Doctors collect swabs from birds at the Bhindawas bird sanctuary in Jhajjar, one of the two places in Haryana from where samples will be collected over three years for surveillance of AI virus.

Experts from Lala Lajpat Rai university of veterinary and animal sciences (Luvas), Hisar and University of Minnesota, US, and forest department officials will begin collecting samples from resident and migratory birds at the Sultanpur National Park for a three-year project on Monday.

Luvas had proposed a project, in collaboration with University of Minnesota, US, in 2016 to surveil migratory and resident birds for the Avian Influenza (AI) virus. The department of agricultural research and education, the Indian council of agricultural research, and the state forest department granted the requisite permissions in December 2017. A 12-day training programme was organised from February 5 to February 16 this year, at Hisar, where the project overview was discussed.

The project was proposed to research the emergence and recurrence of respiratory diseases in poultry that threaten animal and public health worldwide, said Dr NK Mahajan, principal scientist, veterinary public health and epidemiology, college of veterinary sciences, Luvas.

“The pursuit of this research will be helpful in advancing science to reduce the challenges of countering emerging disease threats of considerable economic impact to the poultry industry in India as well,” said Dr Mahajan.

The Sultanpur National Park, situated 15km from the city, will be one of the two places in Haryana where these samples will be collected from over a period of three years for surveillance of the virus. The other place is Bhindawas Bird Sanctuary in Jhajjar, where sampling was done in February and March. Though most migratory avian species have left Sultanpur, research on the resident birds will begin from Monday, said a state wildlife official.

According to him, only oral swabs will be taken from the migratory birds that are the probable carriers of the viruses.

“We have collected swabs from 20 bird species from Bhindawas Bird Sanctuary, Jhajjar. We plan to work at the Sultanpur Bird Sanctuary next and send the samples to Luvas. Also, we have been asked to send any dead birds we find so that they can monitor and collect samples to prevent the outbreak of bird flu,” said Dr Ashok Khasa, veterinary surgeon, wildlife, forest department.

The collection of samples from resident birds will be done till August and migratory birds will start flying in by September after which, they will be subjected to a sample collection process. Sultanpur sees a flurry of winged visitors in the winter — more than 30,000 birds from different parts of the world. At present, there are 35 species of residents birds here.

“Many species of these migratory birds are known carriers of the AI virus, which not only causes mortality and economic loss in the domestic poultry but is communicable to human beings. This sampling exercise will help in possibly stopping this,” said Haryana’s forest and wildlife minister Rao Narbir Singh.

In late 2016, a number of dead birds found in Rajpura, Punjab, had tested positive for bird flu (H5N8 avian flu). Following this, Haryana’s animal husbandry department had carried out a massive culling of birds and banned visitors to Sultanpur National Park fearing their exposure to migratory birds. The state government had also issued an advisory to all district headquarters for preparedness, control, and containment of the disease

FACT FILE

  • Avian Influenza is a viral infection that occurs naturally in wild birds, especially waterfowl, gulls, and shorebirds, and is carried without any outward symptoms. It is caused by type A influenza viruses that have 2 important surface antigens, hemagglutinin (H) and neuraminidase (N), that give rise to 144 possible virus subtypes.
  • Migratory birds fly from various countries including Russia, Siberia, and China and visit different regions every winter (September to March).
  • Sultanpur National Park and Bhindawas Bird Sanctuary are a haven for migratory and resident birds. In winters, Sultanpur becomes a stopover for approximately 150 species of migratory birds.
  • Sampling done in Bhindawas on birds includes Rosy pelican, Gadwall, Comb duck, Black-headed ibis, Eurasian coot, Ruddy shelduck, Bar-headed goose, Pintail, greylag goose and painted stork.
  • Haryana has two national parks, eight wildlife sanctuaries, two wildlife conservation areas, four animal and bird breeding centres, one deer park, and 49 herbal parks.
