[Immunity status of guinea pigs infected with Brucella L forms]

B. abortus L-forms injected subcutaneously into guinea pigs adapt in the lymph nodes of the animals in the absence of reversion to normal cells. Complete and incomplete antibodies belonging to macro- and microglobulins (IgM and IgG) were synthetized. The allergic transformation of the organism is faintly pronounced. After this form of infection guinea pigs become resistant to B. melitensis infection for 6 months (the term of observation).
