STS - Final Exam (Microbio)

Intro to Microbio

Anton van Leeuwenhoek

Designed a single lens microscope and demonstrated the little agents of disease, which he designated as animalcules

Louis Pasteur

A French chemist who generated strong evidence to disprove the theory of spontaneous generation. He also solidified the germ theory of disease by proving hat it is microorganisms that causes the diseases in silkworm

Joseph Lister

He was a British surgeon and pioneer of antiseptic surgery

Alexander Fleming

Discovered Penicillin on 1928, discovered also antibacterial agent, Lysozyme

Robert Koch

He is a German physician and microbiologist. He was hailed as the founder of modern bacteriology. He also discovered the causative agents of Anthrax, Cholera, and Tuberculosis.

Virus

Smallest of all microbes ; requires host cell to replicate ; causes range of diseases

Prokaryotes

Bacteria and Archaea are referred to as _____

True

True or False: Bacteria and Archaea are unicellular and have no membrane bound organelles

Metabolically Inert

Viruses are _______ meaning no metabolic activity outside host cell ; must enter host cell to replicate

Bacteriophage

Bacterial viruses ; composed of nucleic acid encapsulated inside a protein or lipoprotein coat

Fungi

Eukaryotic ; Can be unicellular or multicellular ; Obtain nutrients through absorption ; Similar to both plants and animals

True

True or False: Yeast is a unicellular type of Fungi

True

True or False: Mold is a multicellular type of Fungi

Protists

Are eukaryotes that are not animals, plants or fungi

Parasites

are organisms that live in or on another organism (host) and harms them

Immunity

The ability of the body to fight infection and/or foreign invaders by producing antibodies or killing infected cells.

Immune System

The system in the body responsible for maintaining homeostasis by recognizing harmful from non-harmful organisms and produces an appropriate response

Immune Defense

Our immune system fights of pathogens to prevent infection'/disease

Immune Homeostasis

Our Immune System, aside from pathogens, eliminates injured and senile cells while leaves other healthy cells alone

Immune Surveilance

Our Immune System patrols and monitors our body and also destroys mutated/transformed cells

White Blood Cells

Cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders

5 Major Types of WBC

Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils

Vitamins

Bacteria are grown in a bioreactor to produce _________

Antimicrobial Resistance

AMR Stands for?

Cyanobacteria

Domain Bacteria : ________ produce significant amounts of oxygen

True

True or False: Domain Bacteria lack a membrane bound nucleus

Domain Archaea

Distinguished from Bacteria by unique rRNA gene sequences

False

True or False: Domain Bacteria lack peptidoglycan in cell walls while majority of Domain Archaea have cell wall with peptidoglycan

True

Protists are generally larger than Bacteria and Archaea

Domain Eukarya

What domain is Algae under?

Protozoa

May be motile, “ hunters, grazers “

Viroids and virusoids

Infectious agents composed of RNA
