Babi Dairou

Babi Dairou lost a third of her goat herd in 2019, when a viral disease that attacked small ruminants such as sheep and goats spread through northern Cameroon.

And he was among the better off, Dairou said, as many of his neighbors lost all their animals to the devastating disease, known by its scientific name of peste des petits ruminants (PPR).

But now the goats of this factory worker and part-time farmer, as well as those of others in his village, are safe from the disease, thanks to a mass vaccination campaign under the PPR Global Eradication Program , supported by the IAEA, the Food and Agriculture Agency.

United Nations Organization (FAO) and World Organization for Animal Health.

PPR is endemic in the region (its spread is facilitated by the movement of wild animals and domesticated herds across borders) and, despite previous control campaigns, has returned to Cameroon.

In the north, where a narrow strip of Cameroonian territory cuts off the southern edge of the Sahel, the borders with Chad to the east and Nigeria to the west are never far away, so transboundary animal diseases can quickly invade.

This part of the country, known as the north and far north, is home to 80 percent of Cameroon’s livestock, said Gabriel Toumba, regional coordinator for the Livestock Development Project, a World Bank-backed program that coordinated the vaccination campaign in the land.

On average, 88% of small ruminants were vaccinated in each of the three years of the campaign, with vaccines produced by the National Veterinary Laboratory (LANAVET), located just 15 kilometers south of Garoua.

LANAVET produces 25 million doses of vaccines each year to combat various veterinary diseases that affect cattle, small ruminants and poultry.

It performs diagnosis and quality controls through the application of nuclear and related technologies (see The role of nuclear and related techniques in the diagnosis of PPR).

In fact, as a tour of its 1,200-square-meter plant reveals, about half of its equipment has been donated by the IAEA through its technical cooperation program and the VETLAB Network, a global network of national veterinary diagnostic laboratories.

coordinated by the Joint FAO/IAEA Center for Nuclear Techniques in Food and Agriculture based in Vienna, Austria.

The IAEA’s longstanding support, in partnership with the FAO, has included much more: the organizations have provided training and expert advice, as well as reagents and consumables to LANAVET to carry out its research and quality control work, Simon said.

This skills development, supplemented by regular advice from the IAEA, has led to the laboratory’s successful accreditation as ISO 17025 compliant, the only veterinary laboratory of its kind in Central Africa.

As a result, it has been able to increase its capacity and now supports several countries in the region by exporting seven different veterinary vaccines.

Livestock farmers in Benin, Burkina Faso, Chad, Côte d’Ivoire, Gabon, Ghana and Nigeria benefit from LANAVET’s support, including regional trainings and fellowships that it now offers, through the IAEA, to veterinary researchers from these countries.

In addition to diagnosing diseases and producing vaccines, LANAVET also performs quality control tests on veterinary drugs imported into Cameroon.

This also uses nuclear and related technologies.

An outbreak that spread rapidly It was the diagnosis by LANAVET experts in 2019 that confirmed the epidemic: 44% of the animals surveyed were infected.

After the campaign that led to the vaccination of around 5 million small ruminants across the country, less than 5 percent of the surveyed sample fell ill and the proportion continues to fall, Jumbo said.

“This is proof that LANAVET fulfilled the main objective of the project with the IAEA: to help alleviate the poverty of small farmers through PPR control by supporting the national vaccination program and informing the country’s vaccination strategy” Jumbo said.

While the campaign will end in January 2023, vigilance will be required, Toumba of the Livestock Development Project said.

The migration of wild ruminants and the mixing of herds herded across large tracts of land by pastoral farmers could trigger another outbreak at any time.

To mitigate this risk, the government will remain vigilant and use its vaccination and control strategy to quickly stop the thread of any new outbreak, he added.

Surveillance by farmers like Dairou will likely be necessary until 2030, the target year for global eradication of the disease set by the FAO, which supports countries in Africa in the fight against PPR.

“Only then can we be sure that PRPD does not come back from our neighbors,” Dairou said.

THE SCIENCE The role of nuclear and related techniques in PPR diagnosis Enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) are two techniques of nuclear origin used for disease diagnosis.

ELISA is easy to set up and use, making it suitable for any veterinary laboratory.

illness.

ELISA is often used for initial testing and screening of large populations, but cannot be used to accurately identify virus strains.

PCR is a nuclear-derived method for detecting the presence of specific genetic material from any pathogen, including a virus, in samples.

Originally, the method used radioactive isotope labels to visualize target genetic materials, but further refinement led to the replacement of isotopic labeling with specific labels, most often fluorescent dyes.
