Appearance and Incidence
The pathogenic agent is to be found everywhere except New Zealand. The bacterium is extremely sustainable and virulent: a single organism is able to cause an infection. The common way of infection is inhalation of contaminated dust, contact with contaminated milk, meat, wool and particularly birthing products. Ticks can transfer the pathogenic agent to other animals. Transfer between humans seems extremely rare and has so far been described in very few cases.
Some studies have shown more men to be affected than women, which may be attributed to different employment rates in typical professions.
"At risk" occupations include, but are not limited to:
- veterinary personnel
- stockyard workers
- farmers
- shearers
- animal transporters
- laboratory workers handling potentially infected veterinary samples or visiting abattoirs
- people who cull and process kangaroos
- hide (tannery) workers

Famous quotes containing the words appearance and, appearance and/or incidence:
“You speak of poverty and dependence. Who are poor and dependent? Who are rich and independent? When was it that men agreed to respect the appearance and not the reality?”

“Every natural fact is a symbol of some spiritual fact. Every appearance in nature corresponds to some state of the mind, and that state of the mind can only be described by presenting that natural appearance as its picture.”
—Ralph Waldo Emerson (1803–1882)
“Hermann Goering, Joachim von Ribbentrop, Albert Speer, Walther Frank, Julius Streicher and Robert Ley did pass under my inspection and interrogation in 1945 but they only proved that National Socialism was a gangster interlude at a rather low order of mental capacity and with a surprisingly high incidence of alcoholism.”
—John Kenneth Galbraith (b. 1908)
