Study Notes

Human and Microorganism Interactions

Humans have been using microorganisms for thousands of years to improve life and shape civilizations, including using yeast to make bread, wine, and cheese.
Early Egyptians used moldy bread to treat wounds before penicillin was discovered.
Biotechnology is a modern method that manipulates microorganisms to create products like insulin.
Humans extract human insulin protein to produce the hormone needed for injections via genetic engineering.

Microorganisms and Human Disease

Microorganisms cause numerous human diseases.
The difference in disease rates between developed and developing nations is an important consideration.
Microbiologists study microbes' structure, function, growth, physiology, genetics, taxonomy, evolutionary history, interactions with environments, and interactions with humans.
Public health microbiology and epidemiology monitor and control the spread of diseases within communities.
Examples of public health agencies include the CDC and the WHO.
Historical examples of microbiologists include David Bruce who discovered the microorganism that causes Malta fever.
Infectious diseases are caused by pathogens, agents such as viruses, bacteria, fungi, parasites, and prions, which cause harm.
Example pathogens include the microorganism causing malaria, which is transmitted by mosquitoes.

Modern Applications of Microbiology

Industrial microbiology safeguards food and water, creating amino acids, drugs, enzymes, vitamins, and more.
The process also uses microbes to create enzymes and vitamins.
Agricultural microbiology studies microbe-plant relationships.
Environmental microbiology investigates how microbes impact diverse earth environments.

Taxonomy

Taxonomy classifies organisms using a hierarchical system.
The Linnaean system, named after Carl Linnaeus, uses broader and broader groups to classify organisms.
The Linnaean system is used to classify organisms from broader groups like domain to the most specific category like species through genus, family, order, class, phylum.
Example classifications include using the species Canis lupus familiaris to refer to a domesticated dog, in which Canis being a genus and lupus a subspecies.
