Antibiotic sensitivity and pathogenicity of Aeromonas veronii isolated from diseased red hybrid tilapia in Malaysia

This article reports the antibiotics sensitivity and pathogenicity of Aeromonas veronii 5L isolated from diseased red hybrid tilapia. The antibiotic sensitivity of A. veronii 5L was determined towards 13 antimicrobial agents. Then, the bacterial inoculums ranging between 0 and 106 CFU/mL were used f...
