Tanzanian science catches up

Tanzania’s first-ever machine for rapid analysis of multiple DNA samples has been welcomed by scientists, who say it will revolutionise their research.

The equipment can analyse 96 samples in an hour. Until now, researchers have had to perform a manual analysis that takes 72 hours for a single sample, take a bus to a neighbouring country, or a plane to a First World country.

“It is the first time we have had such a machine in Tanzania,” said Gloria Tom Machuve, head of forensic biology at the Government Chemist Laboratory Agency, where the machine was installed. “It is a saviour to the research sector.”

Machuve said in the rest of sub-Saharan Africa, only Botswana and South Africa have similar machines — one in Kenya is now out of order.

Machuve said the analyser has a range of uses, such as medical research and disease diagnosis, crime detection and agricultural research, including studies of both livestock and crops.


Private institutions and universities conducting research have been invited to use the $300 000 genetic analyser, as long as they abide by government protocols regarding its use.

“If there is any good news this year for our university, then it is the arrival of the genetic analyser machine,” said Frances Magingo, head of botany at the University of Dar es Salaam.

“We used to take genetic samples to Sweden … our master’s degree students in molecular biology had to board buses to Nairobi for genetic analysis.”

Magingo said having the machine will remove the need for such travel, and attendant costs.

“The machine will solve a lot of research problems,” said Magingo. “You will go with your sample in the morning and in the evening have the results.”

But Machuve warned the lab also needs more personnel trained to use the analyser, made by Applied Bio Systems in Japan.

“Currently we have only three experts,” says Machuve. “We need to have at least 12 experts trained to master’s level to manage and run the machine efficiently.” — SciDev.Net

Smoking out nicotine-free tobacco in Tanzania

Tanzania's minister of agriculture has said that genetically modified (GM), nicotine-free tobacco is being grown in the country for research purposes. Yet, Tanzania's planned regulatory framework for genetically modified crops has still to be debated by Parliament. According to the minister, the genetically modified tobacco has been growing for fewer than three months on a small farm in the area.
