Aims: Therefore, the aim of this study was to identify fungal organisms associated with Anthracnose disease of mango in Yola, Adamawa state, Northeastern Nigeria and to test their pathogenicity. Study Design: Laboratory based controlled experiment. Methodology: Naturally anthracnose infected mango fruits and leaves were purposely sampled from different home gardens, farms, and markets in Yola. The symptomatic plant parts were immediately taken to the laboratory for direct isolation, characterization, identification and pathogenicity testing of fungal isolates. Results: A total of 19 fungal colonies were obtained from the anthracnose infected mango fruits and leaves. Based on similarity of morphological features (colony colour, texture presence of septate mycelia or not, spore shape and number of septa), fungal colonies were grouped into 3 species and were identified as Colletotrichum gloeosporio...

Study Design: The use of In-Silico studies for the structural annotation of Methylthioadenosine Nucleosidase protein. Place and Duration of Study: The research was conducted at the Bioinformatics Laboratory, Chevron Biotechnology Centre, Modibbo Adama University of Yola, Nigeria. Between June 2018 to July 2018. Methodology: The Methylthioadenosine Nucleosidase protein was retrieved from NCBI, physical and chemical parameters were calculated using ExPASy - ProtParam tool, the server SOPMA was used for secondary structure analysis (helix, sheets, and coils) and I-TASSER was used to obtain the 3D structure. Results: ExPASy - Prot Param tool computated the various physical and chemical parameters such as molecular weight (MW) 30117.97, total number of positively (+...

This study was undertaken to evaluate the phytochemical composition, mineral composition, nutritional value and antimicrobial activity of Senna occidentalis ethanolic leaf extracts. The phytochemical investigation revealed the presence of alkaloids, saponins, tanins, terpenoids, sterols, and cardiac glycosides. The elemental analysis of Senna occidentalis revealed the presence of Calcium (68.9525 mg/L), Copper (0.2325 mg/L), Magnesium (1.1092 mg/L), Zinc (0.5969 mg/L), Sodium (18.5191 mg/L), Iron (5.8078 mg/L) and Potassium (202.0501 mg/L) respectively. Results also showed that extract of Senna occidentalis leaves were most active with inhibitory activity between 16-34mm against tested microorganisms (Escherichia coli, Staphylococcus aerus, Psuedomonas sp, Klebsciella pneumonia, and Salmonella thypi) at 1000, 500 and 250 mg/ml concentrations using 0.25 mg/ml ampicillin as the positive control. Proximate analysis revealed moisture content of 12.5%, ash 13.8%, crude protein 13.1%, crude fiber 11.3%, fat 3.8% and carbohydrate content of 45.5%. These values suggest that the leaves of Senna occidentalis can be consumed as either a nutrient supplement or as a source of micro and macro elements to the body, in addition to its usefulness towards the treatment of different microbial infections.
