Rhizospheric soil of Typha angustifolia L. from heavy metal contaminated and free sites: Comparative profiling reveals selective abundance of γ-proteobacteria and β-proteobacteria

Typha angustifolia L. commonly called Lesser bulrush or Narrowleaf cattail, is one of the most predominant flora of the heavy metal enriched wetland of Jaduguda Uranium mine tailings, India. The luxurious growth of this plant is due to its ability to tolerate heavy metals, such as iron and manganese.This plant also grows abundantly in natural wetlands of Kolkata. Rhizospheric eubacterial community of Typha growing in Jaduguda and Kolkata were compared by cloning of 16SrDNA sequences followed by ARDRA (Amplified rDNA Restriction Analysis) and sequencing of unique clusters. Sequencing results were subjected to computational analysis. In the natural wetland of Kolkata, the predominant group of eubacteria was found to be β-proteobacteria, which isabsent in heavy metal enriched wetland of Jaduguda where γ-proteobacteria was found to be predominant. The data was statistically validated using a simple χ2 test which established the diversity of the populations in context to the bioavailability of heavy metals

Media Scanning as a Supplemntal tool to Disease Outbreak Reporting und)er IDSP-IndiaAn event based surveillance Project (IDSP).

Media scanning & verification cell (MSVC) was established on 24th July 2008 under IDSP at National Centre for Disease Control (NCDC), Delhi for providing supplemental information on early detection of outbreaks in India so that a timely and an appropriate action can be taken. Since then the system is working efficiently and has detected many outbreaks before the conventional system in their incipient stages and helped in their containments at early stages. Media scanning & verification cell is an “Early Warning System” (EWS) that gathers preliminary reports of public health significance on a real time basis and immediately disseminate the information to the users electronically for verification. This unique system monitors Global and National Media sources such as National and Regional print media, news on internet, websites, news channels and news shared by partners like Global Public Health Intelligence Network (GPHIN), Canada, WHO and other International and national agencies. Media scanning & verification cell is managed by trained Epidemiologists and Public Health Consultants working in Central Surveillance Unit of IDSP. The major part of work is manual with two rounds of screening by experts that fulfills issues regarding quality assurance.
