Abstract
Canine hepatozoonosis is an endemic tick-borne disease of Thailand, but the clinical data for the disease are rarely reported. The objective of this study was intended to characterize the clinical hematology and biochemistry of admitted canine hepatozoonosis cases of the Chulalongkorn Small Animal Teaching Hospital, Bangkok from January 2001 to December 2003. A total of 342 dogs were examined in this study. Most of the dogs presented with hypocytic hypochromic anemia. Leukocyte and platelet counts were variable and nonspecific in these cases. Additionally, serum biochemistry including blood urea nitrogen, creatinine, liver enzymes, total protein, albumin, and glucose of infected dogs were within normal ranges. This study indicated that hypocytic hypochromic anemia was a consistent hematological value feature of canine hepatozoonosis, but clinical biochemical findings were not consistent in this endemic-hospital population of canine hepatozoonosis.
