[Transmission of hepatitis B virus from mother to child in Bamako-Mali].

Results of a study about mother-infant transmission of hepatitis B virus (HBV) confirm the high degree of positivity of HBV markers in Bamako, Republic of Mali. Among 372 sera of mother-newborn pairs, seroprevalence of HBs Ag has been around 11% in mothers. The lack of anti HBc IgM in all sera agree probably with a relative old contamination. Pre-S2 epitope marker has been found in more than 70% of HBs Ag positive mothers and 50% of their children. Large discordance has been noted between the prevalence rate of this marker and the HBe Ag and viral DNA, other markers of HBV replication. Further studies are necessary for the clear understanding of HBV transmission systems in our country.

[Prevalence of hepatitis B virus in women of childbearing age in Mali].

A serological investigation on adult female in Mali show a high degree of positivity of hepatitis B virus (HBV) markers, of which 42% HBs Ag +. Only 6% exhibit active replication. The low prevalence of anti-HBs (+) with a high degree of anti-HB (+) explain a high incidence of infection with a low immune response to HBs antigen. The existence of anti-Delta (+) asymptomatic carriers is an additional support to a vaccination programme.

[Does Boutonneuse fever in France have equivalents outside the Mediterranean area?].

In western of France, outside of mediterranean spotted fever area, several sera from autochthonous patients were positive for the presence of anti-R. conori antibodies by indirect immunofluorescence test. What is it all about: authentic rickettsiosis or paraspecific seroreactions with other microorganisms? We discuss these hypothesis.

[Value and limits of serological methods: electrosyneresis and E.L.I.S.A. for the study of the prevalence of histoplasmosis in Mali].

The authors have looked for circulating antibodies on 168 subjects for the study of the prevalence of histoplasmosis in Mali. Two serologic systems were employed: with counter-immunoelectrophoresis precipitating bands were detected in 42% of sera, while 57% were positive with Enzyme-linked immunosorbent assay. E.L.I.S.A. appear less specific because many cross-reactions were observed with other diseases.

[Observation of Schistosoma mansoni by scanning electron microscopy].

The integumental surface of adult Schistosoma mansoni was studied by scanning electron microscopy (SEM) at 220 to 10,000 magnifications. SEM shows certain basic features such as spines in the oral sucker and the acetabulum which may facilitate rasping and attachment of the parasite to stay in the bloodstream of the definitive host. It seems likely that SEM visualization will be a means for differentiation some species of the genus Schistosoma.

[Does human distomiasis due to Fasiola gigantica exist in the delta of the Niger river in Mali? (apropos of a serological survey)].

Finding of specific anti-Fasciola antibodies in persons living in the central area of the delta of Niger shows that human fascioliasis is a reality in Mali. Fasciola gigantica, the single species affecting livestock is probably the parasite concerned. We think that this parasitic disease in humans is underestimated, obscured by schistosomiasis which is hyperendemic in the country. Complementary studies are much needed for better identification of the problem.

[Autochthonous amebiasis in the region of Nantes].

A retrospective study on amoebiasis observed in the central hospital in Nantes since twenty years, shows that, at least, 16 % of the intestinal cases and 1/6, 5 of 30 cases of hepatic amoebiasis are autochthonous.
