“…suis. A number of subsequent reports have supplemented the intial study (60,61). These workers emphasized the need for intensive studies in other areas to contribute to the general knowledge and pointed out the likelihood of error in assuming that the factors which have proved to operate in the transmission of brucellosis in one locality are of equal importance in all areas.…”

Schroeder and Cotton (10) discovered in 1911 that milk obtained from certain cows, when injected into guinea pigs, produced lesions resembling tuberculosis. The same observation was made independently by Smith and Fabyan (11) in 1912 who called attention to the similarity of these "milk injection" lesions to those produced by B. abortus in guinea pigs. Both groups subsequently isolated the organism from cow's milk and identified it as B. abortw (10, 12). These findings caused Schroeder and Cotton (10) to propose that B. abortus might well be pathogenic for man. The question of human pathogenicity was further stimulated by Larson and Sedgwick (13) who demonstrated complement-fixing antibodies against B. abortus in the blood of children who drank raw milk. Cooledge (14) fed viable organisms in milk to several human volunteers without any evidence of clinical illness resulting. He was able to demonstrate B. abortus agglutinins in these individuals but concluded that they were absorbed from the ingested milk. The isolation of a similar organism from swine and its association with infectious-abortion in sows was first reported in 1914 by Traum (16). The link between these diverse observations was furnished in 1918 by Alice Evans (16) who found that Micrococcus meliten8is, the known etiologic agent of undulant fever which had first been isolated at autopsy by Bruce in 1887, was morphologically, culturally, biochemically, and serologically related to B. abortus. Following the suggestion of Meyer (17) in 1920, the generic name BruceUa found general acceptance, and after several years of confused terminology the caprine, bovine, and porcine organisms were designated, as proposed by Huddleson (18), as separate species: Br. mditensi8, Br. abortus, and Br. suis. Following the disclosure of the true relationship between Micro-coCCu melitensri (Bruce) and Bacillus abortus (Bang), Keefer (19) reported the first proved case of human brucellosis in this country of non-caprine origin. Other cases of non-caprine origin in the United States were soon reported by Gage and Gregory (20), Huddleson (21), and Carpenter and Merriam (22). Concurrent observations appeared in other countries (23). Although several of these early case reports indicated that contact with infected animals was a probable means of infection, and the original reports of the Commission on Mediterranean Fever pointed out that infection mav occur through small wounds of the skin, attention in this country centered on contaminated milk as a source of human disease. Evans (24), Fleischner and Meyer (26), Carpenter and Baker (26), and others (27, 28, 29, 30, 31) pursued the problem and demonstrated the widespread occurrence of Br. aboTtw in raw milk

“…The comparisons in attack rates noted above would seem to indicate that: (1) The degree or type of contact which the employees had with carcasses, carcass parts, or viscera had little bearing on the attack rates. (2) There are factors associated with the floor or area in which the employees worked that influenced the attack rates. …”
