[Serological survey for arbovirus antibodies in the human and simian populations of the South-East of Gabon (author's transl)].
A serological survey for arbovirus antibodies was carried out in human and simian populations of the South-East of Gabon. 197 human sera (adults), 34 simian sera (collected in the monkey colony of the Centre International de Recherches Médicales de Franceville) and 28 paired sera of mothers and their new-borns (samples collected from the umbilical cord) were tested using haemagglutination inhibition (HI) for all sera and complement fixation test (CF) for some of them. In the human population, 88% showed antibodies against yellow-fever virus as a consequence of vaccination, 20% against Chikungunya virus and 58% against Orungo virus. The high antibody titers for Chikungunya virus detected by HI test with CF antibodies proved a recent activity of this virus. The serological survey of simian population confirms the activity of Chikungunya virus in this area and demonstrates the circulation of one or more Flaviviruses, especially Zika virus. Transmission of maternal antibodies was established for the following arboviruses: Chikungunya, yellow-fever, Uganda S., Zika and Orungo.

[A serological survey of arboviruses in Gabon].
Serological studies for arbovirus antibodies were carried out on 1.279 human serum specimens collected from adults in south-eastern part of Gabon from June to September 1975 during a multipurpose epidemiological survey. More than 80% of the population surveyed have neutralizing antibodies for yellow fever virus as consequence of mass vaccination campaign. Chikungunya, Zika, Wesselsbron and Koutango virus showed some activity, especially in woodland savannahs.

[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.
