Ebeth Grobbelaar is a Scientific Manager in the South African Doping Control Laboratory (SADoCoL) who is responsible for the review and approval of results at SADoCoL, to ensure compliance with the technical requirements of the World Anti-Doping Agency (WADA).

For Ebeth Grobbelaar, Scientific Manager in the South African Doping Control Laboratory (SADoCoL) – which is housed by the University of the Free State (UFS) – her work at the laboratory is profound, as fairness on and off the playing field is vital to her.

“Creating a fair playing field for athletes to compete carries a heavy responsibility, as an anti-doping violation impacts the athlete’s career,” says Grobbelaar, who is responsible for the review and approval of results at SADoCoL to ensure compliance with the technical requirements of the World Anti-Doping Agency (WADA).

Women are the cogs in the wheel

According to her, anabolic steroids, the multiple analytical disciplines, and rapidly changing technical requirements from WADA have attracted her to the sciences of anti-doping. Sixty percent of her colleagues at SADoCoL are women.  “They are the cogs in the wheel, ensuring the laboratory's smooth operation, taking daily challenges in their stride, and excelling in what they do as analysts and administrative staff,” says Grobbelaar.

Grobbelaar says there are many options in the anti-doping field for women inside and outside of the laboratory. Some of the most influential people in the anti-doping community are women – in their roles as laboratory directors, leading researchers, directors of athlete passport management units for international sports federations, or national anti-doping agencies in various capacities.

With all the responsibilities, come challenges and pressure – especially in a year when the Olympic Games take place. 

Women should learn how to say ‘no’ 

“An Olympic year always has additional stress due to the large number of samples before the games. This year, the pressure is more, with not all accredited laboratories operational, as well as disrupted testing schedules due to COVID-19.  Enabling athletes to compete in fairness on the world stage is a responsibility and a privilege.”

“My faith is my anchor.  As far as possible, I try to leave my work behind when I leave the laboratory, and concentrate on enjoyable things such as gardening, my dog, reading, and walking with my dog. On challenging days, something sweet also helps,” explains Grobbelaar the pressure and how she copes with it. 

This Women’s Month, Grobbelaar says, women should learn how to say ‘no’ to create time for rest and play. Says Grobbelaar: “For many women, ‘doing your best’ or saying yes means working yourself to the point of a mental and physical breakdown. Having the courage to say no, loving oneself through rest and play, replenishing our spirits, and realising that we are unique and precious in God’s eyes, is a challenge that many women face.” 

“Rest and play can take different forms, such as having coffee with a friend or being creative.  The important thing is that your rest or play activity brings joy to your soul and energises you. Ask your friends to support and assist you,” she concludes.

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.
