Abstract:To effectively control the economic loss caused by infection of Aeromonas hydrophila from channel catfish Ictalurus punctatus, 41 kinds of extracts of Chinese herbal medicine were obtained by decoction, such as Flos Lonicerae, Spica Prunellae and Pericarpium Granati. The diameter of inhibition circle, the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of 41 kinds of Chinese herbal medicine and their compound to A. hydrophila were detected respectively. The results showed that 14 of 41 Chinese herbs had bacteriostasis circle, with the minimal MIC in Rhizoma Coptidis at concentration of 7.81 mg/mL, comprehensive diameter of inhibition circle, MIC and MBC, comprehensive screening of 6 Chinese herbs with better bacteriostatic effect: Pericarpium Granati, Fructus Chebulae, Herba Violae, Lignum Sappan, Rhizoma Coptidis and Fructus Mume. Drug combination results showed that there was no antagonism of 93.3% between the 6 herbs, with positive effect of 80%. The results of 25 groups according to preparation tables of mixed Chinese herbal medicine showed that M-10 compound group with V (Pericarpium Granati)∶V (Fructus Chebulae)∶V (Herba Violae)∶V (Lignum Sappan)∶V (Rhizoma Coptidis)∶V (Fructus Mume) = 2∶5∶1∶2∶3∶4 had the best comprehensive bacteriostatic effect. The findings provide a theoretical basis for the application of Chinese herbal medicine in bacterial diseases of A. hydrophila.
