Background:In Togo, malaria constitutes a major public health problem but, until now, the population still mostly relies on herbal medicine for healing. This study aimed to document medicinal plants used for malaria therapy in the Plateau region of the country.Methodology:Semi-structured questionnaire interviews were used to gather ethnobotanical and sociodemographic data from traditional healers of the study area.Results:A total of 61 plants species belonging to 33 families were found to be in use for malaria therapy in the Plateau region. Caesalpiniaceae were the most represented family with 7 species, followed by Euphorbiaceae and Poaceae with 4 species each. According to the relative frequency of citation (RFC), Newbouldia laevis Seem. (RFC =0.52), Sarcocephalus latifolius (Sm.) E.A. Bruce (RFC =0.48), Acanthospermum hispidum DC. (RFC =0.43), and Senna siamea (Lam.) H.S. Irwin and Barneby (RFC =0.40) were the most cited in the treatment of malaria in the traditional medicine in the Plateau region. The parts of plants used could either be the barks, roots, leaves, or whole plants. The recipes also could be a combination of various species of plants or plant parts.Conclusion:This study highlights the potential sources for the development of new antimalarial drugs from indigenous medicinal plants found in the Plateau region of Togo. Such results could be a starting point for in vitro antimalarial screenings.SUMMARY 61 plants species from 33 families are use for malaria therapy in the Plateau region of TogoThe main families are Caesalpiniaceae Euphorbiaceae and PoaceaeThe most used species are Newbouldia laevis Seem.

IntroductionLes plantes constituent une grande source de principes actifs qui peuvent être utilisés pour traiter de nombreuses maladies, dont le diabète. L'objectif de cette étude était de recenser les plantes utilisées en médecine traditionnelle pour traiter le diabète dans la région Maritime du Togo.MéthodesDe janvier 2013 à juin 2014, une enquête ethnobotanique a été réalisée auprès de 164 guérisseurs traditionnels dans la région Maritime par des interviews directes à l'aide d'un questionnaire semi structuré.RésultatsLes données recueillies ont permis d'identifier 112 espèces végétales appartenant à 51 familles. Les familles les plus représentées ont été les Caesalpiniaceae / Fabaceae avec 9 espèces, suivie des Euphorbiaceae et des Compositae avec 8 espèces chacune. Les espèces les plus citées ont été Allium sativum, Alium cepa, Guilandina bonduc, Moringa oleifera et de Picralima nitida qui ont eu une valeur usuelle de 0,05. En termes de recettes, 132 recettes sont préparées à partir des 112 espèces de plantes. Les recettes à plantes uniques ont été au nombre de 78, tandis que 54 recettes sont obtenues par des associations de plantes. Les parties de plantes les plus utilisées ont été les feuilles suivies par les racines. La principale méthode de préparation reste la décoction.ConclusionLa région maritime du Togo dispose d'une biodiversité floristique importante en matière de plantes antidiabétiques. Ces résultats constituent une bonne base de données pour le criblage biologique dans la recherche de molécules antidiabétiques à base des plantes.

and recipes included in the herbal medicines in the maritime region where this disease is more common. Method: The methodology was based on ethnobotanical semi-structural individual interviews of 16 traditional healers in the maritime region. The Data were collected and analyzed in Microsoft excel 2013. Results: 10 of the traditional healers were male and the average age of all the respondents was 42.31 ± 4.24 years. A total of 27 plant species belonging to 20 families were identified. The most represented families were: Caesalpinaceae with 3 species, Euphorbiaceae, Apocynaceae, Asteraceae, Sapindaceae and Annonaceae with 2 species each. In the preparation methods, the decoction is the most used (37%), followed by the black powdered incorporated in an ointment (24%), the maceration (15%), the infusion (12%), the spraying (6%) and poultices (6%). These modes of preparation, were administered mainly externally by massage, disinfection of the lesion and orally. The most used parts of the plants were leaves (48%), roots (21%), and bark (10%). The species with the highest frequency of use were Blighia sapida KD Koenig, Amaranthus spinosus L, Ocimum canum Sims, Piliostigma thonningii (Schum.) Milne-Redh, Aloe verra L, Anacardium occidentale L, Paullinia pinnata L and Xylopia aethiopica (Dunal) A.Rich. Conclusion: By highlighting these plant species of interest, this study has an applicability in therapeutic innovation. It can contribute to the chemical, pharmacological and clinical evaluations of their molecules leading to development of phytomedicines to produce new drugs to strengthen the already existing therapeutic arsenal.

Background: Buruli ulcer is the third most common mycobacterial disease worldwide. Cases most occur in 30 countries but severe cases occur in West Africa countries such as Benin, Cote d’Ivoire and Togo mainly in rural regions. Early diagnosis may prevent severe disability. The molecular technique seems the best solution and new Mycobacterial Interspersed Repetitive Units (MIRU) and variable number tandem repeats (VNTR) typing method are themost reproducible in this regard. They propose geographical, inter and intraspecies differentiation and can be used as a diagnosis tool. Objective: The objective of this study was to investigate the molecular diversity by using MIRUVNTR typing in clinical samples of BU patients in Togo. Study Design: 64 DNA extracts from clinical samples were collected from BU patients in the two principal endemics districts in Togo (Yoto and Zio) with three less endemic districts (Bas Mono, Lacs and Vo). First, IS2404 and KR real-time PCR plus IS2606 conventional PCR were performed. In a second step, the strains were analysed by PCR typing for five specific and sensitive markers MIRU1, VNTR6, ST1, VNTR19 and VNTR9. Results and Conclusion: 71.11% were positive for IS2404, 3.13% were positives for PCR-KR and 31.11% for IS 2606. By MIRU-VNTR typing, 48.86% positive result was found for MIRU1 and 25.00%, 20.31%, 18.75% and 14.06% for VNTR6, ST1, VNTR19 and VNTR9 respectively. One of the samples was negative for all genotyping markers. Two different genetic profiles were identified by MIRU1, ST1 and VNTR loci by gel-analysed of the amplified products. The VNTR profile B (3,1,1,2) corresponding of 3 copies MIRU1, 1 copy VNTR6, 1 copy ST-1 and two copies of VNTR19 was detected in 15.63% of samples and the VNTR profile A (1,1,1,2) corresponding of 1 copy MIRU1, 1 copy VNTR6, 1 copy ST-1 and 2 copies of VNTR19 was detected in 3.13% of samples and confirms the West African genotype (3,1,1) in Togo. Different genetic strains of Mycobacterium ulcerans (M. ulcerans) were co-circulated in the same endemic region in the country. This study has described first the circulating of different genetic strains of M. ulcerans in Togo.
