Microbial Environment Affects Innate Immunity in Two Closely Related Earthworm Species Eisenia andrei and Eisenia fetida
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...
متن کاملEnumeration of Gut Bacterial Population in Eisenia fetida Exposed to Chlorpyrifos
Earthworms being the most efficient soil organism to improve soil fertility by burrowing deeply into subsoil surfaces and then releasing it out in the form of nutrient enriched cast (Lavelle, 2011). As they are abundant in number and highly productive species, so they are keystone species in the food web of soil environment (Thakuria et al., 2010). Earthworm burrows and drilosphere act as micro...
متن کاملEcotoxicity of Sodium Arsenite on Eisenia Fetida
In this study, we performed ecotoxicity tests of sodium arsenite on soil invertebrate Eisenia fetida. Initially, broad range of sodium arsenite (0.1, 1, 10, 100mg/ml) was tested for mortality of E. fetida after 24 hours in filter paper test. The narrow range doses (0-1mg/ml) were further tested to determine the EC50 and LD50. The EC50 dose of sodium arsenite was considered at which 50% of earth...
متن کاملBioaccumulation of metals in Eisenia fetida after exposure to a metal-loaded bauxsol reagent.
The present study investigated the acute toxic effects of a metal-loaded Bauxsol reagent (MLBR), containing more than 6,450 mg kg(-1) of bound metal, on the earthworm Eisenia fetida. Bauxsol is manufactured by Virotec Global Solutions of Gold Coast, Queensland, Australia. The E. fetida were exposed to 0, 10, 20, 40, 60, and 80% treatments of MLBR plus cow manure for 28 d. Good motility and no m...
متن کاملExposure to 17β-Oestradiol Induces Oxidative Stress in the Non-Oestrogen Receptor Invertebrate Species Eisenia fetida
BACKGROUND The environmental impacts of various substances on all levels of organisms are under investigation. Among these substances, endocrine-disrupting compounds (EDCs) present a threat, although the environmental significance of these compounds remains largely unknown. To shed some light on this field, we assessed the effects of 17β-oestradiol on the growth, reproduction and formation of f...
