[ study on the hepatic abscess of slaughtered cattl in shahrekord abattoir]

ABSTRACT

To determine occurrence and also bacterialcauses of hepatic abscess of sacrificed cattle in shahrekodabattoir.Cross Sectional study.Five hundreds sacrificed cattle.During this study inspection of 500 sacrificedcattle for presence of hepatic abscess was carried out inslaughter house. After observing the hepatic abscess, animal's sex, age, production, pregnancy and also abscesscharacterizations [number, size, location], recorded andwhole abscess was dissected from the liver and transferredto the laboratory. Aerobic, anaerobic and microaerophilicbacterial cultures from hepatic abscesses were carried outusing standard methods.Chi- Square statistical test.Thirty three cattle [6.6%] out of 500 inspectedsacrificed cattle had hepatic abscess, from which 18abscesses were in females [54.5%] and 15 abscesses werein male [45.5%]. Twenty three livers out of 33 infectedlivers had only one abscess [69.69%] and 10 livers had 2 ormore abscesses [30.30%]. Fusobacterium necrophorumwas isolated as unique bacterial cause of 21 hepaticabscesses [63.63%]andArcanobacteriumpyogenes wasisolated from only 9 abscesses [27.27%].The results of the present study showed that Rnecrophorum is the most important bacterial cause ofhepatic abscesses in cattle in shahrekord.
