An ethnobotanical study of antimalarial plants in Togo Maritime Region

BACKGROUND Malaria continues to be of great concern in Togo, as it accounts for high mortality rates, principally in children. Although plant-based medicines are the only means in major malarious regions of the country, still very little is known about the medicinal plants and medical practices of the indigenous people. OBJECTIVE The present study aimed to document the indigenous medicinal plant utilization for the management of malaria and related symptoms in Togo Maritime Region. METHODOLOGY Fifty Traditional Healers (TH) were selected with the help leaders of Togolese Traditional Healers Associations and information on their knowledge on the use of plants for malaria therapeutic purposes was gathered using a semi-structured interviews. RESULTS After enquiries, 52 plant species belonging to 49 genera and 29 families were recorded. The most represented families were Rubiaceae and Rutaceae with four species each. Traditional healers agreed more in the treatment of malaria (ICF=0.70), fever (ICF=0.33) and anemia (ICF=0.20). For the treatment of malaria, 38.46% (20/52) of the species cited in the study were of high fidelity level (FL=100%). The leaves (58.22%), leafy stem (33.78%) and fruits (8.52%) were the most used parts in concoctions. The main mode of preparation was decoction (69%) and the administration was essentially by oral route (79%) and body-bath (14%). CONCLUSION The issue of the study showed that Togo Maritime Region TH have a good knowledge of antimalarial plants. However the study must be extend to the whole country to lead to innovative strategies in malaria control. Such results could be a starting point for in vitro antimalarial screenings.

Sida acuta Burm. f.: a medicinal plant with numerous potencies

Sida acuta is shrub belonging to Malvaceae family. The plant is widely distributed in the subtropical regions where it is found in bushes, in farms and around habitations. Surveys conducted in indigenous places revealed that the plant had many traditional usages that varied from one region to another. The most cited illnesses are fever, headache and infections diseases. Indeed, many laboratory screening have been conducted to show the scientific rationale behind these usages and many compounds have been isolated from the plant. In the present review we listed the plant usages in folk medicine in some regions where the plant grows and we discussed on the confirmed in vitro activities after laboratory screenings. The review ended with the pharmacological properties of several compounds isolated from S. acuta principally alkaloids.

Contribution à la mise en place d’un système d’assurance qualité dans cinq laboratoires de bactériologie médicale au Togo

In Togo, as in many other developing countries, there is a lack of data on quality control and assurance of laboratories. The present study aimed to access for the quality management system in five medical bacteriology laboratories in Togo. The study was conducted from May to August 2006. Data were recorded by an audit on the reliability of results and the technical organization of laboratories. The standard ISO 15189:2003, the Togolese guide of good laboratory practices (GBEA-Togo) and the WHO medical bacteriology standards were used as references. The results of the audit showed a lack of culture media in laboratories, inappropriate choice of culture media, partial identification of some microorganisms, variability of identification procedures, a lack of diagnostic reagents and an inability to identify some potentially pathogenic bacteria. Concerning the technical organization of laboratories, compliance average ranging from 25.8 to 54.8 % was recorded. This indicates a limited organization of such laboratories. The issue of this study showed that laboratories must be equipped, their technical organization should be improved and they must establish a program of equipment maintenance.
