K. K. Vijayan,I. S. Bright Singh,N. S. Jayaprakash,Shankar Vinayakarao Alavandi,S. Somnath Pai,R. Preetha,J.J.S. Rajan,T.C. Santiago +7 more
TL;DR: The results of this study indicated that the organism Pseudomonas sp PS 102 could be employed as a potential probiont in shrimp and prawn aquaculture systems for management and control of bacterial infections.
Journal ArticleDOI
Emergence of Enterocytozoon hepatopenaei (EHP) in farmed Penaeus (Litopenaeus) vannamei in India
K.V. Rajendran,Saloni Shivam,P. Ezhil Praveena,J.J.S. Rajan,T. Sathish Kumar,Satheesha Avunje,V. Jagadeesan,S.V.A.N.V. Prasad Babu,Ashish Pande,A. Navaneeth Krishnan,Shankar Vinayakarao Alavandi,Koyadan Kizhakedath Vijayan +11 more
TL;DR: Although EHP could be detected from slow-growing as well as WFS-affected animals, the present study could not conclusively elucidate the association of EHP with these clinical signs through experimental infection trials.
Journal ArticleDOI

I.S. Azad,M. S. Shekhar,A. R. Thirunavukkarasu,M. Poornima,M. Kailasam,J.J.S. Rajan,S.A. Ali,Mathew Abraham,P. Ravichandran +8 more
TL;DR: The clinical manifestations, pathology and electron microscopy observations supported by the RT-PCR analysis suggest that the nerve necrosis was due to nodavirus infection in the larvae of the Asian sea bass Lates calcarifer, the first report of piscine nodav virus infection from the Indian sub-continent.
Journal ArticleDOI
Evaluation of Pseudomonas sp. PM 11 and Vibrio fluvialis PM 17 on immune indices of tiger shrimp, Penaeus monodon.
