Anti-Ulcerative Property of Bacillus subtilis against Vibrio harveyi

Fishes are important part of the marine environment and there are some bacterial pathogens which affect the fish population in greater number. Among all the bacterial pathogens, Vibrio harveyi is mainly associated with the fish species reared in farms. Vibrio harveyi causes ulcerative disorders in the fish population which are reared in farms. They also cause ulcers in other aquatic habitats like shrimp, lobster, seahorses, sharks and seabass in more numbers. In a particular period of time, the pathogenicity rapidly spreads at a greater rate and its pathogenicity is determined by its cell concentration. Diseases like luminous vibrosis, eye lesions, vasculitis and gastro-enteritis is caused by this deadly bacterial pathogen in recent years. Various symptoms like eye opacity, infections in fin rot and tail, lesions in muscle, ulcers in skin or mouth, anorexia, swollen intestine and whole fish darkening occur in the infected fish due to Vibrio harveyi. Considering the above facts in view, this book provides a comprehensive information on the antiulcerative property of Bacillus subtilis against Vibrio harveyi, a bacterial pathogen of Labeo rohita (Rohu Fish).
