Context: The gut microbiota represents a complex ecosystem encompassing all unicellular microorganisms residing in the digestive tract, primarily bacteria, fungi, archaea, and even viruses. The relationship between the host and the microbiota is symbiotic: bacteria benefit from a stable environment, while the host gains numerous capabilities in terms of digestion, metabolism, nutrition, and immunity. However, numerous studies suggest that the gut microbiota plays a crucial role in various non-communicable diseases, including obesity, chronic inflammatory bowel diseases, allergic and immune disorders, behavioral disorders, and even certain cancers. The objective of our study was to characterize the gut microbiota of a group of breast cancer patients by comparing it to that of control subjects in Côte d’Ivoire, using a metagenomic approach. Method: A case-control study was conducted from May 2020 to September 2023. A total of 85 women (39 cases and 46 controls) were recruited, and stool samples were collected from both breast cancer patients and healthy women. Among these, ten (10) samples from patients and ten (10) samples from healthy women were randomly selected for the study of the gut microbiota. The gut microbiota was characterized by sequencing the V4 region of 16S rRNA using metagenomic NGS technology, and bioinformatic analysis was performed using the mothur pipeline. Results: In women with breast cancer, we observed a reduction in the relative abundance of the phyla Firmicutes and Bacteroidetes, as well as an increase in the phyla Actinobacteria and Verrucomicrobia. Additionally, their microbiota exhibited lower Chao1 and Sobs diversities compared to the control women (p < 0.05). Molecular variance analysis (AMOVA) revealed a significant difference between the case and control groups (p < 0.001). This study has highlighted a significant difference in the relative abundance of major phyla within the gut microbiota of cases compared to healthy controls. It wil

This article compliments the S18 session( transmission of traditional ecological knowledge and conservation of medicinal plants) at the 13th International Congress of Ethnobiology( ISE) in Montpellier,France( May2012). The aim of the article is to provide an insight into the livelihoods of a Berber community,a village of the High Atlas Mountains of Morocco,of the local biodiversity and most importantly,the prevalent use of medicinal plants for primary health care. It seeks to demonstrate the value of traditional ecological and herbal knowledge for the subsistence of the community and emphasises the vital role that family and community connections play for the transmission of traditional herbal knowledge within the community.

Sensorial information is very difficult to elicit, to represent and to manage because of its complexity. Fuzzy logic provides an interesting means to deal with such information, since it allows us to represent imprecise, vague or incomplete descriptions, which are very common in the management of subjective information. Aggregation methods proposed by fuzzy logic are further useful to combine the characteristics of the various components of sensorial information.
