[Primary amebic meningoencephalitis: 1st case observed in Madagascar].

The primary amebic meningoencephalitis is an acute suppurative infection that involves both the brain and the meninges. It is caused by Naegleria fowleri and is a very rare and fulminating condition, so far nearly always fatal. We report the first case in the area of Southern part of Indian Ocean that occured in a 7-year old French boy living in Madagascar.

Prospective assessment of a new polymerase chain reaction target (STEVOR) for imported Plasmodium falciparum malaria.

The diagnostic value of a polymerase chain reaction (PCR)-based method for amplifying a new target of repeated genes (STEVOR) in Plasmodium falciparum was prospectively assessed on samples from 210 febrile patients returning from areas endemic for malaria. This method is capable of detecting 0.01 parasites in one microliter of blood.

Strongyloides stercoralis infection in a non-immunosuppressed tourist with involvement of the central nervous system.

In the present case report a 50-year-old woman is presented with a Strongyloides stercoralis infection after a one-month stay in Sri Lanka. She showed a severe involvement of the central nervous system without a correlation of an immunosuppression. Strongyloides stercoralis is regarded as the cause of the cerebral involvement.

[Importance of Trichomonas tenax and Entamoeba gingivalis protozoa in the human oral cavity].

Trichomonas tenax and Entamoeba gingivalis are protozoa found in the human oral cavity. Morphological and ultrastructural characteristics of those parasites were reviewed and then studied with the scanning electron microscope in this paper. Based on previous epidemiological studies, the relationship between periodontal disease and those protozoa was analysed.

[Gel fractionation of immunoglobulins in the detection of specific antitoxoplasma IgM. Evaluation of a 1-year study].

Toxoplasmosis seroconversion is diagnosed on the presence of fluorescent antibodies. IgG level kinetics and presence of IgM at the Remington test are usually the points taken in consideration. But the Remington test can be false positive, or inadequate.

[Protozoa of the human oral cavity (epidemiological correlations and pathogenic possibilities].

The oral protozoa frequency has been studied in 300 patients consulting for oral problems. Entamoeba gingivalis has been isolated more frequently in culture than Trichomonas tenax (50.7% against 28%).

[Fasciola hepatica distomatosis in Maghreb. 2 new Algerian cases].

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.

[Coprologic diagnosis of amebiasis : the rectocolitis cell trap and the value of cultures].

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.

[Epidemiology of free-living amoebae in the waters of Strasbourg (France) (author's transl)].

164 strains of free-living amoebae were isolated from public drinking water supplies, swimming pools and official swimming ponds in Strasbourg; 11 genera and 16 species were identified. Some strains of Acanthamoeba are pathogenic for mice by intracerebral inoculation. Among the two strains of Naegleria found none is pathogenic.

[Study of free living amoebae in the waters of Strasbourg. Preliminary report (author's transl)].

75 strains of free living amoebae were isolated from public drinking water supplies, swimming pools and official swimming ponds in Strasbourg. 42 strains were identified till now. No pathogenic strain of Naegleria fowleri was found.
