Abstract: In May and June 1951,the present authors carried out bacteriological examinations on dead-in-shell-chicks, chicks died before first feeding and brooding chicks at hatching plants and breeding plants in Sapporo. The results are summarized as follows : 1) Salmonella organisms were isolated from 52 cases out of dead-in-shell-chicks, 19 cultures of them were indentified with S. pullorum and the other 33 cultures with S. senftenberg. From 37 cases out of 225 chicks died before first feeding, 10 cultures of S. pullorum and 27 cultures of S. senftenberg were isolated, however, one case of the 37 was infected with both organisms (Tables 1,3,5,6,8). 2) In two breeding plants, Salmonella organisms were isolated from 303 dead brooding chicks out of 588 which died within 50 days after hatching. Among them, 218 chicks were infected with S. pullorum, 49 with S. senftenberg and 17 with S. bareilly. Besides, some mixed infections were observed as follows : 8 with S. pullorum and S. senftenberg, 6 with S. pullorum and S. barilly, 4 with all of the above three organisms (Tables 2,4,8). 3) Newly isolated cultures of S. bareilly were proved to have the following phases : 5 cultures, I and II phases; 5 cultures, phase II and artificially induced phase I; 17 cultures, phase I and artificially induced phase II. 4) Senftenberg infections in brooding chicks occur most frequently during 5∿10 days after hatching and then they decrease rapidly; Pullorum infections become highest during 15∿20 days after hatching, then decrease gradually but do not disappear even up to 50 days. 5) The spread of the organism in dead chicks seems to be different corresponding to the types of the infectious agents.
