| Abstract | AIMS: To determine the genogroup distribution of F-specific coliphages in aquatic environments using the plaque isolation procedure combined with genogroup-specific real-time PCR. METHODS AND RESULTS: Thirty water samples were collected from a wastewater treatment plant and a river in the Kofu basin in Japan on fine weather days. F-specific coliphages were detected in all tested samples, 187 (82%) of 227 phage plaques isolated were classified into one of the 4 F-specific RNA (F-RNA) coliphage genogroups and 24 (11%) plaques were F-specific DNA coliphages. Human genogroups II and III F-RNA coliphages were more abundant in raw sewage than animal genogroups I and IV, excluding one sample that was suspected to be heavily contaminated with sporadic heavy animal faeces. The secondary-treated sewage samples were highly contaminated with genogroup I F-RNA coliphages, probably because of different behaviours among the coliphage genogroups during wastewater treatment. The river water samples were expected to be mainly contaminated with human faeces, independent of rainfall effects. CONCLUSIONS: A wide range of F-specific coliphage genogroups were successfully identified in wastewater and river water samples. SIGNIFICANCE AND IMPACT OF THE STUDY: Our results clearly show the usefulness of the genogroup-specific real-time PCR for determining the genogroups of F-specific coliphages present in aquatic environments. |

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.
