Objective: To study blechemichal properties and comparing current 
antibiotic resistance of S. abortusovis isolated from sheep in Ch 
Bakhtiaiy province and study the prone to R - factor transferability. 
Design: Comparative study 
Samples: Thirty four strains isolated from Chaharmahal-Bakhtiary . 
in 1999-2000 
Procedure: Biochemical tests were performed with standard diagnestic  
tests, antibiotic susceptibility and it’s transferability were examined. 
Results: All strains were resistant to Ampicillin (Am) and 
Amoxicillin (Amx). Although the Streptomycin (S) after the Am 
and Amx was the most common resistance. Resistance to Amicacin 
(AN) and Tetracyclin (Te) were very low (about 2%). All strains , 
were susceptible to Chloramphenicol (C), Nalidixic Acid (Na), 
Kanamicin (K) and Enrofloxacin (En). Just in one case the profile 
of Am - Amx - Cotrimaxazole (SXT)- AN- Te was developed. 
Among the total isolates, 3 cases were able to transfer some part 
of their resistance factors. In all three cases only resistance to 
Ampicillin were transmitted. 
Conclusion: Antibiotic resistance in S. abortusovis strains isolated 
from Iran is not that high and rarely were transmited to other 
bacteria. This phenomenon may be related to the difficulties  
of drug administration in sheep and got flocks.
