BACTERIA

normal flora

any microbe that lives on or in us (first line of defense part of our nonspecific immune defense)

what does normal flora do

take up space, and take up nutrients

pathogen

any organism that has ability to cause disease

non- pathogens

organism with no ability to cause disease based on genetic makeup

frank pathogen/ primary

cause disease when they are present

opportunistic pathogen

ability to cause disease but conditions MUST be ideal

why are babies born with no normal flora

develop in a sterile environment

when do babies start to get colonized

during vaginal delivery encounter microbes with mothers vaginal tract

when do babies develop normal flora

6 weeks to few months

immunocompetent / immunonormal

a healthy person with a fully functioning immune system

immunocomprimised

weakened immune system from fighting/ recovering from infection (tired)

immunosuppressed

someone whose immune system functions but sensitivity is lessened through medication or natural condition

immunodeficient

no functioning immune system

aceae

family

micrococcacaeae family

micrococcus and staphlyococcos

gram positive, catalise positive, coccoid, pigment producers

what is catalase positive

enzyme that breaks down hydrogen peroxide to water and oxygen

if it has catalase it also has..

peroxidase and superoxide dismutase

what is coagulase

Causes fibrin to coagulate into a clot

micrococcus family is

gram positive, catalase positive, couaglase negative, grow in tetrads, nonpathogenic

micrococcus luteus

found in extremities (fingers and toes) pants and soil

like cooler temperatures

nonpathogenic

normal skin flora

staphylococcus family

gram postive

catalase positive

grape like cluster

normal flora opportunistic pathogen

staphylococcus saprophyticis (honeymooners disease)

opportunistic

found in normal flora and mucosa of genitourinary tract

infection in sterile urinary tract through sexual contact or shared bathroom facitilites

seen more in sexually active young women

symptoms UTI rare cases kidney infection

staphylococcus epidermis

normal flora or mucous membranes

low number found in respiratory system

nonpathogenic in epidermis but can be found in wound due to associate with skin

NO infection by itself

carditas

inflammation of heart risk of cardiac arrest

meningitis

inflammation of meningitis the protective membranes that cover the brain and spinal cord

arthritis

inflammation of joint due to bacterial infection or injury

surgical procedure to the torso or abdomen or when a blood clot carrying S. aureus inside it travels directly to the heart

pneumonia

fluid accumulation of the lungs

boil

pus filled ball

impetigo

small red bumps that look like pimples or blisters, usually around the bottom of the nose, mouth, or eyes

scalded skin syndrome

cracked, red, and peeling, resembling a severe burn or scalding on the face or upper torso

nosocomial infection

a hospital-acquired infection that is completely unrelated to the original reason for a patient's hospitalization
