 Passage 2:In 1880, the Commission concluded that the solution of yellow fever causality must await further progress in the new science of bacteriology. Sternberg was soon sent to New Orleans to investigate the conflicting discoveries of Plasmodium malariae by Alphonse Laveran, and of Bacillus malariae by Edwin Klebs and Corrado Tommasi-Crudeli. His report (1881) declared that the Bacillus malariae had no part in the causation of malaria. The same year—simultaneously with Louis Pasteur—he announced the discovery of the pneumococcus, eventually recognized as the pathogenic agent of lobar pneumonia. He was the first in the United States to demonstrate the Plasmodium organism as cause of malaria (1885) and to confirm the causitive roles of the bacilli of tuberculosis and typhoid fever (1886). He was the first scientist to produce photomicrographs of the tubercule bacillus. He was also the earliest American pioneer in the related field of disinfection in which he began with experiments (1878) with putrefactive bacteria. This work was continued in Washington and in the laboratories of Johns Hopkins Hospital in Baltimore, under the auspices of the American Public Health Association. For his essay "Disinfection and Individual Prophylaxis against Infectious Diseases" (1886), later translated into several languages, he was awarded the Lomb Prize. He oversaw creation the US Army enlisted hospital corps ("medics") in 1887.
 Passage 3:In 1853, the territory was reduced by the creation of the Diocese of Grahamstown in the eastern parts of the Cape Colony and the Diocese of Natal in the Colony of Natal. In 1859, the Diocese of St Helena was created for Saint Helena and Ascension Island. In 1863, the Diocese of Bloemfontein was created, taking over all the territory north of the Orange River and the Drakensberg mountains. In 1866, J. Harries Thomas was archdeacon of Cape Town and H. Badnall, archdeacon of George; and N. J. Merriman, archdeacon of Bloemfontein (by then separated) was still a canon of Cape Town cathedral. The territory of the Cape Town diocese was further reduced in 1911 by the creation of the dioceses of George and Kimberley and Kuruman. Finally, in 2005 the diocese was divided into three, with the part to north of the city of Cape Town becoming the Diocese of Saldanha Bay and the part to the east of the city becoming the Diocese of False Bay.
