colonzization or invasion of pathogens to an organism with active growth and multiplication causes damage to the host

as something which targers our own cell

hiv target cells

normal cdt 4 cell count

aids progression cd4+ cells

types of infection

(as to cause of infection) self inflicted

(as to cause of infection) caused by non living material found in medical setting

(as to cause of infection) supposedly can non post threat unless the immune system is weakened

(as to cause of infection) any infection we can get from hospital

(as to localization) starting point

(as to localization) progression of localized infection - into a larger scope of area

(as to localization) covers the entire system

(as to extent/ degree) one oragnism and is very strong pathogen

(as to extent/ degree) second organism and able to enter becuase of weak state and experiencing primary infection

(as to extent/ degree) multiplex of pathogens

(as to duration) abrupt, sudden type of infection. dominance of pnms or neutrophils

(as to duration) long endured, spans longer duration

(as to duration) infection that is passive type, usally inactive but it is present

(as to duration) type of infection whein is the middleway between acute and chronive infection

routes of infection

(routes of infection) direct exposure to the pathogen

(routes of infection) no straigth forward exposure to the pathogen

same generation, chil-child, mother-mother

two generations, mother to chid

inanimate objects that may act as support system

such as food, water, and air

arthropods and may be protozoans. referred to be smaller

disease of animals transmissable to man

specific illness or disorder with recognizable set of signs and symptoms

a change in a body function that is felt by a patient as a result of disease

a changes in a body that can be measures or observed as a result if disease

a specific group of signs and syptoms that acompany a disease

disease that is brougth by pathogens

classification of infectious disease

(classification of infectious disease) can be transferred

(classification of infectious disease) can be transferred easily

(classification of infectious disease) does not have the capacity to get transferred

phases in infectious disease

(phases of infectious disease) starting point, entry of organism. to recogize the new environment

(phases of infectious disease) onset of signs and symptoms. hallmark or evidence of infection

(phases of infectious disease) peak phase in infection

(phases of infectious disease) signs and symptom starts to disappear

(phases of infectious disease) death or exit of pathogens

organism carrier/ harbors the infected agent

types of carriers

number of occurent in a given period of time

number of people affected/ total population in a given time period

number of deaths from a disease

isolated case

spans a large area

larger area/ scope than endemic

inolves 2 or more countries

microorganisms that causes disease or infection

ability of the pathogen to produce disease to a host

has the capacity to casue infection

does not have the capacity to cause infection

organism by nature can cause disease

organisms can not cause disease to healthy individual

is the relationship between normal microbiota and the host

is a symbiosis in which two organism mutually benefit from each other

is a symbiotic relationship in which two species benefit from the relationship without harming or benefiting the others

is a symbiotic relationship where one organism is benefited at the expense of the other

artificial environmental with many organism living together

is the measure of the pathogenicity of an organism. is the relative ability of a microorganism to cause disease or the degree of pathogenicity

factors that are produced by a microorganism and evoke disease

virulence factors helps the bacteria to:

many pathogenic bacteria colonize mucosal sites bt using pili to adhere to cells

surface components that allow the bacterium to invade host cells can be encoded on plasmids, but more often are on the chromosome

skin, flushing of the urine, structures of body openings

cough, sneeze reflex

lysozymes target the cell wall of bacteria

organism that are normally present in some specific areas of the body

inhabit and multiply months to year

inhabit but does not multiply short period of time

(specific resident flora) mouth and oral cavity

(specific resident flora) upper respiratory tract

(specific resident flora) nasopharynx

(specific resident flora) colon

(specific resident flora) urethra

engulfment of infective agent by a phagocyte

capable of engulfing bacteria

due to population of rbcs in the area. responce of the red blood cells

due to the capillary liquid homeostasis via the action of serum proteins

due to the tumor necrosis factors via the rbcs

due to the pressure of nerve endings cuases by swelling

unseuccessful inflamatory response

ability of the host to mount specific response

two types of toxins
