Description The effect of dietary supplementation of probiotic bacterium Bacillus licheniformis on
the histopathological changes in Macrobrachium rosenbergii juveniles (4.0 � 0.02 g)
challenged with known pathogenic strain of Vibrio alginolyticus are reported. Two
isocaloric basal diets supplemented with probiotic bacteria B. licheniformis
(1.0 9 109 cfu/g feed) and other without probiotic supplementation were fed to
the M. rosenbergii juveniles for 45 days. The histological observations revealed no
significant changes in the hepatopancreas and gut tissues of both the experimental
and the control groups which indicate that the present bacterium is a safe candidate
probiont for the host. Prawns were challenged with V. alginolyticus after 45 days of
feeding with probiotic diet. The histopathological studies of the hepatopancreas
revealed that M. rosenbergii fed with probiotic-supplemented diet showed less
changes as compared to the prawns fed with control diet on second and fourth day
of post-experimental challenge with V. alginolyticus. Histopathological observations
revealed that the gills of the prawns fed with control diet were severely affected in
comparison to the prawns fed with probiotic-supplemented diet after challenging
with V. alginolyticus. Results from this study revealed the improved protection
by dietary incorporation of B. licheniformis in reducing the histopathological
manifestations due to V. alginolyticus infection in freshwater prawn.
