Article
Full-text available
The nonstructural protein 4A (NS4A) of flaviviruses has been implicated as a "central organizer" of the membrane-bound replication complex during virus replication. However, its role in the host responses to virus infection is not understood. Using the yeast-two-hybrid library screen, we identified a multitude of host proteins interacting with the...

The Dengue virus (DENV) and Chikungunya virus (CHIKV) are the arboviruses that pose a threat to global public health. Coinfection and antibody-dependent enhancement are major areas of concern during DENV and CHIKV infections, which can alter the clinical severity. Acute hepatic illness is a common manifestation and major sign of disease severity up...
Article
Co-infections in fish by the wide array of pathogens have been little researched, although such infections are commonly noticed in nature. A murrel farm recorded 100% mortality in adults of Channa striata within 3-4 days of infection during winter. The clinical signs included cloudy eyes, excess mucus secretion, haemorrhages on the body, lethargy a...
Preprint
Full-text available
Infectious spleen and kidney necrosis virus (ISKNV), a type species of the genus Megalocytivirus, poses a threat to ornamental fish trade as most cases show nonspecific symptoms, thus making timely diagnosis challenging. Apparently health molly (Poecilia sphenops) and angelfish (Pterophyllum scalare) collected from two distinct geographic localitie...
Article
Most environmental parameters have no consistent effect on the expression of bacterial genes responsible for their virulence. However, as fish are poikilothermic, the possibility of temperature variation having a pronounced effect on the expression of virulence-associated gene(s) of bacteria infecting the host needs to be investigated. In this stud...
Article
During the period 2014-18, a total of 219 cases of fish mortalities were being investigated under a passive surveillance programme. Among different disease incidences parasitic diseases were found to the major contributor accounting for 74.88% cases followed by bacterial diseases of 12.79%, mixed bacterial and parasitic diseases of 10.50% and viral...
Article
Koi sleepy disease caused by carp edema virus (CEV) of pox virus is a potential carp killer and poses a constant threat to co-cultured fish. Only limited studies are available on its occurrence from the eastern part of India. Here, we report a large-scale mortality of koi carps (Cyprinus carpio koi) in ornamental fish farm of Choudwar, Cuttack, Odi...
Article
Piscine nodavirus is the causative agent of viral encephalopathy and retinopathy in marine and freshwater fish worldwide. The present investigation was carried out to know the persistence and diversity of betanodavirus in wild healthy seabass seeds around east and west coasts of India from three major landing sites. The seeds obtained from two coas...
Article
Full-text available
Demand and production of freshwater pearl mussel Lamellidens marginalis (Lamarck, 1819) have increased many folds in the last few decades. There are only very scanty reports of infective agents and their pathogenicity affecting this particular mussel species. Heavy infestation and mortality of L. marginalis were observed in the ponds of Freshwater...
Conference Paper
Global aquaculture production of Channa striata has increased from 480 tons in 1950 to 17847 tons in 2014 and it is expected to be the species of interest in aquaculture in near future. The process of intensification of its culture practices has led to emergence or appearance of many diseases in stressful conditions, thus leading to large scale mor...
Article
Full-text available
Systomus sarana (Hamilton, 1822) (weight; 370 g; length: 29.0 cm ) obtained from a carp polyculture pond revealed presence of a solid nodular tumorous mass on right dorso-lateral side of the body. Surgical excision and further histopathological examination of the focal non-invasive mass revealed that the tumor is a fibroma covered by thick stratifi...
Article
This outbreak report details of a mortality event where cyprinid herpes virus-2 (CyHV-2) was detected in association with multidrug-resistant Aeromonas hydrophila infection in goldfish, Carassius auratus, from commercial farms. The goldfish exhibited large scale hemorrhages on the body, fins and gills, lepidorthosis, necrosed gills, protruded anus...
