At the urologist's office, the sandwiches were laced with botulism toxin, tuberculosis-causing Mycobacterium tuberculosis, and typhus-causing Rickettsia bacteria .
Rickettsia: In 1906, Howard Ricketts discovered that the bacteria that causes Rocky Mountain Spotted Fever is carried by a tick.
There are no known cases of human infection by the Rickettsia bacteria carried by N. salmincola.
1916 Pathologist Henrique da Rocha Lima identifies the causative agent (Rickettsia prowazeki) of epidemic typhus.
After a patient contracts epidemic typhus from the fecal matter of an infected louse (Pediculus humanus), the rickettsia can remain latent and reactivate months or years later, with symptoms similar to or even identical to the original attack of typhus, including a maculopapular rash.
Research in the 1920s and 1930s identified what appeared to be a new type of Rickettsia, isolated from ticks, that was able to pass through filters.
concinna can act as a vector for Francisella tularensis (tularaemia), Rickettsia sibirica (Siberian tick typhus), Rickettsia heilongjiangensis (Far-Eastern spotted fever), Virus of Russian spring-summer encephalitis (RSSE) and tick borne encephalitis (TBE).
The authors also argue that feral cats act as vectors for diseases that can impact domestic cats, wildlife and humans, examples include feline leukemia virus, feline immunodeficiency virus, fleas and ear mites (which are also carried by canines and wildlife), hookworms, roundworms, Bartonella, Rickettsia, Coxiella and Toxoplasma gondii, and that fecal matter has also been shown to degrade water quality.
