Abstract

The objective of this experiment was to elucidate the aspects of differential circulatory cell responses during experimental coccidiosis in goat. A total of twenty newborn kids were selected; ten of them were infected with sporulated oocysts of the most pathogenic species of Eimeria and the remainder served as control. Blood samples were taken at 0 (before inoculation), 3, 7, 14, 17, 21, 24, 28 and 35 days post infection (dpi) and some hematological and fecal related parameters were measured. According to our data, except for a significant decrease at 24 dpi, packed cell volume (PCV) and hemoglobin (Hb) concentrations evidenced no substantial changes in the infected kids compared to controls. The percentage of the circulatory neutrophils showed remarkable increases from 7 to 24 dpi. Unlike neutrophils, the level of lymphocytes represented marked decreases from 7 to 24 dpi. In addition, circulatory eosinophils evidenced no statistical changes during the infection; however monocytes revealed a significant elevation only at 17 and 24 dpi. Substantial activations of neutrophils and lymphocytes indicate that these cells have key roles in either preventing or establishing primary infections with Eimeria in goats.
