Lophotrichous
Small bunches arising from one end
Both end of cell
Flaggella disperesed over the surface
Peritrichous
Flagella at both ends
Flagella disperesed over the surface
Single flagellum at one end
Flagella are shorter and straighter than pilli
True
False
Flagella are hair like structure
True
False
Organs of motility
Flagela
Pilli
Antigenic determinent
Flagella
Pilli
Sex pili
Relatively long and found in few numbers
Short and many 200
Major determininat in bacterial virulence
Pathogen attach to tissue
Resist attack by phagocytic white blood cells
Sex pili
Involved on conjugation
Provide the means of attachment to host hosf cells
Gel like consistency molecules pass through it rapidly
Cytoplasm
Bacterial genetic material
Bacterial genetic material
Surrounded by the nuclear membrane
Located in nuclear membrane
Not surrounded by nuclear membrane
Large circular genome
Plasmid dna introder
Small circular
Essential for viability
Transfered form o w bacteria to another
Dont Carry extra gene
Storage granules
Nutrients are in short supply
Excess carbon in the form of glycogen
Polyphosphate inclusions are reserves of po4 and energy
Sulfur granules
Gas vacule introder
Control buoyancy
Excertion of waste material in the form of microbe pee
Sulfur granules
