CHAPTER XXnBACTEMA IN PNEUMONIA Klebs in 1875 called attention to the presence of bacteria inpneumonia, and in 1882 Friedlander developed a bacillus fromthe lung tissue of a pneumonic person which he thought wasa coccus, and called it pneiunococcus. In 1886 A. Frankel and Weichselbaum proved that thisorganism was not constant—^in fact, was rare. A. Frankel obtained in the majority of cases of pneumoniaan organism that he had described in 1884 under the nameof sputum-septicemia micrococcus. Weichselbaum called this Diplococcus pneumonim, and be- iS6 ESSENTIALS or BACTERIOLOGY.
