Autobac
Summary
Autobac was an UnB project. The project’s goal was to develop machine capable of analyzing an Antibiogram autonomously and print a report of the test.
Problem
“Antibiotic susceptibility testing (AST) is usually carried out to determine which antibiotic is the most successful in treating a bacterial infection in vivo. Small wafers containing antibiotics are placed onto a plate upon which bacteria are growing. If the bacteria are sensitive to the antibiotic, a clear ring, or zone of inhibition, is seen around the wafer indicating poor growth. The results of the test are reported on the antibiogram.”1
In the disk diffusion test2, the zones sizes are usually measured by a human nowadays. This process takes time. However, a faster method can quickly select the best treatment to a new bacteria type in case of emergency. Professor Marcelino Andrade3 and his student Luan Costa saw this problem and developed a solution in MATLAB. Processing pictures taken of wafers with bacterias and antibiotics they could print a report where the antibiotics were ranked. They wanted to build a
