White gut Disease and White Muscle Disease Care
INDICATIONS:WHITE GUT DISEASE
The epizootic of WMD was first recorded in November 2001 in few hatchery reared PL of M. rosenbergii in Andrapradesh and Tamilnadu states. More than 18 cases of WMD in freshwater prawn hatcheries with PL mortalities ranging from 30% to 100% were recorded from November 2001 to December 2002. The first sign related to this disease was the poor feeding (mineral deficiency in water, poor quality feed) and lethargy of the prawns especially during the first 5 days of PL settlement resulting in slow mortality
As the morphological and clinical signs of the disease reported by Chen et al. (2001) were similar to the WMD recorded in this study. It is likely that the involvement of the Gram-positive cocci, Lactococcus garvieae in WMD found by those workers could possibly have been a secondary infection. The disease progressively destroyed the abdominal muscular organization of the prawns especially the striated muscles finally leading to mortality. Several authors reported white muscle disease in shrimps and prawns (Chen et al., 1992; Sudhakaran et al, 2006; Ravi et al., 2009). Besides the above, this white muscle disease also recorded in L. vannamei .
Histopathological examination of the infected animals revealed highly necrotic musculature. Degenerated muscle areas showed aggregations of melanized nuclei, many of which looked like inclusion bodies. Bacteriological examination of affected PL showed the presence of Staphylococcus spp. as a predominant organism.
Affected PL showed characteristic whitening of abdominal musculature associated with anorexia and lethargy. The moribund PL seriously affected with WMD appeared milky white and the mortalities in hatcheries were reported to be 30-100%
Surveys undertaken on diseases caused by Vibrio spp. in Penaeus monodon from culture ponds of coastal Andhra Pradesh recorded the occurrence of five types of diseases: Tail necrosis, shell disease, red disease, loose shell syndrome (LSS), and white gut disease (WGD).
Among these, LSS, WGD, and red disease caused mass mortalities in shrimp culture ponds. Six species of Vibrio—V. harveyi, V. parahaemolyticus, V. alginolyticus, V. anguillarum, V. vulnificus, and V. splendidus—are associated with the diseased shrimp.
The number of Vibrio spp. associated with each disease ranged from two to five. Additionally, shrimp with red disease had concurrent infections with white spot syndrome virus.
Vibrio harveyi in the case of LSS and WGD, V. parahaemolyticus in the case of red disease, and V. alginolyticus in the case of shell disease are the major etiologcal agents.
Differences occur in the degree of virulence of different species of Vibrio and also different isolates of the same species. Vibrio harveyi isolated from LSS shrimp is the most virulent. In general, all the Vibrio isolates from LSS shrimp tend to be more virulent as compared to their counterparts from other diseased shrimp.
It is apparent that the degree of virulence of various Vibrio isolates depends on its source and the pond environmental conditions.
The luminous V. harveyi exhibited resistance to many antibiotics and susceptibility to only three drugs. Considering the emergence of antimicrobial resistant strains of Vibrio, the need for using probiotics in place of antibiotics for disease control is stressed
1) Assists in activating the function of Hepato pancrease
2) Aids to control white gut disease in shrimps
3) Helps in achieving faster growth rate and faster body weight gain.
