rope it was mainly the states of the northern and centrat European
areas which succeeded in achieving the extermi nation or at least
the regression of brucellosis. (The origi nal plan to present the
conditions in Asia and Oceania, in cluding Australia, in maps as
weil, and thereby to achieve a comprehensive worldwide review of
the known and as certainable distribution of brucellosis, was not,
however, practicable. ) Information available from these parts of
the world, especially from Asia, is so fragmentary that the great
expense required for the compilation of the map did not seem
justified. On the other hand it seemed desirable to collate and
document these data which had been ac quired as a basis for future
research. It is tobe hoped that, at a later date, when more
comprehensive data become available, the Heidelberg Academy will be
able to decide to support a cartographic presentation of the
occurrence of brucellosis in these parts of the world as weil.
Last, but not least, the intensive research carried out by
bacteriologists had led to the discovery of new species of
Brucella, such as B. ovis, B. canis and B. neotomae. Further types
- such as Type 4 of B. suis which occurs in reindeer and caribou -
were identified. Though these new species and types, which are
undoubtedly to be classed with the brucellae, have achieved
regional significance in places, the three dassie species B.
