Antibiotic Sensitivity Test of Bacteria (With Diagram)

In this article we will discuss about the Antibiotic Sensitivity Test of Bacteria. Subcultures of the test organisms are made in broth and incubated for 6-18 hours. Any density of inoculum may be used but in most cases the surfaces of cultures plates may be sown with broth containing approximately 100 million cells per ml. After drying the surface, the [...]
