  1. Abscess by Dr. Nimer Khraim DVMS, BVMS, MVSc

  2. Abscess • It’s a localized infection with collection of bus in a cavity • Many microrganisms may be pyogenic in action and may cause abscess • Like staph., srept., corynebacterium pyogenes, E coli ..etc

  3. Abscess • Most of abscess begin as cellulites that become localized as an abscess form, the capillaries closed so the infection will kept localized

  4. Abscess • If the infection is highly virulent, the clots in small blood v. may destroyed • septic emboli may carried to other parts of the body proceeding abscesses, pyemia and septicemia

  5. Abscess • When the infection occur in the tissue the bacteria on the center of the inflammatory area destroy the T. • Defense become active and Leukocyte surround the infected area until local immunity is produced

  6. Abscess • The dead bacteria and many PMNc remain in the necrotic cavity and these together with cellular debris, lymph and serum produce Suppurative or formation of pus

  7. Abscess • The wall of abscess cavity consist of granulation T. that contain PMNc, leukocyte, lymphocyte, fibroblast and endothelial cells which activate the local immunity of the T.

  8. Clinical signs of the abscess

  9. Clinical signs of the abscess Redness • It can be determined in gray animal and only when the swilling is near the surface Heat • This due to increase flow of the blood through the affected part

  10. Clinical signs of the abscess Swilling • Always occur except in the location when the anatomy of the parts prevents expansion Pain • Due to P. on the nerve ending of the T.

  11. Clinical signs of the abscess • Some time abscess may lead to loss of function of the part of affected depending on the degree of destruction which is cause by the abscess

  12. Diagnosis Diagnosis • Depending on the clinical signs • Exploratory puncture specially in the mature abscess

  13. D.D D.D • Cyst • Hematoma • Distended synovial bursa • Abdominal hernia

  14. Treatment

  15. Treatment In acute mature abscess • Hasten the maturation abscess by application of counter irritant • Like iodine ointment 5%

  16. Treatment • In certain cases its advisable to open the abscess as soon as its diagnose • Like when the abscess localized near the vital organ or in the abdominal cavity or near the joint

  17. Treatment Surgical stapes • The skin over the abscess should be clipped and shear and antiseptic application • An open is made at the most dependant part of the swilling which is fluctuating and its better in the ventral part of the swilling to provide complete drainage of the abscess cavity

  18. Treatment • After the pus is removed the cavity should be checked for any F.B and necrotic T. should be removed • Then although flashing of the cavity should be made by suitable antiseptic like 10% povidone iodine or 1% chlor hixidene

  19. Treatment • Then the abscess cavity should be packed completely with gauze saturated with ten. Iodine 5% • This ten. Iodine gauze help in destruction of the lining membrane of abscess cavity and reduce the number of microrganisms

  20. Treatment • The gauze is removed in 24h and then the cavity again flashed with mild antiseptic solution

  21. Treatment Treatment in cold abscess or chronic abscess • Its developed very slowly due to chronic trauma to a certain area and it show little or no inflammatory reaction

  22. Treatment • Sometime they gradually undergo softening and burst causing ulceration to the skin and mucous membrane • The causes may be has a result of infectious dis. Like strangles, glander and T.B • The treatment is the same line of acute abscess

  23. Treatment • Counter irritant can be applied to render the abscess to acute form and bring the pus near the surface of the skin

  24. End
