A comparative study of the number of taxa and fungal biomass consumed by the Pygmies and the Bantus of Gabon has been realized in two Gabon north regions (Ogooue-Ivindo and the Woleu-Ntem). This study has allowed not only to establish the list of consumed fungal sorts by those populations, but also to estimate the daily consumed fungal biomasses by each ethnical group. The study has revealed a significant difference between a numbers of taxa and the quantity of mushrooms consumed by various ethnical groups: the Pygmies of the area who live especially by hunting and fishing consumed 96% of the recorded taxa with some high mushrooms quantities (around 3 kg/day/family);the Bantus who live nearby Pygmies also consumed some high mushrooms quantities (around 2 kg/day/family) but a low taxa number (56% of taxa counted by the Fang;69% by the Kota;39% by the Kwele);on the other hand, the Bantus living nearest the Pygmies consumed a high taxa number as much as Pygmies (around 90% of taxa counted) but eat a lower mushrooms quantities than theirs distant congeners Pygmies (around 800 g/day/family).

Objective: To assess the performances of Cobas 6000 e601 and EVOLIS Bio Rad in the detection of HIV, HBV and HCV in blood donors in Libreville(Gabon).Methods: A cross-sectional investigation was conducted in July 2017 in a total of 2 000 blood donors recruited at the National Blood transfusion Center, Libreville Gabon.Among them, 363 donors were selected to compare the performances of COBAS 6000 e601(electro-chemiluminescence) and EVOLIS Bio Rad in detecting HIV, HBV and HCV using Cohen's kappa coefficient.Results: Both methods yielded similar results for the detection of HIV and HBs Ag. A very good agreement of 93.39% and an excellent agreement of 98.90% were obtained for the detection of HIV and Hbs Ag, with kappa values of 0.80 and 0.98, respectively. The observed agreement of 91.86% was found for the detection of HCV, which gave a fair agreement between the two methods with kappa = 0.33.Conclusions: The two evaluation methods showed a similar performance in the detection of HIV, HBV. However, given the high rate of intra and inter-genotypes recombination known for HIV and HBV, more robust techniques of detection such as polymerase chain reaction should be used to prevent post-transfusion contaminations.
