Introduction to Microbiology

1. Microbiology Lecture GBSN (Unit 1) by, Miss Areesha Ahmad Lecturer Microbiology B.Sc (H), M.Sc , M.Phil and Ph.D scholar (Microbiology)

2. Light Microscopy Immersion microscopy In  light microscopy ,  oil immersion  is a technique used to increase the  resolving power  of a  microscope .  Dark field microscopy Dark-field microscopy  (also called  dark-ground microscopy ) describes  microscopy  methods, in both  light  and  electron microscopy . Phase contrast microscopy (PCM) Phase contrast microscopy (PCM) is an optical microscopy technique that uses phase shifts in light passing through a transparent specimen to create brightness changes in the image.

3. Electron Microscopy Electron microscopy (EM) is a technique that uses a beam of electrons to create high-resolution images of biological and non-biological specimens. Luminescent microscope The Bioimaging Facility houses a Photon Imaging Microscope capable of imaging bioluminescent and chemiluminescent indicators on a cellular level. 

4. Actinomycetes are  a diverse group of gram-positive bacteria that can be found in soil, water, air, and extreme environments . 

5. Chlamydia and rickettsia are  both gram-negative bacteria that live inside cells and have defective cell walls for much of their life cycle .  They are categorized together as organisms with properties of both bacteria and viruses,

6. Acid-fast bacilli (AFB), also known as acid-fast bacteria, are a group of bacteria that can resist decolorization from acids during staining procedures.
