In the region where Banana tree Bacterial Wilt Disease has decimated banana tree plantations after many years, peasants who have only this culture as source of income co-op do not know what to do in order to cope with this continuing plague which lasts for more than a decade. Nevertheless with more or less resistant varieties including the FHIA-25 in the introduction, hope is allowed. However, in the process of planting plantations, regardless of fertilization and which our study has focused on the organic and mineral amendment, nothing can open on an issue to restore the banana fields around the huts in the agglomerated villages. Therefore, soil enrichment based on Tithonia, cow manure and ash is a way out among alternatives allowing farmers to resume the restoration of their banana plantation’s heritage. The results are promising in an endemic zone of banana wilt, sign of devastation, the respect of settlement with organic manure coupled with a versatile fertilizer produced with Tithonia and wooden ash, banana growing rapidly and the vigor of the plants presents an identical aspect to that under the natural conditions, with more performance on soils recognized as being too poor.

Milking as practiced in farms without devices ensuring hygienic measures in the highlands of Mulume-Munene in South Kivu drew our attention to study the hygienic quality of milk according to milking mode. Hand milking in most cases in an open kraal or barn is prone to many risks of microbial contamination. The results show that despite the existence of total coliforms, faecal coliforms, staphylococci and streptococci below the average threshold in gross value, especially less than 1x106 and 1x102 / CFU, there is no tuberculosis bacillus. Note that this milk is directly consumed fresh or marketed after processing into curd, That is "Mashanza".

The present work is a contribution to the study of the fight against enteric diseases by traditional therapeutics. It evaluates the effects of the aqueous extracts of Ephorbia hirta, Ipomea Involucrata, Mangifera indica, Musa ensete, Oxalis corymboza and Psidium goyaya and those of organic extracts based on methanol from the barks of Mangifera indica on strains of normal flora; E. coli and Enterobacter aerogenes and pathogenic strains of Salmonella typhi, Shigella flexneri and Shigella sonnei by the antibiogram test technique. The first tests with aqueous extracts for all plants provide valuable information on empirical recipe values. Some plants commonly used in the fight against diarrhea have an antibacterial effect. This is the case of Mangifera indica (barks and leaves), Musa ensete and Psidium goyava. These extracts also have in fact the strains of E. coli or Enterobacter aerogenes which represents a danger for the normal intestinal flora. Other plants, on the other hand, have no antibacterial effect or have a very reduced effect. Thus Oxalis corymboza and Ipomea involucrata appear to be involved in other antidiarrheal mechanisms. Euphobia hirta has a specific action on E. coli but it could be said that its antidysenteric role is specific to amoebiasis. Mangifera indica barks provide the most relevant extract, acting on all strains with the exception of Enterobacter aerogenes. The aqueous extracts based on methanol obtained after dilution give, during the tests, the MIC (Minimum Inhibitory Concentration) of a few mg / ml for Shigella sonnei (10-3 dilution) of a few tenth of mg / ml for Shigella flexneri and Salmonella typhi (dilution 10-4) and some one hundredth of mg / ml for E.coli (Dilution 10-5). The MIC for E. coli confirms the empirical recipes. The hypothesis that these barks are frequently used in cases of gastroenteritis in children is verified. The antibiogram tests carried out provide details on the empirical recipes and make it possible to affirm that the barks of Magnifera indica are effective against the gastroenteritis of children; the active ingredient is soluble in methanol, some plants present a danger for normal intestinal flora hence the need to associate vitamin B complex and that other plants have no antibacterial effect.
