This study was aimed at evaluating the water quality profile of Ekenwan River located in Edo-South, Nigeria and also to determine the antibiotics sensitivity pattern of its isolated bacteria. Water samples were collected from upstream and downstream stations of the river and they were designated as station A and station B respectively; standard analytical and bacteriological procedures were adopted. The pH of water samples for station A ranged from 5.11-5.86 while and station B ranged from 4.11-5.94.

In this study, Bacillus subtilis isolated from decaying pineapple fruit peel was identified by both phenotypic and molecular techniques and employed for the production of single cell protein from three agricultural wastes: melon, groundnut and walnut shells. Chemical analysis showed these agro-wastes to contain high amounts of carbohydrate which ranged from 61.26 - 65.12 %. Using submerged fermentation, maximum yield of cell biomass was produced from the groundnut shell followed by melon shell as substrate for fermentation.

Ethanolic root extract of Anacardium occidentale L. was evaluated for antimicrobial activities against selected clinical isolates. Bacteria and fungi pathogens obtained from the laboratory unit of a functional health facility for this study included Escherichia coli, Kblesiella pneumoniae, Staphylococcus aureus, Pseudomonas aeruginosa, Proteus vulgaris, Streptococcus sp., Candida albicans and Aspergillus niger. The identities of the bacteria spp. were re-established following standard physical and biochemical routines.

 The use of antibiotics in animal husbandry has helped in the reduction of animal diseases. However, health workers as well as enlightened consumers are becoming more concerned with the health implications such as resistance associated with the use of antibiotics since the same group of antibiotics are used in human medicine.Sixty (60) samples from pork meat, piggery environment and abbatoir effluent were screened for the presence of bacteria by selective and differential cultural procedures. Susceptibility of isolates to antibiotics and plasmid
