What is microbiology Slideshare?
Microbiology: Microbiology is the science that dealing with the study of microorganisms. Microorganisms: An organism that can be seen only with the aid of a microscope and that typically consist of only a single cell.
What are the basic concepts of microbiology?
Microbiology is the study of all living organisms that are too small to be visible with the naked eye. This includes bacteria, archaea, viruses, fungi, prions, protozoa and algae, collectively known as ‘microbes’.
What is the history of bacteria?
Bacteria have existed from very early in the history of life on Earth. Bacteria fossils discovered in rocks date from at least the Devonian Period (419.2 million to 358.9 million years ago), and there are convincing arguments that bacteria have been present since early Precambrian time, about 3.5 billion years ago.
What does an e mean on a microbiology test?
The counts are TNTC (Too Numerous to Count) and therefore are reported as more than (>) the upper countable range of the test. Where counts exceed the recommended countable range, but are able to be counted, the result will be reported with an ‘E’ to indicate that the count is outside of the recommended countable range.
How is streak plate method used in microbiology?
Streak Plate Method- Principle, Methods, Significance, Limitations In microbiology, streaking is a technique used to isolate a pure strain from a single species of microorganism, often bacteria. The dilution or isolation by streaking method was first developed by Loeffler and Gaffky in Koch’s laboratory, which involves …
How are biochemical tests used to identify microorganisms?
Biochemical tests can be used to identify the type of metabolism a microorganism uses based on the products it makes from defined substrates. Bergey’s Manual of Systematic Bacteriology is used to identify bacteria based on microscopy, ability to grow on specific media, appearance of colonies, and biochemical tests of metabolism.
