Spread of life threatening ‘superbugs’ haunts Ganges river

superbug and ganges pilgrimage

Experts reveal the spread of antibiotic-resistance to one of the most pristine locations in Asia is linked to the annual human pilgrimages to the region. The research team are now calling on governments around the world to recognize the importance of clean drinking water in our fight against antibiotic resistance.

The spread of antibiotic-resistance to one of the most pristine locations in Asia is linked to the annual human pilgrimages to the region, new research has shown.

Experts from Newcastle University, UK, and the Indian Institute of Technology in Delhi (IIT-Delhi), sampled water and sediments at seven sites along the Upper Ganges River, in the foothills of the Himalayas.

They found that in May and June, when hundreds of thousands of visitors travel to Rishikesh and Haridwar to visit sacred sites, levels of resistance genes that lead to “superbugs” were found to be about 60 times greater than other times of the year.

Publishing their findings today in the journal Environmental Science and Technology, the team say it is important to protect people visiting and living at these sites while also making sure nothing interferes with these important religious practices.

They argue that preventing the spread of resistance genes that promote life-threating bacteria could be achieved by improving waste management at key pilgrimage sites.

“This isn’t a local problem – it’s a global one,” explains Professor David Graham, an environmental engineer based at Newcastle University who has spent over ten years studying the environmental transmission of antibiotic resistance around the world.

“We studied pilgrimage areas because we suspected such locations would provide new information about resistance transmission via the environment. And it has – temporary visitors from outside the region overload local waste handling systems, which seasonally reduces water quality at the normally pristine sites.

“The specific resistance gene we studied, called blaNDM-1, causes extreme multi-resistance in many bacteria, therefore we must understand how this gene spreads in the environment.

“If we can stem the spread of such antibiotic resistant genes locally – possibly through improved sanitation and waste treatment – we have a better chance of limiting their spread on larger scales, creating global solutions by solving local problems.”

Funded by the Engineering and Physical Sciences Research Council (EPSRC), the aim of the research was to understand how antibiotic resistance was transmitted due to a specific human activity. Local “hot-spots” of antibiotic resistance exist around the world, particularly densely-populated regions with inconsistent sanitation and poor water quality.

By comparing water quality of the Upper Ganges in February and again in June, the team showed that levels of blaNDM-1 were 20 times higher per capita during the pilgrimage season than at other times.
Monitoring levels of other contaminants in the water, the team showed that overloading of waste treatment facilities was likely to blame and that in many cases, untreated sewage was going straight into the river where the pilgrims bathe.

“The bugs and their genes are carried in people’s guts,” explains Professor Graham. “If untreated wastes get into the water supply, resistance potential in the wastes can pass to the next person and spiralling increases in resistance can occur.”
Concern over the spread of Antibiotic-Resistant (AR) genes

Worldwide, concern is growing over the threat from bacteria that are resistant to the so-called “last resort” class of antibiotics known as Carbapenems, especially if resistance is acquired by aggressive pathogens.

Of particular concern is NDM-1, which is a protein that confers resistance in a range of bacteria. NDM-1 was first identified in New Delhi and coded by the resistant gene blaNDM-1.

Until recently, strains that carry blaNDM-1 were only found in clinical settings, but in 2008, blaNDM-1 positive strains were found in surface waters in Delhi. Since then, blaNDM-1 has been found elsewhere in the world, including new variants.

There are currently few antibiotics to combat bacteria that are resistant to Carbapenems and worldwide spread of blaNDM-1 is a growing concern.

Professor Graham, who is based in the School of Civil Engineering and Geosciences at Newcastle University, UK, said the team had planned to repeat their experiments last year, but the region was hit by massive floods in June and the experiments were abandoned.

The team has since returned to Rishikesh and Haridwar and hope their work will prompt public action to improve local sanitation, protecting these socially important sites. On a global scale, they want policymakers to recognise the importance of clean drinking water in our fight against antibiotic resistance.

“What humans have done by excess use of antibiotics is accelerate the rate of evolution, creating a world of resistant strains that never existed before” explains Graham.

“Through the overuse of antibiotics, contamination of drinking water and other factors, we have exponentially speeded-up the rate at which superbugs might develop.

“For example, when a new drug is developed, natural bacteria can rapidly adapt and become resistant; therefore very few new drugs are in the pipeline because it simply isn’t cost-effective to make them.

“The only way we are going to win this fight is to understand all of the pathways that lead to antibiotic resistance. Clearly, improved antibiotic stewardship in medicine and agriculture is crucial, but understanding how resistance transmission occurs through our water supplies is also critical. We contend that improved waste management and water quality on a global scale is a key step.”

Himachal Gets First Fully Automated ‘Doppler Weather Radar’, Would Provide More Accurate Short Range Forecast

Published

Dopper Weather Radar in Himachal Pradesh's Kufari

Shimla-India Meteorological Department (IMD) January 15, 2021, celebrated its 146th Foundation Day. IMD is one of the oldest, scientific service organizations in the country, in existence well before Independence.

On the occasion, Dr. Harsh Vardhan inaugurated Doppler Weather Radars at Mukteshwar, Uttarakhand and Kufri, Himachal Pradesh; Multi-Mission Meteorological Data Receiving and Processing System in IMD in collaboration with ISRO (MMDRPS).

According to the IMD, these modernized Radars would give a more specific short-range weather forecast.

It’s pertinent to mention that accurate and advance weather information is of utmost importance to Himachal Pradesh – a state largely dependent on agriculture and tourism.

The one installed in Kufari, Shimla, is Indigenous dual polarised X-Band Doppler Weather Radar. Two more Radars would be installed at Mandi and Dalhousie in Chamba district of the State. A site had already been finalized at Mandi and a site for Radar at Dalhousie would be finalized soon, the State Government informed.

This specific type of Radar uses the Doppler effect to gather velocity data. The Radar transmits a signal, which gets reflected when hits a raindrop. Based on the changes in the frequency of the reflected signal, data is obtained about the motion of droplets and intensity of the precipitation. Scientists can analyze this data to determine the structure and severity of storms.

Radar installed at Kufri is on test mode for a period of two weeks. Thereafter its data would be used for forecasting purposes. This Radar has a range upto 100 kilometres in radial distance. It would observe and provide the weather data of 100 kilometres in all directions, which would be used for forecasting purpose, especially for the short-range forecast. More précised area-specific weather forecast and warning can be issued for a particular place, for the weather phenomenon like thunderstorm, lighting, hailstorm, heavy rainfall/snowfall, gusty winds etc.    

This Centre would help the horticulturists and farmers of the State by providing them with accurate weather information.

The DWR Kufri would run round the clock and it is fully automatic. It would transmit the data in various digital format and picture form.

 Forecasting monsoons is the lifeline to India’s food security and affect the economy as the nation’s GDP is dependent on agriculture. Moreover, weather prediction is critical to reducing the loss of lives from various extreme events like a cyclone, heavy rain, thunderstorm, heatwave and cold wave, monsoonal floods and droughts.

India Meteorological Department says that it is modernizing its observational network in the Central and Western Himalayas by the installation of Doppler Weather Radars in a phased manner, at different locations.

IMD said that this radar will be providing severe weather information to the weather forecasters, thus, improving the safety of the public in the states of Uttarakhand and Himachal Pradesh. It will also provide support to the disaster managers and the pilgrims undertaking the pilgrimage to Kailash Manasarovar and Char Dham yatra.

MEE Rank himachal pradesh GHNP

Shimla-The Great Himalayan National Park and Tirthan Wildlife Sanctuary (WLS) have been ranked as the best managed protected areas in India. Sainj WLS has also been placed among the top five Sanctuaries.

Minister for Environment, Forest and Climate Change, Prakash Javadekar, on January 11 released Management Effectiveness Evaluation (MEE) of 146 National Park and Wildlife Sanctuaries in the Country. At present, India has a network of 903 Protected Areas in the country covering about 5% of the total geographic area of the country. The purpose of it was to assess the efficacy of Protected Areas, evaluation of management effectiveness.

The evaluation process was executed by the Wildlife Institute of India, Dehradun, in which  nation-wide 146 National Parks and Wildlife Sanctuaries, including 13 protected areas of Himachal Pradesh, were assessed through a team of evaluators. The score is given for various parameters including staff position, provision of financial resources, degree of protection, peoples’ participation and awareness of the communities towards the conservation values. Against a national average of 62 percent GHNP and Tirthan WLS scored a high of 84.17 percent while Sainj recorded 82.5 percent.

Currently, Himachal Pradesh has a network of 5 National Parks, 28 Wildlife Sanctuaries and 3 Conservation Reserves covering 8391.42 km2 which is 15 percent of the total geographical area of the state.

What is Management Effectiveness Evaluation (MEE)?

Protected area (PA) management effectiveness evaluation (MEE) is defined as the assessment of how well NP&WLS are being managed—primarily, whether they are protecting their values and achieving the goals and objectives agreed upon.

The term ‘management effectiveness’ reflects three main themes of PA management -design issues relating to both individual sites and PA systems, the adequacy and appropriateness of management systems and processes, and delivery of the objectives of NP&WLS, including conservation of values.

 Management Effectiveness Evaluation (MEE) of Protected Areas (PAs) has emerged as a key tool for PA managers and is increasingly being used by governments and international bodies to understand the strengths and weaknesses of the protected area management systems.

MEE is a very important document that provides valuable guidance on various aspects of wildlife and protected area expand MEE of Marine Protected Areas. A new framework for MEE of Marine Protected Areas has been also jointly prepared by WII and MoEF&CC.

In recent years there has been a general concern amongst PA professionals and the public that many NP&WLS are failing to achieve their objectives and, in some cases, are actually losing the values for which they were established (Hockings et al. 2008).

As a result, improving the effectiveness of PA management has become a priority throughout the conservation community. Protected areas that are effectively managed generally lead to improved biodiversity outcomes.

However, only 20% (21,743 NP&WLS) of the total coverage of protected areas reported in the WDPA has been assessed for management effectiveness according to the Global Database on Protected Areas Management Effectiveness (UNEP-WCMC, IUCN and NGS 2018). The result indicated that only 17.5% of the countries have achieved the 60% score of management effectiveness (Coad et al. 2015).

Further, Javadekar also announced that from this year onwards 10 best National Parks, 5 coastal and Marine parks and top five Zoos in the country will be ranked and awarded every year.

Poultry ban in himachal pradesh

Shimla-Import of poultry products to Himachal Pradesh from other States has been banned for a week, the State Government informed today. The step was taken in order to ensure that the Bird Flu (Avian Influenza) infection does spread from other States through poultry products.   

According to the Government, the “Bird Flu death toll” for migratory birds has reached 4324. The Government said that about 65 rapid response teams of Animal Husbandry and Wild Life departments were regularly monitoring the Pong Dam and adjoining areas. It said that keeping in view the intensity of Bird Flu, samples of poultry have been sent to RDDL Jalandhar by Animal Husbandry Department. 

Further, recently 1000 dead domestic poultry birds were found dumped in Dharampur Sub Division of Solan district, which were disposed of by deep burial and area was being sanitized as per protocol, it was informed. Samples of these dead birds have been sent to RDDL Jallandhar for diagnosis.

Further, it was informed that 215 other birds were also found dead in various parts of the State till date.

Officers have been asked to keep a strict vigil on birds alongside reservoirs and people to sensitize about proper handling of poultry products.

The Government has requested the people to inform the Animal Husbandry and Wild Life Departments if any dead bird is found in their areas.

Bird Flu Confirmed in 10 States

According to the official statement released by the Government of India, till January 11, 2021, Avian Influenza was confirmed in 10 states of the country. ICAR- NIHSAD has confirmed death of crows and migratory/wild birds in Tonk, Karauli, Bhilwara districts of Rajasthan; and Valsad, Vadodara and Surat districts of Gujarat. Further, death of crows was confirmed in Kotdwar and Dehradun districts of Uttarakhand. In Delhi, crows and ducks, respectively, were reported dead in New Delhi and Sanjay lake areas.

Additionally, an outbreak of Avian influenza has been among poultry in Parbhani district where 800 hens died of the Flu. Also, the Flu is confirmed from Mumbai, Thane, Dapoli, Beed in crows in Maharashtra.

Culling of Infected Birds Underway in Haryana

In Haryana, culling of infected birds is underway for the control and containment of the spread of the disease. A Central team has visited Himachal Pradesh and will reach Panchkula on 11 January 2021 for carrying out monitoring the epicentre sites and conducting epidemiological investigation.

States have been requested to build awareness among the public and avoid the spread of misinformation. States/ UTs have been requested to increase surveillance around water bodies, live bird markets, zoos, poultry farms, etc. along with proper disposal of carcasses and strengthening of bio-security in poultry farms.

The States have been asked to maintain adequate stock of PPE kits and accessories required for culling operations, Secretary, DAHD, requested.
