Non-specific humoral immunity in rabbits immunised with Chlamydia psittaci-Gocaltovo strain.

In this study we monitored parameters of non-specific humoral immunity in rabbits immunised with Ch. psittaci-Gocaltovo strain and looked for specific anti-Chlamydia antibodies. The results obtained indicated that the parameters evaluated, including activity of myeloperoxidase and the level and activity of lysozyme, manifested alterations earlier than positive titers of specific antibodies developed. This may indicate that alterations in parameters of non-specific humoral immunity can be used as accessory tests in the diagnosis of chlamydioses.
