Molecular and Genetic Epidemiology - Essay Example

“Molecular and Genetic Epidemiology” Snow, M. . The contribution of molecular epidemiology to the understanding and control of viral diseases of salmonid aquaculture. Veterinary Research.42(56). Available at http://www.veterinaryresearch.org/content/42/1/56/abstract. [Accessed on 13th April 2011]. Molecular epidemiology, a science that spotlights and employs genetic as well as environmental jeopardy to define, the etiology, distribution and prevention of disease in a family or in a given population.

It is an amalgamation of molecular aspects and analytical epidemiological approaches. The study aims on molecular epidemiology approach to learn viral pathogens of aquaculture with dynamic approach to control the disease in aquaculture. The study emphasize on viral disease of salmonid fish; grounds, viral haemorrhagic septicaemia virus (VHSV), salmonid alpha virus (SAV) and infectious salmon anaemia virus (ISAV). Noteworthy upshots of molecular epidemiological incorporation to pursue the study encompass enhanced taxonomic categorization of viruses, an improved perception about natural allocation of viral strains, an augmented discernment about the derivations of viral strains in aquaculture, molecular epidemiological incorporation improves an access to understand the hazards caused due to translocation of pathogens as well as how viral strains outsmart their accepted host range.

The process enhances the capability to mark out the basis of new-fangled infection outbursts. The process thereby enables the researchers to formulate the basis of expansion with suitable upgrading if desired in diagnostic tools. The most imperative provision that researcher procure is the capability to categorize isolates procured with the molecular epidemiological procedures and therefore aims at better future research aspects. The introduction of new expertises like pyrosequencing enables researchers to produce explanatory molecular sequence data.

With the amalgamation of molecular and genetic approaches in epidemiological studies, future is vivid in revealing the translation of complex disease pathways which are relevant with the maintenance of perfect fish health in aquaculture. The pathways are traced using the genetic markers. Viral transmission pathways could be further traced using molecular probes and markers to identify their signalling pathways. The process thus aids in meeting the challenges that are being imposed by aquaculture viruses on fish health.

The process therefore could be used to procure molecular data related with fish health procedure and disease management.
