Streptococcus disease vaccine for cattle, how does it work and how does the disease affect cattle

The Government of India has developed a vaccine for streptococcus disease in cattle and is confident that it will be available in the market soon.

The development of the streptococcal disease vaccine comes at a time when several thousand cattle have died from the disease in several Indian states.

The Indian Council of Agricultural Research (ICAR), the government body under which the vaccine was manufactured, claimed it was 100 per cent effective. Until now, goat and sheep pox vaccines were administered to cattle to prevent streptococcus disease, which were only 60-70 percent effective.

Here we explain what streptococcus disease is, how the vaccine against it was developed and how it works, and how streptococcus disease has affected livestock across India.

What is lumpy disease and how does it affect livestock?

Streptococcus disease is a viral disease spread by the bites of insects such as some species of flies, mosquitoes and ticks, according to the European Food Safety Authority (EFSA).

The European Food Safety Authority notes that “it causes fever and nodules on the skin and can also lead to death, especially in animals not previously exposed to the virus.”

Streptococcus disease first came to India in 2019, according to a press release from the Union’s Ministry of Agriculture and Farmers Welfare.

prospects The Department of Animal Husbandry said earlier that the disease, which originated in Africa, reached India this year via Pakistan in April. Since then, several thousand cattle in several states have died after developing lumps on their bodies after contracting the virus.

ICAR streptococcal disease vaccine

ICAR’s National Equine Research Center (NERC) in Haryana has developed a streptococcal disease vaccine named Lumpi-ProVac Ind in collaboration with the Indian Institute of Veterinary Research (IVRE) in Uttar Pradesh Bareilly.

Development of the vaccine began in 2019 and the successful development was announced in August in the midst of a nationwide outbreak.

The Federal Ministry of Agriculture said in a press release that Union Minister of Agriculture and Farmers Welfare Narendra Singh Tomar directed the concerned officials to introduce strep vaccine in large numbers as soon as possible for livestock relief. It further quoted Tomar as saying that there are 30 crore livestock in the country and given the plight of the dumb animals, all possible measures should be taken to provide relief to them as soon as possible.

Indian Express reported that Lumpi-ProVac Ind is a live attenuated vaccine, similar to the vaccines against tuberculosis (TB), measles, mumps, and rubella. These types of vaccines provide stronger, longer-lasting protection.

“Live vaccines use a weakened (or attenuated) form of disease-causing germs. Because these vaccines are so similar to the natural infections they help prevent, they create a strong, long-lasting immune response. Inactivated vaccines use a dead version of the disease-causing germs. Usually Inactivated vaccines do not provide as strong (protection) immunity as live vaccines,” says the US Department of Health and Human Services.

Tell Navin Kumar, Principal Scientist at NRCE Express That the NRCE collected skin samples from infected cattle in 2019 and isolated the virus in early 2020. Then a process called “culturing” was carried out for 17 months, the purpose of which was to weaken the virus’s tolerance to disease with each round of culture.

Tests on mice and rabbits began after the 50th round of breeding and trials on cattle began in April of this year. Trials so far have shown 100 percent efficacy.

When will the streptococcal disease vaccine be available?

While the government has said it is confident that a strep vaccine will soon be available on the market, there is no timetable available and it is expected that it will take some time.

The vaccine has only been developed so far and no contract has been concluded with a company that would produce it on a large scale to bring it to market. However, three companies have expressed interest in producing the vaccine, according to a report.

“Agrinnovate India, the marketing arm of products and technologies developed by our institutes, issued an Expression of Interest document last week. Three companies have already expressed interest,” said Bhupendra Nath Tripathi, Deputy Director General (Animal Sciences) at ICAR. , to me Express.

As of now, the goat and sheep pox vaccine is given because streptococcus disease belongs to the same family of viruses, and these two vaccines provide a certain degree of protection against streptococcus disease.

Streptococcal disease outbreak in India

The current streptococcal disease is spreading in 12 Indian states and the Union Territory, infecting large numbers of animals and killing several thousand.

About 11.21 lakh cattle have been injured and 49,628 have died so far, according to official data available until the end of August.

Cases of the virus have been reported in Rajasthan, Gujarat, Punjab, Haryana, Uttar Pradesh, Jammu and Kashmir, Himachal Pradesh, Madhya Pradesh, Uttarakhand, Maharashtra, Goa, Andaman and Nicobar.
