HIV self-testing in adolescents living in Sub-Saharan Africa.

Less than 20% of African adolescents aged 10-19 years are aware of their HIV status, whereas HIV screening remains the gateway to care and while AIDS has become the leading cause of death among adolescents in Sub-Saharan Africa. According to the UNAIDS target, scalable HIV testing strategies specific to various age groups, populations, and geographical areas must be implemented to end the AIDS epidemic by 2030. Many African countries have implemented policies supporting HIV self-testing (HIVST). Evidence of practicability and efficiency of HIVST in Sub-Saharan Africa settings has been reported, including HIVST data among adolescents. Adapted strategies of HIVST are urgently needed to promote HIV testing among adolescents living in sub-Saharan Africa.

[Antibacterial activity of essential oils from mint in Senegal]. / Activité antibactérienne des huiles essentielles de menthes du Sénégal.

Three species of the Mentha gender are found in Senegal under the name of "Nana", and are essentially used in tea and juices as flavour. The aerial parts of the three species (common mint, mentholated mint and "fass" mint) have been harvested two months after they have been sown and the extraction of the essential oils was done by carrying them away with water vapour by hydrodistillation. The essential oils were used to study the antibacterial potency (typing of the Minimal Inhibitory concentrations-MIC) by the agar dilution method. This survey has been carried out on ten bacterial strains among which three (3) ATCC reference stubs, and on one fungus (Candida albicans). The MIC found was less than 25 mcg/ml; these results show an antibacterial potency according to the NCCLS norms (MIC < 256 mcg/ml). The tested strains were more sensitive to the essential oil of the "common mint" than the "fass mint". Pseudomonas aeruginosa was the most resistant strain and Candida albicans the most sensitive agent.
