ERYTHROCYTE PROFILES OF RANA DALMATINA AND PELOPHYLAX RIDIBUNDUS (AMPHIBIA: RANIDAE)

The research on the erythrocyte profile was conducted on a total of twenty-eight frog individuals, out of which fourteen were Pelophylax ridibundus and also fourteen were Rana dalmatina. The aim of this study was to determine the erythrocyte parameters in the two frog species mentioned, in order to compare the obtained results. The individuals used in the study were captured in the area of Mrkonjić Grad municipality near Lake Balkana. After capture, all individuals were transported to laboratory conditions where they underwent a 15-day adaptation period. Following the adaptation period, blood samples were collected, and erythrocyte parameters were determined, including the number of erythrocytes, hemoglobin concentration, hematocrit and MCV, MCH and MCHC parameters. Based on the obtained results, the study showed that the Pelophylax ridibundus species had significantly higher values of erythrocyte count, hemoglobin concentration and MCHC compared to the values obtained in the Rana dalmatina.
