Prevalence of Chlamydia suis in population of swine in Poland and comparison of complement fixation test and PCR used in the diagnosis of chlamydiosis.

摘要

The 61,020 samples of swine serum and vaginal swabs were collected in 2007-2009. The sera were examined by complement fixation test (CFT). Positive results were found in 277 pigs. The percentage of positive serological results in subsequent years was: 0.4%, 0.47%, and 1.65%, respectively. The vaginal swabs (n=277) selected from pigs diagnosed as positive in the CFT were tested by PCR. Occurrence of Chlamydia suis was confirmed in PCR in 200 cases. Statistical analysis ( chi 2 test, Person and Cramer correlation coefficient) demonstrated that both methods were coincident in the diagnosis of C. suis infection in swine.
