The investigation of infectious diseases is carried out in microbiology. The pathologists and scientists working here look for specific bacteria, viruses, fungi and parasites that may be causing a patient’s symptoms.

 The work can involve growing (or culturing) a particular bacteria in an incubator that mimics the perfect environment for the microorganism, then examining the results under the microscope (microscopy). This lab also measures the susceptibility of the bacteria to antibiotics to help decide on treatment.
