Co-infection of Lactococcus garvieae and Aeromonas hydrophila in cultured Nile Tilapia in Kerala, India.

Co-infection of Lactococcus garvieae and Aeromonas hydrophila, has been confirmed from diseased Nile Tilapia (Oreochromis niloticus), Chithralada strain cultured in a freshwater rearing pond of Alappuzha district of Kerala, India. The aetiological agents behind the disease outbreak were bacteriologically proven and confirmed by 16SrRNA sequencing and phylogenetic analysis. PCR detection of the virulent genes, showed existence of adhesin and hemolysin in L.

Development of recombinant major capsid protein Vaccine and assessment of its efficacy against SRDV in similar damselfish (Pomacentrus similis).

Viral vaccines against emerging viral diseases are crucial for encouraging successful aquaculture production. In this research, an experimental recombinant major capsid protein vaccine of similar damselfish virus was prepared and examined for its efficacy in marine ornamental fish, similar damselfish (Pomacentrus similis). The MCP gene of the SRDV was amplified from the viral DNA by a specific primer set viz bamHI and XhoI- restriction sites and confirmed by agarose gel electrophoresis with a target size of 1416 bp.

Three Draft Genome Sequences of White Spot Syndrome Virus from India.

White spot syndrome virus (WSSV) is a pathogen causing significant economic losses to shrimp aquaculture worldwide. Previously, five genome sequences of the virus from farmed shrimp (Penaeus vannamei and Penaeus monodon) in India were reported, all originating from farms located on the east coast of the country. Here, we report three new and distinct WSSV genome sequences, two from shrimp () farmed on the west coast of India and the third from the east coast.

Molecular variations in Vibrio alginolyticus and V. harveyi in shrimp-farming systems upon stress.

A study was performed to investigate the genomic variations in the shrimp farm isolates of Vibrio alginolyticus and V. harveyi when the isolates were subjected to environmental stress. Samples of shrimps, water and sediment were collected from Southern Indian coastal shrimp farms.
