The present a method for fast and accurate detection of abortion bacterial agents is the most priority of control and treatment for this disease. The aim of this study was the optimization of Real Time PCR for simultaneous detection of four of the most important bacteria causing abortion (<em>Campylobacter, Brucella, Yersinia </em>and<em> Salmonella</em>). 217 vaginal swab samples (132 samples from aborted and 85 samples from non-aborted ewes) were collected from some rural regions of Zanjan province. Pure samples of <em>Brucella, Yersinia </em>and<em> Salmonella</em> were also purchased from Persian Type Culture Collection (PTCC). After DNA extraction, specific primers of <em>Brucella</em>, <em>Salmonella</em> and <em>Yersinia</em> were examined on each purchased bacteria DNA sample. With 68 positive samples from 132 aborted ewes and 29 positive samples from 85 healthy ewes, <em>Campylobacter</em> was distinguished as a main factor of abortion in rural areas of Zanjan. The precision of <em>Campylobacters</em> primer was also assessed using Real Time PCR in different dilutions. The results showed that all bacteria in the same condition concurrently were amplified with Real Time PCR using specific primers and <em>Campylobacters</em> primer is able to identify and amplifying of bacteria in all dilutions even when just one copy is available.
