Immunological and cytogenetical changes were studied in mice-recipients of CBA and C57BL/6 lines as well as modifications of their behavior appearing as a result of action of various stressors. Post-stress volatile excretions of CBA males cause led to a pronounced immunosuppression in males-recipients of both lines. This resulted in a decrease of capability for immune response of the stressed mice to sheep erythrocytes. Besides, in young males of the CBA line, frequency of chromosome aberrations in bone marrow cells increased statistically significantly after stressing by syngenec volatile excretions of mature animals. Attractive properties of volatile excretions of the CBA and C57BL/6 line males were studied. In norm, animals of both lines prefer syngenic odors of intact males donors. However, for the CBA line males, post-stress excretions from males-donors of both lines became more attractive than excretions from intact animals. Also revealed were interline differences in incidence of choice of syngenic and allogenic post-stress excretions. This can be explained both by different stress-reactivity of animals-donors and differences of recipients of the studied genotypes in selectivity to olfactory stimuli. An importance of olfactory stresses and of the revealed interline differences for explanation of some micro-and macroevolutionary synecological processes in the domestic mouse is discussed.
