To achieve this goal, two field trips were conducted in four towns endemic to Buruli ulcer in Côte d’Ivoire: Abidjan, Daloa, Tiassalé, and Yamoussoukro; one during the dry season and the other during the rainy season. Water was analyzed for the presence of the insertion sequence IS2404 using real-time PCR. Conventional PCR was then used to highlight MIRU/VNTR sequences. Following the analyses, six samples presented the MIRU 1 sequence during the dry season, with one copy found in three samples and two copies in another three. In contrast, during the rainy season, seven samples contained the MIRU 1 sequence, with two copies in one sample and three copies in two others. It is important to note that all samples were negative for the Locus 6 gene. This study highlights the significant impact of seasonal climatic conditions on the genetic composition of water samples and suggests a close correlation between genetic markers and mycobacterial contamination. These findings could have important public health and water resource management implications, as they provide additional information to understanding the risks associated with water contamination based on seasons. This seasonal approach to studying genetic markers in water samples opens new avenues for further research aimed at deepening our understanding of the dynamics of microbiological contaminants caused by mycobacteria in aquatic ecosystems.\u0000\u0000\u0000\u0000","PeriodicalId":490133,"journal":{"name":"European Journal of Aquatic Sciences","volume":" 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141828325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to analyse some water and sediment content parameters of inhabitant water bodies and investigate if there persists any correlation between physico-chemical parameters and fish assemblage. Freshwater ponds around Birbhum district, West Bengal (India) were selected for collection of water, sediment, and fish species samples. Temperature (°C), dissolved oxygen (DO), pH, nitrogen and phosphorous contents of water and sediment were analysed. Fish ecomorphological indices were calculated. The range of variations of the physico-chemical parameters in pond water were measured. For identifying the factors determining species assemblage, interaction effects of the factors throughout the seasons were first analysed. The analysis results of N and P contents from water and sediment showed no significant seasonal difference and correlation with assemblage. Next, fish species wise correlation of ecomorphological indices to temperature (T), dissolved oxygen (DO), total dissolved solid (TDS) and pH was analysed. Correlation analysis showed that temperature and pH had a moderate to strong correlation with most of the ecomorphological indices that determines the behaviour of SIFs as depicted by the indices. These two parameters could be considered as major direct parameters to understand the distribution of SIFs in water bodies.\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000","PeriodicalId":490133,"journal":{"name":"European Journal of Aquatic Sciences","volume":"17 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138968062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
