Níveis séricos da gama-glutamiltransferase em cães com e sem infecção natural por Leishmania (Leishmania) chagasi / Serum levels of gamma-glutamyl transferase in dogs naturally infected or not by Leishmania (Leishmania) Chagasi

The serum levels of Gamma-GT in dogs naturally infected by Leishmania (Leishmania) chagasi were evaluated. Two groups of animals were used: the first with 41 naturally infect dogs and the second with 14 uninfect animals. The results showed 17.1% (7/41) dogs presented high levels of gamma-GT, but no difference between groups was observed. So, the serum level of gamma-GT is not a tool for diagnosis of visceral leishmaniasis in dogs.
