Microbiology and parasitology Flashcards
The idea that life arises only from already existing life
Biogenesis
It is the study of the immune system, which protects us from
infection
Imunology
-It is an organism that harbors a guest organism
Host
the study of microscopic and submicroscopic details of
microorganisms.
Microbial cytology
the study of the pathogenic microbes and the role of
microbes in human illness.
Medical microbiology
It is the study of microscopic organisms, such as bacteria,
viruses, fungi and protozoa
Microbiology
It is the study of the molecular principles of the
physiology processes in microorganisms.
Molecular biology
- it is an organism that lives within or on a host.
Parasites
it is the study of parasites, their hosts, and the relationship
between them.
Parasitology
it is a biological agent that causes disease or illness to its hosts
(microbes, germs).
Pathogens
it is the study of protozoa
Protozoology
Advocated washing hands to
stop the spread of disease
Ignas semmelweis
He invented the petri dish.
R.J petri
inactivated, hard to kill, non-reproductive structure produced by
certain bacteria. When the environment becomes more favorable, the endospore
can reactivate itself to vegetative state.
Endospore
First proof of Germ Theory of
Disease with Bacillus anthracis
* Growth of bacteria on solid
media
Robert Koch
Discovered viruses
Dmitri Iosifovich Ivanovski
Recognized viral dependence on
cells for reproduction
Martinus beijerinck
Invented Polymerase Chain
Reaction
Kary mullis
Developed gram stain
Christian gram
Bacteriology - Scientific study of microscopic organisms.
* Kingdom Monera
* Prokaryotic cell
* The first form of life on earth
* Gram+ (with murein in cell wall) Gram- (no murein)
* Pathogens cause disease
* E.coli – causes “euthrophication”
* Probiotics – “good bacteria”
* Oil eating bacteria – “bioremediation”
Backteria
Kingdom Protista
* Eukaryotic Cell
* Animal-like protist
* Ex. Plasmodium, Amoeba
* Motile
* Heterotrophic
* Unicellular
* Phyla:
* Sarcodina- pseudopodia (Amoeba)
* Mastigophora-flagella (Trypanoso ma gambiense)
* Ciliaphora - cilia (Paramecium)
Protozoan
Mycology – scientific study of fungi
* Kingdom Fungi
* Eukaryotic cell
* Saprophytic
Fungi
Virology - It is the scientific study of viruses.
* Acellular, a self- replicating molecule
* 1ª virus discovered tobacco mosaic virus
* Ex. Retrovirus, Coronavirus
* Capsid - Protein coat of virus
Virus
invade only bacterial cells
Backteriophages
Contains DNA as the genetic materials Ex. Viruses that
causes sore throat, warts, herpes, chickenpox and smallpox
DNA virus
Contains RNA as the genetic material. Ex. Viruses that
causes polio, common colds, hepatitis, and rabies4
RNA virus
Contains an enzyme, reverse transcriptase that makes DNA
from RNA. Ex. HIV
Retrovirus
Caused by Human
Immunodeficiency Virus (HIV), a retrovirus
Acquired immune deficiency syndrome
inactivates and destroys the body’s white blood cells, particularly
lymphocytes, or helper T-cells.
HIV
- It is the ability of a pathogenic virus to lie dormant within a cell.
Latency
