ABSTRACT
Zoonosis is described as an infectious disease that is transmitted primarily from animals to humans. Several groups of pathogens with representatives that can cause zoonotic disease are described in their own chapters in this book. In this chapter, the authors briefly discuss the pathogens of the following zoonotic genera: Anaplasma, Bartonella, Borrelia, Brucella, Coxiella, Francisella, and Pasteurella. However, equine granulocytic anaplasmosis has been described as early as 1968 in the western United States and Canada and in dogs in 1982. However, not all species are present in all endemic locations and of the 11 genospecies only Borrelia andersonii, Borrelia bissettii, and Borrelia burgdorferi sensu stricto have been identified in North America. Some zoonotic pathogens, such as Bacillus anthracis, F. tularensis, and Brucella abortus have garnered renewed interests because of their potential role as bioterror agents.
