Detection of antigen in the coelomocytes of the earthworm, Eisenia foetida (Annelida)

Immunology Letters, 1991
Earthworms, Eisenia foetida, are able to respond to antigenic stimulation by the formation of the antigen-binding molecules by coelomocytes--the effector cells of annelids' defence reactions. The ability to react with gold-labelled antigen was detected in agranular coelomocytes by electron microscopy.

Mitogenicity of the earthworm's (eisenia foetida) insulin-like proteins

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1993
1. Biologically active glycolipoprotein complex (G-90), isolated from whole earthworm tissue extract (Eisenia foetida), was separated into seven fractions by gel-filtration. 2. It has been shown by radioimmunoassay that each of the fractions, except the lightest one, is cross-reactive with porcine anti-insulin antibodies.

Ecotoxicological effects of microplastics and cadmium on the earthworm Eisenia foetida

Journal of Hazardous Materials, 2020
As microplastics (MPs) have become ubiquitous in both aquatic and terrestrial environments, there has been a growing concern about these new anthropogenic stressors. However, comparatively little is known about the negative effects of MPs, co-contamination of MPs and heavy metals on terrestrial organisms.

Characteristics of cholinesterase of the earthworm Eisenia foetida

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1978
Abstract 1. Except for pH optimum, reactivation and “aging”, the results indicate that the ChE of Eisenia foetida is distinct from acetylcholinesterase and butyrylcholinesterase. 2. Propionylcholine was found to be a better substrate than acetylcholine, while butyrylcholine, benzoylcholine and acetyl-beta-methylcholine were found to be poor ...

Identification of a coelomic mitogenic factor in Eisenia foetida earthworm

Immunology Letters, 1999
Coelomic fluid of earthworms Eisenia foetida (Oligochaeta, Annelida) exerts a mitogenic activity on murine splenocytes. Total coelomic fluid was subjected to size-exclusion chromatography and a semi-purified mitogenic fraction (fraction 5) was isolated and further characterized. Both coelomic fluid and the semi-purified fraction 5 block concanavalin A (

Hyperacute graft rejection inEisenia foetida typica andEisenia foetida unicolor

Experientia, 1975
Das Phanomen der hyperakuten Transplantat-Abstossung (innerhalb von 24 h) wurde bei Invertebraten untersucht. Diese rasche Abstossungsreaktion wird signifikant haufiger bei Allo- oder Xenoals bei Autotransplantationen beobachtet. Dies spricht fur das Vorliegen einer Inkompatibilitatsreaktion.

Fibrinolytic and anticoagulative activities from the earthworm Eisenia foetida

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1998
Biologically active glycolipoprotein complex (G-90) isolated from whole earthworm tissue extract shows anticoagulative and fibrinolytic activities. We isolated two tyrosine like serine peptidases with molecular masses of 34 kDa (P I) and 23 kDa (P II), respectively. P I peptidase is autocatalytically degraded to P II.

Cellular expression of the cytolytic factor in earthworms Eisenia foetida

Immunology Letters, 1998
Coelomic fluid of earthworms contains a 42 kDa protein designated CCF-1 (coelomic cytolytic factor 1), which accounts for approximately 40% of cytolytic activity of the entire coelomic fluid. CCF-1 was documented to be present on cells of the mesenchymal lining of the coelomic cavity as well as on free coelomocytes.

Autofluorescence as a tool to study mucus secretion in Eisenia foetida

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2008
Autofluorescence in living cells is due to the presence of endogenous substances that emit fluorescence upon excitation by incidental light. A type of fluorescence, bioluminescence, has been suggested to be linked to mucus secretion in earthworms; however, the origin and the physiological function of this fluorescence are not clear.

The Role of the Earthworm, Eisenia foetida, in the Transmission of Stephanurus dentatus

The Journal of Parasitology, 1955
unbroken skin. Following entry into the body of the pig, the majority of the larvae reaches the liver where they undergo a long period of development. This culminates in escape of the worms into the peritoneal cavity and their migration to the perirenal area.
