By B. C. Crowell' and R. W. Hammack'

Philippines, and the Biological Laboratory, Bureau

INTRODUCTION 



The incidence of intestinal parasites in the inhabitants of the 

 Philippine Islands has been the subject of investigation by 

 numerous workers since the American occupation of the Islands. 

 These investigations have been made largely from the clinical 

 standpoint, using the microscopic examination of the faeces as 

 the standard of the incidence. Among the works on the sub- 

 ject may be mentioned those of Garrison, (i) Garrison and 

 Llamas, (2) Garrison, Leynes, and Llamas, (3) Rissler and 

 Gomez, (4) Chamberlain, Bloombergh, and Kilbourne,(5) Wil- 

 lets,(6) and Musgrave and Clegg.('7) 



No report on any large series of cases in the Philippine 

 Islands has been made solely from autopsy investigations with 

 the aim of establishing the percentage incidence of intestinal 

 parasites. The present report is based on the findings in 500 

 consecutive autopsies performed in the department of pathology 

 and bacteriology. College of Medicine and Surgery, during the last 

 twelve months. The compilation in reality entailed the examina- 

 tion of 583 records, 83 of which were not utilized; the excluded 

 cases were those of infants under three months of age and those 

 in which the intestine was not examined on account of advanced 

 post-mortem changes or for other reasons. While the previous 

 clinical investigations have been performed for the most part in 

 certain selected regions or on certain selected classes of individ-
