“…The same effect has been observed in the kidney of bivalves under heavy metal stress (Sulina, 1986(Sulina, , 1989Hemelraad et al, 1990 andRegoli et al, 1992). Also, non metal organic pollutants caused an increase in the number of concretions in the kidneys of the marine prosobranch Littorina littorea and in the freshwater snail Planorbarius corneus (Klobučar et al, 2001). Degeneration of some nephrocytes and hyalinization of fibrous connective tissue were observed in the present study.…”

“…Light microscopic analysis in the present study of the kidney of E. vermiculata showed similarity to some extent to that described for other molluscs as Agriolimax reticulates (Runham and Hunter, 1971); Helix pomatia (Newell and Skelding, 1973); Littorina littrea and Planorbarius corneus (Klobučar et al, 2001). Molluscan kidney consists of a tubule enclosing a luminal cavity derived from the coelom.…”

“…Molluscan kidney consists of a tubule enclosing a luminal cavity derived from the coelom. The nephrocytes lining the luminal surface of the tubule are involved in the secretion of waste and the resorption of metabolites from the urinary fluid (Simkiss andMason, 1983 andKlobučar et al, 2001). The important feature characterizing molluscan kidney is their ability to produce and excrete solids in the urine in the form of concretions (Doyle et al, 1978 andMoya, 1989).…”

Histopathological Changes Induced by Metaldehyde in Eobania vermiculata (Müller 1774)

Metaldehyde is a specific molluscicide for terrestrial snails and slugs. Histopathological changes induced by metaldehyde in the terrestrial snail E. vermiculata were investigated by light microscopy in order to study its cellular toxicity. Alterations in digestive gland included cellular infiltration, destruction of intertubular connective tissue, and extensive vacuolation in the cytoplasm of digestive cells. Degeneration and necrosis in the lining epithelium of the digestive tubules were also noticed. Irregular thickening in the outer covering muscular layer, thinning of basal layer, atrophy and degeneration of mucous cells were the most observed changes in dart gland. The histological alterations in the kidney were degeneration of nephrocytes, and an increase in the number and size of concretions in nephrocytes. Metaldehyde showed cytotoxic effects in all tested organs, that in turn leads to failure of the digestive, reproductive and excretory systems.

“…It was suggested that the concretions could be a means of heavy metal detoxification, the metals being added by accretion onto the external layers of the concretion. Experimental exposure of the freshwater snail Planorbius corneus to the pesticide pentachlorophenol induced an increased production and release of these concretions (Klobucar et al 2001). It seems that the stress caused by pollution such as trace metals causes the increase in kidney concretions.…”

How healthy are cultivated scallops (Argopecten purpuratus) from Chile?: A histopathological survey

Scallop (Argopecten purpuratus) cultivation is an important economic activity in the central-northern region of Chile, and diseases are a permanent concern for farmers and fishing authorities. A one year-long survey was undertaken to find out what parasites and putative pathogens are present in cultivated scallops from three locations: Caldera, Guanaqueros and Tongoy. Ninety adult scallops were sampled from each location, on each season of the year. The soft parts were fixed in Davidson´s fluid, and processed routinely for histology. The prevalence of infection for each parasite and pathologic condition were assessed. Larvae were sampled from three hatcheries and fixed for transmission electron microscopy. The same was done with digestive gland and gill tissues from the first 10 adults of each group sampled for histology. The same parasites and pathologic conditions were found in scallops from the three locations studied: inclusions of rickettsial-like organisms (RLOs) in epithelial digestive gland tubule cells of adults, and in the velar rim of one larva, haemocyte infiltration in gills and digestive gland, two types of granulomas of unknown aetiology in visceral and mantle connective tissues, mineral concretions in kidney, and the protozoan Trichodina sp., a ciliate ectoparasite, on the gills. However, the prevalences of all conditions varied greatly between the three sites and/or seasons. Based on the absence of significant mortalities among cultured scallops at the three sites during the reported survey year, it is concluded that the surveyed scallops were healthy, and that the pathological conditions reported here are generally benign.

“…Therefore, studies on laboratory cultures of candidate species like P. corneus could provide data for breeding and maintenance conditions. P. corneus and other freshwater snails have been used for decades in ecotoxicological research but mainly on specimens collected shortly prior to the experiments without laboratory culturing (Klobučar et al, 1997(Klobučar et al, , 2001Lajtner et al, 1996Lajtner et al, , 2003Otludil et al, 2004;Pavlica et al, 2000;Špoljar et al, 2005). The aim of this paper is to present the results of analyses on the reproduction and growth of P. corneus over the course of several years of continuous rearing in the laboratory, which was conducted in order to use them as a test organism for partial life-cycle and full life-cycle toxicity testing (Mazuran et al, 1999).…”

This study presents the results of observation on growth and reproduction of Planorbarius corneus (Linnaeus, 1758) (Gastropoda, Pulmonata) over the course of several years of continuous rearing in the laboratory in order to use them as test organisms for toxicity testing of chemicals. Some growth and reproduction features (shell diameter increase, fecundity, hatching time and rate, age at first reproduction, juvenile survival), which could provide more information for culturing P. corneus in the laboratory, are presented. The quantitative results of growth and reproduction in laboratory conditions were obtained: heterogenous growth varied between 0.1 mm and 5.3 mm in individual snails, production of 0.6 egg masses per snail/day and 11 eggs per snail/day. A statistically significant negative correlation between initial snail size and growth was noticed. In the second part of the experiment, the reproductive output of 4 isolated snails was compared to that of permanently grouped snails. As a result, 2-fold decreased growth and 4-fold decreased reproductive output in the progeny of isolated animals was noticed.
