title: Bovine babesiosis in Sicily: preliminary study on pathology.
abstract: In this study, the authors report the preliminary pathological features of an outbreak of spontaneous babesiosis detected in a group of thirty-five, five to six months-old Simmenthal calves imported in Sicily in November 1998. Five of them showed fever, anaemia, haemoglobinuria, inappetence, depression, thirst, swollen lymph-nodes and poor body conditions a few days after being introduced in the farm. Several ticks were present particularly at the basis of the horns and near the ears of the sick animals. Blood smears, stained with May-Grunwald-Giemsa, showed several pyriform merozoites in the red blood cells referred to Babesia bigemina parasites; all ticks collected were identified as Dermacentor marginatus. Gross post-mortem examination and histopathological observations revealed severe involvement of kidneys, liver, lungs, spleen and lymph-nodes. The pathogenesis of the referred features in a spontaneous fatal case observed is discussed.
