Hexamitiasis in tortoises

Abstract

Hexamitiasis was diagnosed in nine chelonians of eight species. The causative organism was identified as Hexamita parva (Alexeieff, 1912). the disease appeared to affect the organs which have an open connection with the intestinal tract.

The kidneys were affected especially. Hexamites could be recognized in collecting ducts and in tubules showing acute and subacute lesions and inflammatory reactions. Parasites were generally absent in tubules revealing signs of regeneration. In the liver, the bile ducts were found to be invaded. Hexamitiasis is a slowly progressing disease causing no specific symptoms.
