抄録
Two attenuated strains of Mycoplasma pneumoniae, P24-S1 and P24-S11, were tested for their ability as a live vaccine to confer on hamsters immune resistance against challenge infection with a virulent strain of M. pneumoniae, FH-P24. Fifty percent protection was obtained by vaccination with the P24-S1 strain administered once or twice. In contrast, only 10% of the animals were protected by the P24-S11 vaccine even when it was given three times. Vaccination with the P24-S1 strain resulted in higher humoral and cellular immune responses than the P24-S11 did. These results suggest that the P24-S1 strain has the primary qualities a vaccine which may be used for protection against human mycoplasmal infection.
