Alavandi. S. V. Dr
Designation : Principal Scientist & Head, AAHED
Discipline : Microbiology (Animal Sciences)
Division : Aquatic Animal Health and Environment Division
Specialization : Microbiology (Animal Sciences)
Research areas:
  • Dr. Alavandi has interest in understanding the causes of diseases currently plaguing shrimp aquaculture such as running mortality syndrome (RMS), white gut / white faeces syndrome, growth retardation / variation and white muscle syndrome using conventional tools, culture-independent tools, metagenomics and next-gen-sequencing (NGS) approaches in addition to exploring involvement of known pathogens and the role of environment.He is also interested in developing rapid diagnostics for important pathogens affecting aquaculture.
  • His quest also lies in demonstrating the virulence mechanism of certain strains of Vibrio parahaemolyticus and V. harveyi considered to be significant pathogens of penaeid shrimp.He is exploring the secretion systems, effector proteins and the role of bacteriophages in the virulence mechanism of these bacteria.
  • Biocontrol of diseases of shrimp is another important area of his work.Microbial, algal and plant biomolecules and antagonistic bacteria are being explored for antiviral potential targeting the most devastating shrimp white spot syndrome virus.His lab has a large collection of bacteriophages against V.harveyi,responsible for luminescent bacterial diseaseof larval shrimp in hatcheries andhe is evaluating bacteriophage therapy for biocontrol of luminescent bacterial disease in shrimp hatcheries.
Brief profile:

Dr. Alavandi is currently heading the Aquatic Animal Health and Environment Division (AAHED) and leading the research programme on surveillance of diseases with special reference to emerging issuesin brackishwater aquaculture.He has been providingexpert technical services for aquatic animal quarantine and on several technical aspects to the Department of Animal Husbandry Dairying and Fisheries, Ministry of Agriculture.He was associated with import risk analysis (IRA) prior to introduction of Pacific white shrimp in India. Four candidates have been awarded Ph.Dunder his guidance and currently he is guiding two research scholars for Ph.D.in various areas of aquatic microbiology. So far he has handled five externally funded and three Institutional research projects as principal investigator (PI) and a number of other projects as co-investigator (Co-PI) in various areas of aquatic animal health management. He has generated financial resources to the tune of over Rs.170 lakhs as PI and over Rs.175 lakhs as Co-PI through external grants/schemes.He came toCIBA Chennai in March 1990 upon transfer from CMFRI on public interest, and initiated systematic research on the management of diseases in brackishwater aquaculture.He joined Agricultural Research Service at Central Marine Fisheries Research Institute (CMFRI), Cochin in April 1984 andcarried out research on the occurrence of heterotrophic microorganisms and mercury contamination in the coastal and marine waters.Prior to joining ICAR, he worked for a brief period in the Microbiology Department of St. Johns Medical College, Bangalore and Vector Control Research Centre, Indian Council of Medical Research, Pondicherry.
