The authors give the differential characters of dysenteric amoebae and cells observed in the feaces of patients affected by recto-colitis. In this purpose, they recall the usefullness of cultures for both the presence and the possibility of determination of the Amoebae. In short, they deplore the misappreciation of these advantages.
A bibliographic survey is made of the cases of fasciolasis in Maghreb, and it can be concluded that: The notion of "epidemy", or better, of simultaneous cases, brought to the diagnosis evocation, to explorations by I.D.R. and to early treatment, before the excretion of eggs. Due to drug-efficiency, the coprological proof of the disease was generally missing in the old "epidemies" of the Maghreb. Isolated cases, in contrast, where the fasciolasic etiology was not evocated, could follow natural evolution and the proof by egg or adult discovery was possible in more than half the cases. Progress in immunology of fasciolasis made possible the diagnosis of less than 10 nw cases in Tunisia and Marocco. The authors report 2 new cases from the Constantine region (Algeria). The repartition of the ascertained cases and the possible ones is shown on a map.
At the occasion of the discovery of an amoebiasis focus in a psychiatric hospital (36,2 % of the patients were Entamoeba histolytica carriers), the authors insist on the importance of systematical and continued coprological controls. They observe that the two means of fight used together, the environment and the mass treatment, have strongly limited the propagation of parasitosis. By this way they note efficiency of the association of the medicinal polyvalent and contact amoebicides.
The values of eggs mensuration and results of coproculture have been compared for the identification of species of ancylostomia infestations. Results are confirming the necessity of coproculture for this diagnosis when the size of eggs is not inferior to 61 mu or superior to 72 mu. One case of morphological anomaly of some strongyloïd larvae of Necator americanus has been related.

A coprological investigation has been carried out on 268 refugees from the South Eastern Asiatic region. They were separated in two groups, one having received no treatment and the other having received a systematic treatment by diphetarsone, 1.-tetramisole and thiabendazole. In the first group, the infestation rate by protozoa (E. histolytica: 3,68 p. 100, G. lamblia: 9,2 p. 100, T. intestinalis: 9,81 p. 100) was lower than by helminths (A. lumbricoides: 17,44 p. 100, Ancylostomidae: 44,17 p. 100 and S. stercoralis: 25,58 p. 100) which were more frequently found. After a systematic treatment, effects on intestinal protozoa remained nearly inexistent. Indeed, the same percentages were found in the second group, whereas antihelmintic drugs were more active particularly on A. lumbricoides (4,94 p. 100) and S. stercolaris (5,49 p. 100). The compiled data have shown a high percentage of ancylostomidae infection which lead the authors to propose the systematic application of the described nematocide therapy.
The authors study the variation of the sensilles and the wing pattern of Culicoides circumscriptus Kieffer, 1918, they consider that Culicoides kirovabadicus Dzhafarov 1964, could be synonymous.
