  1. 1. Edited by Vet-Abdulrhman Subhi Veterinary medicine Cairo University
  2. 2. -Babesia equi +General characters +Life cycle -Babesiosis +Diagnosis +Treatment +Control
  3. 3. FAMILY:Babesiidae Genus Babesia -Babesia equi -Babesia cabali
  4. 4. -Also called Theileria equi. (Because it form schizonts in the lymphocytes) -It is an intra-erythrocytic protozoa. -It multiply by binary fission. -They are small in size(2µm) with round, oval or double pear shaped. -some parasites divide into 4 organisms to form maltese cross. -It moves by gliding. -It is a heteroxenous parasite Vertebrate host Horse-donkey Invertebrate host (vector) 2 or 3 host hard tick
  5. 5. -It is transmitted trans-stadially by 2 or 3 host ticks( in which the larva is infected and is transmitted to the other stages – the parasite invade the whole body of the tick except the ovaries) -So the infected become free from the parasite after transmitting it to the vertebrate host -The infective stage is sporozoites - The sporozoite form schizont in the lymphocyte before invading RBCs.
  6. 6. Form schizont in lymphocyte
  7. 7. -It is also known as red water fever or piroplasmosis. -It is a highly pathogenic and highly distributed disease which can infect horses, donkeys, cattle, buffaloes, sheeps, goats, dogs, cats and human according to babesia spp . Clinical diagnosis Laboratory diagnosis
  8. 8. -1Fever Normal temoerature (37.5-38) Increase in body temperature
  9. 9. -2Anemia Due to hemolytic action of parasite Pale mucous membrane
  10. 10. -3Icterus Due to hemolytic jaundice

  17. 17. Imizol Imidocarb dipropionate salt Berenil Diminazene aceturate -Antipyretics -Treatment of anemia -Saline purgative in case of constipation
  18. 18. -By the control of the ticks -The newly imported horses must be checked from ticks -The infected horses must be treated from ticks to prevent babesia transmission -Horses may be sprayed by acaricides periodically
