classic lesion of staph aureus

enflamed hair follicle due to staph aureus

blood clots and is walled off due to this enzyme

caused by exfoliative toxin that gets between dermis and epidermis and causes epidermis to slough off

super antigen toxin which causes septic shock

S/ aureus and S. epidermidis which are normal flora can lyse blood cells and form biofilms; associated with implanting a device

has mac cassette which carries resistance to many different antibiotics

strep infection of subdermal fat which causes inflammation of fat tissue

strep infection which causes late seuelae

"follow on" caused by immune mimicry

Super antigen toxin that allows the bacteria to spread quickly due to tissue invasive protease

sensitive to penicillin

caused by borrelia burgdoferi, a spirochaete, has a bulls eye rash; late sequalae is heart conduction abnormalities or arthritis (immune mimicry); spread via tick

caused by anaerobic spore former clostridium tetani which infect a deep tissue wound; AB toxin that inhibits release of neuroinhibitor so all muscles contract

AB toxin of tetanus that causes rigid paralysis

allows muscle to relax while others contract

vaccination with tetanus toxoid

antitoxin

caused by the anaerobic spore former clostridium perfingens which produces gas which puts pressure on capillary and stops blood flow (ischemia) and leads to tissue death

cutting out of dead tissue

rapid swelling due to animal bite

Herpes virus, enveloped, dsDNA

flat spots in the skin durin chicken pox

fluid filled blisters in chicken pox

crusty broken papulo during chicken pox

If aspirin is taken while you have chicken pox this occurs

ssRNA enveloped virus with flat rash; replicates in Tcells so cullular immunity is compromised, symptoms include cough, coryza, conjunctivitis and Kiplik's spots

cough, runny nose, and pink eye characteristic of measles rupeola

white spots in pharynx due to measles rubeola killing cells

measles, mumps, rubella vaccine that requires 2 injections

small enveloped ssRNA togavirus with milder symptoms

when fetus aquires rubella from mother and can be born blind, deaf, retarded, with heart disease, or still born

small naked dsRNA that can survive outside host; 18 month incubation period; replicates in epithelial cell nuclei and causes abnormal growth

cutaneous fungal infection painful itchy burning rash

type of candida that grows orally

keratinase; athletes foot and other tinea infections

dermatophytes that live below keratine

fungal disease which charges from spores to yeast; migrate along lymph duct; found in gardening
