STOOL CULTUBES, 19 POSITIVE, 498 NEGATIVE, AND URINE OULTXJBES, 9 POSITIVE, 



329 NEGATIVE. 

 • 



Stool and urine specimens were smeared over the surface of Petri 

 dishes containing Endo medium. Cultures from the excreta were rarely 

 employed for diagnosis. Nearly all of those shown in the table were 

 made during convalescence to detect possible carriers, three negative 

 cultures at six-day intervals being required before a soldier was returned 

 to duty. These facts account in the main for the low proportion of 

 positive findings. Another factor which must be considered is that 

 the stools and urines in many cases had come a long distance. Our 

 experience, both practical and experimental, has been that after a few 

 days no typhoid bacilli can be obtained by cultural methods from a 

 stool, whether naturally or artificially inoculated with Bacillus typhosus. 



CHAEACTER OF TYPHOID ORGANISM ISOLATED IN THE PHILIPPINES. 



At the end of 1908 this Board had found tlie blue strain of typhoid in 5 

 patients in the Philippines and expressed the opinion that the prevailing type 

 of organism in the Philippine Islands might be one which produced primary 

 acidity in litmus milk followed after several days by alkalinity. Further ex- 

 perience has not confirmed this view. During nearly two years we have isolated 

 only one blue typhoid organism from either a native or a white man, and
