Small circular extra-chromosomal DNA that is nonessential. It replicates separately from the chromosome and often codes for virulence factors, antibiotic resistance, and/or self tr
Phase on bacterial growth curve where the is no or little cell division
Gram negative pathogen that causes Lyme disease. It is a spirochete that contains endoflagella for movement. Gram negative stain but too thin to be seen.
Single polar flagellum
Multiple flagella around the cell
Transfer of naked DNA
Dormant form of a bacterial cell found only in gram positive bacteria. Examples are Bacillus anthacis and Clostridium Tetani.
Type of parasite that can live only on living tissue and not dead tissue
Pathogen that does NOT have a cell wall, will not be seen with a gram stain, and contains sterols.
Major surface antigen on LPS
G+ pathogen that causes Gas Gangrene. It is an obligate anaerobe.
Grows best when O2 is present, but can grow without O2 as well. E. coli is an example.
Small segments of DNA that can move from one region of DNA to another
Toxic part of LPS
Bind to RNA polymerase core enzyme and recognize promoter.
Also called endotoxin specific to Gram negative bacteria. It is a strong stimulator of the immune response.
Surface antigens only on Gram positive bacteria that has a role in adherence to host cells or other bacteria.
May be a poison for bacteria because it generates toxic products such as hydrogen peroxide and superoxide anion.
Complex aggregation of microorganisms marked by the excretion of a protective and adhesive matrix. 65% of nosocomial infections are caused by this.
Multiple flagella at the same spot
Transport against the concentration gradient. Carrier protein and energy are required.
Provides protection for DNA in spores.
Gram negative pathogen that causes UTI, Meningitis in neonates, and GI tract infections.
Respiration in which an inorganic molecule other than O2 is the final electron acceptor. Theoretical maximum energy yield is 36ATP/glucose or less.
Incorporation of extrachromosomal DNA into the chromosome.
Gene transfer through the sex pilus
Simultaneous expression of genes involves this.
Unusual carbohydrate residue on LPS
Occurs in the cytosol in the absence of O2 and energy yield is 2ATP/glucose. End products of this process can be used for identification of many bacteria.
Peptidoglycan like on spores
Where a regulator protein binds in an operon.
Phase on bacterial growth curve where rate of cell division is equal to the rate of cell death
Keratin-like protein on spores.
Another name for glycocalyx.
Chemical conversion of transported molecule
Gram positive diplococci that causes pneumonia, otitis media, and meningitis.
Type of diffusion where a protein channel or carrier protein is embedded within the cell membrane
Repressed temperate phage DNA inserted into bacterial chromosome. Its DNA may code for other proteins that make the bacteria more virulent=lysogenic conversion. Examples are diphth
Set of genes needed for a particular response that are in different operons but under the control of one common regulator protein.
Has a waxy cell wall containing mycolic acid. Its lethal oxidation is survival inside of a macrophage. It is sensitive to heat and UV light.
Viruses that infect bacteria
Gram negative pathogen that causes meningitis, epiglottitis, otitis media, and pneumoniae.
Small molecules that bind iron. Gets internalized via receptors by the bacterial cell.
Gram positive pathogen that causes skin infections, endocarditis, pneumonia, and food poisoning.
Recognizes and binds to specific DNA sites during transcription
Phage-mediated gene transfer
