-number of organisms -virulence of the organism -competence of the person's immune system -length & intimacy of the contact between the person & the microorganism

an organism's potential to produce disease in a person depends on a variety of factors, including:

rod shaped bacteria

bacilli

spherical shaped bacteria

cocci

plant-like organisms (i.e., molds or yeasts) that also can cause infection, are present in the air, soil, & water, e.g.= athlete's foot, ringworm, & yeast infection, & treated with antiviral meds-BUT many infections caused by this are resistant to treatment

fungi

this type of bacteria has chemically more complex cell walls & can be decolorized by alcohol; thus it does not stain

gram-negative

this type of bacteria has a thick cell wall that resists decolorization (loss of color0 & are stained violet

gram-positive

describes a disease state that results from the presence of pathogens in or on the body

infection

this occurs as a result of a cyclic process consisting of 6 components

infection

organisms that live on or in a host & rely on it for nourishment, e.g. = malaria

parasites

disease-producing microorganisms

pathogens

corkscrew shaped bacteria

spirochetes

the smallest of all microorganisms, visible only with an electron microscope, & cause many infections (e.g., common cold, hep B & C, AIDS). Antibiotics have no effect on this

virus
