Transcript

  • 1. Haemoproteus columbae Submitted by P. Mahalingam BVM 06066
  • 2. Scientific classification
    • Domain: Eukaryota
    • Superphylum: Alveolata
    • Phylum: Apicomplexa
    • Class: Aconoidasida
    • Order: Haemosporida
    • Family: Plasmodiidae
    • Genus: Haemoproteus
    • Species: columbae
  • 3. GENUS INTRODUCTION
    • Genus created was by Kruse in 1890
    • Greek : Haima - blood
    • Proteus - a sea god ( who had the power of assuming different shapes )
    • Synonyms of Haemoproteus :
        • Halteridium ,
        • Haemocystidium
    • Intracellular parasites - erythrocytes
    • Pseudomalaria similarities with Plasmodium species
  • 4. Haemoproteus columbae
    • Host : Pigeon ( Columba livia ), doves.
    • Vector : Pseudolynchia canariensis - louse flies ( Hippoboscidae )
  • 5. Morphology
    • Gametocyte partially surrounds the cell’s nucleus
    • Multiple, refractile, golden-brown particles of hemozoin pigment.
  • 6. Pseudolynchia canariensis - louse flies ( Hippoboscidae )
  • 7. Life cycle
    • salivary glands of the vector
    • sporozoite Infective stage
    • bites a new host
    • Endothelial cells of blood vessels & lung , liver and spleen
    • asexual reproduction
    • schizonts
    • Numerous merozoites
    • penetration
    • erythrocytes
    • Mature either macrogametocytes or microgametocytes
    • another blood-sucking insect
  • 8. Life cycle – cond.
    • ingested by another blood-sucking insect
    • sexual reproduction in the midgut of the insect
    • to produce oocysts
    • rupture and release numerous sporozoites
    • invade the salivary gland
    • subsequent infection for another host
  • 9. Life cycle
  • 10. PATHOGENESIS
    • To produce subclinical infections
    • E nlarged gizzards.
    • Enlargement of the spleen , liver and kidneys
    • May appear chocolate-brown due to hemozoin deposition
    • Infected birds may suffer from reluctance to move,
    • Ruffled appearance,
    • Prostration And Death.
    • Include Parasitemia And anemia.
    • Large megaloschizonts may be present in skeletal muscles,
    • Particularly those of the thighs and back.
    • The average cumulative mortality for flocks experiencing outbreaks may be over 20%.
  • 11. Diagnosis
    • Peripheral & Cardiac Blood smear examination.
    • Liver & spleen impression smear were stained by Giemsa
    • It shows a typical Halter shaped Gamonts in RBCs
    • PM – Examination
  • 12. Treatment and Control
    • Antimalarial drugs - chloroquine may be useful
    • Control :
      • By eliminating the vector population
      • Habitat management
      • Application of insecticides
      • Use of ventilation fans
  • 13. References
    • Veterinary protozoology -by Norman D. Levine - 1985 - Technology & Engineering - 414 pages
