In this paper the case of infection in patient D.H. with B. aertrycke would in current medical terminology be called typhoid fever due to infection by Salmonella enterica serotype Typhi; the case of infection in patient J.A.M. would be called paratyphoid fever due to infection by Salmonella enterica serotype Paratyphi B. The name of the bacterial species was changed. In 1928 medical experts were not entirely sure that B. aertrycke consisted of Salmonella.
