There was no prepondcrauce of amoehic infectious in either sex or 

 in any age group. No infections appeai'ed in children under 2 years 

 okl. 



CLINICAL MANIFESTATIONS. 



Of 1,122 patients attending the clinic during tlie three niontlis it 

 was in progress, 60 had intestinal disorders. Of tliese 35 were diag- 

 nosed as cases of dysentery. Of the 35 cases of dysentery, 12 had 

 amcehcc in their stools, leaving 23 cases of dysentery in which aincebce 

 could not be found and 15 patients with ama'hce in their stools who 

 showed no symptoms of amoebic enteritis. In other words, a definite 

 diagnosis of amoebic dysentery was made in only 12 (about 1 per cent) 

 of the total 1,122 persons attending the clinic. Of these 12 cases, 5 

 liad flagellates in their stools as well as amoshw. 



One other case with dysenteric symptoms had encysted organisms in 

 his stool which were probal:)ly aiiia'hw. The remaining cases with en- 

 cysted organisms had no symptoms of dysentery. 



There was one questionable case of liver abcess with no history of 

 previous dysentery. The patient died in April but consent for an 

 autopsy could not be obtained. 



To summarize, there were 27 patients of the 1,000 examined, or 2.7 

 per cent, who showed motile aina'Ixe in their stools. There were 35 

 cases, or 3 per cent, of 1,122 patients examined which were clinically 

 diagnosed as dysentery. There were 18 patients (13 including the one 

 with encysted forms) with amwbw in their stools and with dysenteric 

 symptoms, or about 1 per cent of those examined. Fifteen had aincebce in 

 their stools without dysenteric symptoms. Twenty-three had dysentery 

 Avithout ainn'ba'. 



I'T-.-VGELLATES AiXU CILIATHS. 

 5.5 per cent. 0.2 per cent. 



The figures for these infections are not considered to be of mucli 

 statistical value. Both flagellates and ciliates appeared much less fre- 

 qiiently than we have been accustomed to flnd them in other series of 

 examinations in the Philippines. At Bilibid Prison we found 23 per 

 cent of the prisoners to have these organisms in their stools. 



Of the two cases with ciliates, the organism in one appeai'ed to be 

 Balantidiuin coli, in the other it more closely resembled the saprophytic 

 Parama'citoii conuuonly found in water and may have been a contamina- 

 tion. In both cases the ciliates had (lisap])eai-e(l aftt'r treatment for 

 Ascaris. 



The identity of the flagellates was not determined in tlie majority of 

 the cases. Most of those studied appeared to be Ci'rconionas lioiuinis 

 and it is pi'o])able that most of the infectious weie with this organism.
