P
The science, dealing with the description, identification, naming, and classifying of organism
Taxonomy
A chemical secreted by a living organism that kills or reduces the reproduction rate of other organism
Antibiotic
A thick internal wall, make of several hard layers, produced by the bacterium, that encloses its DNA and other essential parts
Endosphere
Naming an organism with its genus and species name
Binomial nomenclature
An organism that feeds on dead matter
Saprophyte
A temporary union of two organisms for the purpose of DNA transfer
Conjugation
The process in which infection by a virus, results in DNA being transferred from one bacterium to another
Transduction
A Non cellular infectious agent that has two characteristics
Virus
An agent that must infect a living cell in order to reproduce
Virus
The transfer of a DNA segment from a non-functional donor cell to that of a functional recipient cell
Transformation
A virus entering a cell, hijacks the host cells DNA replication system, makes copy of itself, and causes the cell to burst releasing more viruses
Lytic cycle
Infectious agent that is composed of genetic material inside a capsid or protein coat
Virus
The taxonomic classification groups used by scientists, in order
Domains, kingdoms, phylum, class, order, family, genus, species
Bacteria are usually found in one of these three bodies shapes
Coccus, bacillus(rod), spirillum(spiral)
A virus enters a cell, embeds its DNA into the DNA of the host cell and is replicated along with the host cell’s DNA
Lysogenic cycle
It is called the asexual reproduction in a bacteria
Binary fusion
The composition that helps bacteria survive in a dehydrated food.
Endospores
Three places in the body that bacteria is present
Mucus membrane, skin, digestive tract
Bacteria that requires a constant supply of oxygen for cellular respiration
Obligate aerobes
A bacterium that has a cell wall with a thick layer of peptidoglycan that stains, blue purple
Gram-positive bacterium
Bacteria that cannot live in the presence of oxygen
Obligate anaerobe
Toxin produced by pathogenic bacteria that is part of bacterial growth and metabolism
Exotoxin
The best way to prevent spread of infection
Good hygiene
A poisonous lipid found in a bacterium’s cell wall when the bacteria dies that is produced by pathogenic bacteria.
Endotoxin
A weakened or an active version of a pathogen that stimulates the body’s production of antibodies that aid in destroying the pathogen
Vaccine
