El objetivo principal de este trabajo fue evaluar el efecto de la lombriz roja californiana sobre el crecimiento de microorganismos en suelos contaminados con mercurio en el municipio de Segovia, Antioquia.

Full Text Available The efficiency of composting processes with and without the addition of Californian red worms Eisenia foetida was evaluated, using manure of dairy cows to generate organic fertilizer. A linear model was used in the statistical analysis, with four replicates that included as fixed effects, the composting systems and time.

K and Na concentrations were higher in the compost than in the vermicompost. The mean of pH presented differences in the two systems of decomposition. The germination index, using lettuce seeds Lactuca sativa L.


Grandes Lagos in vitro, of the decomposition products increased in week 25, indicating the degree of maturity reached. Full Text Available The effects of malathion and chlorpyrifos on immune responses of Eisenia sp.

In plastic containers with natural soils as substrate, mature sexually earthworms were exposed to malathion mg kg-1of soil and chlorpyrifos mg kg-1of soil during 7 and 21 days. After exposure periods, cellular viability, total number of coelomocytes NTC, percentage of phagocytic cells PCF, lysozyme activity and hemolytic percentage were determined. Malathion and chlorpyrifos exposures caused a significant decrease in NTC, lysozyme and hemolytic activities, but these variables were not affected by time of exposure.

PCF declined in earthworms exposed to both pesticides; this decline was dependent of the time-exposure. The results suggest an immunotoxic action of both agrochemicals on humoral and cellular immune responses of Eisenia sp. The immune responses mediated by the coelocmocytes of Eisenia sp. The organisms were exposed to concentrations of 0; 2. Cd levels increased in the exposed organisms proportionally to the concentrations and duration of exposure; this metal was mostly accumulated to the MP region.

TBARS concentrations increased in doses-days relationship, showed the highest levels in MA; this increment is probably associated to the Cd-bioacumulation that can affect the mechanisms of defenses against reactive oxygen species.

MT concentrations in exposed organisms suggest their relevance as effective response of molecular defense against Cd toxicity. These corporal biochemical responses associated to Cd-uptake form part of the molecular defense system that avoids interferences on the reproductive tissue clitellum, allowing to accumulate the highest quantity of Cd in the MP region. Eisenia andrei has a differential capacity along its body to modulate adjustments of molecular responses, which could allow the tolerance and effectiveness of survival in Cd-polluted soils.

However, several copper Cu mining operations are located in the basin. The objective of the study was to determine Cu toxicity for the earthworm Eisenia fetida Savigny in the agricultural soils of the basin. We determined the production of cocoons and juveniles of earthworms in the studied soils. In contrast, pH and texture did not affect this response. Cocoon production decreased in the soils with Cu concentrations below mg kg-1 when OM concentrations were below 3.

In contrast, cocoon production did not vary when OM concentrations were above 3. The same effect of OM was observed on juvenile production. In this case, the threshold for OM concentration was 2.


It was concluded that it is important to consider OM concentrations in order to predict the biological response of earthworms in these soils. Full Text Available The possible effect of the drying temperature of cultivi earthworm, Eisenia andrei, biomass on the amino acid profile of the resulting flour was evaluated. A tray dryer with air recirculation was used as a drying technique. Although, under the experimental conditions of the proposed approach, the results in terms of lombrkz values were expected and satisfactory, they were not convenient in terms of microbiological quality.

The results allow to infer that the use of low temperature drying is not a recommended approach to obtain earthworm meal, unless experimental conditions also ensure the microbiological quality without compromising the cost-benefit of the proposed drying process.

El espacio resulta fundamental en el teatro y Rojas utiliza con gran habilidad tanto los espacios abiertos como los cerrados. Abstract Two new megadrile earthworms from the steppes, the first species wholly from Outer Mongolia, are ascribed to the partially parthenogenetic Eisenia nordenskioldi Eisen, species-complex.

Taxonomic justification of sympatric Eisenia nordenskioldi mongol and Eisenia nordenskioldi onon ssp. Similar species described from Northeast China [formerly Manchuria] and North Korea are briefly considered, albeit they are intermittently held in synonymy of cosmopolitan Aporrectodea rosea Savigny, along with many other taxa including some exotic lumbricids initially found in India.

Japanese and North American lumbricids are also mentioned. Full Text Available It has been determined the bioaccumulation of Cu, Fe, Zn and Se, in the tissue of earthworms to evaluate the possibility of use as a nutritional supplement. Was analyzed a vermicompost enriched substrate control and three doses of each element. We studied the effect on growth, mortality and tissue concentrations.

Significant differences were found for copper control, However, tissue concentrations for all groups are high compared to some foods from the diet is an alternative to replace and compensate for the deficiency of these trace elements. This conflict lead to a revolution that ended with the President’s suicide, when he was refuged at the Argentinian Embassy in September President Balmaceda conducted an authoritarian government during several months.

Rojas worked gratuitously and became prominent, being named Chief Surgeon of the Chilean Army. After the triumph of the revolution against President Balmaceda, Dr Rojas was discharged, and died in Las propiedades evaluadas fueron: Feeding activity of the earthworm Eisenia andrei in artificial soil.

Quantitative information on the feeding activity of earthworms is scarce but this information is valuable in many eco toxico logical studies. In this study, the feeding activity of the compost worm Eisenia andrei is examined in artificial soil OECD mediumwith and without a high-quality food. Evidence for proteins involved in prophenoloxidase cascade Eisenia fetida earthworms.


EE – Microbiology, Virology Impact factor: EC – Immunology Impact factor: Relationship between hemolytic molecules in Eisenia fetida earthworms. CD – Macromolecular Chemistry Impact factor: Microbial environment affects innate immunity in two closely related earthworm species Eisenia andrei and Eisenia fetida. Full Text Available 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.

Therefore, the influence of environment-specific microbiota on the immune response of both species was followed.

Firstly, a reliable method to discern between E. Secondly, to analyze the immunological profile in both earthworm species, the activity and expression of lysozyme, pattern recognition protein CCF, and antimicrobial proteins with hemolytic function, fetidin and lysenins, have been assessed. It can be hypothesized that E.

Avoidance behaviour testing of Eisenia andrei in biodegradable plastic environment. The purpose of the testing is to determine the avoidance behaviour of earthworm in this case Eisenia andrei was used which can be used as an organism for the composting and occur naturally in soil environment. The methodology was modified according to the needs of the avoidance behaviour testing of earthworms in biodegradable plastic environment.

It is a biodegradable thermoplastic material Mater-Bi, which is produced from corn starch. Californian earthworm Eisenia andrei was chosen as a test organism. The two-chamber test was used in testing. It was recorded both a positive result, avoidance reaction, as well as a negative result, non-avoidance reaction and also there was a case, where individuals prefer both substrates equally.

Organisms showed no escape reaction and were fairly evenly distributed in both halves of the test vessel, it can be assessed that organisms prefer both substrates equally. In testing, the mortality was zero, none of the individuals died, at the conclusion of the test there were not found any dead individuals. At 50 and mg phenanthrene kg -1 E.

Only small amounts of PAHs were detected in the earthworms.
