A morphological study in the kidney and spleen of gilthead, Sparus aurata, L. caused by sodium dodecyl sulphate.

This paper reports the morphological changes in the kidney and spleen of gilthead (Sparus aurata, L), caused by acute action of the anionic detergent, sodium dodecyl sulphate (SDS). Twenty-five giltheads were exposed to SDS concentrations of 5, 8.5, 10 and 15 mg/l. Morphological changes depending on detergent concentrations and length of exposure were seen. Kidney shows loss of normal structure with tubular and renal corpuscle retraction; spleen shows tendency to damage the reticulae structure and a progressive increase of leucocytes and red cells infiltration.
