Survival of earthworms in the environment depends on their ability to recognize and eliminate potential pathogens. This work is aimed to compare the innate defense mechanisms of two closely related earthworm species, Eisenia andrei and Eisenia fetida, that inhabit substantially different ecological niches. While E. andrei lives in a compost and manure, E. fetida can be found in the litter layer...
POPOVIĆ, M., M. GRDIŠA, T. M. HRŽENJAK: Glycolipoprotein G-90 obtained from the earthworm Eisenia foetida exerts antibacterial activity. Vet. arhiv 75, 119128, 2005. ABSTRACT G-90 is a glycolipoprotein mixture obtained from the tissue homogenate of earthworm Eisenia foetida (Annelida, Lumbricidae) which exhibits pleiotropic biological functions. The antibacterial activity of G-90 was investigat...
Acid rain is still an issue of environmental concerns. This study investigated the impacts of simulated acid rain (SAR) upon earthworm activity from the Latosol (acidic red soil). Laboratory experiment was performed by leaching the soil columns grown with earthworms (Eisenia fetida) at the SAR pH levels ranged from 2.0 to 6.5 over a 34-day period. Results showed that earthworms tended to escape...
A new bioactive proline-rich cyclohexapeptide - diandrine C (6), previously isolated from whole plant of Drymaria diandra (Caryophyllaceae), was synthesized through coupling reactions of tetrapeptide unit Boc-Gly-l-Pro-l-Tyr-l-Trp-OH with dipeptide unit l-Pro-Gly-OMe using N,N-diisopropylcarbodiimide (DIPC) as the coupling agent, followed by cyclization of l...
Soil compaction can occur due to trafficking by heavy equipment and be exacerbated unfavourable conditions such as wet weather. Compaction restrict crop growth increase waterlogging, which the production of greenhouse gas nitrous oxide. Cultivation used alleviate compaction, but this have negative impacts on earthworm abundance carbon dioxide. In study, a field was purposefully compacted using ...
Introduction The earthworm coelomic fluid (ECF) has shown proven antiproliferative effect against breast, liver, gastrointestinal, and brain cancer, but it is least explored in oral cancer. The present in vitro study is an attempt to investigate the antiproliferative activity of ECF on oral cancer cell line squamous cell carcinoma (SCC)-9. Materials and Methods ECF was collected from the spec...
The ethanolic extract of the plant Pistia stratiotes (Araceae) was investigated for activity against Indian earthworms Pheretima posthuma and nematode Ascardi galli. Various concentrations (10, 20, 50 mg/ml) of ethanolic extract were tested, which involved determination of time of paralysis and time of death of the worms. It was compared with Piperazine citrate (15 mg/ml) and Albendazole (20 mg...
soil productivity and plant growth are usually affected by biological activities of earthworms. the objective of this study was a comparative evaluation of earthworm abundances in 20-year-old plantations of alder, oak, maple and cypress with the adjacent natural mixed broad-leaved deciduous forest in the caspian region of iran. in this research one sample plot, each 1 ha; was selected in every ...
Earthworms are nocturnal animals and have negative phototaxis, therefore the presence color of light thought to affect performance this Lumbricus rubellus earthworm. This study aims analyze effect different lights on performance. used acompletely randomized design (RAL), six treatments (red, orange, yellow, green, blue, purple, dark as a control) three replications with variables observed were ...
This paper re-evaluated the use of DNA barcodes in earthworm species identification by re-analyzing sequence data for the mitochondrial cytochrome c oxidase subunit 1 (COI) gene. This analysis unveiled and confirmed taxonomic inconsistencies which significantly affect data interpretation. When considering synonymy and misidentification in published records, our results revealed no shared COI ha...
