Dr. Annie Cu Gallardo BSE-Biological Sciences III-3 Microbiology (Lecture) Microbiology Written Report REPORT NO. 1 Prokaryotes: Bacteria Most of us have been conditioned to think of bacteria as invisible‚ potentially harmful little creatures. Actually‚ relatively few species of bacteria cause disease in humans‚ animals‚ plants‚ or any other organisms. In fact‚ all organisms made up of eukaryotic cells probably evolved from bacteria-like organisms‚ which were some

Viable Count is a quantitative idea about the presence of microorganisms such as bacteria‚ yeast and mold in a sample. It counts the number of colonies produced by a very dilute suspension of bacteria on an agar plate and to observe the differential staining behaviour of the living bacteria. This involves counting the colonies produced by viable cells under favourable growth conditions. Some techniques needed before the viable count‚ like pour plate method‚ spread plate method and most probable number

Biology was fascinated me tremendously particularly when I was introduced to field of microbiology. I used to wonder how these primitive microbes grow and communicate with each other. Theoretical knowledge of microbiology grabbed my attention and made me curious about these tiny microbes which we cannot be seen through our naked eyes. Therefore I decided to pursue my higher studies and specialisation in microbiology. I started my graduation

Labset Four Worksheet 1. Define the term “selectively toxic.” Why is it an important feature of antimicrobial agents? A substance or drug is selectively toxic if the agent used in it is able to kill the microorganism that it is meant to without harm to the host that has taken the drug. This is very important to microbial agents in that it enables these agents to inhibit a microorganism by interacting with microbial functions or structures different from those of the host; thereby showing little
