...Pathogenesis. Only an incredibly small fraction of all bacterial species can cause disease. The rest play essential roles in the cycle of nature. Infectious bacteria differ from each other in several distinct respects: infectivity (i.e., the infectious does, ranging from a few cells of the tularemia bacillus to around 10-6 of the cholera vibrio); specific distribution in the body; virulence (i.e., the severity of the disease produced); and communicability from one individual host to another. These attributes depend on the coordinate activity of many genes, which are capable of independent variation. For our discussion the distinction between the ability...
This hypothesis, however, also failed to test out. CDC researchers screened the tissues for evidence of antibodies to bird-carried viruses. The results were negative. CDC tests found no indication of either plague or typhoid fever. So the search went on into more exotic terrain. Tests also ruled out tularemia (rabbit fever), a deadly tropical disease known as Lassa fever, and Marburg disease, a viral disease from Africa. Further screening seemed to dismiss fungi as a suspect; no fungus is known to produce the fatally fulminating pneumonia typical of Legion disease...
