[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.
