| Abstract | Vibrio spp. as natural inhabitants of sea- and brackwater of both tropical and temperate regions of the world are commonly found in different kinds of seafood. Even among the three main human pathogenic species Vibrio parahaemolyticus, Vibrio cholerae and Vibrio vulnificus most of the isolates from seafood do not carry the different virulence factors responsible for foodborne infections. Therefore, the risk assessment of Vibrio spp. in seafood is currently based mainly on the knowledge of the genetic setting of foodborne strains. For the detection and differentiation of Vibrio spp. (V. parahaemolyticus, V. cholerae and V. vulnificus) three probe-based multiplex real-time PCR systems were developed and validated. One real-time PCR system simultaneously detects V. parahaemolyticus, V. cholerae and V. vulnificus on genus level combined with an Internal Amplification Control. The detection limit for the system was between 1cfu/mL and 10cfu/mL in pure culture and in different artificially contaminated sample material, e. g. prawns or Alaska Pollock. The other two PCR systems were implemented for the detection of different virulence genes of V. parahaemolyticus and V. cholerae isolates. The molecular detection systems were applied for the investigation of 338 raw and cooked seafood and fish samples for the presence of the different Vibrio spp. The collected data indicate that the PCR systems can be useful for rapid detection and differentiation of Vibrio spp. in different food matrices as basis for a preventive consumer protection policy. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
