Strobilating Aurelia

1976
Strobilation in Texas Aurelia provides a rapid, controlled developmental model for the study of morphogenetic changes in biological organisms. The Texas Aurelia polyps (scyphistomae) are induced to strobilate using thyroxine which initiates segmentation in the organisms in 2–3 days. The segments metamorphose into ephyrae in 3 days.

Juvenile Strobilate Tapeworm from the Human Spinal Cord

The American Journal of Tropical Medicine and Hygiene, 1972
Abstract A juvenile strobilate tapeworm was found in the spinal cord of a young man from Thailand who had suffered from paraplegia for several months. The recovered worm was 76 mm long and its scolex had four muscular suckers and a rostellum with hooks.

Transient Transduction of the Strobilated Forms of Echinococcus granulosus.

Journal of visualized experiments : JoVE, 2022
Cystic echinococcosis or hydatid disease is one of the most important zoonotic parasitic diseases caused by Echinococcus granulosus, a small tapeworm harbored in the intestine of canines. There is an urgent need for applied genetic research to understand the mechanisms of pathogenesis and disease control and prevention.

Further analysis of the factors controlling strobilization, differentiation, and maturation of Echinococcus granulosus in vitro

Experimental Parasitology, 1967
Abstract The conditions under which protoscoleces of Echinococcus granulosus will develop in vitro in a strobilar direction (in contrast to a cystic direction) were further investigated and defined. A diphasic medium of coagulated bovine serum and a liquid phase of Medium 858 + 20% hydatid fluid with a gas phase of 10–20% O 2 + 5% CO 2 in N 2 ...

Metabolism of 131I in relation to strobilation of Aurelia aurita L. (Scyphozoa)

Journal of Experimental Marine Biology and Ecology, 1974
Abstract The 131 I isotope of iodine has been used to follow the uptake and metabolism of iodine during the process of strobilation in pre-conditioned polyps of Aurelia aurita L. Strobilating polyps accumulated free iodide from the media against a concentration gradient, the segmented portion of the polyps accumulating about three times as much as

Strobilation in the Chesapeake Bay sea nettle Chrysaora quinquecirrha. I. The effects of environmental temperature changes on strobilation and growth

Journal of Experimental Zoology, 1972
AbstractObservation of Chrysaora polyps taken from the Chesapeake Bay and maintained in the laboratory reveals at least four morphological types of animals, chiefly distinguished by the number of tentacles they bear and the manner of strobilation. All of the types strobilate when warmed after sufficient chilling; several waves of strobilations may ...
