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
