188 Coccidia parasitic in man 
worker engaged in the study of the same class of cases in this country (cf. 
Dobell, 1917) 1 . 
Since the publication of WenyoiVs original and only case, the parasites 
have been found again— so far as I have been able to ascertain with certainty 
—by only one observer. This was Roche (1917), who found three cases of 
infection among 893 military patients, all suffering from dysentery or 
diarrhoea, whom he examined at Salonika. The parasites were recorded 
merely as Eimeria ”; but Captain Roche, in answer to my inquiries, kindly 
informed me that they were, so far as he could judge, identical with the forms 
described by Wenvon. 
There are thus only four cases of infection with this organism known up to 
the present; and when the very large number of persons examined is taken 
into account, it must therefore be regarded as extremely rare. Of its patho¬ 
genicity nothing is known, and methods of specific treatment for the infection 
are still untried. It is possible that a severe infection may give rise to an 
enteritis, since the habitat of the parasite is probably the mucous membrane 
of the small intestine: but if we exclude the highly doubtful cases of Eimer 
(1870) the organism has not yet been found in the tissues, and the fact that 
the recorded cases of infection were found among patients suffering from 
intestinal complaints is probably without significance. Our knowledge of the 
geographical distribution of the parasite is limited to the fact that hitherto 
it has only been recorded in persons from the Eastern Mediterranean region. 
(3) Eimeria oxyspora n. sp. 
(See Plate VIII, fig. 3.) 
I propose this name for a coccidial parasite whose oocysts I have found in 
human faeces, and which has not been previously described. As in the case 
of E. wenyoni there is a remote possibility that this is the organism which was 
seen in the intestine by Eimer (1870); but there is nothing to support such a 
supposition. And of the other coccidia previously recorded there is none 
which can be regarded Avith any plausibility as belonging to this species. 
Up to the present I have found this organism in the faeces of a single 
individual only. The patient is a young man who has been in South Africa, 
Ceylon, and India, and has suffered since 1912 from amoebic dysentery of a 
chronic relapsing type, which has hitherto proved extremely refractory to 
e/very kind of treatment. He has been for some time under the care of my 
friend Dr G. C. Low (now Temporary Major, I.M.S.), with whom I have studied 
his amoebic infection. A brief account of the case from this standpoint has 
already been published. (Vide Low (1918), Case 2, “B. W.,” p. 164.) I have 
made an exhaustive examination of the stools of this patient (on over forty 
occasions in the course of the last year) but ha Am found the coccidial parasite 
in them only twice, and then in extremely small numbers. 
1 The “Eimeria sp.” noted by Dobell and Stevenson (1917) and Dobell (1917) both refer to 
Wenyon’s original case.
