[Parasitologic study of feces: simultaneous performance of Faust's, Janecko-Urbanyi's and Ritchie's concentration technics].

The authors propose the simultaneous use of Faust's, Janeckso-Urbanyi's and Ritchie's techniques according to a protocol which combines the effectiveness of the three techniques, with a saving in reagents, a significant simplification of the manipulations (a single dilution of the stools, a single straining and a total of three centrifugations) and the possibility of conducting valid comparative studies, as the three techniques are performed from the same faecal aqueous suspension.

[Changes of serum lipoproteins during the course of human malaria (author's transl)].

Triacylglycerides (TAG), total cholesterol (TC) and serum lipoproteins (SLP) were studied during the course of 12 cases of human malaria and one case of simian inui malaria. The erythrocytic schizogony induced quickly an increase of TAG, a decrease of TC and modifications of SLP such an increase of VLDL parallel with a decrease or a disappearance of HDL. These modifications, always clear-cut, were not correlated with the intensity of parasitaemia or the species of Plasmodium. They were transient but longer than those described in connection with experimental rodent malaria. The changes of HDL could be associated with defective triglyceride removal of the plasma compartment due to an inhibition of the lipoprotein lipase induced by the parasite.

The influence of prostaglandins and vasoactive amines on the intestinal phase of experimental trichinellosis in CBA mice and Wistar rats.

The intestinal phase of experimental trichinellosis in CBA mice and Wistar rats is modified by the intraduodenal injection of prostaglandin (PG) E1 and, to a greater extent by PG E2. The resulting changes are dose-dependent and are a function of the point of the infectious cycle at which the injection is performed. Three dose-related phenomena are thus observable: a delay, an acceleration of the process of expulsion of adult worms or no effect, the latter arising if the prostaglandins are injected later in the cycle. Under the same conditions, no significant effects are exerted by PG A, B or F, by histamine or by serotonin.

Case report: recovery of Calliphora vicina first-instar larvae from a human traumatic wound associated with a progressive necrotizing bacterial infection.

Human myiasis caused by Calliphora vicina is rare in Europe. Here we report a case of C. vicina infection occurring in the traumatic leg wound of a healthy 21-year-old man. Firstly, a progressive necrotizing infection developed in the wound despite administration of antibiotics. Aeromonas hydrophila was isolated from the wound samples. Secondly, during debridement, C. vicina first-instar larvae were isolated from the wound. To our knowledge, this is the first European case of C. vicina wound myiasis associated with severe A. hydrophila infection.

[Cyclospora cayetanensis: review of an emerging intestinal pathogen].

Cyclospora cayetanensis is an emerging pathogen. It is a new human coccidian agent of intestinal disease. Twenty years ago, the first known human cases of cyclosporiasis were reported in the medical literature. Cyclosporiasis occurs in persons of all ages and either in immunocompetent or immunocompromised hosts. The most characteristic feature of this infection is a syndrome of acute or chronic diarrhea. This parasite has a world-wide distribution. In previous reports, Cyclospora cayetanensis was associated with prolonged diarrhea in travellers, returning from developing countries. However, Cyclospora infection has recently been reported in non travellers in the United States and Canada. Cyclospora can be transmitted by ingestion of water or food contaminated with oocysts. The life cycle of Cyclospora cayetanensis is not fully known. Diagnosis of cyclosporiasis is made by direct examination of stool samples. To date, oral trimethoprim-sulfamethoxazole is the only effective treatment for Cyclospora infection.

[Morphology and infectivity of gametocytes of Plasmodium inui].

The authors report biomorphological changes of Plasmodium inui gametocytes during the natural infection of spleenless Macaca fascicularis. The infection was controlled up to the 42th day by smears produced by pricks into their ears (P.O.) and on blood taken at the same time by A. stephensi (P.M.). The first oocystes appeared on the 8th day after the infection in mosquitoes fed on the monkey parasitised in the eight day after splenectomy, as gametocytaemia was not detectable yet in the P.O. smears. The infectivity of gametocytes is highest on the 13rd day for a 152/10(4) parasitaemia. The first sporozoites appeared on the 18th day at 25 degrees C after the infecting meal. The sporozoites were infecting for a second monkey. Four morphological types (O, I, II and III) gametocytes were identified. They corresponded to the same types previously described in rodent Plasmodium. The maximum of infectivity coincided with a sudden increase in mosquitoe macrogametocytaemia; on the other hand the infectivity was very weak during the following peek of macrogametocytaemia which corresponded however to the maximum of parasitaemia (1 318/10(4) 18 days after splenectomy). When infectivity was important, there was a greater number of type O and I gametocytes in P.M. than in P.O. Eventually, the behaviour of P. inui gametocytes is, for the mainly, almost the same as that of rodent Plasmodium. However, it is to be noted that the identification of the 4 morphological types in P. inui is easier in macrogametocytes than in microgametocytes. The reverse had been observed in rodent Plasmodium.
