The results of current study showed that salmonella species isolation from cow in rate of 13.3% by culture methods, high of them from aborted cows in rate of 22.2%. Result of PCR test showed that salmonella typhimurium and salmonella Dublin detection in rate of 55% and 25% respectively while other salmonella species detected in rate of 20% from total salmonella isolates .
