APOPO's work in Mozambique

The HeroRATs save thousands of lives
The HeroRATs save thousands of lives

The first APOPO TB research laboratory was established in Morogoro, Tanzania in 2005. Since 2008, the HeroRATs have delivered promising results, with a reported increase of 43% in the tuberculosis detection rates in the samples evaluated. There are now a total of 17 collaborating clinics in Dar es Salaam, 178,425 sputum samples screened since 2007, and 3,788 TB positives identified by rats after being missed by microscopy.

With the aim of replicating the results obtained in Tanzania, APOPO opened its operations in the Republic of Mozambique earlier this year, thus contributing to the Ministry of Health efforts to control tuberculosis in the country. To conduct the research, a laboratory was built at Eduardo Mondlane University’s Veterinary School grounds and opened on June 28th, 2013. APOPO rats will evaluate the samples coming from patients with suspected tuberculosis, and any positives will be confirmed using fluorescence microscopy techniques. So far, there are 8 participating units in Maputo, and a total of 7,210 sputum samples screened since January. 

In regards to APOPO mine action, last week 26 Mine Detection Rats (MDR’s) were deployed to Mozambique. These rats will go through a period of acclimatization and training in order to pass an official external accreditation test according to International Mine Action Standards (IMAS). Once accredited, the rats and their trainers will be officially licensed for operational work and can begin to work with their HeroRAT colleagues in the minefields. So far, a total of 2,406 landmines have been found and neutralized. A total of 6,423,361m2 of land has been returned to the population, safe to be used for agriculture and grazing.

Hamisi the HeroRat has started training!

Hamisi learning to detect TB
Hamisi learning to detect TB

Dear Supporters, 

Thank you for your life-saving support to APOPO.  Due to your generosity, we have started training Hamisi, the HeroRat, to detect Tuberculosis (TB).  Here is what the journey of Hamisi will entail over his nine month training process.  This process forms the foundation for a successful 6-7 year lifespan of the TB detection rat to significantly impact the spread of tuberculosis.

3-4 weeks of age 

At 3-4 weeks old the baby rats can open their eyes and at this time they still live with their mothers, but minimal socialization by one of our caretakers can begin.

5-6 weeks of age

The rats are weaned from their mother, and they begin a period of socialization.  During this period, the caretaker and trainers expose the rats to different smells, sounds and textures, for example hearing music or a motorcycle engine, smelling flowers or coffee, exploring different surfaces like grass, concrete and soil, and going for a ride in the HeroRAT truck. This is an essential part of the training process: the rats need to feel comfortable and relaxed in the human environment they will be working in, to ensure they are not afraid.

Click training

After two weeks of nursing, the rats begin click training twice a day, in approximately 5 minute sessions. Here they learn to associate the “click” sound with a food reward. This takes place in a square glass-walled cage, with a small food hole in one wall. Immediately after the rat hears the “click”, the trainer gives them a mouthful of mushed banana and crushed pellets. Click training takes one-two weeks.

One hole and Three hole

Once the rats learn that “click” means food, trainers can begin to teach the rats that they must now find something in order for the “click” and subsequent food reward. They start with one hole in a three-hole cage. When the rat goes to the hole, they hear a “click” and must learn to return to the food hole to receive their reward. They do this twice a day for one week, for 5-10 minute sessions. Once the rat has learned to go to one hole and then respond correctly to the clicker, trainers begin to introduce more holes (3), with one positive and two neutral samples for a few weeks.

Multiple Sample Evaluation

The rat will move to a larger cage, which holds sample bars with each 10 samples under sniffing holes in a long stainless steel plate. In this training stage, the rat learns to evaluate large numbers of samples.  The rat is then trained in this setup for several months until the accuracy rate is at an acceptable level.  

TB Rat accreditation

APOPO's TB rats must pass an internal accreditation process before working under operational conditions. The test is conducted under blind conditions and to pass the rat must find every positive patient. 

Once Hamisi is accredited, Hamisi will then work for the next 5-6 years detecting thousands of sputum samples and detecting hundreds of TB patients originally missed by hospitals.

From APOPO and the future beneficiaries that Hamisi will help, a huge HeroRAT thank you!!

Surviving the landmines: APOPO's work in Thailand


Thailand offers its hospitality to millions of tourists every year and has become one of the biggest and most attractive tourist destinations in the world, charming its visitors with a rich array of history, culture, architecture and food. Yet few are aware of a considerable mine problem along the borders, especially with Cambodia, and that people living in these areas suffer from landmine accidents, fear of accidents and limited access to arable land.

What is it like to survive dangerous landmines? Watch this video, which features interviews with survivers, on APOPO's work in Thailand: http://www.youtube.com/watch?v=yApYLbESJl0

APOPO has built upon the excellent start in Thailand in 2011 where it implemented a Non-Technical Survey (NTS) program along the Thailand-Cambodia border. APOPO has partnered with a local Thai NGO, Peace Roads Organisation (PRO) and has been working closely with the Thailand Mine Action Centre (TMAC) to systematically survey all minefields along the border in Trat & Buriram Provinces.

NTS gathers detailed information about mined areas including the number of mines, location and size. The consequence of this NTS process is that considerable time, effort and money will now not be wasted clearing land unnecessarily. This then increases the efficiency and effectiveness for the mine action programs and will assist Thailand meet its mine ban treaty obligations.
