infected by Entamoeba invadense, Onl
J Vet Res., 18(11): 851-858, 2014. Entamoeba invadense may potentially infect all
reptile species and cause invasive disease similar to Entamoeba histolytica infection in humans. There are no reports describing hematological changes caused by Entamoeba invadense in green
iguanas. We describe hematological changes in a naturally E. invadense- infected green iguana. Direct smear of stools showed cysts measuring 20
micrometers in average with four vesicular nuclei morphologically compatible with E. invadens. Packed cell volume was 0.28 (L/L)
and below reference values for green iguanas. Red blood cell count and hemoglobin concentration was decreased and the
white blood cell count showed a moderate response to heterophilic
population stimuli. The intestinal infestation caused by E. invadens with uncompensated anemia and heterophilic leukocytosis with a left shift resulted in
weakness and lethargy which could have predisposed the reptile to non-healing
skin disorders
Key words: Entamoeba invadense,
hematological changes, iguana.
