Via Aminata.com, an interesting report: Dr. Cellou Balde persists and signs of the existence of the Ebola virus in Guinea since 1982. Excerpt from the Google translation:
The researcher at the Pasteur Institute Kindia, an author of the report on the Lassa virus in Guinea reaffirms that the Ebola virus in the country since 1982, Dr. Mamadou Cellou Balde said he was flexible to any scientific evidence that can refute the report. We deliver its third contribution he sent to our editor:
That diversion? Dear compatriots. Why as old as this one (32) Article is -there much controversy? Dear readers, an article is not contagious, it is for information only.
For those who have not seen this, that these references (you can download it): Bull.Soc.Path.Ex. 80 1987, 607-612. Title: CLINICAL RESEARCH ELEMENTS-EPIDEMIOLOGICAL AND LABORATORY IN GUINEA haemorrhagic fevers.
I add for the sake of argument a summary of the outcome as written in the article. "Elisa test results of 138 blood sera humans have revealed the presence of Ebola virus antibodies in 11 cases (8 0% of sera) with titers of 1: 8-1: 1 Four 024 blood sera with titles in Elisa 1 512, 1 512, 1 512 and 1: 1024 gave indirect immunofluorescence (IFI) titles: 1: 16, 1: 32, 1: 64 and 1: 64 respectively. This confirms the specificity of the results.
Treatment IIF blood sera of 79 convalescents has revealed 15 people with HIV (19%) vis-vis Ebola viruses with titers of 1: 32 to 1: 1024.
The review of 22 blood serum IFIs vis-à-vis the virus Lassa revealed three positive samples among the villagers of "Ouassou" with titers of 1: 16-1.: 32 Analysis of pools of bodies of 158 small rodents using the radioimmunoassay allowed to recognize the presence of antigens of Lassa virus in 4 trials, 3 positive pools were obtained from Mastomys natalensis and 4th from rodents of the genus Tatera .
The above data allow to assume that the Ebola virus has played a role in the etiology of acute febrile diseases observed retrospectively Madina Oula in people, which in the sera of antibodies to the virus have been detected."
