HUMAN INTESTINAL PROTOZOA IN THE NEAR EAST 



SECTION IV. 



CASE HIRST, aged 46. Patient, who had previously served in India, South Africa and Egypt, 

 left England in November, 1914, for France, where he remained till he was transferred to the 

 Peninsula in August, 1915. He was there for nine weeks and was then in Mudros for two 

 months, after which he came to Egypt, where, on May 10, during the routine examination of 

 cooks in Mazarita Camp, he was found to be a carrier of E. histolytica. There was no history 

 of dysentery. Patient was kept under observation in hospital, and here the E. histolytica cysts, 

 which were of the small variety, disappeared from the stool and did not recur during one month's 

 control. During the observation, the stool being examined every day, the patient suddenly 

 developed an infection of Waskia intestinalis . It is curious that the only other case of infection 

 which has been met with was then under observation in the same ward and occupying the bed 

 next but one to this patient. It seems probable that the one case contracted the infection from 

 the other while in hospital. The case was eventually discharged from hospital without treatment 

 of the E. histolytica infection, which had not recurred. There were no symptoms attributable 

 to it or to the Waskia infection, which was still present.
