Protective Effects of Bacteriophages against Aeromonas hydrophila Species Causing Motile Aeromonas Septicemia (MAS) in Striped Catfish.

To determine the effectivity of bacteriophages in controlling the mass mortality of striped catfish () due to infections caused by spp. in Vietnamese fish farms, bacteriophages against pathogenic were isolated. -phage 2 and -phage 5 were successfully isolated from water samples from the Saigon River of Ho Chi Minh City, Vietnam.

Biomass accumulation of Panax vietnamensis in cell suspension cultures varies with addition of plant growth regulators and organic additives.

Objective: To evaluate the impact of plant growth regulators including kinetin (KN), benzyl adenine and naphthalene acetic acid, yeast extract and casein hydrolyzate on biomass accumulation of Vietnamese ginseng Panax vietnamensis (P. vietnamensis) in cell suspension culture.

Methods: Cell suspension cultures were established from friable calluses derived from leaves and petioles of 3-year-old in-vitro P.
