Opinion article by Prof Frikkie Maré, Department of Agricultural Economics, University of the Free State.
In William Shakespeare’s play Julius Caesar, Mark Antony utters the words: “Cry ‘Havoc!’, and let slip the dogs of war,” after learning about the murder of Julius Caesar. With these words he meant that chaos would ensue (havoc) to create the opportunity for violence (let slip the dogs of war).

The recent invasion (or military operation, according to Russian President Vladimir Putin) by Russian armed forces into Ukraine brought the famous words of Shakespeare to mind. Putin cried “Havoc!” and his troops created chaos in Ukraine. This is, however, not where it stopped because the dogs of war have been released into the rest of the world.

What is the impact on South Africa?

The day after the invasion we felt the bite of the dogs of war in South Africa. The rand suddenly weakened against the dollar, oil and gold prices increased sharply, and grain and oilseed prices on commodity markets increased 

This was before the rest of the world started to implement sanctions against Russia, which could be described as a shock reaction due to uncertainty as to how the situation would unfold. In the days after the initial market reaction we saw the markets actually “cool down” a bit, with most sharp initial reactions starting to change back to former positions. This period was, however, short-lived when the world hit back by closing airspace and borders and refusing to import products from Russia or export to them. The sanctions were in solidarity with Ukraine as an attempt to bring the Russian economy to its knees and force the Russians to withdraw from Ukraine.

Although the sanctions against Russia should certainly be successful over the long term, it does not change much in the short term and we will have to deal with the international effects of this conflict. The question then is, how will this affect South Africa?

Although there are no straightforward answers, as the impact will depend on what one’s role is in the economy. One thing for certain is that the total cost will outnumber the benefits. What affects everyone in South Africa, and the starting point of many secondary effects, is the increase in the price of crude oil. Russia is the second-largest producer of crude oil in the world and if the West is going to ban the import of Russian oil we will have an international shortage. Although the banning of Russian oil is the right thing to do to support Ukraine, it will have devastating effects on all countries in the world, with sharp increases in inflation.  

The increase in the price of oil not only drives up the cost of transportation of people and products, but also manufacturing costs. Fertiliser prices are correlated with the oil price, and it will thus drive up the production cost of grain and oilseeds.

Speaking of grain and oilseed prices, the Black Sea region (which includes Russia and Ukraine), are major exporters of wheat and sunflower seed and oil. The prices of these commodities have soared in international and South Africa markets over the past few weeks. Although it might seem like good news for our farmers, the increase in prices are offset by high fertiliser prices and the local shortage of fertiliser. This may lead to fewer hectares of wheat being planted this year in the winter rainfall regions.  

Nothing good is coming from this situation

In terms of agricultural commodities, both Russia and Ukraine are important importers of South African products, especially citrus, stone fruit and grapes.  Alternative markets now need to be found for these products which will affect prices negatively.

Although one needs to write a thesis to explain all the effects of the Russian-Ukraine conflict, the dogs of war have been slipped, and it is clear from the few examples that nothing good is coming from this situation. In short, we will see higher fuel prices (maybe not R40/litre, but R25 to R30/litre is possible), higher food prices, higher inflation and a higher interest rate.  

These factors affect all South-Africans, especially the poor and some in the middle class who will struggle in the short term. The time has come to cut down on luxuries and tighten belts to survive in the short term until there is certainty about how the havoc in Ukraine will play out.

A summary of an inaugural lecture delivered by Prof Robert Bragg at the University of the Free State:

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
