Microbiological Quality Assessment and Antibiogram of the Bacteria Isolated from Fish Feed, Oyo, South-West Nigeria
Journal Title: Journal of Animal Science Advances - Year 2015, Vol 5, Issue 3
Abstract
Essential nutrient is required for the growth of aquaculture either in the wild or in the artificial environment. Therefore, artificial feed need to contain essential nutrients and free of pathogenic microorganism. Samples of both imported and local fish feed samples were collected and presence of microorganisms was examined using bacteriological media. Morphological and Biochemical identification of the isolates were carried out. Also, antibiotic susceptibility patterns of the bacteria isolated were carried out using Gram negative and positive specific antibiotics (Oxoid) with reference to zones of inhibition observed from the plates. It was observed that fish feed samples possess pH and moisture content ranges from 6.8 to 7.0 and 10% to 17% respectively. The proportion of microorganisms obtained from the sample shows Bacillus sp 33%, Staphylococcus sp 13%, Streptococcus sp 13%, Pseudomonas sp 7%, Klebsiella sp 7% and Proteus sp 6%. Antimicrobial susceptibility was tested and interpreted using NCCLS, 2006. Regulatory authorities on animal (fish) feed should therefore endeavor to ensure pathogen-free animal (fish) feed. This will ensure good and healthy meat or food (fish) production for human population.
