Bacillary Necrosis in Pangasius
-
Garlic (Allium sativum) and Vietnamese balm (Elsholtzia ciliata) are well-known herbs that have been widely used in Vietnamese traditional medicines. However, studies on the effects of these plants in improving the immune system of fish have received less attention.

In this study, we isolated 28 strains of Bacillus spp. from water samples, catfish pond mud samples and earthworm manure (Perionyx excavates). By the cross-streak agar methods, 22 Bacillus strains showed the inhibition ability to Edwardsiella ictaluri, which caused Bacillary Necrosis Pangasius (BNP) in catfish (Pangasianodon hypophthalmus). Both Bacillus sp. Q16 and Q111 strains showed the highest inhibition to E. ictaluri by the double-layer agar methods.

Bacillary necrosis occurs very often in intensive farming of Tra catfish (Pangasius hypophthalmus) in the Mekong delta. Causative bacterium was identified as Edwardsiella ictaluri. Diseased fish with typical focal necrosis in the liver, kidney and spleen were sampled from 17 fish farms in Can Tho, Dong Thap, Vinh Long, An Giang and Ben Tre Province for bacterial isolation and identification. Among 97 isolates, 47 (48 %) were identified as E. ictaluri.
