In many instances a given infectious disease common to one species has its counterpart in other host species. Some infections are host specific while others are not. In Table I it will be noted that human Pasteurellosis is the type representative of a number of similar infections in other species. In the case of Brucellosis, the three main types of Brucella organisms are capable of infecting at least five species of hosts.
