Rotavirus prevalence and relationships with climatological factors in Gabon, Africa.

A one-year study of rotavirus prevalence was carried out using electron microscopy in Gabon, equatorial Africa. One hundred fifty-six nonhospitalized diarrheic children up to 10 years of age and 115 age-matched controls were investigated together with diarrheic adults and children over 10 years of age. Rotaviruses were observed only in diarrheic children under 10 years of age (10.2%). Rotaviruses were more prevalent in the dry-season months (19.2% versus 1.3%, P less than .001). Rotaviruses were the most commonly found among all the viral, bacterial, and parasitic agents we detected, with the exception of the coronaviruslike particles, which are the subject of another paper [Sitbon, 1985].

Loa loa: a simple method for isolation of microfilariae from blood with production of antigen in extraction medium.

A simple method for isolating Loa loa microfilariae from the blood of patients is described. This involves sedimentation on Ficoll followed by migration of the microfilariae into an extraction medium. During migration the microfilariae release antigen-rich excretory or secretory products. The procedure thus yields two products: pure microfilariae and large amounts of antigen in the extraction medium.

[Etiological study of low fertility in eastern Gaboon. III. Filarial endemicity (Loa loa, D. perstans). Prevalence of microfilariae in hydroceles (author's transl)].

During an inquiry performed in Gaboon the prevalence of hydroceles had led to puncture systematically every vaginal flow. 68 fluids were so collected at the end of the inquiry. Subsequently the statistical analysis of the results in men seems to suggest a correlation between microfilaremia (Loa loa and D. perstans) and the prevalence of hydroceles. Microfilariae were found in 77% according to the following distribution: Loa loa seldom diagnosed in this kind of flow were detected in 10%; D. perstans although never reported so far in hydrocele fluids appeared to be present in 62%. O. volvulus more currently referred to in hydrocele liquids were scarcely traced.

[Apropos of a case of myospherulosis].

The case was one of a 25-year-old woman with a polycystic subcutaneous nodule in the posterior iliac region, developing three weeks after a series of injections. Histological examination revealed the presence of cysts with a saccular formation filled with endospherules characteristic of the disorder. Myospherulosis is reviewed in the light of this first european case.

[Toxoplasmosis in Eastern Gabon. Results of a serologic survey].

1,448 sera taken from individuals of various places of South-Eastern Gabon have been studied by means of indirect immunofluorescence and Fulton direct agglutination associated with 2-mercapto-ethanol test, 52.6% contained antitoxiplasmic antibodies. This study showed that toxoplasmic infection occurs early in both sexes, that it is more frequent in men (57.9%) than in women (45.4%), that the Ogooué-Lolo province is more contaminated (62.6%) than the High Ogooué province (49.6%). It seems that prevalence differences are less dependent upon the telluric elimate than upon other factors, which remain to find.

[Intestinal parasitism in eastern Gabon].

A survey of 1,548 stools samples carried out in Gabon showed in the adult population a parasitism ratio of about 100%. Among the protozoa, D. fragilis was found in 0.3% of the cases. In contradiction with the usual observations in tropical Africa, A. lumbricoides and T. trichiura infestation is very high in the villages. The demonstration of S. intercalatum in almost every place of the survey and an important focus at Okondja proves the extension of this bilharziosis.
