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