Hemodynamics of Anaplasma marginale infection in calves Girolando

Abstract

The present study aims to study the hemodynamics of A.marginale infection in calves raised in São Cristóvão-SE Girolando. 24 calves (12 females and 12 males), bred in semi-intensive system were utilized. Large presence of ticks Boophilus microplus, low body condition, lethargy, pale mucous membranes, diarrheal stools and pyrexia was observed in calves. To combat the frame and anti-ectoparasitic, anthelmintic, imidocarb dipropionate and vitamin supplement. The animals were monitored for eight weeks to study haematological parameters and measurement of protein and fibrinogen, in addition to research hemoparasites after the imposition of treatments. The best observed in hematological status herd animals occurred on the fifth week (He:12,1x10⁶/mL, Hm: 10g/dL, VG: 33%, VCM: 27,5fL, HCM:8,3pg, CHCM: 30%) while the lowest value of WBC has been obtained in the last week (10.3 x 10⁶ / ml). 3.1% (6/192) of the blades to research hemoparasites was detected intraerythrocytic inclusion of corpuscles of A. marginale. Was observed in this study that the peak of clinical improvement occurs about four to five week after the initiation of treatment against A. marginale.
