Experimental Studies on Pneumococcus Infections
1. Phagocytosis of pneumococci in vitro runs parallel with phagocytosis in vivo. 2. Virulence depends not only on resistance to phagocytosis, but also on the ability to grow in the body of the animal. 3. The biological reaction of the pigeon to pneumococcus infection does not differ from that of the mouse. 4. The "immunity" of the pigeon to pneumococcus infection is due to its normal high tempe...
متن کاملExperimental Studies on Pneumococcus
The inefficiency of specific sera in the treatment of pneumonia must be attributed in part at least to the lack of exact knowledge of the nature of the infection and the processes whereby the human organism protects itself. To ascertain detailed facts regarding pneumococcus infection one must resort to laboratory animals, none of which so far as is known reacts to such infections in identically...
متن کاملStudies on Host Factors in Pneumococcus Infections
The power of specific antipneumococcus serum to protect rabbits against infection with Type I Pneumococcus has been studied with reference to the capacity of the animal to utilize the specific antibodies. Under conditions ensuring relatively controlled genetic factors it was found that heavier animals and those with high white blood cell counts are much better able to utilize the passively conf...
متن کاملStudies on Blood Changes in Pneumococcus Infections
In the occasional cases of pneumonia which show a decrease in the oxygen capacity of the blood, the decrease is probably due to a formation of methemoglobin. The latter is removed from the circulation, however, as rapidly as it is formed, so that it can seldom be detected even qualitatively, and is probably never a cause of cyanosis.
متن کاملStudies on Pneumococcus Immunity
1. Active immunity against many lethal doses of Pneumococcus Types I, II, and III may be produced in mice by two or three subcutaneous injections of the homologous type of pneumococcus saline vaccine. 2. Mice may be actively immunized with the protein fraction obtained by treating pneumococci with anhydrous sodium sulfate or by solution of pneumococci in bile salts and precipitation with alcoho...
