Transcript of "Haemoproteus Columbae"

  1. 1. Haemoproteus columbae Submitted by P. Mahalingam BVM 06066
  2. 2. Scientific classification <ul><li>Domain: Eukaryota </li></ul><ul><li>Superphylum: Alveolata </li></ul><ul><li>Phylum: Apicomplexa </li></ul><ul><li>Class: Aconoidasida </li></ul><ul><li>Order: Haemosporida </li></ul><ul><li>Family: Plasmodiidae </li></ul><ul><li>Genus: Haemoproteus </li></ul><ul><li>Species: columbae </li></ul>
  3. 3. GENUS INTRODUCTION <ul><li>Genus created was by Kruse in 1890 </li></ul><ul><li>Greek : Haima - blood </li></ul><ul><li> Proteus - a sea god ( who had the power of assuming different shapes ) </li></ul><ul><li>Synonyms of Haemoproteus : </li></ul><ul><ul><ul><li>Halteridium , </li></ul></ul></ul><ul><ul><ul><li>Haemocystidium </li></ul></ul></ul><ul><li>Intracellular parasites - erythrocytes </li></ul><ul><li>Pseudomalaria similarities with Plasmodium species </li></ul>
  4. 4. Haemoproteus columbae <ul><li>Host : Pigeon ( Columba livia ), doves. </li></ul><ul><li>Vector : Pseudolynchia canariensis - louse flies ( Hippoboscidae ) </li></ul>
  5. 5. Morphology <ul><li>Gametocyte partially surrounds the cell’s nucleus </li></ul><ul><li>Multiple, refractile, golden-brown particles of hemozoin pigment. </li></ul>
  6. 6. Pseudolynchia canariensis - louse flies ( Hippoboscidae )
  7. 7. Life cycle <ul><li>salivary glands of the vector </li></ul><ul><li> </li></ul><ul><li>sporozoite Infective stage </li></ul><ul><li>bites a new host </li></ul><ul><li>Endothelial cells of blood vessels & lung , liver and spleen </li></ul><ul><li>asexual reproduction </li></ul><ul><li>schizonts </li></ul><ul><li>Numerous merozoites </li></ul><ul><li>penetration </li></ul><ul><li>erythrocytes </li></ul><ul><li>Mature either macrogametocytes or microgametocytes </li></ul><ul><li>another blood-sucking insect </li></ul>
  8. 8. Life cycle – cond. <ul><li>ingested by another blood-sucking insect </li></ul><ul><li>sexual reproduction in the midgut of the insect </li></ul><ul><li>to produce oocysts </li></ul><ul><li>rupture and release numerous sporozoites </li></ul><ul><li>invade the salivary gland </li></ul><ul><li>subsequent infection for another host </li></ul>
  9. 9. Life cycle
  10. 10. PATHOGENESIS <ul><li>To produce subclinical infections </li></ul><ul><li>E nlarged gizzards. </li></ul><ul><li>Enlargement of the spleen , liver and kidneys </li></ul><ul><li>May appear chocolate-brown due to hemozoin deposition </li></ul><ul><li>Infected birds may suffer from reluctance to move, </li></ul><ul><li>Ruffled appearance, </li></ul><ul><li>Prostration And Death. </li></ul><ul><li>Include Parasitemia And anemia. </li></ul><ul><li>Large megaloschizonts may be present in skeletal muscles, </li></ul><ul><li>Particularly those of the thighs and back. </li></ul><ul><li>The average cumulative mortality for flocks experiencing outbreaks may be over 20%. </li></ul>
  11. 11. Diagnosis <ul><li>Peripheral & Cardiac Blood smear examination. </li></ul><ul><li>Liver & spleen impression smear were stained by Giemsa </li></ul><ul><li>It shows a typical Halter shaped Gamonts in RBCs </li></ul><ul><li>PM – Examination </li></ul>
  12. 12. Treatment and Control <ul><li>Antimalarial drugs - chloroquine may be useful </li></ul><ul><li>Control : </li></ul><ul><ul><li>By eliminating the vector population </li></ul></ul><ul><ul><li>Habitat management </li></ul></ul><ul><ul><li>Application of insecticides </li></ul></ul><ul><ul><li>Use of ventilation fans </li></ul></ul>
