(1) Bacteriological examination of 1078 enterica-suspect cases showed that 112 (i.e. 10 per cent.) were due to Bacillus asiaticus Castellani. In the same series 12 per cent. were found to be due to B. typhosus or B. paratyphosus (A or B).
(2) The distribution of cases is widespread, both in time and space, and there is no special incidence on sex or age-group.
(3) The symptomatology of asiaticus parenteric fever is detailed and a description is given of the causal organism.
(4) There is some group-(agglutination) relation between B. asiaticus and the paratyphoid-Gaertner subgroup.
(5) Parenterica due to “intermediate organisms” other than B. asiaticus is believed to exist in Egypt. These will be dealt with in a later communication.
(6) Early haemo-culture in all enterica-suspect cases should be considered the diagnostic method par excellence. If the blood develops immune bodies as well, the diagnosis becomes definite.
