Diversity of Bacteria Contaminants in Tissues of Fish Cultured in Organic Waste-Fertilized Ponds: Health Implications
Bacterial populations contaminating various tissues of fish cultured in fish ponds fertilized with different organic wastes have been studied. Twenty-five genera of bacteria were identified as associated with the fish tissues. The identified bacteria included one genus of spiral and curved bacteria, one genus of Gram-negative aerobic rod, sixteen genera of Gram-negative facultative anaerobic ro...
