The purpose of the study was to set up a method for cultivation of C. pneumoniae from infected mouse tissue in Hep2 cells. We also evaluated a new reagent, Chlamatis, which is considered to increase the detection sensitivity of the bacterium with both PCR and cultivation. All 10 serum samples treated with Chlamatis were negative for C. pneumoniae in PCR. The cultivation of tissue was found to work without problems. The yield of the bacteria was highest at the speed of 30 Hz using homogenization with TissueLyser. Mice infected with C. pneumoniae were killed at days 4, 8, 20 and 40. The highest yields of C. pneumoniae were found at days 4 and 8 using PCR with all infected mice. The results obtained with PCR and cultivation confirmed each other to a large extent. For heart tissue, PCR positive mice were found only at days 4 and 8. The number of PCR positive lung samples confirmed to a large extent the number found by cultivation, except for mice killed after 4 days and 40 days wher...
