In parenteral and intranasal immunization with M. pneumoniae of guinea pigs, along with seroconversion, there was observed development from the 15th-20th day of hypersensitivity of delayed type; this hypersensitivity was revealed by positive skin tests and by the reaction of specific transformation of the peripheral blood lymphocytes. An increased reactivity of the smooth muscles of the intestine of parenterally immunized animals was revealed. With the aid of the test of alteration of blood neutrophils in vitro there was found development of specific sensitization of the organism to M. pneumoniae in the patients with mycoplasma pneumonia.
