“…These species have several uniform and overlapping morphological characters, making the genus taxonomically difficult at the species level [12,20] and necessitating the study of additional parameters for the thorough characterization of taxa. The importance of the Indian species of Dipcadi resides not only in their endemism and narrow distribution but also in their phytochemical constituents [12,15,[21][22][23][24].…”

The genus Dipcadi Medik. (Subfamily: Scilloideae) has a narrow distribution in India and several overlapping morphological traits make the genus taxonomically challenging at the species level. Cytogenetic characterization can provide additional taxonomic data and can be used to evaluate genetic diversity at the species level. We have accomplished comparative karyotype analysis and fluorescence banding patterns using 4′-6-Diamidino-2-phenylindole (DAPI) and Chromomycin A3 (CMA) in five Indian species for the first time. The karyotypes of D. concanense and D. goaense exhibited similar fluorochrome banding profiles. However, D. montanum, D. ursulae and D. erythraeum differ distinctly in their karyotypes. In all taxa, CMA+ve/DAPI−ve or DAPI0 (GC-rich) constitutive heterochromatin was located at the constriction region or terminal satellite of the nucleolar chromosome. DAPI+ve/CMA−ve or CMA0 (AT-rich) heterochromatin dominates in D. montanum, D. ursulae and D. erythraeum. However, D. erythraeum shows a distinct variation in fluorochrome banding pattern from all other species. The distribution of CMA and DAPI bands is a reflection of heterochromatin composition and variations acquired by different species. This characterization can be used to assess phylogenetic relationships in the understudied genus Dipcadi and may serve as a basis for other genomic analyses and evolutionary studies.

“…Many of the diseases that affect the urban population are related in part to the use of domestic and industrial wastewater discharged in the community (Agossou et al, 2014). Such discharges are hazardous for the population due to their toxic effects (Agueh et al, 2015). In Chad, certain digestive infections are attributed rightly or wrongly to the consumption of market garden produces.…”

The phenomenon of antimicrobial resistance is a threat for public health. The aim of this study was firstly to assess the microbiological quality of fresh vegetables and fruits produced in the market gardens of N'Djamena-Chad; and secondly to study the antibiotic resistance profile of isolated strains. In order to achieve these objectives, data were collected through field surveys and the fresh fruits and vegetables harvested. The collected samples were microbiologically characterized using standardized methods. A total number of 180 fresh vegetables and fruits were analyzed. The results obtained on the prevalence of isolated pathogens showed a high microbial diversity (Aeromonas hydrophila, Aeromonas sobria, Escherichia coli, Salmonella spp., Staphylococcus aureus) and a high microbiological contamination of vegetables analysed. Lettuce was the most contaminated sample with about 46.7% of Escherichia coli and 7% Salmonella spp. However, contamination varied according to the site and was closely related to the poor quality of irrigation water. The study determined the biochemical characteristics of each isolate. The antibiotic sensitivity test of the isolates showed that the isolated pathogenic bacteria are all resistant to the antibiotics tested. A significant difference (p = 0.02) was observed between percentages mean of penicillin resistance (67%) and cephalosporins (29%). The consequences of this contamination are health risks for consumers and producers. Practical Applications Awareness on good farming practices for producers of vegetable and fruits is necessary to preserve consumers' health.
