Decreased erytrocyte osmotic fragility during canine leptospirosis

Diminuição da fragilidade osmótica eritrocitária na leptospirose canina

Abstracts

Erythrocyte osmotic fragility (EOF) was carried out in nineteen dogs naturally infected by Leptospira interrogans serovar icterohaemorrhagiae/copenhagi. A decreased EOF was observed, suggesting a modification of erythrocyte components secondary to disturbances that occur during canine leptospirosis, such as renal damage and hepatic disease.

A fragilidade osmótica eritrocitária foi estudada em dezenove cães infectados naturalmente pela Leptospira interrogans serovar icterohaemorrhagiae/copenhagi. Observou-se uma redução da fragilidade osmótica eritrocitária, sem a presença de anemia, possivelmente relacionada aos distúrbios hepato-renais que ocorrem nesta patologia.
