Summary The increasing prevalence of yellow‐bellied sliders ( Trachemys scripta scripta ) as pets in the European Union and also its utilization as animal models for experimental purposes makes crucial an accurate classification of their blood cells. The aim of this work was to provide a morphologic classification based on the cytochemical characteristics of the blood cells of 15 yellow‐bellied sliders. Cytochemical stains included benzidine peroxidase, chloroacetate esterase, alpha‐naphthyl butyrate esterase (with and without sodium fluoride), acid phosphatase (with and without tartaric acid), Sudan black B, periodic acid–Schiff and toluidine blue. Nuclear and cellular dimensions were also measured based on quick Romanowsky‐type stained smears. Besides erythrocytes and thrombocytes, five types of white blood cells were identified: heterophils, eosinophils, basophils, lymphocytes and monocytes. The cytochemical patterns of heterophils, eosinophils and basophils were unique compared to those described for other chelonians. This paper provides a useful guideline for clinical settings and further haematological studies of this species.
