Researcher works at microscope in Histology Lab
Tissue sections are mounted on glass slides, stained and examined with a microscope that magnifies cellular details up to 2,000 times with brightfield or fluorescence imaging. Microscopes are used in our research to understand the pathological changes caused by infectious agents such as bacteria, fungi, parasites and viruses.
