Production of Immunity in Mice by Inhalation of Pneumococci
1. A definite degree of active immunity can be induced in mice through the repeated inhalation of live pneumococci. 2. Only slight immunity is induced in mice by the repeated inhalation of killed organisms.
متن کاملLocalization of Pneumococci in the Lungs of Partially Immunized Mice following Inhalation of Pneumococci
1. When mice are passively immunized by the intraperitoneal injection of antipneumococcus horse serum or actively by the injection of heat-killed pneumococcus cultures, and are then alcoholized and sprayed with a culture of pneumococci of the same type as that of the bacteria employed in immunization, a considerable number die with localized lesions in the lungs. 2. If instead of injecting immu...
متن کاملEarly Pulmonary Lesions in Partially Immune Alcoholized Mice following Inhalation of Virulent Pneumococci
1. The serial section examination of 71 partially immune alcoholised mice which were killed at intervals following the inhalation of virulent pneumococci showed pulmonary localisation in 7 or 9%. 2. In the case of the mouse the initial lesion of pneumococcus pneumonia is in the alveolar wall and the exudate into the alveolar lumen occurs secondarily.
متن کاملRespiratory input in inhalation experiments.
The definition of the respiratory input in experimental human exposure to volatile solvents was examined on theoretical grounds. The respiratory rate of input may be defined as the rate of uptake that equals the inhaled minus exhaled amount per minute. In the present paper the rate of respiratory input is defined as the rate of the functional intake (RFI) which equals the product of the inhaled...
متن کاملIntranasal Virulence of Pneumococci for Mice
1. Smooth colony pneumococci fresh from human beings, instilled in small doses into the nasal passages of special mice raised under standard conditions, brought about a characteristic infection and this spread to healthy contacts inciting in them the carrier state or fatal infection. 2. Differences in individual host response to the same dose of a given culture ranged from a complete refractory...
