Lecture 1 & 2: A glimpse of Microbiology

What are Microbes you say?

Bacteria, algae, yeast, helmins, molds, protozoa, viruses

Where and how do they live?

Microbes are found everywhere, the ocean, the counters, inside of you, and the list goes on. They live simply by eating, growing, and dividing.

Microbial antagonism is their tactic of being competitive with other organisms. It may modify metaolism, make toxins (ie. botulism, anthrax), modify their structure (ie. producing a spore so that when the environment becomes nutrient deficient or competitive, the spore is developed with a protein surrounding allowing the organism to stay dormant until nutrients are available again)

Note: spores are spread through the air, hence, don’t sniff a bag of mold!

Not all of these microbes are pathogenic some may be nonpathogenic (not causing diseases). They also have long names that are categorized and classified by looking at the taxonomy (created by an 1800s botanist, Lineus), which gives it its binomial nomenclature (genus & species).
